4 HB-3Plus Headset Adaptor Box

1 General

The Vega HB-3Plus Headset Interface Box is a reliable method for connecting a desk microphone,
headsets and footswitch controls to any computer running Vega’s C-Soft program or any Vega dispatch
console. A bi-color front panel LED indicates power (green) or active PTT (red).

The HB-3Plus connects directly to the handset jack of the dispatch control console or a PC operating with
the Vega C-Soft dispatch software. In the console mode, an RJ11 4 conductor cable provides the
connection from the HB-3Plus to the console. Connections to the PC serial port and sound card provide
PTT, monitor, relay and Aux input control in the PC mode.

The HB-3Plus also provides a connection to any telephone device with a NENA I/O port, allowing for a
single headset to be shared by the radio and phone system. When the phone set is taken off-hook, the
headset microphone audio is routed to the phone system and selected radio is transferred back to the
SELECT speaker. Telephone audio is routed to the headset as long as the system is off-hook.

The HB-3Plus Features:

• 2 Dual ¼’ headset jacks

• Independent SELECT volume controls

• Switch selectable headset on/off

• 1 Desk microphone input

• 3 Independent footswitch inputs

• Power and PTT LED indicator

• 1 NENA I/O port

• 2 AUX relays (Form C contacts)

• 2 AUX IN TTL inputs

• Balanced common recorder output

• Separate balanced UNSELECT audio recorder output

• +9VDC 50mA output

Jumper Selectable Options:

• PC/Console Mode

• C-Soft mic output level set (Mic/Line)

• Electret/Dynamic desk mic select

• Route UNSELECT audio to headsets

• Route UNSELECT audio to common recorder output

• +9VDC/GND (Pin 6 of footswitch terminal block)

2.2.3 Headset I and II Connections

The HB-3Plus operates with either 4 or 6 wire Dual ¼” Phone Jack plugs. The standard
configuration for the HB-3Plus is for operation with a 6-wire plug configuration. The horizontal lines
adjacent to the right phone jack of each headset pair indicate the negative polarity of the mic bias.

Headset I

JMP12 – Routes SELECT or UNSELECT audio to the headset I
A – UNSELECT and SELECT audio to headset I
B – SELECT only audio to headset I

Cutting the small trace between JMP13 disables the PTT function for 4-wire headset operation

Headset II

JMP3 – Routes SELECT or UNSELECT audio to the headset II
A – UNSELECT and SELECT audio to headset II
B – SELECT only audio to headset II

Cutting the small trace between JMP6 disables the PTT function for 4-wire headset operation.

2.2.4 Desk Microphone Connection

The HB-3Plus is designed to operate with the MD-MS electret
desk microphone or the Model 6513C dynamic desk
microphone. Internal jumper JMP2 selects the electret or
dynamic microphone configuration.

A – Electret

B – Dynamic

When using a desk microphone the Headset On/Off switch
should be in the OFF position to route SELECT audio to the
speaker.

Figure 2 Desk Mic Connector

2.2.5 Headset ON/OFF switch

The headset ON/OFF switch is used to provide hook signaling to a Vega dispatch console or C­Soft application. When OFF, SELECT audio is routed from the headset to the speaker. When
using a desk microphone the switch should be in the OFF position.

2.2.6 Radio Rx Mute w/PTT – Version 2.1 or Higher

With the release of software Version 2.1, the Windows ® HyperTerminal application may be used
to set, as a programmable option, if radio Rx is muted with PTT. Usually, the radio Rx is muted
when the radio PTT is active. However, full duplex and cell phone Direct Connect applications
require audio (i.e. go ahead tones) to be heard by the user after PTT is pressed.
With the PC connected to the HB3Plus and HyperTerminal running, press “M” on the PC
keyboard. The HB3Plus will respond with “MUTE RADIO RX WITH PTT [Y/N]” as shown in
Figure 3.
