NHRC-10 User Guide

1. Introduction

The NHRC-10 Repeater Controller represents the current state-of-the-art in repeater

controller designs. It utilizes the latest available technology to provide maximum

functionality with the lowest number of parts. This results in very reliable operation.

The key features of the NHRC-10 are:

• Recording of four real speech ID messages and three real speech tail messages

yourself.

• Local language support using a custom recording capability.

• Six voice mailboxes, five saved operational setup memories, ten timers, and more

than 70 control operator functions.

• An audio test mode that records and plays back user's audio.

• A full-duplex autopatch with a database of 100 autodial numbers plus ten emergency

autodial slots.

• Support for up to four area codes with grant/deny access control to each exchange.

• Land line telephone access for "Reverse Patch" & controller administration.

• DTMF (“Touch Tone”) pad test.

• Dedicated DTMF receiver for telephone control and optional control receiver. (A

separate control receiver audio input with dedicated DTMF receiver is available.)

• Separate control receiver jack and DTMF receiver. DTMF receiver reverts to link

port when control receiver is not present.

• Connections for remote base, link radio, or slave repeater.

• Unique courtesy tones to indicate link/remote base status.

• Frequency-agile remote base supports remote control of ICOM IC-706MkIIG.

• LiTZ (Long Tone Zero)/911 message support; will play dedicated voice message in

response to LiTZ or 911 tones to tell user how to use emergency autodials, what

other repeater to use, etc.

• Transmitter fan control output automatically runs fan while transmitting and for a

programmable delay after.

• Real sine wave audio tones.

• DTMF "Carrier,” “Carrier and CTCSS,” and “Carrier or CTCSS" access modes.

• Granular security features that allow tailored control operator access.

NHRC-10 User Guide

1.1 Sending commands

All of the controller’s commands are sent by DTMF (Touch-Tone) sequences that can

be received on the main repeater, over the telephone, the control receiver (if connected),

or the link radio (if the control receiver is not connected).

Commands received over the main repeater or link radio will be evaluated, and if correct,

executed, when either the DTMF inter-digit timer expires (2.0 seconds) or the CAS

(receiver unsquelched) signal drops; whichever comes first. This allows the controller to

be commanded even when a weak on-channel signal is holding the receiver’s squelch

open.

The telephone and control receiver do not have a CAS signal available. Commands

received from these sources will be evaluated when the DTMF inter-digit timer expires.

To send a command over the main repeater,

1. key your transmitter.

2. enter the DTMF command digits.

3. unkey the transmitter.

This will cause the command to be evaluated immediately.

If you pause for more than 2.0 seconds while sending a command, the command you

entered prior to the pause will be evaluated, the command buffer will be emptied, and

you can immediately enter another command.

When a command is successfully evaluated, the controller will send a response. Each

command’s possible responses are detailed with the command description.

In general, if you do not receive a command response, then the controller did not accept

your command.

1.2 ID Messages

The controller supports four voice ID messages and one CW ID.

The voice messages are comprised of:

• an “initial” ID message, that plays when the controller has been idle for a period

longer than the ID timer, and

• three “normal” ID messages.

Each of the normal ID messages can be individually enabled or disabled.

When more than one normal ID message is enabled, the enabled messages are played in

sequence; one each time the ID timer expires.

The CW ID will play when all the voice IDs are disabled, or when the repeater is keyed

during a voice ID message.

NHRC-10 User Guide

1.3 “Unlocked Mode”

All of the controller’s important programming information is protected by a special

password, the “unlock code.”

Programming the unlock code requires physical access to the controller to place a jumper

on the circuit board.

The unlock code cannot be re-programmed without physical access to the controller.

When the unlock code is successfully entered into the controller, the controller will say

“control access enabled,” and a special courtesy tone will be used to indicate the

controller is unlocked.

The controller can be locked by:

• sending the “#” command, or

• it will lock itself after two minutes of inactivity.

When the controller leaves the unlocked mode:

• it will say “control access disabled,” and

• the courtesy tone will revert to the normal tone for the controller’s current state.

NHRC-10 User Guide

2. Electrical Connections

This section of the User Guide describes the electrical interfaces used to connect the

controller to:

• power,

• repeater and link radios,

• the control receiver, and

• NHRC-DAD digital audio delay boards.

It is intended for the repeater operator to use in the planning and installation of the NHRC-

10 Repeater Controller into a repeater system.

2.1 Input and Output Signal Levels

Control signals into the NHRC-10 are active-high signals. The repeater activity inputs

(CAS and CTCSS Decode) are buffered in the controller to allow the connection of

popular radios to the controller. Signal levels should be 0.0 to 0.5 volts for off, and 2.0

to 16.0 volts for on.

The controller’s PTT and FAN CONTROL outputs are “open-drain” connections to

power MOSFETs. These outputs are active-low, and when activated, will pull the

control signals to within a few ohms of ground. These outputs can sink 100 mA or so.

NHRC recommends that diodes be used to protect the MOSFETs from back-EMF if

these signals are used to drive relays.

Audio signals into the controller should be in the range of 0.2 to 2.0 volts peak-to-peak.

The controller’s transmit audio outputs are adjustable from about 0.1 volt to about 5

volts peak-to-peak.

The optional NHRC-10_DOUT digital output board provides eight additional digital

outputs. These outputs are “open-drain” connections to power MOSFETs. These

outputs are active-low, and when activated, will pull the control signals to within a few

ohms of ground. These outputs can sink 100 mA or so. NHRC recommends that diodes

be used to protect the MOSFETs from back-EMF if these signals are used to drive relays.
