Introduction
Overall Description
The SMP Software along with the QSB-1 and FM-1 allow a
user to easily manage large systems of BTR-1 base stations
along with their beltpacks.
The QSB-1 (Qard Serial Bus) pod interfaces with the SMP via
a USB connection to the computer. This enables the user to
download events into a small, convenient, DataFlash® card.
FM-1 "Snap Shots" can also be uploaded to the SMP from the
DataFlash® card via the QSB-1.
The SMP (System Manager Program) software enables a user
to set-up multiple events on the computer. An event is a partic-
ular situation where a pack of ten base stations need their pa-
rameter set a certain way. These parameters include transmit
and receive frequencies, intercom levels, auxiliary levels, to
name a few. The event could be a football game or act one of a
broadway show, the possible applications are endless. A good
example is a college football team which uses a ten pack
BTR-1 system for its’ coaches on the field to talk to each other
and the personal in the press box. If that team plays twelve
games a year and six of them are away then the SMP could be
used to set up 7 events. Event one would be the frequencies
and parameters for a ten pack of base stations used at home.
The other six events would be the ten pack’s frequencies and
parameters for the away locations.
The FM-1 (Frequency Manager) interfaces with up to ten
BTR-1 base stations. The FM-1 talks to the bases via a CAN
bus system. The CAN bus starts at the FM-1 and daisy chains
through all the base stations and then back to the FM-1 to ter-
minate. The DataFlash® card is inserted in the card reader
slot for the FM-1 to read events from the card. With the
DataFlash® card in the FM-1 the user can select an event on
the card and download the selected event. Now the user can
download the event into the base stations. The FM-1 can also
take “snap shots”of the ten pack of bases and download those
parameters on the DataFlash® card for eventually uploading
into the SMP.

rows in Excel can be base TX frequen-
cies and the 2nd column of 10 rows can
be the RX frequencies. This 2 x 10 array
of numbers is then selected and copied to
the clip board. Now "Paste Frequencies"
may be used to paste the 2 x 10 array of

The input to the FM-1 is a standard IEC connector. It accepts
100 – 240 VAC, 50 – 60 Hz.
If the unit has been connected to AC power for some time, and
the front panel switch is turned on, the unit will power-up al-
most instantaneously. However, if the unit has its’ power
switch in the on position and is then powered by VAC voltage
via the rear panel the unit will take 3 to 4 seconds to
power-up. This is normal, the internal power supply of the
FM-1 takes 3 to 4 second to power up if powered-up cold.

Operation
Basic Description
The FM-1 (Frequency Manager) interfaces with up to ten
BTR-1 base stations. The FM-1 talks to the bases via a CAN
bus system. The CAN bus starts at the FM-1 and daisy chains
through all the base stations and then back to the FM-1 to ter-
minate. The flash card is inserted in the card reader slot for the
FM-1 to read events from the card. With the flash card in the
FM-1 the user can select an event on the card and download
the selected event. Now the user can download the event into
the base stations. The FM-1 can also take “snap shots” of the
ten pack of bases and download those parameters on the flash
card for eventually uploading into the SMP.
The lower left-hand corner contains the software version in
the FM-1. After the start-up screen the event screen will be
displayed. The event screen is the main default screen. It will
display the current event in FM-1 memory. Up to 99 events
may be stored in the FM-1 and on a card, see the "FM-1 Menu
Flow Chart section for the menu structure.
Connecting the FM-1 to the Base Stations
The FM-1 communicates to the base stations via the CAN bus.
This CAN bus starts at the FM-1 “OUT” port. It is connected
from there to the first base station. It does not matter which
CAN bus base station jack is the input or output. From the
first base it daisy chains through all the base stations (up to
ten). The CAN bus connects from the last base station to the
FM-1 port marked “Termination”.

Downloading a Card
The following steps download a card to the FM-1.
After programming the display will indicate the following:
1. From the event screen press <MENU> once to arrive at
the download card / select event menu screen.
Normal Numbers = The BTR-1 were programmed to the
parameters downloaded.
2. Select download card with the <UP>/<DOWN> arrow
buttons and press <SET> to go to the download screen.
Inverted Numbers = Programming of the base cannot be
confirmed.
3.
Make sure the DataFlash® card is in the FM-1 and
press <SET>. The unit will indicate it is downloading
from the card.
Snap Shot
The FM-1 can take snap shots of the base station connected to
its’ CAN bus. This is a record of the base station’s frequencies
and settings at the time the snap shot is taken.
4. The FM-1 will say it has completed the download. Af-
ter a few seconds it will now go to the event screen.
The <MENU> button could also be pressed to proceed
to the event screen.
1. From the event screen press <Snap Shot> for about 2
seconds. The following screen will occur. Make sure
there is a DataFlash® in the FM-1.
The contents on the DataFlash® card write over all previous
FM-1 memory.
Selecting an Event and Downloading to
System
The following steps select an event that has been downloaded
from a DataFlash® card to the FM-1. Then that event is
downloaded to the BTR-1s on the CAN bus.
2.
Press <SET> to take the snap shot.
1. From the event screen press <MENU> once to arrive at
the download card / select event menu screen.
A snap shot is saved to the DataFlash® card. If the snap shot
is successful, the confirmation screen displays, then defaults to
the event screen.
2. Select “select event” with the <UP>/<DOWN> arrow
keys and press <SET> to go to the select event screen.
3. The last event in FM-1 memory will be displayed.
Press <SET> and the current events in memory will be
displayed. The event will begin flashing.
Up to 10 snap shots may be placed on a DataFlash® card.
4. Use the <UP>/<DOWN> arrows to select the event de-
sired. Press <SET> at the displayed event to enter the
system download screen.
5. Press <SET> again at the above screen to send the
event to the system of BTR-1 base stations.
6. After programmed, press <MENU> to arrive back at
the event screen.
As the BTR-1s are programmed and confirmed the numbers
displayed will blink and turn to normal characters to show
programming did occur.

Bands F to E are always base transmit bands (beltpack receive
bands). Bands 1-7 are always base receive bands (beltpack
transmit bands). Thus an A2 base station would be comprised
of an A band transmitter paired with a 2 band receiver.
Band Pairing for Systems
All band pairs cannot be made into a system (a single system
is comprised of a base and beltpack). Table 1 show the avail-
able band pairings.

Available Band Pairings
In Table 1 it can been seen that a C base station transmit band
can be paired with 4, 5, 6 or 7 receive bands. However, a C3
unit cannot be made. This is because a certain amount of fre-
quency separation between transmit and receive bands is re-
quired for good transmit and receive operation. If they are too
close the RF performance of the system is reduced.
