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).

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 contr ol 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 viewing angle. 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 console consists of three assemblies.

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.

User Interface Module (UIM)

Switch/Bus Module (SBM)

End Bus Module (EBM)

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, cr osspatch 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 Unselect volume control for that line position electrically become part of the line card and are under full control of the card's software. The Unselect

3 Vega’s C6124

volume controls can be independently adjusted for a minimum level if desired. Up to six line cards can be instal led 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 control a 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)

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 occur s 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 ar e 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.

3.2 Common Controls and Indicators

Select Volume Control: Adjusts the speaker level of the Selected audio. A minimum volume level can be preset on the speaker card so that the console operator can not turn the volume to zero.

Unselect Volume Control: Adjusts the speaker level of the Unselected audio. A minimum volume level can be preset on the speaker card so that the console operator can not turn the volume to zero.

Handset, Hookswitch, and PTT: When you pick the handset off the cradle, receive audio from any line is the Select mode line is transferred to the earpiece and the microphone mouthpiece becomes active. Unselect audio remains on the Unselect speaker. The exception to this is when a phone call is active. Phone audio will go to the handset earpiece and Select audio will revert back to the Select speaker until the phone call is done. During the phone call the operator monitors the Select lines on the Select speaker. If attention must be given to the radio side the operator need only press the PTT button and microphone audio will be routed to the Select line radios. Releasing the PTT will transfer microphone audio back to the phone conversation. The phone call is effectively put on hold during radio transmission and will not be able to monitor the operators radio traffic.

Touchscreen Display: This interface assists the console operator by providing current status of the console and instructional information. See the following pages for touchscreen examples.

In the operational mode, the liquid crystal display shows the full name of the currently Selected line and associated function tone. If a line is not Selected, the display will show "no Selection.” If the PTT is pressed without a line Selected, the console will beep and "no selection" will flash.

The main screen displays soft-key access to such features as Group Select, Simulcast, Timed Mute, Crosspatch, Frequency selection, CTCSS Monitor, and Intercom. The console operator can also Select any of the 16 preprogrammed telephone numbers as well as manually dialing numbers to access dial -up base stations connected to the system.

Configuration of the programmable Console features is also done through the touchscreen display. The touchsensitive screen will always beep when touched, providing feedback to the user.

VU Meter: Displays Selected receive and Microphone audio bus levels. PTT Pushbutton: When pressed all Selected lines will transmit. Crosspatch Controls: Select Pushbutton: When Selected and held down you can add any combination of lines to a crosspatch

group by pressing their Select pushbutton. Block Pushbutton: When pressed will mute the line that is controlling the crosspatch until another line

takes control of the crosspatch group. This is to provide control over excessively long one-sided conversations. To deselect a line from a crosspatched group, all you need to do is press the release pushbutton on the corresponding line.

PTT Pushbutton: When pressed this pushbutton transmits console operator microphone audio to all cards

in the crosspatch group.

The GRPSEL button is a toggle ON/OFF button which disables the 1ofN functionality of the console. When the GRPSEL button is illuminated the operator is able to set up a Simul -group of as many cards as is desired. To activate the Group Select mode the operator presses the GRPSEL button. The button will illuminate. As long as the button is illuminated the operator may add or delete lines to the group. Dial -up lines must have an active call to be included in a group. When the operator is finished setting up the Sim ul-group the operator presses the GRPSEL button again to revert back to the 1ofN mode.

The lines are allowed in a group are restricted by the TX Block settings set in System programming mode. In the example where line 1 blocks lines 2 and 3 the operator m ay include 2 and 3 in the group only if line 1 is not part of the group. If line 1 is included in the group the console will not allow lines 2 and 3 to be added. If line 2 or 3 are already in the group when line 1 is Selected line 1 will be included in the group, but lines 2 and 3 will drop out.

The XPATCH button will transfer the user to a preprogrammed crosspatch group select screen. From this screen one of eight preprogrammed groups may be selected.

RX ALL (Receive All): Push to monitor all lines that are not in the Select mode. Any line that is in the Select mode

will automatically become part of the Unselect group when it is taken out of Select mode.

TX ALL (Transmit All) : This feature gives the user a convenient means of Selecting all lines for Simul-transmissions without having to group select one at a time. As in group select, if a dial -up line is to be included in this feature, the line must already be dialed-up.

