CHAPTER 1

Intr oduction

Overview

The ADHB-4 (Advanced Digital Headset Box - P/N PRD000262000) is easy to install and configure dispatch audio system

that adds microphone and speaker capabilities, in various forms, to a C-Soft console. The ADHB-4 replaces the sound card in

the PC, offering the flexibility of controlling a wider selection of audio options.

Audio input and output is routed to devices by connecting a combination of headsets, desk mic, speakers, or a telephone to the

unit. Electret and dynamic microphones are both supported. Additionally, a footswitch can be installed for hands-free

operation. The unit can be mounted on the desktop or below it. Standard cable connections are made directly to a PC, to access

C-Soft, and an Ethernet connection for firmware upgrades, and unit configuration.

Audio parameters are set up within the web browser configuration software. Access to the radio dispatch system is provided

by configuring the base IP Address, Subnet Mask and Gateway within the ADHB-4 software. Additionally, the input and

output gain control, PTT (Push-T o-Talk) source, and PTT priority are configured for the connected audio equipment. Status is

conveniently summarized on one (1) window in the configuration software for quick evaluation of connected audio devices.

The front panel is equipped with a color TFT-LCD (Thin Film Transist or-Liquid Crystal Display), allowing instan t

indications for ADHB-4 activity. The console operator can quickly determine which device audio is being routed to/from, as

well as footswitch activity, volume, transmit status and receive status. A bar graph indicates the headset volume level and can

be changed with the volume buttons on the front panel. A system information menu is also available. A single LED (Light

Emitting Diode) on the front indicates power when green and PTT when red. A single red LED on the left side panel indicates

phantom power is enabled when red and disabled when dark.

Softkeys on the front panel allow the console operator to change the clock, adjust the display’s backlight brightness, and

change the IP Address and Subnet Mask.

ADHB-4 Mounting

ADHB-4 Mounting

Mounting

The ADHB-4 is mounted on or under a surface such as a desk by either placing it on the work surface or using mounting
brackets to fix it in place.

• Ensure there is enough clearance for back and side panel connections.

• Provide space for at least one (1) speaker pair.

NOTE: A dispatch monitor, weighing up to 35 lbs. maximum, can be placed on top of the unit.

ADHB-4 Mounting Brackets

The ADHB-4 can be mounted on the underside or topside of the surface using optional ADHB-4 mounting brackets. For part
number information, see “Optional Hardware” on page 14.

Underside Mounting

To install the ADHB-4 on the desk underside, do the following:

1. Remove the top screws (B), from the sides of the ADHB-4.

2. Using the screws removed in step 1, attach the brackets (A) to the sides of the ADHB-4 as shown in Figure 4.

3. Hold the ADHB-4 in the desired mounting position.

4. Using a pencil, mark hole positions on the mounting surface.

5. Drill holes to accept a #4-40 x 1/4” screw (C).

6. Using the screws (C) supplied with the bracket, attach the ADHB-4 to the mounting surface.

ADHB-4 Connections

ADHB-4 Connections

USB Port

The USB port is used to connect the ADHB-4 directly to a PC. The USB connection is required to send the audio and control
data between C-Soft and the ADHB-4.

IMPORTANT : If it is necessary to disconnect the USB from the computer or ADHB-4, the USB device should be

safely removed.

To safely disconnect the USB from the computer, do the following:

1. Close the C-Soft console.

2. Safely remove hardware.

REFERENCE:For more information, see your operating system user manual.

3. Disconnect the USB from the computer and ADHB-4.

10/100 NETWORK Port

The NETWORK port is used to connect an Ethernet cable to the ADHB-4.

PHONE Jack

The PHONE jack is used to connect a POTS (Plain Old telephone Service) handset, fitted with a mini RJ 4-pin-connector, to
the ADHB-4. This jack can also be used to connect to a phone system.

To connect to a phone system, do the following:

1. Remove the handset from the phone (at the handset side of the wire) leaving the wire connected to the main phone.

2. Connect the line directly to the phone jack.

NENA Jack

The NENA jack is used to connect a NENA phone with an RJ-12 connector, to the ADHB-4 allowing full duplex
conversation. NENA operation is only permitted when headset(s) are selected and detected for use at the dispatch position.The
offhook condition is triggered by a contact closure that is part of the NENA jack wiring.

The NENA connector wiring diagram is shown in Figure 6. Pin out s for the RJ-12 connector are shown in Figure 7.

Installation

NENA Phone Connector

The NENA Phone connector description:

• ADHB-4 connects to NENA from the RJ-12 connector.

• Balanced 600 Ohm audio in and out to eliminate ground loops.

• Telephone RX audio routed to headset for entire offhook duration.

• Radio RX audio routes to console when telephone goes offhook.

• The hook switch input is diode protected from voltages above 5VDC.

RJ-12 Connector

An RJ-12 connector provides input/output for a NENA port. When the NENA is taken offhook, the input transitions from high

to low and NENA RX audio is routed to the active handset or headset’s earpiece while NENA TX is routed from the active

handset or headset’s microphone.

NOTE: A headset or handset is required for NENA use. A desk mic cannot be used on a NENA.

FOOTSWITCH Jack

The FOOTSWITCH jack accepts a 3-pin connector that has one (1) or two (2) footswitches connected to it. The input for

PTT uses pins 1 and 2. The input for monitor uses pins 2 and 3. The PTT footswitch can control the PTT functions for the

headset, RHB 1 or 2, or the desk mic depending on the configuration.

ADHB-4 Connections

ACCESSORY Port

The ACCESSORY port is used to connect optional equipment, to the ADHB-4.

The ADHB-4 accessory port provides two (2) balanced recorder outputs designed with 600 Ohms impedance. The common
recorder output sums and amplifies all common audio to a balanced output for single position capability.

NOTE: Version 1.00 does not support recording audio routed to speakers 3–6.

AUX TTL Level Inputs

The AUX 1 and AUX 2 connections detect a contact closure and sends the information to the C-Soft application. Each
input is diode protected from voltages above +5VDC.

These inputs are:

• DC Isolated

• Diode Protected

• Active Hi/Low (configured in C-Soft)

Form C Relay Contacts

The ADHB-4 provides two (2) Form C relay contacts for general use. Each relay is (separately) controlled from C-Soft. A
1Amp resettable fuse protects both sets of contacts.
