rev E Trango Systems, Inc. 76 PTZ-900 Installation and Operating Instructions
Installation
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.
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-900
TX 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.
To obtain the best performance and transmission distance, the follow-
ing rules of thumb should be followed:
1 Mount the transmitter and receiver antennas above human and me-
chanical traffic, the higher the better. A ten-foot steel mast on top
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.
2 Keep the transmission path as open as possible. Objects such as walls
and metallic objects near the transmission path may reduce the
transmission distance.
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.
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.
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.

Important! The PTZ-900 enclosures are designed for a steel pole with
a maximum diameter of 2
3
/
8
″ and a wall thickness of ¼″. The pole must
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-900
TX 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-900
RX 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.
Multilink Operation
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
