screen is displayed.

Note the outputs on the hub card are always indicated first

Select the relay to test to 
see it change its state

Use the NEXT and PREV buttons to select the desired relay 
board.
There are also screen displays for individual ‘module’ outputs.

Use EXIT to 
return to the 
main menu and 
release all
