Hi Group Have just joined this forum and hope you can help me please. I just bought a Remote Control Tilt Camera. Its called a mini pan/tilt dome camera,model No D501 if this helps. Anyway the instuction manual is very poor to understand. The dome has the usual leads,but there are four coloured wires red/blue/green/yellow. This is to connect to the RS-485 Reciever box. This is the problem,which wire goes where to the reciever box. There are 5 connectors from left power socket. Also there is 8 dip switches on the dome Hope somebody here may have the same camera,or could somebody here help me out Many thanks Ray
