CAMCOLD/CK_v2 2 VELLEMAN
ATTENTION: Please be careful on the sequence of pin wires - colour
• Signal A: Connect all cameras together on connector RS-485-A (connector K2)
• Signal B: Connect all cameras together on connector RS-485-B (connector K2)
• Do not inverse A with B.
• Connect all connections from keyboard connector A with camera connector 1A, camera connector 2A, …
1. Control wires: Connect the RS485 A and B wires from the keyboard to the A and B wires respectively
from the camera, the A and B wires respectively from the port of the scanner head, etc.
2. Terminal resistance: Connect a terminal resistance of 120Ω to the 2 extreme points of the decoder or
scanner head. Other components do not need resistance.
3. Matching resistance of 120Ω: Wires or ON/OFF switches are on the keyboard. Jumper K4 in the
keyboard is for the matching resistance. When switched to ON, the resistance is connected to the
extremity; otherwise, on effect.
1. Connecting 1 dome camera (with PELCO-D protocol)
1. Connect controller signal A to camera signal A.
2. Connect controller signal B to camera signal B.
3. Establish the camera address as address 1 (00000001) see 4.1
4. Establish the camera protocol (standard protocol is PELCO-D protocol). Usually, you do not need to change
the protocol because the controller uses the Pelco-D protocol.
See 4.1 to change the protocol.
You can also modify the protocol by using the “F4” button on the controller.
4.1 How to set up the PELCO-D protocol
On the camera (bottom of the camera) there is a DIP switch enabling you to adjust the address and the
protocol of the camera. The first six switches are for the address (from 1 to 63). It is possible to connect 64
cameras. The last 2 switches serve to set up the protocol.
12345678 = DIP switch nr.
Address 1 => 00000001 Characters in bold and italic: Pelco-D protocol
Address 2 => 10000001 78
Address 3 => 01000001 01
Address 4 => 11000001
Address 5 => 00100001
Address 6 => 10100001
Address 7 => 01100001
Address 8 => 11100001
Address 9 => 00010001
Address 10 => 10010001
Etc.….
‘1’ in the table means the switch is ON; ‘0’ in the table means the switch is OFF.
4.2 How to set up the PELCO-P protocol
12345678 = DIP switch nr.
Address 1 => 00000010 Characters in bold and italic: Pelco-P protocol
Address 2 => 10000010 78
Address 3 => 01000010 10
Address 4 => 11000010
Address 5 => 00100010
