OK, I think I've sorted the make and model no. from some info within the cam body, it turns out to be a Lilen PIH-6725PF, however I still cannot get it to function using the settings described in their instructions. It would appear as if to set the protocol to Pelco D or P you have to have the 4 setting switch as on-on-off-off, for Pelco P and the address of ID 01 as on-off-off-off-off-off-off-off on the 8. Umm I've set my AVTECH to protocol = Pelco P and used the address 1 for the cam ID... switched all off and back on to reset and initialise the PTZ Cam, do I have to do the same to the avtech recorder ? still no movement, I've swopped the 485 +/- wires... no resolve.
Any thoughts folks ??
