Thanks dude for you reply..
I did set on CAM 1 thats on CU-161, have set coax on CU-161. Where can i find the camera setup button? what i came across is the SW1 and SW2 which i tried to put off all as you stated. I got the camera menu while holding the setup button on CU-161 controller and manage to get all the menu including the Communication menu.
While restarting the camera i can see the camera menu which stays for only few seconds and it disappear.
I really dont know what could be the problem here, i will be very thankful if i can get a help support and know the problem.
Thanks
Nash
