Hytera RD625 – DMR repeater

Compact DMR repeater for wall mounting.

The RD625 is a digital repeater designed specifically to provide reliable radio coverage in buildings and tunnels. The RD625 has been developed in accordance with the Digital Mobile Radio (DMR) open ETSI standard and can be operated in digital or analog.

  • Multiple Sites via IP
    RD62X supports network connection via the IP port of repeater to form a private radio network to meet data and voice communication needs for wide-area coverage and dispersed locations.
    Digital Audio Streaming of Dual Time Slots
    RD62X supports the streaming of both the voice slots via the rear port accessory pins, allowing for capability expansion via future development.
    Analog/Digital Operating Mode
    RD62X supports operating mode in both Analog and Digital.
    Analog Scan
    The RD62X supports Analog voice and signaling scan, allowing coverage of different analog voice users from various groups.
    Repeater Diagnostic And Control (RDAC)
    RD62X 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.
    AC/DC Auto Switch
    RD62X 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.
    Analog/Digital Back-to-Back Interconnect
    RD62X supports different operating modes of Analog and Digital to interconnect for voice cross patch, allowing Analog users to communicate to Digital users and vice versa. This allows for a smooth migration for Analog users to the digital world!
    Multi CTCSS/CDCSS Decode
    RD62X supports decoding up to a maximum of 16 CDCSS/CTCSS codes in Analog channels, allowing coverage for different Analog voice users from various groups.
    Analog/Digital Telephone Interconnect
    RD62X supports simplex voice communications between radio and telephone users. It allows a radio user to make a telephone call; or a telephone user to make either a Group or Private call to radio users. This feature utilizes the Commercial off the Shelf (COTS) Analog Phone Patch boxes and a Plain Old Telephone Service (POTS) line to connect the Repeater to the Corporate Office Phone System (PBX) or Public Switched Telephone Network (PSTN).
    Analog/Digital Auto Switch
    RD62X supports Analog and Digital channel auto switching, allowing for efficient frequency sharing between Analog and Digital users and an easy digital migration.
    All-In-One Compact Design 
    RD62X’s compact design, integrates RF, Power supply, and duplexer into one box, which makes RD62X smaller, lighter, and easier for wall-mount installation and indoor coverage.
    Repeater Access Management
    RD62X supports a repeater access control feature allowing better security to prevent unauthorized users from accessing the radio network.
    Notes: RD62X, X=0, 2, 5 or 8, model number varies geographically. For details, please contact our regional sales representatives.

  • Flexible IP networking
    Hytera’s DMR repeater can be connected to an IP-based communication network with multiple locations. The roaming function is used to provide radios in this radio network with voice and data services across cells.

    Connecting VoIP private automatic branch exchanges (PABX)
    The RD625 repeater makes it possible to connect existing VoIP telephone systems to the DMR radio network. This allows DMR radio subscribers to hold half-duplex conversations with participants from the telephone network. Telephone subscribers have the option of making either individual or group calls in the radio network.

    Analog and digital operation with the ability to switch automatically
    The RD625 repeater can be operated both in analog and in digital mode and is completely compatible with analog systems currently in use. The device can automatically change between digital and analog mode depending on the type of receiver signal, saving both time and money by eliminating the need to configure frequencies and channels manually.

    Automatic AC/DC switchover
    The integrated power supply of the RD625 automatically chooses between alternating current and direct current. This makes it possible to provide a fail-safe radio signal by connecting the repeater to an independent source of direct current (UPS) in addition to the normal supply of power. If the AC supply fails, the RD625 switches to the second power supply automatically.

    Easy installation
    The RD625’s well-engineered design makes wall mounting easy using the optionally available wall bracket. This makes it possible to install the repeater flexibly and conveniently in buildings.

    Repeater diagnostics and control system (RDAC)
    A PC-based application can be used to monitor, inspect and control the RD625. The software supports network access from multiple points and allows administrators to monitor the DMR radio network.

    Compact all-in-one design
    The RD625 combines transmitter and receiver components, the voltage supply and the duplexer (optional) in its compact chassis.

    Repeater access management
    To ensure a high level of security, the RD625 features a repeater access monitor that protect the radio network from unauthorized access attempts.
