4.2 - Specification of connection to integrator
Cable A: 4 wires connecting cable, used for connection to integrator
Allocation of wire colors:
1 - WHITE: µCom/diagnostic
2 - BLUE: pulse A or diagnostic
3 - BLACK: earth connection (-)
4 - RED: power supply AXONIC (+)
Cable B: 3 wires connecting cable, used for connection to any devices
Allocation of wire colors:
• RED: Pulse B
• BLACK: earth connection (-)
• WHITE: DIR. (Direction of the flow: 1 = normal flow, 0 = backword flow)
