Digital I/O Tab (cont.)
When displaying SeaDAC Lite modules, the “Digital IO” tab displays inputs and
outputs in groupings (or banks) of four. Therefore, a SeaDAC Lite module with four
inputs and four outputs would show only one bank 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 SeaDAC Lite module is read. The corresponding
status LED in the “Digital IO” window indicates the state of the coil. In the example
below, a SeaDAC Lite module with four inputs and four Form C relays is shown,
with the state of the relays showing either normally-open (NO) or normally-closed
(NC).
NOTE: The “SeaIO Configuration” tab does not appear in MaxSSD when
using SeaDAC Lite modules since they have no configurable
communication settings.
