Convertible wireless display unit
First Claim
1. An operator interface unit for an electrically controlled pneumatic (ECP) system which interfaces a locomotive pneumatic train brake control system to a train of ECP brake equipped cars, the interface unit comprising:
- a housing with a first electrical port having a first pair of terminals configured to be connected to a pair of network wires of the locomotive, and a second pair of terminals configured to be connected to a power source;
a display and input device provided on the housing;
a controller assembly connected to the first pair of terminals as a node on a network so as to be powered by the second pair of terminals, to drive the display and to receive inputs from the input device;
a transceiver configured to provide wireless communication with the ECP system; and
an adapter connected to the transceiver and the first pair of terminals and configured to interface the transceiver with the controller assembly via the network,wherein the controller assembly has a second electrical port connected to the first and second pairs of terminals of the first electrical port.
