ZR-DC/WBX
Installation and Operating Instructions
CONNECTING THE TELEMETRY
You can use either coaxial or twisted pair telemetry with your ZR-DC/WBX. It switches automatically to the type of telemetry
it first receives after the power is applied.
Twisted-pair Telemetry
Connect Baxall 20 mA twisted pair telemetry to CON 3 on the main PCB. Either polarity is accepted.
Coaxial Telemetry
Baxall coaxial telemetry is connected as the video connections are made. Note that you can still connect the video through
the PCB if you use twisted-pair telemetry.
CONNECTING THE VIDEO
Connect all video using 75 ohm video coaxial cable terminated by BNC connectors. Connect the camera to VIDEO IN, and
the transmitter to VIDEO OUT.
Note
: In order for the auto pan and preset tour functions to operate correctly, the video from the camera must be routed
through the receiver PCB.
CONNECTING THE ALARM INPUTS
Your ZR-DC/WBX has 8 alarm inputs. The alarm inputs are split into two banks. Alarm inputs 1 to 4 are always configured
as normally open (N/O). Alarm inputs 5 to 8 are configured as normally open unless the select terminal (SEL) is
connected to ground. In this case they become normally closed (N/C).
Note: When AL5 to AL8 are configured as normally closed, any unused alarm inputs must be connected to ground to
ensure correct operation.
CONNECTING THE ALARM OUTPUT RELAY
A normally open, volt-free relay contact is provided for alarm output purposes. This relay contact closes for approximately
one second for each new alarm condition. The relay is rated for a maximum of 3A at 240V AC.
