Overview
2.1
Introduction
This chapter introduces the Trimble R7 GPS receiver. This receiver is
designed for GPS surveying applications. The receiver features
one-touch logging for ease of use, and five LEDs that let you monitor
the survey in progress and the available battery capacity.
The Trimble R7 tracks GPS satellites on both the L1 and L2
frequencies to provide precise position data for land survey
applications. The receiver records GPS data on an internal
CompactFlash card and makes all data available through serial or USB
ports.
You can use the Trimble R7 alone by logging data internally, or as part
of the GPS Total Station® system, which logs GPS data from the
receiver to a Trimble controller running the Trimble Survey
Controller™ or Trimble Survey Pro™ software.
2.2
Features
The receiver provides the following features:
•
•
•
Trimble R-track technology, which allows the receiver to track
the L2 Civil signal (L2C)
Centimeter-accuracy real-time positioning with RTK/OTF data,
and up to 10 Hz position updates
Submeter-accuracy real-time positioning using pseudorange
corrections
•
•
Adaptive dual-frequency RTK engine
WAAS/EGNOS capability (Wide Area Augmentation
System/European Geo-Stationary Navigation System)
•
•
•
Automatic OTF (on-the-fly) initialization while moving

The Trimble R7 is designed to withstand the rough treatment that
typically occurs in the field. However, the receiver is a high-precision
electronic instrument and should be treated with reasonable care.
C
WARNING – Operating or storing the receiver outside the specified
temperature range can damage it. For more information, see Physical
specifications, page 80.
High-power signals from a nearby radio or radar transmitter can
overwhelm the receiver circuits. This does not harm the instrument,
but it can prevent the receiver electronics from functioning correctly.
Avoid using the receiver within 400 meters of powerful radar,
television, or other transmitters. Low-power transmitters such as those
used in cellphones and two-way radios normally do not interfere with
receiver operations.
For more information, contact your local Trimble distributor.

COCOM Limits
The U.S. Department of Commerce requires that all exportable GPS
products contain performance limitations so that they cannot be used
in a manner that could threaten the security of the United States. The
following limitations are implemented on the Trimble R7 receiver.
Immediate access to satellite measurements and navigation results is
disabled when the receiver’s velocity is computed to be greater than
1000 knots, or its altitude is computed to be above 18,000 meters. The
receiver continuously resets until the COCOM situation is cleared.

General guidelines
The following guidelines apply whenever you set up your receiver for
operation:
•
When plugging in a Lemo cable, make sure that the red dots on
the receiver port and the cable connector line up. Never use
force to plug cables in, as this may damage the connector pins.
•
When disconnecting a Lemo cable, grasp the cable by the
sliding collar or lanyard and pull the cable connector straight
out of the port. Do not twist the connector or pull on the cable
itself.
•
•
To securely connect a TNC cable, align the cable connector
with the receiver receptacle and thread the cable connector onto
the receptacle until snug.
Insert the internal batteries with the battery contacts facing the
CompactFlash/USB door. The undersides of the batteries have a
center groove for alignment when being inserted into the

3.1
Pole-Mounted Setup
To mount the Trimble R7 on a pole, you need to do the following:
1. Mount the eRTK™ Range Pole antenna (RPA).
2. Mount the receiver.
3. Mount the Trimble controller.
This section provides detailed instructions on each of these three steps.
Mounting the Range Pole antenna (RPA)
To mount the RPA on the pole:
1. Install the RPA bracket 7.5 cm (3") from the pole top by placing
the two pieces together and securing with screws. If you are
using a 1" diameter pole, place the bracket inserts inside the
bracket before securing.
Note – You can use a quarter-wave whip (“rubber duck”)
antenna attached directly to the receiver instead of the RPA.
2. Connect the yellow TNC-to-TNC GPS cable and run it through
the RPA bracket clips where it is labeled on the bracket. Make
sure that the right-angle connector is at the top.
Note – The cable must be routed inside the RPA, through the
bracket, or it will affect the RPA radio reception performance.
3. Align the TNC connector on the RPA with the GPS antenna
cable on the bracket, and while feeding the cable through the
RPA, slide the RPA onto the bracket until it clicks.

Antennas
The Trimble R7 receiver should normally be used with a Zephyr or
Zephyr Geodetic antenna. These antennas have been designed
specifically for use with the Trimble R7.
Use Figure 3.14 as a guide for measuring the height of the Zephyr and
Zephyr Geodetic antennas. The Zephyr antenna is designed to be
measured to the top of the notch. The Zephyr Geodetic (shown) has
been designed to be measured to the bottom of the notch.
Figure 3.14 Measuring antenna height
Older models of antennas, such as the Choke Ring or
Micro-Centered™ L1/L2 antennas, need more power to operate than
the Zephyr models. To configure the receiver to output more power on
the antenna port, select the correct antenna type in GPS Configurator,
or through the Trimble controller. For information on how to do this,
contact your local Trimble Service Provider.