To initiate Simulcast, momentarily touch the "TX ALL" on the display. The line description will change to "Group Select Mode", and all available lines will automatically be Selected.

To disengage Simulcast, simply Select a single line in the usual manner. The TX ALL function will not include any line which TX Blocks any other line. For example, If line 1 TX Blocks lines

2 and 3 a TX ALL command will include lines 2 and 3, but not line 1 (assuming lines 2 and 3 do not TX Block any other card.

CTCSS MONITOR: When touched momentarily, this featur e causes the Selected base station with a CTCSS decoder to momentarily unmute so that the dispatcher may monitor for activity on the air.

This reduces the possibility of accidentally interfering with other users on the channel who may be using a different CTCSS tone. This capability is required by FCC regulations.

TIMED MUTE : When touched, TIMED MUTE mutes all "Unselected" audio for fifteen seconds. This feature is useful when the dispatcher wishes to concentrate on the Selected channel without interference from the other lines. The mute time is programmable up to 59 seconds. The programming is done in the System programming menu

17 Vega’s C6124

SIMUL GROUP: The group select key allows the user to Select multiple lines for simultaneous transmissions. If dial -

up lines are to be included in the group select, they must first be dialed-up and on hold. To engage group select, press SIMUL GROUP on the display, this takes you to another screen (Figure 4.3). To

initiate one of the preprogrammed groups, simply press the corresponding number on the screen. To manually Select a group, press and hold the manual select button and then Select each line for the group setup.

The lines allowed in a group are restricted by the TX Block settings set in System programming mode. In the example where line 1 blocks lines 2 and 3 the operator may include 2 and 3 in the group only if line 1 is not part of the group. If line 1 is included in the group the console will not allow lines 2 and 3 to be added. If lines 2 or 3 are already in the group when line 1 is Selected line 1 will be included in the group, but lines 2 and 3 will drop out.

To add lines IDs to the crosspatch group press on the corresponding number on the screen. The number will invert. To drop a line ID off the group press the inverted ID number and it will drop out of the group. In the example screen above line IDs 1, 5 and 8 are part of the crosspatch group. When the configuration is as is desired press the SAVE button.

When programming is complete press the << button to return to MENU 2. It is suggested that all TX Blocks be setup before the crosspatch groups are set up. When a TX Block is set up the C-6124 will edit crosspatch groups to drop out violations. When programming crosspatch groups the C-6124 will not let you violate existing TX Blocks.

IMPORTANT: ALL LINE CARDS MUST HAVE BEEN PROGRAMMED WITH A UNIQUE ID NUMBER FOR THE C-6124 TO FUNCTION PROPERLY.

PARALLEL CROSSPATCH NOTIFICATION: The C-6124 has an option that uses DTMF characters “A” and “B” to communicate to parallel consoles that a crosspatch has been set up. When this option is enabled DTMF “A plus *”characters will be sent out on the lines that are placed in a crosspatch. Parallel consoles will decode this “A plus *” and disable their respective line cards. This ensures that parallel consoles will not interfere with the complex tone signaling that is required in a crosspatch situation. A DTMF “B” will tell parallel consoles that a particular line has been removed from the crosspatch and may be used in standard operations. Note that this option must be OFF if the communications system uses the DTMF alpha digits. To turn this option OFF or ON press the button which displays the current condition.

MUTE TIME OUT: When the MUTE button on the front touchscreen is pressed, the Unselect speaker will mute for a specific amount of time and then the speaker will revert to normal activity. This amount of time is programmable from 0 to 99 seconds. Press the UP and DOWN buttons until the proper time is displayed.

The C-6124 allows the user to modifiy the parameters of the function tones in two ways:

1) Function Tone Range – The user may decide between offering only four function tones or offering a full complement of 12 function tones. If the F1-F4 setting is selected the arrow button on the main operational screen which sends the operator to the F1-F12 screen will be eliminated. This will effectively leave only four function tones at the operators disposal.

2) F3/F4 Frequencies – The standard frequencies for F3 and F4 are 1750Hz and 1650Hz repectively. Alternate formats use 1350Hz and 1250Hz . The button for the current setting will be inverted. Press the setting desired.

The RX Block feature allows the technician to set up groups of lines which will mute their RX audio when a certain line is transmitting. In the above example, line 4 has been programmed to RX Block lines 1,3, and 5 when line 4 is in the PTT condition. This is a one way effect. Transmitting over line 1 will not mute any of the other lines. For this to occur, line 1 must be programmed to RX Block line 4. Note that an RX Blocked line will not be allowed in a crosspatch with the line that blocks it.

