Description

Rich Data Protocol

TRU35 supports lots of protocols including TrimTalk, TrimMark, Satel, PCC, South, Hi-target…

All in One

TRU35 is integrated with transmitting and receiving functions for different kinds of applications.

Radio Relay

Increase the transmitting distance by receiving data and transmitting it out with another frequency.

Voltage Protection

Two-stage surge protection is used to protect the radio from damage when the input voltage or current exceeds the normal range or positive and negative stages are reversed.

Standing Wave Detection Protection

Prevent damage caused by long-time open circuits or short circuits.

Thermal Protection

TRU35 can adjust the transmit power adaptively, automatically reduce the power when the temperature is too high, and increase the power when the temperature decreases to ensure radio equipment is always in a stable power range and will not be damaged by overheating.

IP67 Protection

Bluetooth Function

Bluetooth can be used to configure operating mode, protocol, frequency, and power level. Bluetooth can be also used as a replacement for cable to receive correction data.

Long Transmission Distance

Transmission distance can reach 25Km in optimal conditions.
