Auxiliary Output

[Jabe]

Hello, I'm using a M880. I have set up an ignition switch as a discrete input. I want to switch-to-ground an auxiliary output (AUX 2) discrete when the ignition switch is asserted (switched to ground). I find no functions for setting the auxiliary outputs as a function of a discrete input, except perhaps the Auxiliary Table or a User Channel, however the setup of the auxiliary table doesn't have a discrete as the independent variable (or X-axis) although there is a listing of a user channel but no information on the user channel setup with discretes.

How can I assert the auxiliary output discrete as a function of an input discrete; i.e. the ignition switch?
Thanks in advance.
