1. Introduction

The model C-6124 is a unique multi-channel, multi-format, and self-contained desktop radio control console.

Choosing one of the following may configure a channel:

TLM -a dedicated two or four wire sequential-tone or E&M relay closure radio control line module.

PLM -a full duplex conventional PSTN telephone or a jumper selectable dial-up access radio control line module.

NOTES: 1-Upon Power-up, no lines are Selected or Unselected. 2-A module will not function if it has not been

preprogrammed. (Refer to the programming instructions on page 22).

A desk microphone (or gooseneck microphone) may be installed for operation along with a handset (or headset) as

indicated on the back of the UIM module. When a PTT occurs from either of the two microphones, the other will mute

so as not to pick-up unnecessary ambient noise during transmission.

When the handset is taken off hook and a line is Selected, the receive audio from that line is transferred to the

earpiece.

Any combination of line cards may be obtained by simply installing the appropriate card into the desired slot. One to

twenty-four cards may be installed, six for every additional switch panel. All pushbuttons and indicators on the

touchscreen display are under software control and may be customized to look exactly as the user specifies

(customized at factory for additional charge). This flexible approach provides the user full remote control of the

required functions of a two-way radio system while allowing for future expansion or system changes.

The C-6124 sports a backlit LCD touchscreen and a unique enclosure that allows the operator to tilt the console to

the operator's desired viewingangle. This feature allows a more flexible dispatch environment in which the console

may be installed. The dispatcher can easily operate the console while sitting or standing as well as watching the

status of the console from across the room.

2. Hardware Overview

The C-6124 is a multi-line, multi-mode console designed specifically for growth in system requirements. The console

is based on a modular design utilizing multi-processor architecture for maximum flexibility. The system allows for

customization through software and expandability through common hardware.

The User Interface Module (UIM) is the central processor handling the user interface, common controls, touch screen

display, Selected speaker and VU meter, as well as keeping track of the activities of the Selected line.

The Switch Bus Module (SBM) accepts up to six plug-in individual line cards via common audio and data busses. Up

to three SBM’s can be added to the C-6124.

The End Bus Module (EBM) houses the Unselect audio amp and the last six line card slots.

2.1 User Interface Module (UIM)

The UIM consists of the following eight sub-assemblies: power supply, VU meter PCB, crosspatch switch PCB, voice

delay PCB, UIM digital and analog PCB’s, LCD display and touch screen. The central processor is mounted on the

UIM digital PCB. It monitors and controls the activities of the console with respect to the console operator. The

touch screen display is constantly being monitored for activity from the operator while providing instructional

information and feedback. The UIM digital PCB monitors the data bus for line Select while providing PTT, telephone

dialing, and handset hook data to the line cards. All programming functions are accessed through the data bus from

information entered on the touch screen display when in programming mode. All audio is processed on the UIM

analog PCB, this includes TX (microphone), Select and Unselect Speaker and Crosspatch busses. TX audio is

processed and routed to the audio bus while the receive audio is routed to the appropriate speaker power amplifier or

the handset/headset earpiece. The earpiece level is internally adjusted to a comfortable listening level and is not

affected by the speaker volume control. The microphone sensitivity as well as the display contrast may also be

adjusted internally.

2.2 Switch Bus Module (SBM)

The SBM is mounted between the UIM and EBM and is interfaced to the UIM analog PCB through a ribbon cable

connecting the microphone audio, Select audio, Unselect audio, crosspatch and the data busses together. This entire

bus interface is then branched out to the connectors to which the individual line cards are installed. When a line card

is installed onto the SBM, the four switches, associated indicators and the Unselectvolume control for that line

position electrically become part of the line card and are under full control of the card's software. The Unselect

The console consists of three assemblies.

volume controls can be independently adjusted for a minimum level if desired. Up to six line cards can be installed on

each SBM.

2.3 End Bus Module (EBM)

The EBM is the last module of the console and houses both the Unselect speaker amplifier and the last six line card

slots.

2.4 Tone Line Module (TLM)

The TLM is a radio control card using either the standard tone control format compatible with Motorola and

Ericsson/GE or E&M relay closure. The line card may be hardware configured for either two-wire or four-wire

operation and may be factory modified to accommodate non-industry standard tone control formats if desired. The

TLM contains a tunable notch filter at the switched transmit audio input, so as not to talk-off the PTT tone when the

microphone is active. This audio is followed by a summing amplifier, where the PTT tone sequence and the DTMF

encoder are added. This combined audio is fed into the line driver amplifier, which drives a balanced interface to the

tone line at the appropriate levels. The receive audio is taken off the balanced tone line, amplified and processed,

then fed into the notch filter, and the DTMF decoder. The line activity detection circuit is branched off at the first

amplifier providing both status signals to the processor as well as a control signal for the line inactivity squelch. The

filtered audio is then switched into either the Selected or monitored audio busses. (Refer to 3.4 page 9 for

functionality).

2.5 Phone Line/Dial-up Modules (PLM/DLM)

The PLM is physically identical to the DLM. The only difference is a jumper position.

The telephone card has identical audio filtering and switching circuits as the TLM except for the interface to the

telephone line. A self-contained hybrid module houses the necessary circuitry to provide TX/RX audio isolation, off

hook enable and ring detect.

The DLM is the dial-up remote card intended to controla remote radio using Vega's Dial-up tone control format

(compatible with Vega Models C-550/RP-250 or RP-251).

The telephone interface is fully FCC and DOC approved. (Refer to 3.5 and 3.6 page 11 & 12 for functionality)

3. Controls and Indicators

3.1 Front Panel

For a description of these controls and indicators please see the following pages.

A self-adhesive label is supplied with each SBM. You can place it above the Select switch pushbuttons. Trim to fit

and print the appropriate information on the strip of paper that slides into the clear plastic holder.

A desk microphone (or gooseneck microphone) may be installed for operation along with a handset (or headset) as

indicated on the back of the UIM module. When a PTT occurs from either of the two microphones, the other will mute

so as not to pick-up unnecessary ambient noise during transmission. Note that, in dual microphone configurations,

the desk microphone is the default microphone. The dedicated PTT button on the handset or headset must be

pressed to use the handset/headset. This is true in all cases except during telephone operation in which the

handset/headset becomes dedicated to the telephone call. In the case of a telephone call, pressing the PTT

bar/button on the handset/headset will place the phone call on hold and transmit microphone audio over the radio.

NOTE: A PLM/DLM (telephone line module/Dial up line module) requires using a telephone headset or a handset for

operation. You cannot operate them if you are only using a desk microphone or gooseneck microphone; audio feed

back would occur making conversation unintelligible. They will go off hook, but the RX audio will go nowhere.
