Indoor Wall Mountable Repeater

An indoor DMR and Analog dual mode repeater in a compact design, embedded with a power supply and optional mini duplexer. The Hytera DMR repeater's innovative design enables it to easily support wall- mount installation with AC/DC power. Multiple sites can connect via IP along with the RD982 to support flexible wide area and large building coverage. Integration with Hytera Dispatch System or other 3rd party GPS dispatching software can be achieved by the RJ45 port in the side of the repeater.
All-In-One Compact Design
Compact design, integrates RF, power supply, and optional duplexer into one box, which makes the Hytera RD622i smaller, lighter, and easier for wall-mount installation and indoor coverage (wall-mount bracket sold seperately BRK21).
Multi CTCSS / CDCSS Decode
This DMR UHF repeater decodes up to a maximum of 16 CDCSS/CTCSS codes in Analog channels allowing coverage for different Analog voice users from various groups.
Repeater Access Management
The repeater access control feature of the Hytera RD622i allows better security to prevent unauthorized users from accessing the radio network.
Analog Scan
This DMR UHF repeater has analog voice and signaling scan, allowing coverage of different analog voice users from various groups.
AC / DC Auto Switch
The Hytera RD622i integrates an internal power supply that supports a battery floating charge. The power supports 13.6V±15% DC and 90V-264V AC. If the AC power is cut off, the DC power (battery) automatically takes over without interruption.
Two repeaters can be interconnected to provide interoperability between UHF and VHF. A single repeater can auto switch between Analog and Digital mode, allowing for efficient frequency sharing between Analog and Digital users and an easy digital migration.
Digital Audio Streaming of Dual Time Slots
The streaming of both the voice slots via the rear port accessory pins on this Hytera DMR repeater, allowing for capability expansion via future development and recording of communications via Hytera Dispatch System.
Repeater Diagnostic And Control (RDAC)
Remote IP connection to monitor, diagnose, and control the repeater thus increasing maintenance efficiency. The Hytera developed RDAC is able to support multiple master network connections to allow the radio administrator to monitor multiple radio networks.
Multiple Sites via IP
Network connection via the IP port of this Hytera DMR repeater to form a privateradio network to meet data and voice communication needs for wide-area coverage and dispersed locations.
