CHAPTER 1: INTRODUCTION
Welcome
Thank you for purchasing the ComLink BCR REPEATER FM Repeater System. As part of the ComLink series, the BCR
REPEATER has been developed to provide many of the features you, the communications user, have requested. The BCR
REPEATER gives you a feature rich scalable repeater platform to grow as your system needs grow. The BCR REPEATER
integrates the RF power of a dual fan-cooled 40-watt repeater with a high capacity ‘tone panel’ and a 16 channel base
station. The BCR REPEATER also provides a D-SUB 25pin accessory connector allowing for ease in interfacing your favorite
external peripheral such as a Tone/DC Remote, Telephone Interconnect, SCADA, or Telemetry fixture. We would also like to
say The BCR REPEATER repeater is 100% LTR compatible and can be used with your favorite LTR trunking controller. This
means the BCR REPEATER provides DC access from the receiver to the controller and from the controller all the way to the
RF transmitter without causing sub-audible signal degradation.
Features
• High Performance Specs: Temperature Compensation Oscillator (TCXO) ensures frequency stability and accuracy
during ambient temperature changes.
• Modular Design: The modular design of the BCR-40U/50V allows for ease and quick replacement of the internal
electronics at the site.
• Rack style design: The galvanized steel chassis construction provides for a Heavy Duty housing that can be mounted
in a standard 19” rack or desktop configuration taking up 3.5” of rack space. Standard equipped rack handles provide
for ease during 19” rack installation.
• Internal duplexer (optional): The design of the BCR-40U/50V’s chassis allows for an internal duplexer to be
installed.
• Front panel display and controls: The front panel of the BCR-40U/50V includes a LCD display and four LED status
indicators. Front panel controls include a four-button keypad, speaker volume control knob, and select control knob.
• Windows-based programmer: The BCR-40U/50V can be setup and maintained using the optional BCR programming
software. Programming is simple and easy – the ACC-8025 cable connects your PC to the BCR-40U/50V, no other
interface modules are needed.
• Signaling capability: Built-in High capacity ‘tone panel’ that supports up to 24 users per channel with 38 CTCSS tones
and 83 DCS codes available per channel. Cross tone/code encoding is available as well.
• Battery Backup: The BCR-40U/50V can be powered from a 12V battery and also provides a charging circuit for
maintenance free operation.
• External Speaker Out: Operate a high-powered external speaker by turning it on from the front panel.
• Built In Channel ID update: Sends station ID in programmable intervals. Select Morse send rate of 10-25 WPM.
• Integrated High-Efficiency Power Supply: The BCR REPEATER includes an internal 150W power supply with
MosFet-based switch-mode technology for high reliability, high efficiency and minimum size and weight. It also
provides 13.8V output for powering external controllers, thus saving valuable site resources.
• Dual Cooling Fans: The BCR REPEATER incorporates two cooling fans that can be programmed for continuous
operation or transmit only.
• Variable channel spacing: Each channel can be individually programmed to use 12.5 kHz or 25 kHz spacing making
the BCR-40U/50V useful for years to come.
• Remote Programming via DTMF tones: In order to save a time consuming trip to the site, the BCR-40U/50V
provides for remote programming and maintenance.
• Accessory Connector and AUX Feature: The internal controller can be disabled and the repeater placed in an
auxiliary mode where it can be used as a slave to an external controller.
• Air-Time Logging: The BCR-40U/50V automatically logs cumulative airtime on a per use basis. The airtime is
recorded in minutes and seconds and is accumulated on per second basis. The air-time data is then retrieved using the
BCR programming software.
