I/O Configuration
The I/O Configuration dialog is used to setup and test the optional USB relay I/O
module. The relay module has four Form-C relays that offer a normally open and a
normally closed connection. The relay outputs can be tested using the toggle button.
The toggle button will toggle the state of the N.O. and N.C. outputs. There are four
LEDs on the I/O module itself to show the current state of the relays. When the output
LED is lit for a given relay, the N.O. relay will be closed and the N.C. will be open.
Each relay output can be assigned to one or more tolerance conditions using the
check box selectors.
