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
