Hard reset being too hard to figure out...

[daendy 0]

Hey everyone,

 

I recently got ahold of a DVR and camera but for the life of me I can't figure out how to reset it (the camera)

It's an old 15-CD53 and I was able to communicate with it thru rs485 but I can only steer it left/right/down/up no zoom/iris/preset is working and

that's why I can't use OSD menu to reset it.

 

 

I tried everything, some guides suggested to short pins and I did short the M pins for 30sec, 1min and nothing happens.

Any bit of help is apprieciated
