6.17.2 How to setup the warning/error output
Pin 2 acts as a built-in switch in the Communication Unit. Pin 2 can be used to provide
an external signal that indicates active warning/error condition(s). You can configure
pin 2 to be active ground or active open.
1. Referring to section 6.1, login as an Administrator.
2. Click [Admin] in the menu bar.
3. Click [Discrete I/O Settings] to show the [Discrete I/O Settings] menu.
4. Put a [9] in the box on the left side of [Enabled] (click the box to add [9]) in the
[Alarm] field to activate alarm function.
To deactivate this function, uncheck the [9] in the box (click the box to delete [9]).
5. Select from [Active open] or [Active ground] in the [Alarm] field.

ground). When an alarm occurs, the switch is closed (connected to ground). The
switch is opened again when all warnings/errors are cleared.
