Maximizing Performance
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 items can be purchased from our website (
) or by calling our sales team at +1
(864) 843-4343.
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.
