The digital repeater RD985S is a genuine multi-talent: It supports not only conventional radio operation in analog and DRM modes, but can also be used in DMR trunked radio systems and, besides, is responsible for radio coverage in DMR Simulcast and Hytera XPT Systems.
The repeater was developed in conjunction with the open ETSI standard Digital Mobile Radio (DMR) and, thanks to its technical features, it is your perfect companion on the path toward digital radio.

Heart of professional radio systems
All the repeaters from Hytera can be connected in digital mode via IP connection to a comprehensive radio network. In analog mode, the repeaters can be connected together back-to-back. Both in conventional analog and DMR modes (DMR Tier II), the RD985 and RD985S repeaters can be used with the RD625 and RD965 repeaters in a radio system.

Upgradeable for greater challenges
The RD985S repeater supports not only conventional analog and digital modes, but also other modes that can be unlocked with an upgrade. It can be upgraded into a base station for DMR synchronization, DMR trunked radio or Hytera XPT radio systems. This means that the RD985S is a secure investment for growing radio projects.

Improved utilization of the frequency spectrum
Thanks to the TDMA technology, twice as many users can use the same channel, such as is the case with analog or digital FDMA systems. Due to the restricted frequency resources, this represents an important relief and reduces the expenses for system terminals and licenses.

Secure communication
To protect your radio communications against eavesdropping, the RD985S repeater possesses advanced digital encryption functions, according to the DMRA specification. Depending on the variant, it supports 40-, 128- or 256-bit encryption. With air interface encryption signaling and communications data between radios and repeaters are transmitted with reliable protection.

Dual mode and automatic change
The RD985S repeater can automatically change between digital and analog mode depending on the type of receiver signal.

High transmitting power
The RD985S repeater offers an adjustable transmitting power of up to 50?Watt and thereby satisfies the high requirements for modern PMR radio systems.

Extremely reliable
Since the RD985S was designed according to military standards, it offers high reliability and excellent performance. Test results from independent laboratories have shown that the device can be operated for up to 100,000 hours without interference (MTBF) and it therefore meets the requirements for use in extreme situations.

Flexible installation options
The RD985S can be installed in a 19-inch equipment rack with an optional installation kit. Alternatively, it can easily be operated on a rack, a bracket or a table. With the additionally available installation kit, an optional duplexer can be housed in the chassis.

High cooling capacity
The booster can dissipate any generated heat with extraordinary efficiency. In addition, the integrated fan system ensures stable and powerful operation.

High-resolution 2-inch LCD color display
Whether during ongoing operation or during a maintenance task: You can easily access all the desired information via the large LCD color display.

Professional design
Integrated LEDs on the volume controller complement the innovative repeater design and simultaneously optimize its use. The repeaters are easy to use thanks to their clear menus and the large navigation controller.

Clear LED indicators
The 8 LED indicators on the front allow the current repeater status to be easily identified
