Set the Node Address on the Base Module

The node address for network connection is set using two 8-bit DIP switches.

To set the node address, lift the door containing the status LEDs on the top

left side of the module. The switches are read at module power up only. The

rack address setting and the starting quarter setting are described below.

IMPORTANT

It is important to monitor the rack fault bit. When

installing a system for the first time, it is possible to

mistakenly put devices with duplicate rack addresses

on the same network. Blocks with duplicate addresses

may in certain instances cause outputs to toggle on/off

until the duplicate address error is corrected.