CompactFlash cards
The Trimble R7 logs data internally on a CompactFlash card.
However, it only support the Type I CompactFlash card. Trimble
recommends that you use an industrial-rated CompactFlash card, as
commercial cards have a limited operating temperature range.
Before logging data to a CompactFlash card, format the card to ensure
the integrity of the file system. To format the card, insert it in the
receiver and then hold down p for 30 seconds.
Note – Make sure that you format your CompactFlash card in the
receiver. This prevents data on the card from being corrupted if the
card is removed while data is being logged. Formatting the card in
your PC may cause data corruption, or loss of data.
When inserting the card, make sure that it slides into the card slot
properly.
WARNING –
C
– The Trimble R7 allows for a maximum of 512 files on the CompactFlash
card, regardless of the card’s capacity. The file names must be in 8.3

45.2
Logging to a Trimble controller
When the Trimble R7 receiver is connected to a Trimble controller,
you can log GPS data from the receiver to the controller, or to a PC
card inserted in the controller. When you use a Trimble controller, you
do not use the receiver’s controls. Instead, you use the controller
functions to set logging options, specify filenames, and control when
logging occurs.
Data is stored in job files, which can be transferred to your office
computer using Trimble’s Data Transfer utility.
For more information on logging data from a receiver using a Trimble
controller refer, to the user guide for your particular controller.

Batteries and Power
WARNING – Do not damage the rechargeable Lithium-ion battery. A
damaged battery can cause an explosion or fire, and can result in
personal injury and/or property damage.
C
To prevent injury or damage:
– Do not use or charge the battery if it appears to be damaged. Signs of
damage include, but are not limited to, discoloration, warping, and leaking
battery fluid.
– Do not expose the battery to fire, high temperature, or direct sunlight.
– Do not immerse the battery in water.
– Do not use or store the battery inside a vehicle during hot weather.
– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.
The Trimble R7 can be powered either by its two internal batteries or
by an external power source connected to Port 2 or Port 3. The charge
provided by the internal batteries depends on the type of survey and
operating conditions. Typically, one battery provides about 3.5 hours
of power during an RTK survey using the internal radio, and about
5 hours during a survey without the internal radio.
The external power source is always used in preference to the internal
batteries. When there is no external power source connected, or if the
external power supply fails, the internal batteries are used. The
internal batteries are drained in turn, and the receiver automatically
switches to the full battery when the first battery is drained.
If no external power is supplied and both internal batteries are drained,
none of the data that you have logged is lost. When internal or external
power is restored, the receiver restarts in the same state as when power
was lost. For example, if the receiver was logging data, the data file is
not corrupted, and when power is restored the receiver resumes
logging with the same settings as before.

General Operation
Charging the Lithium-ion battery
The rechargeable Lithium-ion battery is supplied partially charged.
Charge the battery completely before using it for the first time. If the
battery has been stored for longer than six months, charge it before
use.
To protect the battery from deep discharge (5 volts or less), the
Trimble R7 system is designed to switch batteries or cease drawing
power when the battery pack discharges to 5.9 volts.
A battery that has reached the deep discharge level cannot be
recharged and must be replaced. The following recommendations
provide optimal performance and extend the life of your batteries:
•
•
•
Fully charge all new batteries prior to use.
Do not allow the batteries to discharge below 5 volts.
Keep all batteries on continuous charge when not in use.
Batteries may be kept on charge indefinitely without damage to
the receiver or batteries.
•
•
Do not store batteries in the receiver or external charger unless
power is applied.
If you must store the batteries, fully charge them before storing
and then recharge them at least every three months.
Disposing of the rechargeable Lithium-ion battery
Discharge the Lithium-ion battery before disposing of it. When
disposing of the battery, be sure to do so in an environmentally
sensitive manner. Adhere to any local and national regulations
concerning battery disposal or recycling.
48.2
Operating with the TSC1/TSCe controller
If the receiver is being powered by its internal batteries, it does not
supply power to the TSC1/TSCe controller when they are connected.

