DMR Repeater VP-805
As a DMR Tier2 and Tier3 product with ergonomic design, totally digital functionality, the VP-805 helps to improve management efficiency and a faster response in emergency situations.
KEY FEATURES AND BENEFITS
Professional 1U Design
Professional 1U design saves installation space.
Outstanding Heat Dissipation
The unique cooling design combines a built-in heat pipe and four fans design ensuring very efficient heat dissipation, preventing the repeater from over-heating in high output power mode.
Smart Digital-Analog auto detection
VP-805 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
VP-805 supports third party development via a rear port of the repeater. This is achieved via the pin control through the repeater ports. SIP and AIS protocol supported for easy expansion
IP Connecting
IP connection is a function which enables repeaters in different areas to switch data, voice and packets over a TCP/IP based network.
LED Indicator
9 LED indicators on the front of panel enables you to identify the repeater status clearly.
Software Upgradable to DMR Tier2 or Tier3
The advanced features can be upgraded to your existing VP-805 repeaters by software without purchasing a new one. By software upgrade, the repeater can be used as a DMR Tier2 repeater or DMR Tier3 transceiver
