Why can't I control the dome camera using the GE Keypad?
If you're unable to control the dome camera, verify that the voltage along the RS-422 data line reads approximately 1.5 VDC and drops when a command is sent. Also, check the power line and verify that the resistance across the RS-422 data line is between 95 and 125 ohms. The cause of the problem might be poor voltage or resistance on the data line.
What to do if I can’t control cameras or DMVRes with my GE Keypad?
If you're having trouble controlling cameras or DVMRes, first ensure you are in zone mode. Then, try cycling the power on the DVMRe and keypad. Check the wiring, making sure you're using the correct type of wiring (STP or UTP) for the signals, that all wires are in good condition, cabling and pinout connections are correctly made, equipment is properly terminated, and cables are properly grounded. The issue might be due to incorrect wiring of dome inputs or incorrect zone addressing, so try readdressing the cameras or moving the coaxial connections up one input on the DVMRe.
What to do if I cannot connect to a DVMRe using GE KTD-405?
If you're unable to connect to a DVMRe, ensure that the correct hub device is selected in the zone programming menus, as the selection defaults to Triplex. Additionally, check the termination and bias settings.
Why is the audio unclear on my GE KTD-405A Keypad?
If the audio on your KTD-405A keypad is unclear, make sure that the attenuation jumpers are correctly set. Also, if a KTD-336 is present, ensure that its relays are not clicking.
How to restore control between GE keypads connected using RS-422?
To restore control between keypads connected using RS-422, refer to the keypad, switcher, and data merger installation instructions and correct the wiring along the RS-422 control line. With the KTD-405 keypad, the units should be in line in the following order: keypad, data merger, and switcher.