General Operation
You can use GPS Configurator or Trimble Survey Controller to enable
power output on Port 3. Port 3 can be enabled for power output
regardless of whether power is supplied internally or externally.
On Port 3, the output voltage is approximately 0.5 V less than the
input voltage. For example, if power is being supplied from the
internal Lithium ion batteries, the maximum battery voltage is 8.4 V,
so the maximum output voltage is 7.9 V.
Note – When you start a survey using Trimble Survey Controller, and
you are using an external radio, the software automatically enables
power output on Port 3.
48.4
Firmware
A receiver’s firmware is the program inside the receiver that makes the
receiver run and controls the hardware. When you need to upgrade the
firmware for your Trimble R7 receiver, Trimble recommends that you
use WinFlash. For more information, see WinFlash Software, page 71.
WARNING – Upgrading the firmware deletes all application files on the
Trimble R7 receiver.
C
An alternative method of upgrading your firmware is to copy the .elf
file directly to the CompactFlash card from your computer.
To do this:
1. Connect the CompactFlash card to your desktop computer.
2. Using Windows Explorer, copy the .elf file from your computer
to the CompactFlash card.
3. Disconnect the CompactFlash card from your computer and
insert it into the receiver.
4. Turn the receiver off.
5. Hold down d and press p.

5.1
Introduction
The Trimble R7 receiver has no controls for changing settings. To
configure the receiver, use external software, such as the GPS
Configurator or Trimble Survey Controller software.
There are two ways to configure the Trimble R7:
•
•
Configuring the receiver in real time
Applying the settings in an application file
This chapter provides a brief overview of each of these methods, and
describes the contents and use of application files.
5.2
Configuring the Receiver in Real Time
The GPS Configurator and Trimble Survey Controller software
support real-time configuration of the Trimble R7 receiver.
When you configure the receiver in real time, you use one of these
software applications to specify which settings you want to change.
When you apply the changes, the receiver settings change
immediately.
Any changes that you apply to the receiver are reflected in the Current
application file, which is always present in the receiver. The Current
application file always records the most recent configuration, so if you
apply further changes (either in real time or using an application file)
the Current file is updated and there is no record of the changes that
you applied originally.
For more information on configuring the receiver in real time, see
Chapter 7, Software Utilities.

5.3
An application file contains information for configuring a receiver. To
configure a receiver using an application file, you need to create the
application file, transfer it to the receiver, and then apply the file
settings. GPS Configurator does this for you automatically when you
work with configuration files.
For more information on applying application files, see Chapter 7,
Software Utilities.
5.4
Application Files
An application file is organized into records. Each record stores
configuration information for a particular area of receiver operation.
Application files can include the following records:
•
•
•
•
•
•
•
•
•
•
•
•
File Storage
General Controls
Serial Port Baud/Format
Reference Position
Logging Rate
SV Enable/Disable
Output Message
Antenna
Device Control
Static/Kinematic
Input Message
Timed Activation
An application file does not have to contain all of these records. When
you apply an application file, any option that is not included in the
records in the file remains at its current setting. For example, if you

Configuration
apply an application file that only specifies the elevation mask to use,
all other settings remain as they were before the application file was
applied.
You can store up to twenty different application files in battery-backed
memory on the receiver. You can apply an application file’s settings at
the time it is transferred to the receiver, or at any time afterwards.
54.1
Special application files
The Trimble R7 has three special application files, which control
important aspects of the receiver’s configuration.
The default application file (Default.cfg) contains the original receiver
configuration, and cannot be changed. This file configures the receiver
after it is reset. You can reset the receiver by holding down p for at
least 15 seconds, or by using the reset option in GPS Configurator.
For more information on the default receiver settings, see Default
Settings, page 85.
Although you cannot change or delete the default application file, you
can use a power up application file to override any or all of the default
settings.
Current application file
The current application file (Current.cfg) reflects the current receiver
configuration. Whenever you change the receiver’s configuration,
either in real time or by applying an application file, the current file
changes to match the new configuration.
You cannot delete the current file or change it directly, but every
change to the receiver’s current configuration is applied to the current
file as well.

Configuration
5
When you switch off the receiver then turn it on again, all the settings
from the current application file are applied, so you do not lose any
changes that you have made. The only exceptions are the following
logging parameters:
•
•
•
Logging rate
Position rate
Elevation mask
These parameters are always reset to the factory default values
whenever the receiver is switched off.
Power Up application file
The power up application file (Power_up.cfg) is optional. If a power
up file is present, its settings are applied whenever the receiver is
powered up.
In this file, you can specify that the receiver is reset to defaults before
the power up settings are applied. This ensures that restarting the
receiver always results in the same configuration. This method is
useful for defining “default” settings for the receiver that differ from
those in the default file, which cannot be changed.
Alternatively, you can specify that the power up settings are applied
immediately after the current application file’s settings have been
applied. Restarting the receiver results in a configuration that uses
your default settings for the options you define in the power up file,
but the current settings for all other options.
By default, there is no POWER_UP application file on the receiver. To
use a power up application file, you must create and save a
POWER_UP application file in GPS Configurator. If you save this file
to disk, the file is called Power_up.cfg. The extension .cfg is used by
convention to identify application files on the office computer. When
you transfer this file to the receiver, the file is saved on the receiver as
POWER_UP, and becomes the new power up file.
The power up file is the only special application file that you can
overwrite or delete from the receiver.

