Professional 3U Design
Professional 3U design leaves enough space for an added duplexer and is suitable for both desk-top, cabinet and rack installations.
Outstanding Heat Dissipation
The unique cooling design combines a built-in heat pipe and an intelligent control fan, ensuring very efficient heat dissipation preventing the repeater from over-heating in high output power mode.
Smart Digital-Analog auto detection
TR850 can be configured to analog, digital or mixed mode. When configured to mixed mode, the repeater can dynamically switch between analog and digital depending on the type of call it receives.
Accessory Expansion
TR850 supports third party development via a rear port of the repeater. This is achieved via the signal streaming and pin control through the repeater ports.
IP Connecting
IP connecting is a function, which enables repeaters in different areas to switch data, voice and packets over a TCP/IP based network.
LED Indicator
There are 9 LED indicators on the front of panel to enable you to identify the repeater status clearly.
Software Upgradable to DMR Tier2 or Tier3
The advanced features can be upgraded to your existing TR850 repeaters by software without purchasing a new one. By software upgrading, the repeater can be upgrade to used as DMR Tier2 repeater or DMR Tier3 transetransceiver.
