SeaI/O Manual 11
All SeaI/O modules have a default baud rate of 9600. If lower latencies are required, the baud rate
can be changed via the Sealevel utility, MaxSSD, included in your SeaMAX installation.
All modules, including expansion modules, must have the same baud rate or
communications errors will occur.
To change the baud rate, connect to a SeaI/O module using MaxSSD. If you need to change the
baud rate of multiple devices, check the “Broadcast to Multiple Modules” box. Select the desired
baud rate from the baud rate dropdown, and click “Set Settings.” If you are connected to the
modules via a COM port, you will need to reopen the COM port with the new baud rate.

Higher baud rates are more susceptible to electrical line noise. If you find that you are
receiving erroneous results, try lowering the baud rate or shortening your cables.