Configuration
54.2
Timed application files
A timed application file contains a Timed Activation record which
specifies when this file is to be applied. The main use of a timed
application file is to automatically start or stop logging at a predefined
time.
The Timed Activation record specifies:
•
the UTC date and time when the application file is to be applied
for the first time
•
the interval at which the file is to be reapplied
If you do not specify a repeat interval, the settings are applied only
once, at the specified time. If the file specifies a repeat interval, the
file’s settings are reapplied at the specified interval until the file is
deactivated.
Note – If the receiver is logging continuously, the current logging
takes precedence over any timed application file stored in the receiver.
Defining timed application files
To send timed application files to a Trimble R7, set up scheduled
survey sessions in GPS Configurator. You can define multiple
sessions, each specifying:
•
basic logging parameters (data logging rate, position logging
rate, and elevation mask)
•
•
a starting time
a duration
When you apply the current settings in GPS Configurator, each
defined survey session is sent to the Trimble R7 as a pair of timed
application files: the first includes the logging settings and start time,
and the second contains settings that stop logging at the end time
(which is calculated automatically from the duration you specify).
For more information on scheduled survey sessions, refer to the GPS
Configurator Help.

Configuration
5
The receiver can store up to 20 application files, so you can define a
maximum of 10 scheduled survey sessions (10 pairs of start/stop timed
application files).
Sleep mode
Whenever you press p to turn off the Trimble R7, it checks for a
timed application file that is due to be activated in the future. If one
exists, the receiver goes into Sleep mode instead of powering down.
In Sleep mode, the yellow Logging/Memory LED flashes every three
seconds. The receiver wakes up five minutes before the scheduled
activation time, so that it is ready to begin logging at the scheduled
time.
54.3
Applying application files
An application file’s settings do not affect the receiver’s configuration
until you apply the application file. You can do this at the same time
that you save the file. Alternatively, save the file on the computer or in
the receiver, then open it later and apply its settings.
Note – If the application file is a timed file, its settings do not take
effect as soon as you apply the file, but at the time that the file specifies
for its activation.
54.4
Storing application files
You can store application files that you create in GPS Configurator on
the receiver and on the computer. For example, each file can represent
a different user sharing the same receiver, or a particular mode of
operation or survey style. Saving application files on your computer as
well as in your receiver is optional, but it is useful because:
•
it gives you a permanent copy of the settings you have sent to a
receiver, for audit or your own reference.

Configuration
•
•
you can use the same file to configure multiple receivers
identically.
you can use an existing application file as a template for
creating other application files with similar settings.
54.5
Naming application files
The application filename in the office computer and in the receiver is
always the same. This makes it easier to recognize and keep track of
your application files.
When you change the name of the application file in the receiver, this
changes the application filename on your computer. When you
transfer an application file from the receiver and save it to the
computer, the system renames the file to match the internal receiver
file. However, if you use Windows Explorer, for example, to change
the .cfg filename on the computer, this does not change the internal
receiver filename. This means that the GPS receiver does not
recognize the change to the filename on the computer.

Transferring Data
Transfer the data files to the computer using the Trimble Data Transfer
utility. You can run this utility as a standalone program or from within
Trimble Geomatics Office. For more information about the transfer
process, refer to the Data Transfer Help.
Note – When you connect to a receiver in the Data Transfer utility, you
must use a GPS Receiver (R/5000 Series) device definition. If you use
a GPS Receiver (4000 Series) device definition, the Data Transfer
utility will be unable to establish communication with the receiver.
When transfer is complete, the Data Transfer utility automatically
converts the file to the DAT format. If you are using Data Transfer
from within Trimble Geomatics Office, the Check-in dialog appears.
For more information, refer to the Trimble Geomatics Office User
Guide.
Note – A file in DAT format is approximately six times the size of the
corresponding file in the Trimble R7 internal format. Before
transferring files, make sure that there is enough space on your
computer.

