BrandMeister DMR Server has capabilities to send and receive telemetry messages of Hytera and Motorola radios.

Telemetry service allows:

• Remote check of input. Input can be active and inactive. Radio can send event of state change.
• Remote control of output. Output can be switched on (set), switched off (clear), toggled and pulsed
