Channel Vision P-0328 manual Troubleshooting

Troubleshooting

If your IR system is not working, check to see if the P-0328 is feeding approximately 12 Volts DC onto the coax between the shield and center pin. (Any voltage between 8-12VDC is OK). If there is no voltage between the center pin and shield, check the connectors on each end of the coax to make sure there are no shorts (no shielding touching the center conductor).

If you are using an RF splitter between the modulator and the P-0328 or between the P-0328 and the IR coax adaptor (IR-4101), check to make sure you have approximately 8-12 Volts DC on the coax going into the IR-4101. If there is no voltage at that point, check the following items:

1.If you are using a splitter on the TV outputs of the P-0328, make sure it is DC passing. Traditional splitters will short out DC voltage traveling on the coax and prevent your IR system from working.

2.If you are using a splitter on the TV outputs of the P-0328, make sure that there are DC blocks (model 3109) on any output from the RF splitter that will not be connected to an IR-4101. If outputs from the splitter are connected directly to TV sets without going through an IR-4101 or DC block, the system voltage will be shorted out by the input of the TV set.

3.Double check the fittings at the end of your coax cables. If a little bit of shielding is touching the center pin, the voltage will be shorted out and the system will not work.

4.Don’t worry. There are 8 IR engines in the P-0328 one for each TV output. The IR engines have a current limiting circuit. If an engine is shorted (due to a bad connection or a non-DC passing splitter) nothing will be harmed.