Transferring Data
6.4
Transferring Files Directly from a CompactFlash
Card
All data is stored in a Trimble R7 receiver on an internal
CompactFlash card. There are two ways to transfer files between the
receiver and the office computer:
•
Connect the receiver to the office computer and use the Data
Transfer utility to transfer files.
•
Remove the CompactFlash card from the receiver and connect it
directly to your office computer, where it functions like a
normal disk drive. Use Windows Explorer to transfer files.
When you use the Data Transfer utility to transfer data files from the
CompactFlash card while it is still inserted in the receiver, the Data
Transfer utility converts the raw receiver data (.T01) files you select
into the Trimble DAT file format.
However, if you connect the CompactFlash card to your computer and
then copy or move files to your computer, it treats the card like any
other disk drive, and transfers the files without converting them. You
need to convert these raw receiver files to DAT format files before you
can use them on your office computer.
You can convert receiver data files by using a Windows Explorer
extension which is installed on your computer when you install the
Data Transfer utility.
Note – Although this extension is only available if you have the Data
Transfer utility installed, you do not have to run the Data Transfer
utility to use it.

Introduction
All Trimble R7 receiver settings are stored in application files. The
Default application file, Default.cfg, is stored permanently in the
receiver, and contains the factory default settings for the Trimble R7.
Whenever the receiver is reset to its factory defaults, the current
settings (stored in the Current application file, Current.cfg) are reset to
the values in the Default application file.
You cannot modify the Default application file. However, if there is a
Power Up application file (Power_Up.cfg) in the receiver, the settings
in this file can be applied immediately after the Default application

Logging after power loss
If the Trimble R7 loses power unexpectedly, when power is restored
the receiver tries to return to the state it was in immediately before the
power loss. The receiver does not reset itself to defaults or apply any
Power Up settings. If the receiver was logging when power was lost
unexpectedly, it resumes logging when power is restored.
However, when you switch the receiver off using p, the receiver
behaves as if you pressed d to stop logging before you pressed p.
In this case, when power is restored normally, logging does not begin
until you start it manually.

Application files
You can use application files to change the settings in the receiver.
Sending an application file to the receiver does not necessarily apply
the file’s settings; you can apply a file’s settings at any time after
sending it to the receiver. You can also define timed application files.
A timed application file contains receiver settings, but also includes a
date and time when it is automatically activated.
If there is a timed application file on the Trimble R7, the receiver
automatically applies the file’s settings and begins logging (if logging
settings are included in the file) at the specified time. If the receiver is
in Sleep mode, it wakes up five minutes before the start time of the
timed application file, and then begins logging, if required, at the
specified start time.

Event Marker Input and 1PPS Output
11.1
Introduction
The Trimble R7 receiver can accept event marker input on Port 1 and
Port 2, and can generate 1PPS output on Port 2.
11.2
Event Marker Input
Event marker input is used to log a precise GPS time tag whenever an
externally generated pulse, such as one generated at the time of the
shutter closing from a photogrammetric camera, is received.
The event is triggered when the source pulse voltage transitions
between 1.0 V DC and 2.0 V DC in less than 100 nsec. Trimble
recommends that you use TTL level inputs. You can configure the
receiver to recognize either a positive (rising) or negative (falling)
voltage as the leading edge of a pulse. The accuracy of the associated
time tag recorded for an event is determined by the GPS accuracy
(typically less than 1 µsec.).
The Trimble R7 records each event in the current data file. This record
includes the port on which the event was received.
112.1
Enabling and configuring event marker input
To enable or configure the event marker input function, you need the
GPS Configurator software.
In real time
You can use GPS Configurator to configure a Trimble GPS receiver
connected to your office computer. For more information, see GPS
Configurator Software, page 70, or refer to the GPS Configurator
Help.
To enable event marker input:
1. Connect the computer to the Trimble R7 receiver.
2. Press p to turn on the receiver.

Event Marker Input and 1PPS Output
11.1
1PPS Output
The Trimble R7 receiver can output a one pulse per second (1PPS)
output through Port 2 of the receiver using the event marker/1PPS
cable.
111.1
1PPS pulse definition
The leading edge of the pulse coincides with the beginning of each
UTC second, as shown in Figure 11.1. The pulse is driven by an
RS-422 driver between nominal levels of 0 V and 4 V. The leading
edge is positive, rising from 0 V to 4 V.

Event Marker Input and 1PPS Output 11
The pulse is approximately 8 µsec wide, with rise and fall times of
about 100 nsec. Resolution is approximately 40 nsec, but several
external factors limit accuracy to approximately 1 µsec:
•
Position errors, especially with user-entered reference. Each
meter of error can result in 3 nsec of error in the 1PPS pulse.
•
2 nsec to satellite signals, and a corresponding delay in the
1PPS pulse.
111.2
ASCII time tag definition
Each time tag is output about 0.5 second before the corresponding
pulse, as shown in Figure 11.1. Time tags are in ASCII format on a
user-selected serial port. The format of a time tag is:
UTC yy.mm.dd hh:mm:ss ab
Where:
•
•
•
UTC is fixed text.
yy.mm.dd is the year, month, and date.
hh:mm:ss is the hour (on a 24-hour clock), minute, and second.
The time is in UTC, not GPS time.
•
a is the position-fix type:
1 = 2D Position Fix for E,N only
2 = 3D Position Fix
3 = Single SV Clock-only fix
4 = Automatic Mode
5 = Reference Station Position
6 = Two-Dimensional with Fixed Clock
7 = Overdetermined solution for Clock-only
•
•
b is the number of satellites being tracked: 1 to 9, “:” (for 10),
“;” (for 11), or “<” (for 12).
Each time tag is terminated by a carriage return, line feed
sequence.

