            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.
