Profile
Compliant with the standard TJ/DW179-2015《Tentative Technical Specifications of Dual-mode End-of-train Safeguard System》.
Compliant with the standard TJ/DW180-2015《Tentative Technical Conditions of Dual-mode End-of-train Safeguard Equipment-End-of -train Cab Radio》.
With 2 communication mode: 400MHz and GSM-R.
Solve the problem of far communication distance in mountain area or tunnels.
Adopt the visualized operating terminal with friendly-interface and easy to use.
With build-in antenna combiner, only one piece of multiband antenna need external connection.
Self-adapted in the connection and installation of both single control-box and dual control-box, which is easy to match different train type.
Both main frame and control-box have USB interface to maintain and record data.

Product Function
Locomotive No., main frame ID, connection status, wind pressure, end-of-train index information, GSM-R communication status and etc, could be simultaneously displayed
Searching the wind pressure automatically and manually, controlling the brake in the end-of-train, receiving the alarm of abnormal wind pressure of end-of-train and low-battery level, interface displaying and voice promoting
Set the parameters of end-of-train cab radio, including the locomotive No., network parameters and etc.
The main frame of end-of-train could be connected, disconnected and off-Number
Data record and download
Reset the end-of train cab radio with controller reset switch
Automatically calibrating the time through the out-bound & in-bound locomotive detecting system of the end-of train cab radio.
Technical Parameters
It is used for the safeguard system of dual-mode freight train tail, monitoring the main frame in the end-of-train by wireless communication and controlling the brake in the end-of-train.