UTC 93.12.21 20:21:17 56
UTC 93.12.21 20:21:18 56
If a and b are ??, the time is based on the receiver clock because the
receiver is not tracking satellites. The receiver clock is less accurate
than time readings extracted from satellite signals.
111.3
Enabling and configuring 1PPS output
To enable or configure the 1PPS output function, you need the GPS
Configurator software.
In real time
You can use GPS Configurator to configure a Trimble GPS receiver

Overview
12.3
Use and Care
The Trimble R8 receiver is designed to withstand the rough treatment
that typically occurs in the field. However, the receiver is a
high-precision electronic instrument and should be treated with
reasonable care.
WARNING – Operating or storing the Trimble R8 receiver outside the
specified temperature range can damage it. For more information, see
Chapter 17, Specifications.
C
High-power signals from a nearby radio or radar transmitter can
overwhelm the receiver circuits. This does not harm the instrument,
but it can prevent the receiver electronics from functioning correctly.
Avoid using the receiver within 400 meters of powerful radar,
television, or other transmitters. Low-power transmitters such as those
used in cellphones and two-way radios normally do not interfere with
receiver operations.
For more information, contact your local Trimble distributor.
12.4
COCOM Limits
The U.S. Department of Commerce requires that all exportable GPS
products contain performance limitations so that they cannot be used
in a manner that could threaten the security of the United States. The
following limitations are implemented on the Trimble R8 receiver.
Immediate access to satellite measurements and navigation results is
disabled when the receiver’s velocity is computed to be greater than
1000 knots, or its altitude is computed to be above 18,000 meters. The
receiver continuously resets until the COCOM situation is cleared.

Logging Data
You can log data internally or to a Trimble controller.
145.1
Logging internally
The Trimble R8 receiver logs GPS data internally on 6 MB of internal
memory.
You can then use the Trimble Data Transfer utility to transfer logged
data files to the office computer. The transferred files are in Trimble
DAT (.dat) format.
WARNING – The Trimble R8 allows for a maximum of 200 files on the
internal memory. The filenames must be in 8.3 format, otherwise files
copied to the internal memory may cause data corruption or loss of data
when logging.
C
Data is logged using the current logging settings configured in the
receiver. Data files logged internally are named automatically.
To begin internal logging, you must use a Trimble controller, or the
GPS Configurator utility. The Trimble R8 receiver does not have an
internal clock, so you can only conduct timed survey sessions if the
receiver has a continuous power supply.
When the internal memory is full, the receiver stops logging data, and
the Logging/Memory LED switches off. Existing data files are not
overwritten. You can use the Auto-delete option to override this action
and automatically delete the oldest files when the receiver memory is
full. However, you should use this option with caution because it can
lead to data loss.

– Do not drop or puncture the battery.
– Do not open the battery or short-circuit its contacts.
The Trimble R8 receiver can be powered by its internal battery or by
an external power source connected to Port 1. Typically, one internal
2.0 ampere-hour battery provides approximately 5.5 hours of
operation during an RTK survey using the internal radio in rover mode
and approximately 3.5 hours of operation as an RTK base (this varies
according to temperature and wireless data rate).
If an external power source is connected to Port 1 it is used in
preference to the internal battery. When there is no external power
source connected, or if the external power supply fails, the internal
battery is used.
WARNING – Avoid contact with the rechargeable Lithium-ion battery if it
appears to be leaking. Battery fluid is corrosive, and contact with it can
result in personal injury and/or property damage.
To prevent injury or damage:
– If the battery leaks, avoid contact with the battery fluid.

To protect the battery from deep discharge (5 volts or less), the
Trimble R8 system is designed to switch batteries or cease drawing
power when the battery pack discharges to 5.9 volts.
A battery that has reached the deep discharge level cannot be
recharged and must be replaced. The following recommendations
provide optimal performance and extend the life of your batteries:
•
•
•
Fully charge all new batteries prior to use.
Do not allow the batteries to discharge below 5 volts.
Keep all batteries on continuous charge when not in use.
Batteries may be kept on charge indefinitely without damage to
the receiver or batteries.
•
•
Do not store batteries in the receiver or external charger unless
power is applied.
If you must store the batteries, fully charge them before storing
and then recharge them at least every three months.
Disposing of the rechargeable Lithium-ion battery
Discharge the Lithium-ion battery before disposing of it. When
disposing of the battery, be sure to do so in an environmentally
sensitive manner. Adhere to any local and national regulations
concerning battery disposal or recycling.

