Quick-Start Guide
1 Prior to installing the wireless link, verify proper operation of PTZ
controller (keyboard) and hard-wired receiver/driver or dome.
2 Determine the bit rate and interface (RS232 or RS485/422) of the
hard-wired system. If it is not 9600 bps and RS485/422, you will need
either to change the setting of the PTZ controller and receiver/driver
or to change the settings of the PTZ-900 equipment. See the end of
this manual for information on changing PTZ-900 internal settings
using TrangoLink software.

Install antennas above the enclosures and position as shown on page 3.
Important! The PTZ-900TX (transmitter) uses a special antenna con-
nector. Use only the AD900-9-P or the AO900-3-P antenna, otherwise
damage to the unit may occur.
Use extreme care when installing antennas near power lines. You
can be killed if the antenna comes in contact with the power line.
.
Do not apply power to the transmitter unless the antenna is con-
nected. Permanent damage to the unit may result.
7 Fasten the antenna cables to receiver and transmitter only finger-
tight (no more than 8 lb/in. of torque). Tighten flange around cables.
Apply a small amount of silicone to the flange openings to make a
leakproof connection.
The PTZ-900TX transmitter’s effective radiated output varies
between 0.5 and 4 watts, depending on the transmit antenna
used. Although transmissions are of a short duration, it is rec-

This equipment generates, uses, and can radiate radio-frequency en-
ergy and, if not installed and used in accordance with these instruc-
tions, may cause harmful interference to radio communications. How-
ever, there is no guarantee that interference will not occur in a particu-
lar installation. If this equipment does cause harmful interference to
radio or television reception (which can be determined by turning the
equipment off and on) the user is encouraged to correct the interfer-
ence by one of more of the following measures:

System Description
The PTZ-900 is a professional-quality wireless transmission system
designed for sending digital, simplex (one-way) signals for pan, tilt,
zoom and camera control up to twelve miles in line-of-sight. The sys-
tem employs 900MHz frequency-hopping spread-spectrum technology
with the maximum effective radiated output power allowed by the FCC
for unlicensed operation. The system will operate interference-free with
the Trango Falcon or Eagle series wireless video transmission systems
to form a complete, wireless control link.
1 Reorient the receiving antenna;
2 Separate the affected equipment from the receiver;
3 Connect the affected equipment to an outlet on a different circuit
from that which the receiver is connected to;

Make sure that you have tested the PTZ controller and receiver/driver/
dome using a direct connection (with wires) before installing the wire-
less link. Also, it is recommended that the wireless link be tested at
short range before installing permanently. The transmitter and receiver
units may get warm to the touch. This is normal and does not affect
operation in any way.
be securely mounted into the ground or to a structure to prevent move-
ment of the antenna and camera in windy conditions. This pole also
acts as an earth ground and must be grounded.
Point-to-Multipoint Operation
In some cases it may be necessary to control more than one camera
from the same console. In this case, one PTZ-900TX transmitter can be
used to send control signals to all receivers and the receiver/drivers
will filter the data as in a hard-wired system. The user must ensure that
all PTZ-900RX receivers have the same address and hopping sequence
as the transmitter. Mount any antenna receiving from an AO900-3-P
omnidirectional in the vertically polarized position.
The PTZ-900 system is factory-configured for operation at 9600 bps,
RS-485/422 mode, hopping sequence 0, address 0000. If your PTZ con-
troller and dome operate at a speed other than 9600 bps or use RS-232
protocol, you must reprogram the PTZ-900TX and PTZ-900RX using the
supplied programming cable and the TrangoLink software, which runs
on any computer with Windows 95 or higher. See page 11 for detailed
information.

of a building is typical. Make sure that the mast is well grounded to
earth ground with a wire of AWG 8 or greater. For distances more
than eight miles, the transmit and receive antennas must be fifteen
to twenty feet above all obstacles in the line of sight.

