Set the Network Type and Node Address Switches
Before you install the module, you must set the network type switches for
each channel. If the network type is Data Highway Plus (DH+), you must also
set the node address switches for that channel to a unique address within the
range of 00-77.
IMPORTANT If your module uses the 230k DH+ network, that is, Channel A switch set to 3,
Channel B is disabled.
Also, node address switches do not apply if you are using remote I/O.
