ZNP801
Purpose
The ZNP801 is a system used to alleviate much of the vocal communication between dispatchers in neighbouring signal boxes. Offering, accepting, refusing, and cancelling of trains are supported by this system. Additionally, train numbers can be changed on the panel.
Operation
The system works by collecting a series of values and commands. When the sequence has been entered, the dispatcher sends the commands to a neighbour. The neighbour, using his ZNP801, makes a decision about how to handle the request.
Offering Trains
To offer a train, you need to enter the train number, followed by the station to which you're sending the train, followed by the track number, and completed with the "ANB" command. "ANB" indicates that this is an offering. For example, sending train "3435" with steering number "1" to neighbour "XYZ" on track "123", you would enter:
To actually send the command, press "ZNS".