Configuration
15.1
Introduction
The Trimble R8 receiver has no controls for changing settings. To
configure the receiver, use external software such as GPS
Configurator, WinFlash, or Trimble Survey Controller.
There are two ways to configure the receiver. You can:
•
•
configure the receiver in real time
apply the settings in an application file
This chapter provides a brief overview of each of these methods and
describes the contents and use of application files.
15.2
Configuring the Receiver in Real Time
GPS Configurator and Trimble Survey Controller support real-time
configuration of the Trimble R8 receiver.
When you configure the receiver in real time, you use one of these
software applications to specify which settings you want to change.
When you apply the changes, the receiver settings change
immediately.
Any changes that you apply to the receiver are reflected in the current
application file, which is always present in the receiver. The current
application file always records the most recent configuration, so if you
apply further changes (either in real time or using an application file)
the current file is updated and there is no record of the changes that
you applied originally.
For more information on configuring the receiver in real time, see
Chapter 16, Software Utilities.
134 Trimble R7/R8 GPS Receiver User Guide

Configuration 15
15.3
An application file contains information for configuring a receiver. To
configure a receiver using an application file, you need to create the
application file, transfer it to the receiver, and then apply the file’s
settings. GPS Configurator does this for you automatically when you
work with configuration files.
For more information on applying application files, see Chapter 16,
Software Utilities.
15.4
Application Files
An application file is organized into records. Each record stores
configuration information for a particular area of receiver operation.
Application files can include the following records:
•
•
•
•
•
•
•
•
•
•
•
File Storage
General Controls
Serial Port Baud/Format
Reference Position
Logging Rate
SV Enable/Disable
Output Message
Antenna
Device Control
Static/Kinematic
Input Message
An application file does not have to contain all of these records. When
you apply an application file, any option that is not included in the
records in the file remains at its current setting. For example, if you

15
Configuration
apply an application file that only specifies the elevation mask to use,
all other settings remain as they were before the application file was
applied.
You can store up to twenty different application files in the receiver.
You can apply an application file’s settings at the time it is transferred
to the receiver, or at any time afterwards.
154.1
Special application files
The Trimble R8 receiver has three special application files, which
control important aspects of the receiver’s configuration.
The default application file (Default.cfg) contains the original receiver
configuration, and cannot be changed. This file configures the receiver
after it is reset. You can reset the receiver by holding down p for at
least 15 seconds, or by using the reset option in GPS Configurator.
For more information on the default receiver settings, see Default
Settings, page 159.
Although you cannot change or delete the default application file, you
can use a power up application file to override any or all of the default
settings.
Current application file
The current application file (Current.cfg) reflects the current receiver
configuration. Whenever you change the receiver’s configuration,
either in real time or by applying an application file, the current file
changes to match the new configuration.
You cannot delete the current file or change it directly, but every
change to the receiver’s current configuration is applied to the current
file as well.
136 Trimble R7/R8 GPS Receiver User Guide
Download from Www.Somanuals.com. All Manuals Search And Download.
Configuration 15
When you switch off the receiver then turn it on again, all the settings
from the current application file are applied, so you do not lose any
changes that you have made. The only exceptions are the following
logging parameters:
•
•
•
Logging rate
Position rate
Elevation mask
These parameters are always reset to the factory default values
whenever the receiver is switched off.
Power Up application file
The power up application file (Power_up.cfg) is used to set the
receiver to a specific configuration any time the unit is powered up.
You can specify that the receiver is reset to defaults before the power
up settings are applied. This ensures that restarting the receiver always
resets it to factory defaults prior to applying the power up application
file.
Alternatively, you can specify that the power up settings are applied
immediately after the current application file’s settings have been
applied. Restarting the receiver results in a configuration that uses
your default settings for the options you define in the power up file,
but the current settings for all other options.
By default, there is no POWER_UP application file on the receiver. To
use a power up application file, you must create and save a
POWER_UP application file in GPS Configurator. If you save this file
to disk, the file is called Power_up.cfg. The extension .cfg is used by
convention to identify application files on the office computer. When
you transfer this file to the receiver, the file is saved on the receiver as
POWER_UP, and becomes the new power up file.
The power up file is the only special application file that you can
overwrite or delete from the receiver.

