When you set a V-Port address under the “V-Port” column you are saying that the relay is to listen
for events on this V-Port and take commanded action if appropriate.
A corresponding V-Port should be configured on an output channel such as a Panel Controller, PC or
DCC interface.
Feedback V-Port
The Feedback V-Port will generate an event from the relay driver to indicate its position.
The feedback V-Port is normally configured when the relay is not being used to switch frog polarity.
When used as a frog polarity switch with a servo driver the servo driver will usually generate the
feedback event on the feedback V-Port.
Reversing a relay channel
Selecting the reverse box (indicated by a tick) will cause the relay to immediately reverse. Clicking it
again will undo the action.
