Symptom: No video from interface.
Possible causes:
1. Camera is not powered or not connected to 'CAMERA' BNC on interface.
Check power and cabling.
2. Interface is not powered.
Check power.
3. Video out not connected to 'TELEMETRY' BNC on interface.
Check cabling.
If the after following the above check list video still not present then remove both BNCs from the
interface and connect together using a female/female barrel connector to check video path from
camera to control point.
Symptom: No camera control but lights relay operates with LIGHTS key on transmitter.
Possible causes:
1. Dome data cable is not connected correctly.
Check cabling, most commonly due to data cables swapped.
2. Dome configuration switches if fitted not set correctly.
Check configuration.
Symptom: No camera control and lights relay not operating.
Possible causes:
1. Interface not seeing Telemetry signal.
Check that telemetry is present on video cable using either oscilloscope or adjust v.hold on
monitor to view frame blanking period and check for black/white band. If missing, power
down/up the transmitter. Should this fail, swap video between working and non working
channels.
2. Earth loops can interrupt telemetry operation if sufficiently severe.
If hum bars are apparent, fit isolation transformer to coaxial cable.
3. Check cable and error LEDs on interface.
See SETUP section earlier in this manual for correct indication.
