The communication cable (750-920) is connected to the 4-pole header.
3.1.2.6 Hardware Address (MAC ID)
The DIP switch is used both for parametrizing (setting the baud rate) of the fieldbus Coupler and for setting the MAC ID.
The MAC-ID (node address) is set with the DIP switches 1 to 6 by 'sliding' the desired DIP switch to 'ON'.
The binary significance of the individual DIP switches increases according to the switch number. DIP switch 1 being the lowest bit with the value 20 and switch 6 the highest bit with the value 25. Therefore the MAC ID 1 is set with DIP1 = ON, the MAC ID 8 with DIP4 = ON, etc.
For the DeviceNet fieldbus nodes, the node address can be set within the range from 0 to 63.

The configuration is only read during the power up sequence. Changing the switch position during operation does not change the configuration of the buscoupler. Turn off and on the power supply for the fieldbus coupler to accept the DIP switch change.
The default setting is MAC ID 1.
