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 to be connect to a pair of network wires of the locomotive, and a second pair of terminals to be connected to a power source;
a display and input device on the housing;
a controller assembly connected to the first pair of terminals as a node on the network, connected to be powered by the second pair of terminals, connected to drive the display and connected to receive inputs from the input device;
a transceiver for wireless communication with the ECP system; and
an adapter connected to the transceiver and the first pair of terminals to interface the transceiver to the controller assembly via the network.

Abstract
An operator interface unit, includes a housing with a first electrical port having a first pair of terminals to be connect to a pair of network wires of the locomotive, and a second pair of terminals to be connected to a power source. A display and input device are on the housing. A transceiver assembly wirelessly communications with the ECP system. A controller assembly is connected to the first electrical port, the display, the input device and the transceiver assembly, and wherein the controller assembly is a node on the network via one of the first electrical port and the transceiver assembly. A portable assembly includes a battery source in a container which irremovably houses the operator interface unit.
