Digital I/O Tab 
The “Digital IO” tab of MaxSSD is displayed when using Sealevel I/O devices 
featuring discrete inputs and outputs. It displays the device’s current input and/or 
output status in an intuitive and usable manner. 
When displaying SeaI/O or SeaDAC modules (excluding SeaDAC Lite), the “Digital 
IO” tab displays inputs and outputs in groupings (or banks) of eight. Therefore, a 
Sealevel I/O device with 16 inputs and 8 outputs would show two banks of inputs and 
one bank of outputs. 
When banks of inputs are displayed, the status LEDs update on each of the banks 
automatically. This allows you to actively monitor external signals. 
With a bank of outputs, the output coils can be set using the buttons below each 
output LED. As each coil is set, the I/O module is read. The corresponding status 
LED in the “Digital IO” window indicates the state of the coil. In the example 
below, a SeaI/O module with 16 Reed relays is shown.