To program an RX Block group get to the RX Block programming screen as shown in the steps above. When prompted to Select a line for programming press the Select button of the card to be programmed. The previous program will appear. You may then add or subtract any number of lines to the group. When completed, press the SAVE button.

LINE INFORMATION Screen (TLM)

The above screen representation describes the parameters that may be programmed on the Tone Line Module (TLM).

CARD ID NUMBER: Each card must have a unique ID number. The ID number may by any number between, and including, 01 and 24. This number is used to identify the card to the software. In the above case the card ID is 05. Each ID must have two digits. If the card ID is 00 then the card is disabled. Each card is shipped from the factory with an ID of 00. Spare cards may be installed in the console and programmed with the ID of 00. They will lie inactive until they are programmed with an ID number between 01 and 24.

Card description: This card has the label MT. WILSON. Whenever this card is Selected (and is the only card Selected) the label MT. WILSON will appear on the main screen.

Card type: There are three types of cards – DEDICATED, TELEPHONE, and DIAL-UP. The TLM is considered a dedicated line. This field is used in programming mode only to identify the card. This is done to avoid having the programmer go to the back of the console to identify each card.

SELCALL: The TLM contains a DTMF select call function. This allows a mobile unit to call a specific card using a four-digit DTMF code. When this DTMF code is received by the TLM, the TLM will blink its red SELECT light and send a beep to the Unselect speaker. The beeping and flashing is reset under one of two conditions. The first is when the console operator presses the SELECT button of the TLM that has received the call. The second is when the AUTO RESET feature is enabled and a parallel console sends a PTT tone burst indicating that the parallel console is answering the call. Note: It is not a requirement that all parallel TLM’s be programmed with the same select call. In the above case a DTMF string of 1234 would activate the select call routine.

AUTO RESET: When a valid select call is decoded, visual and audio indication is given. When two parallel consoles are programmed with the same select call code, they both will flash and beep. When AUTO RESET is enabled, the flashing and beeping will stop if a parallel console transmits or if the Select button on the particular TLM is pressed. When AUTO RESET is disabled, the flashing and beeping can be stopped only by pressing the Select button on each TLM of each console.

AUTO RESET

37 Vega’s C6124

CROSSMUTE ENCODE/DECODE: The C-6124 has an audio Crossmute feature. This feature sends a DTMF digit before and after each transmission. Parallel consoles decode this DTMF and remove that line’s audio from their speaker outputs. This feature allows console operators in the same room to operate without a feedback loop occurring. The programmer may independently enable or disable both the encoding of the DTMF signal and the decoding of the DTMF signal. For example, in a room with three consoles in parallel all three will have their CROSSMUTE ENCODE and DECODE set to ON. The console in the next room, which is tied in parallel, is in no danger of audio feedback; therefore, both of the CROSSMUTE attributes are set to OFF. Note that this feature uses DTMF digits “C” and “D”. If it is possible for these digits to be used in the system, disable the tone Crossmute feature or problems will occur. A hardwire Crossmute is offered through each TLM modular connector as an alternative.

LAM FLASH: Each TLM has a programmable Line Activity Monitor (LAM) flash setting. This may be programmed from 0 to 9 seconds. This is the length of time that the LAM light on the front panel will blink after the squelch gates block the receive audio.

CROSSMUTE Programming

Crossmute is used when more than one console is in audio range of each other. Transmitting on a line that a parallel console is monitoring will produce audio feedback. The Crossmute feature prevents the line card of a parallel console from driving the Unselect audio bus. This action takes that audio off the console speaker. The C-6124 offers two methods of crossmuting lines. The first is a hardwire option that is available from the modular connector at the back of each TLM. The second method is through use of the “C” and “D” DTMF characters. This second method is enabled and disabled by following the screen progression shown above. In the tone-based crossmute a DTMF “C” is transmitted before the burst tone and audio. A DTMF “D” is transmitted when transmission has stopped. This is a convenient method if the letter DTMF digits are not used anywhere in the system. The encoding and decoding of this feature are independently enabled or disabled by pressing the button to the right of the text, which describes the parameter. The ON and OFF text in the button give the present status. When the setting is as desired, press the << button to return to the LINE PROGRAMMING screen.

