Key features:
Dual-mode operation Smart switching
The RD980 supports both digital and analog modes, which intelligently select the working channel based on the type of signal received, saving you the effort.
Leading time-to-time multi-site technology
The use of time-to-time multi-site (TDMA) technology significantly increases spectrum utilization. Double the user capacity of traditional FDMA systems.This helps to save money on base stations, frequency licensing, etc., while easing the pressure on increasingly tight spectrum resources.
Attachment extension
The RD980 supports third parties to use signal flow and transit station secondary development PIN port control to complete the development of the front and rear panel secondary development interface attachment extension functions of the transfer station.
Excellent thermal performance
The original thermal tube heat sink is complemented by a temperature-controlled cooling fan design that allows heat to dissipate quickly, ensuring that the equipment can also operate smoothly at 100% full power.
Convenient management software
With the management software, you can remotely control and diagnose the transfer station.In addition, you can record or play audio at any time in digital mode.
Original iris LED design
The original iris LED design blend fashion and practical as a whole, supplemented by 2.0 inch HD color screen, not only can you make you on the transfer station work status at a glance, but also can bring you a pleasing visual experience.
Secure digital encryption technology
Advanced 128-digit encryption technology protects your communications from illegal eavesdropping by others.
Remote diagnosis and control of the transit station
The RD980 supports remote (connected to the Internet by IP port) and local diagnostics (by USB) PC applications to monitor, diagnose, and control the broker status to increase productivity.The RDAC software developed by Heinenda supports multi-site network connectivity, allowing administrators to monitor intercoms accessing the network.
Digital voice flow in dual time slots
With the attachment pin, the RD980 supports the voice flow of two voice time slots, while also allowing third parties to extend its functionality.
IP Interconnection
The RD980 supports the interconnect of the transfer stations that make up the personal intercom network via IP ports, allowing for data and voice communications across a wide range of distributed areas.
Up to 50 watts of power
The RD980 supports a maximum power of 50 watts, thus increasing system coverage and reducing installation equipment.
16 Channels
The RD980 supports up to 16 channels, and each channel allows effective intercom network control, allowing you to use the RDAC PC tool, the front panel channel knob of the broker, or the end pin of the broker to complete the channel switching.
Analog/Digital Coexistence Working Mode
The RD980 supports a mix of analog and digital working modes.
Analog/Digital Back-to-Back
The RD980 supports different modes of operation after analog and digital back-to-back voice cross-connections, allowing analog users to communicate with digital users and vice versa, ensuring a smooth transition to digital.
Simulated prohibited transit
The RD980 supports a prohibited transit function, and when the pin port of the rear panel attachment in the turntable activates this function, the transit launch path is prohibited.
Doya Decoding
The RD980 supports decoding up to 16 subtones on analog channels, allowing different analog voices to be transferred to various groups of users.
Simulated scanning
The RD980 supports analog voice and signaling scanning, allowing different analog voices to be transferred to various groups of users.
Transit station access management
The RD980 supports intercom users access to the control of the broker to prevent illegal users from accessing the intercom network more securely.
Analog/digital telephone interconnection (via DTMF signaling)
The RD980 supports one-way calls between intercom users and phone users. Allows a walkie-talkie user to make a phone call to a telephone user, or a telephone user to make a call or group call to the intercom user.This feature uses commercial off-the-shelf (COTS) analog telephone devices and ordinary old-fashioned telephone services (POTS) to connect walkie-talkie users to a public office telephone system (PBX) or a public switching telephone network (PSTN).
Continuous waveform identification
The RD980 supports the transfer station to transmit Morse code format identification numbers.
