SeaI/O Manual 49
Following these simple steps can eliminate most common problems.
1. Read this manual thoroughly before attempting to install the device in your system.
2. Uninstall any previous versions of the SeaMAX software before installing any new
versions.
3. Install SeaMAX software before connecting any Sealevel I/O devices. Installing
the software places the necessary files in the proper locations on your system. After
installing the software, proceed with adding the hardware.
4. When installing SeaI/O modules, connect them one at a time. The “base” module
must be properly configured and communicating successfully with the host before
you can add additional expansion modules. Verify that each expansion module can
communicate before connecting additional expansion modules.
5. Confirm that all screw terminal connections are correct and secure and that the
correct cables are being used, including network cables (crossover vs. patch cables).
6. You can use standard network patch cables (straight-through cables) to connect
SeaI/O modules together via the pass-through connectors on the left side of the
module. Crossover cables should never be used to connect two or more SeaI/O
modules together. Crossover cables should only be used to connect an Ethernet
SeaI/O module to a host without going through an Ethernet hub or switch.
7. On SeaI/O modules, verify that the device address (slave ID) is properly set. Refer to
the Hardware Configuration section of this manual for instructions on setting the
device slave ID.
8. Use the MaxSSD utility, included on the software CD, to verify proper installation.
MaxSSD is designed to simplify the installation, configuration, and diagnostics of
Sealevel SeaI/O modules.
9. If the SeaI/O modules only sometimes respond to a Get operation or return invalid
data, you may have termination improperly set. Refer to the Hardware Configuration
section of this manual for instructions on properly setting line termination and pull-
up/pull-down resistors.
10. Refer to the Troubleshooting Ethernet & Wireless Modules section on the following
page for additional steps regarding Ethernet (E-series) SeaI/O modules.