3 Do not add additional lengths of cable to connect the receiver to the
antenna, as significant losses in signal and reduced transmission
range will occur.
Multilink Operation
4 Keep the data link (shielded twisted-pair) cables as short as possible
to prevent distortion of the data and possible interference with video
running on coaxial cable nearby.
Different than point-to-multipoint operation. multilink is where more
than one transmitter is operating in the same area. In this case, all the
transmitters and receivers operating on one system would have the
same hopping sequence and address. Those on another system nearby
should have a different address and a different hopping sequence in
order to add more isolation between the systems
The PTZ-900 system transmitter and receiver units come pre-mounted
in a NEMA 4× aluminum enclosure. This permits the unit to be mounted
outdoors.

transmitter antenna. The antennas authorized for use with this unit are
the AD900-9-P patch and the AO900-3-P omni. The maximum transmis-
sion range when using the omni will be reduced by approximately half.
The connector used is custom and is somewhat fragile. Fasten the con-
nector only finger-tight, no more than 8 lb/in. Important! The trans-

give the best results in general.
9 Raise transmitter and receiver antennas above ground and away from
obstacles and traffic, including foot traffic.
After entering the program, a screen is displayed showing the current
settings. The user may change the settings and then must click SAVE
CHANGES AND EXIT. Upon exiting the program and cycling power to the unit,
the settings will become effective. This screen offers the user five options.
9 Verify that all connectors are tight, especially the power connectors.
9 Shorten the receiver antenna feed cable. It is best to use only those
cables supplied with the equipment.
PN Sequence. The channel-hopping sequence must be the same on the
transmitter and receiver in order for data to be transferred properly.
RSSI. The Received Signal Strength Indicator is used for receiver to
monitor the radio spectrum on all hopping channels. It is presented as
a bar graph of power (dBm) against frequency (MHz). Useful in trouble-
shooting to determine if any other signals are present in the 900MHz
band. Meaningless if connected to the PTZ-900TX.
9 If the system becomes unusable for a period of time on the order of
minutes or hours and then becomes usable again, changing the PN
sequence may cure the problem. The different PN sequences have dif-
ferent waiting channels that are used to synchronize the hopping se-
quences. Depending on your environment, there may be a 900MHz
transmitter interfering on one of the waiting channels. By changing
the PN sequence of the transmitter and receiver, the waiting chan-
nel will change. Some of the types of equipment that may interfere
are 900MHz cordless phones and wireless LANs if they are very close
to the PTZ-900RX receiver antenna. The waiting channels are
924.2MHZ (default) PN0, 905.8MHz PN3, 911.8MHz PN2, and
918.2MHz PN1.
Data Rate. The rate for PTZ data can be set between 1200 and 19200
bps. Parity can be set to odd, even, or none. The settings must be the
same on the transmitter and receiver.
Mode. RS-232 (unbalanced) or RS-485/RS-422 (differential). Select the
mode that matches your PTZ control equipment.
9 High-power equipment operating near the 902–928MHz band, such
as paging system base stations or cellular phone base stations, may
also interfere if they are within several hundred feet of the receiver.
Changing the PN sequence and reorienting the receiver antenna will
most likely cure this type of interference.
Address. Multiple systems deployed in the same area should have dif
-
ferent addresses. Similar to PN Sequence, the address setting must be the
same on the transmitter and receiver in order for data to be transferred
properly. You must click on SET ADDRESS to make changes effective
9 The cable from transmitter to PTZ controller may be too long, cor-
rupting digital data. Use category 5 twisted-pair shielded cable, if
possible, and a maximum length of four thousand feet for RS422 or
one hundred feet for RS232.
Troubleshooting
Interference or intermittent operation.
9 The cable from receiver to PTZ receiver/driver may be too long, cor-
rupting digital data. Use category 5 twisted-pair shielded cable, if
possible, and a maximum length of four thousand feet for RS422 or
one hundred feet for RS232.
9 Heavy equipment such as industrial, roof-mounted air conditioners
or fan motors in close proximity to the transmitter, receiver, or cables
may cause interference, especially when operating in RS232 mode.
Move the unit/cable away from the source of the interference.
9 Interference on video signal when sending PTZ data. Check the
system’s grounding and use ground-fault isolation transformers if
the problem persists.
