The communication cable (750-920) is connected to the 4 pole header.
Warning
The communication cable 750-920 must not be connected or disconnected
while the coupler/controller is powered on!
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 2
0
and
switch 6 the highest bit with the value 2
5
. 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 bus-
coupler. Turn off and on the power supply for the fieldbus coupler to accept
the DIP switch change.
The default setting is MAC ID 1.
