Hytera DMR Compact Repeater
RD628
Compact and light indoor repeater RD628 is a new addition to Hytera’s migration products. The innovative design allows easy wall-mount installation with AC/DC power. DR628 is a dual, analogue/digital repeater with embedded mini duplexer and power supply. Analogue/digital back to back interconnect facilitates easy communication between analogue and digital users while telep..
Multi-Sites via IP
Network connection via the IP port allows to create a wide-area private radio network for voice and data communication.
Analogue/Digital Back-to-Back Interconnect
Analogue/Digital operation enables analogue users to communicate to digital users and vice versa. This feature is particularly important for a smooth migration from analogue to digital world.
Digital Audio Streaming of Dual Time Slots
Streaming of 2 voice slots is possible via the rear port accessory pins, allowing for capability expansion via future development.
Multi CTCSS/CDCSS Decode
RD628 supports decoding up to a maximum of 16 CDCSS/CTCSS codes in analogue channels, allowing coverage for different analogue voice users from different groups
Analogue/Digital Telephone Interconnect
This feature allows a radio user to make a telephone call; or a telephone user to make either a group or private call to radio users.
AC/DC Auto Switch
RD628 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.
Analogue/Digital Operating Modes
RD628 supports operation in Analogue and Digital modes.
Analogue/Digital Auto Switch
Analogue and Digital channel auto switching allows for efficient frequency sharing between Analogue and Digital users and an easy digital migration.
Analogue Scan
The RD628 supports analogue voice and signalling scan, allowing coverage for analogue voice users from different groups.
Repeater Diagnostic and Control (RDAC)
RD628 supports 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.
All-In-One Compact Design
RD628 compact design, integrates RF, power supply, and duplexer into one box, which makes this repeater smaller, lighter, and easier for wall-mount installation and indoor coverage.
Repeater Access Management
RD628 supports a repeater access control feature allowing better security to prevent unauthorised users from accessing the radio network.
