If you are configuring an Ethernet (E-series) or Wireless (W-series) SeaI/O module, skip ahead to the
Configuring an Ethernet Module or Configuring a Wireless Module sections for specific information on
installing those modules.
For all other SeaI/O modules (U-series, S-series, or M-
series), locate the COM port by expanding the ‘Ports’ list
in Windows Device Manager.
Start MaxSSD (Start
→
All Programs
→
Sealevel SeaMAX
→
MaxSSD) and choose the correct
po
rt (IP address or COM port) to communicate with the “base” 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” module using the rotary switch or software selec
tion 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 t
he “base” module at the new
slave ID.
Configure 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” module is successfully communicating via MaxSSD, you can proceed with adding
SeaI/O expansion modules (N-series) one at a time as required.
If the “base” module doesn’t respond as expected, turn the rotary switch (ADDR) clockwise one full
revolution to reset. Configure the PC to communicate at 9600 bps and no parity and then try again.
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 (Part# CA239) to simplify d
aisy-chaining SeaI/O modules together.
Alternatively, you can use standard network patch cables to chain expansion modules to a “base” module.
The RJ45 pass-through connectors on the left side of SeaI/O modules 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.
