SeaI/O User Manual
Configuring an Ethernet Module (Continued)
NOTE:
If the module does not change or respond, the PC and the module
may be on different subnets. Proceed to the Recover Module
section on the following page.
Start MaxSSD (Start Æ All Programs Æ Sealevel SeaMAX Æ MaxSSD) and choose
the correct IP address to communicate with the “base” Ethernet SeaI/O module.
Ensure a successful Get operation (refer to the MaxSSD section on the following
pages for more information).
Set the slave ID of the “base” Ethernet SeaI/O module using the rotary switch or
software selection method discussed in the Setting Device Address section on the
previous pages. This guarantees that any expansion modules connected next will not
conflict with the “base” module. Perform another Get operation to verify that you
can communicate with the “base” Ethernet SeaI/O module at the new slave ID.
NOTE:
Configure the SeaI/O modules one at a time. Set the address to a
hardware slave ID other than “0” or a software slave ID other than
247, which avoids device conflicts during setup.
After the “base” Ethernet SeaI/O module is successfully communicating via
MaxSSD, you can proceed with adding SeaI/O expansion modules (N-series). Refer
to the Configuring Expansion Modules section on the previous pages.
