6. Complete the install If there’s a problem at this stage...
7. Verify basic operation
1a - wall bracket option. After making all the
connections to the PCB, fit the junction box
cover with the four screws.
…work through the logical steps below to determine and rectify the problem
No picture - check the PCB to make sure the red power LED is lit. If not, check that the PSU is
correctly connected and has power. If you have a test meter, verify that the output of the PSU is
approximately 24V AC.
If the power LED is lit, check the BNC crimp connection is correctly made at both the PCB end and
the DVR / monitor / matrix end. A portable test monitor connected directly to the video output of the
speed dome is also a useful test - if a picture is displayed, double check the BNC connections and
the signal cable used.
No PTZ control - check that the control equipment you are using is compatible with the speed
dome and is configured to match the speed dome settings correctly.
If dip switches were changed on the speed dome, check the power on self test screen to ensure
that protocol, ID and baud rate are as expected.
If the settings match, you should check the polarity of the connections, both on the control
equipment and the speed dome. If you suspect there is a polarity issue, swap the A & B wires at the
speed dome to see if this resolves the problem.
Check also that there are no other telemetry devices on the system with the same ID as the speed
dome. If in doubt, connect the speed dome directly to the PTZ controller and isolate all other
equipment.
1. After carefully checking the installation,
including all cable connections, apply power to
the dome and check that the startup and self
test screen is displayed. 2. After the self test is complete, the dome
starts normal operation. Verify that there is
basic PTZ control from your control equipment.
Note: when fixing the cover to the junction box, ensure that the seal is also
fitted properly and that none of the cables are trapped
1b - pendent option. After making all the
connections to the PCB, raise the dome
assembly to the junction box, connect the
dome cable to the PCB and fix with the four
screws.
