SeaI/O User Manual
Configuring the “Base” SeaI/O Module
After you have decided which address (slave ID) method you intend to use, proceed
with installing the SeaMAX Software Suite (discussed in the following section).
Once SeaMAX has been installed successfully, start by connecting the E-, U-, M-, or
S-series module to your computer. This module will be referred to as the “base”
module.
If you are chaining multiple SeaI/O modules together, only one SeaI/O module in the
chain can be the “base”. All other SeaI/O modules connected to the “base” module
are referred to as expansion modules. Multiple “base” modules can be directly
connected to a host computer, but expansion modules must be connected (daisy
chained) to a “base” module.
NOTE:
If you are configuring an Ethernet SeaI/O (E-series) module, skip
ahead to the Configuring an Ethernet Module section for
additional information on installing an Ethernet module.
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 Æ All Programs Æ Sealevel SeaMAX Æ MaxSSD) and choose
the correct port (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 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” 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” module is successfully communicating via MaxSSD, you can
proceed with adding SeaI/O expansion modules (N-series), as required.
NOTE:
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.
