PTZ Connection
Telemetry stations are used for the control of cameras with Pan/Tilt/Zoom (PTZ) hardware. They
are connected to the ADPRO FastTx and can be controlled by commands issued via the PTZ
port connector.
ADPRO FastTx supports a number of PTZ telemetry station models
provided
all of the PTZ units
are the same model. Communications with the telemetry stations utilises RS485 ‘multi-drop’
signalling via the ‘PTZ’ port on the rear of the chassis.
ADPRO FastTx supports ‘Down the Coax’ telemetry. A ‘Down the Coax’ telemetry module must
be installed in the ADPRO FastTx if this functionality is required. Please contact your service
centre if this option is required.
A single 9 way D connector is provided on the unit to support RS422 and RS485 connectivity to
PTZ camera stations. The connectivity is shown below. To change between RS422 and RS485,
use DIP switch 5 on the rear of the unit. To provide termination of the RS485 line use DIP switch
8 on the rear of the unit.