15
Configuration
154.2
Applying application files
An application file’s settings do not affect the receiver’s configuration
until you apply the application file. You can do this at the same time
that you save the file. Alternatively, you can save the file on the
computer or in the receiver, then open it later and apply its settings.
154.3
Storing application files
You can store application files that you create in GPS Configurator on
the receiver and on the computer. For example, each file can represent
a different user sharing the same receiver, or a particular mode of
operation or survey style. Saving application files on your computer as
well as in your receiver is optional, but it is useful because:
•
•
•
it gives you a permanent copy of the settings you have sent to a
receiver, for audit or your own reference.
you can use the same file to configure multiple receivers
identically.
you can use an existing application file as a template for
creating other application files with similar settings.
154.4
Naming application files
The application filename in the office computer and in the receiver are
always the same. This makes it easier to recognize and keep track of
your application files.
When you change the name of the application file in the receiver, this
changes the application filename on your computer. When you
transfer an application file from the receiver and save it to the
computer, the system renames the file to match the internal receiver
file. However, if you use Windows Explorer, for example, to change
the .cfg filename on the computer, this does not change the internal
receiver filename. This means that the GPS receiver does not
recognize the change to the filename on the computer.

intend to use the receiver, for example, Base with No Repeaters:
4. Select one of the following channel sharing configurations (base
modes only; not available for rover):
–
Off. The carrier detect mode is off. The unit will ignore
other transmissions on your frequency and continue to
transmit data.
Note – It may be illegal in your country of use to set
channel sharing to Off. You may be subject to penalties or
fines based upon the specific licensing requirements for
your country of use. Please consult your radio license
documentation or licensing agency for operational
guidelines.
–
Avoid Weak Signals.The carrier detect mode is on. The
radio will cease transmitting if it detects another radio
transmission on its frequency. It will resume transmission
when the channel is free of radio traffic.

the radio will stop transmitting only when there is a strong
signal present (receive level greater than 90 dBm).
5. If you are operating in Base mode, select the Enable Station ID
check box and then enter your call sign in the Call Sign field.
This FCC requirement is for U.S. licensed users. It sets your
radio to transmit your call sign in Morse code every 15 minutes.
6. To update the configuration, click OK.
In the Status dialog that appears, select an option to return to the
main menu or to exit WinFlash.
Tip – You can print or save the radio configuration information for future
reference. If required, you can fax or e-mail the file to Trimble Support to
aid in troubleshooting radio problems.
B
Updating the frequency list
You can program the internal transceiver modem with a list of up to 20
frequencies, which are stored in non-volatile memory. This list is
pre-configured based on the frequencies that you requested when you
ordered the unit. Government regulations stipulate that only
manufacturers or authorized dealers can create this frequency list and
that all frequencies programmed into a unit must comply with the host
country regulations. If you need to add, delete, or replace frequencies,
contact your Trimble dealer, and provide the radio modem serial
number and an updated list of the frequencies you require. Once you
receive the frequency file, you can upgrade the radio using WinFlash.

Default Settings
18.1
Introduction
All Trimble R8 receiver settings are stored in application files. The
default application file, DEFAULTS is stored permanently in the
receiver, and contains the factory default settings for the receiver.
Whenever the receiver is reset to its factory defaults, the current
settings (stored in the current application file, CURRENT) are reset to
the values in the default application file.
You cannot modify the default application file. However, if there is a
power up application file (POWER_UP) in the receiver, the settings in
this file can be applied immediately after the default application file,
overriding the factory defaults.
For more information about application files, see Application Files,
page 135.

NMEA-0183 Output
A.1
Introduction
This appendix describes the formats of the subset of NMEA-0183
messages that are available for output by the receivers. For a copy of
the NMEA-0183 Standard, visit the National Marine Electronics
Association website at www.nmea.org.
A.2
NMEA-0183 Outputs
When NMEA-0183 output is enabled, a subset of NMEA-0183
messages can be output to external instruments and equipment
connected to the Trimble R7 serial ports. These NMEA-0183
messages let external devices use selected data collected or computed
by the GPS receiver.
All messages conform to the NMEA-0183 Version 3.01 format. All
begin with $ and end with a carriage return and a line feed. Data fields
follow comma (,) delimiters and are variable in length. Null fields still
follow comma (,) delimiters but contain no information.
An asterisk (*) delimiter and checksum value follow the last field of
data contained in an NMEA-0183 message. The checksum is the 8-bit
exclusive OR of all characters in the message, including the commas
between fields, but not including the $ and asterisk delimiters. The
hexadecimal result is converted to two ASCII characters (0–9, A–F).
The most significant character appears first.
Table A.1 summarizes the set of NMEA messages supported by the
Trimble R7 receiver, and shows the page where detailed information
about each message can be found.
