NHRC-4 User Guide
1. Introduction
This manual describes how to install and set up the NHRC-4 repeater controller. This manual
should be used in conjunction with the NHRC-4 Operating Manual, which describes the
programming and operation of the controller.
2. Installation
This section of the User Guide describes the electrical interfaces used to connect the
controller to:
•
Power and primary repeater
•
Link/Remote Base radio
•
Communications Specialists TS-64 CTCSS Encoder/Decoder
•
Optional NHRC-DAD digital audio delay board(s).
It is intended for the repeater operator to use in the planning and installation of the NHRC-4
Repeater Controller into a repeater system.
The controller uses a 8 pin 0.100" header for all the primary radio's signals and DC power, a
6 pin 0.100" header for the secondary radio's signals, and a 6 pin 0.100" header for an
external TS-64 CTCSS encoder/decoder for the primary radio. In addition, it has two 4 pin
0.100" connectors to support optional NHRC-DAD digital audio delays for both radio ports.
Each radio port requires audio and a signal present indication (CAS) from it's receiver, and
supplies transmit audio and PTT to it's transmitter. The controller requires 13.8 volts DC for
power, which is provided on the primary radio's connector.. Be very careful when wiring DC
power to the controller, reverse polarity will severely damage the controller. The connector
pinouts are shown in the tables below.
2.1 Primary Radio Port Connections
The J1 connector contains the power and radio interface signals for the “Primary” radio port.
