Harxon HX-DU8616D Pro UHF Radio Modem


Smart and High Efficient Radio Modem for RTK Applications



The HX-DU8616D Pro UHF radio modem from Harxon is an external high-power transceiver eRadio that supports 4G network. It is specially developed for surveying and mapping. It features long communication distance, low power consumption and intelligent and user-friendly design. With an OLED display, it supports menu operation, intelligent serial baud rate identification, starting-up status identification, interference detection, remote control and other functions.

The HX-DU8616D Pro can automatically identify RTK serial baud rate with radio data cable and provide a plug and play form for easy connection between eRadio and RTK.

The HX-DU8616D Pro provides dependable performance as either a base, or repeater working with other Harxon radio modems. In the store and forward operating mode, it receives messages, buffers the received data and transmits further to another substation.

The HX-DU8616D Pro also supports the Bluetooth of APP to configure data and updates radio status. Its diagnostic reporting software can realize the built-in reliability monitoring.

The HX-DU8616D Pro is also equipped with its unique ETALK communication protocol. Under the same conditions, ETALK protocol can significantly reduce the BER of weak signals and the communication distance can be increased.

The compact, rugged HX-DU8616D Pro is well suited for heavy-duty outdoor use. The IP67 full metal cover provides dust and water resistance.


  • Intelligent Serial Baud Rate Identification
  • Multi-operating Mode Identify
  • Convenient Mobile APP Operations
  • Exclusive ETALK Communication Protocol
  • Rugged Housing for Harsh Environments
