RD985 DMR Repeater for Small Radio Networks
The RD985 and RD985S DMR repeaters from Hytera are at the heart of analogue
and digital radio networks and were developed in line with the open ETSI
standard for DMR.
Both repeaters are characterised by their reliability and outstanding
functionality.
Highlights
Both repeaters can be operated in analogue and digital mode and are completely
compatible with analogue systems currently in use. In addition, the RD985S is
a true all-rounder. As well as DMR trunked radio (Tier III), it also supports
use in Hytera XPT and simulcast radio systems.
Both repeaters were developed according to the open ETSI DMR standard and,
thanks to their technical features, they are your perfect companion to deliver
a professional digital radio network.
The 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 analogue mode, the repeaters
can be connected together back-to-back. Both in conventional analogue 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 (RD985S)
The RD985S repeater supports not only conventional analogue and digital modes,
but also other modes that can be unlocked with a chargeable licence. It can be
upgraded into a base station for DMR simulcast, DMR trunked radio (Tier III)
or Hytera XPT radio systems. This means that the RD985S is a secure investment
for growing radio projects.
Dual mode and automatic change
Both repeaters can switch independently between the digital and analogue
modes, depending on the type of the receiver signal.
Secure communication
To protect your radio communications, the RD985 and RD985S repeaters offer
advanced digital encryption functions, according to the DMRA specification.
Depending on the variant, both repeaters support encryption with 40, 128 or
256 bit.
Powerful and reliable
High transmitting power
Both repeaters offer an adjustable transmitting power of up to 50 watts and
therefore satisfy the high requirements for modern PMR radio systems.
Extrmely reliable
As they are designed to military standards, both repeaters offer consistently
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 RD985 and RD985S repeaters can be installed in a 19-inch equip- ment rack
with an optional installation kit. Alternatively, they can be operated simply
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 power amplifier can dissipate any generated heat with extraordi- nary
efficiency. In addition, the integrated fan system ensures stable and powerful
operation.
