The Qualcomm doesn't have that at Dayton. It will automatically switch after a certain amount of time not moving or when shut off, but drivers with long bids or open drivers who may get run hard any given night need to manually switch it over in order to not screw up our drive time as we drive around the building to a dock door or whatever.
Say you don't park and shut the truck off until 10 minutes after entering the gate. All the time driving to the dock door, unhooking, and driving to park the truck would go against drive time if it isn't manually switched to On Duty. Is your In-Yard box a way to force it to stay on duty when you're rolling? Ours stays On Duty as long as we stay under 15 mph in the yard.
