Configuring N-Series Expansion Modules
Once you have successfully connected and communicated with a “base” module, you
can begin adding expansion modules (N-series). Connect a single expansion module
to the “base” module via the RJ45 pass-through connectors or screw terminals on the
left side of the enclosure. Expansion modules include a convenient 5” interconnect
cable (item# CA239) to simplify daisy-chaining SeaI/O modules together.
Alternately, you can use standard network patch cables to chain expansion modules
to a “base” module.
NOTE: The RJ45 pass-through connectors are NOT Ethernet connectors.
Do not connect the ports to Ethernet enabled devices else damage to
Ethernet devices
WILL result.
Ensure a successful Get operation (refer to the MaxSSD section on the following
pages for more information). Set the slave ID of the expansion module using the
rotary switch or software selection method discussed in the Setting Device Address
section on the preceding pages. Perform another Get operation to verify that you can
communicate with the expansion module at the new slave ID.
Continue adding expansion modules (N-series), one at a time, until all modules have
been successfully daisy-chained together and respond to a Get operation in MaxSSD.
Once all SeaI/O modules are configured and communicating successfully, they are
ready to communicate with your application.