6. TLM Description

6.1 INTRODUCTION/DEFAULTS

The Tone Line Module (TLM) for the C-6124 system provides communication with any standard tone

remote system . The TLM is shipped from the factory in the following state: 2 Wire mode 600 ohm output impedance Squelch control enabled Crossmute disabled

6.2 INPUT/OUTPUT

Two jacks are available for external access. The recorder jack is a 3.5mm female plug. The line jack is an RJ-

45 eight pin modular jack.

6.2.1 LINE JACK The line interface of the TLM is an eight pin modular connector. A six -foot cable is included with each card for use as is appropriate. The connector pins are assigned as follows:

PIN DESCRIPTION 1 Crossmute output 2 E&M pole (local control) 3 4Wire RX high 4 4Wire TX high; 2Wire high 5 4Wire TX low; 2Wire low 6 4Wire RX low 7 E&M throw (local control) 8 Ground

Pin 8 is the pin closest to the bottom of the card when the card is installed in a console.

6.2.2 RECORDER OUTPUT The recorder jack is a 3.5 mm female audio jack. This output provides both transmit and receive audio as heard by the single TLM. The output is 600 ohm balanced. The receive path audio is always included in the recorder output. Two jumper selections allow the user to select if the transmit side contains tones and if crosspatch transmit audio is to be included. See section 6.3.5 for a complete description.

6.2.3 MULTIPLE CONSOLES / PARALLEL OPERATION TLM’s are designed to operate in parallel with other consoles, refer to sections 6.3.3 and 6.3.4 for correct jumper settings.

Remote Control Console 48

6.3 FEATURE DESCRIPTION

6.3.1 CROSSMUTE The Crossmute function provides muting of the receive audio paths on consoles in the same room as a transmitting console. This is to prevent audio feedback. Audio feedback occurs when the microphone audio from one console appears on the speaker of a parallel console in the same room. If the speaker is within audio distance of the microphone an audio loop will be formed and a loud squeal will be produced on the speaker. TLM’s offer both logic level and tone based Crossmute schemes. In the Logic Crossmute a wire connection is made between each of the consoles to be crossmuted. This method allow s different makes and models of consoles to be integrated into the same system. The tone based Crossmute uses DTMF tones before and after the transmission. This method has the advantage that no wiring must be made. It has the disadvantage that parallel consoles hear the DTMF beep. Note that the tone based Crossmute uses DTMF digits in the A through D range. These must not be used for signaling in a system using tone based Crossmute. Logic and tone based Crossmute functions are independent of each other. Either one, both, or neither may be used.

6.3.1.1 LOGIC CROSSMUTE

Feedback may be avoided by muting the receive audio of the line card which is in parallel with a transmitting line card. This may be accomplished by connecting pins 1 and 8 of each of the consoles to be crossmuted as shown above. Pin 8 must be connected to provide a common ground. The figure shown illustrates a

Console 2: TLM 1

Console 3: TLM 1

setup where consoles 1 through 3 are in the same room and, when one transmits, the others will mute the receive audio from that one line. Console 4 is offsite with no possibility of feedback, and, therefore, is not hardware crossmuted. Note: The intercom function will not work between crossmuted consoles. Logic Crossmute is enabled and disabled by JP6 on the TLM card. To enable logic Crossmute place JP6 in the A position. To disable logic Crossmute place JP6 in the B position. JP6 is checked by the microprocessor on power up. Any changes after power up will not be registered.

6.3.1.2 TONE BASED CROSSMUTE

A second method of crossmuting consoles is the tone method. In the tone based crossmute a DTMF “C plus *” characters are transmitted before each transmission and a DTMF “D” character is transmitted at the end of each transmission. To use this feature the system administr ator must make sure these digits are not used elsewhere in the system as muting may occur when these digits are decoded at the TLM. Tone based crossmuting may be independently enabled and disabled on the touchscreen in the lineprogramming mode. See the Programming manual for instructions on how to enable and disable the tone based crossmute.

6.3.2 E&M RELAY CONTACT CLOSURE/ LOCAL CONTROL The TLM provides a dry contact closure during PTT functions between pins 2 and 7 of the line jack. The relay closur e can carry 500mA at 12VDC or 250mA at 115VAC. The relay is not activated during intercom functions. The relay is normally open. If this relay closure is used for local control (or any other case where tone bursts are not used for signaling) moving JP7 to the B position may disable the tone burst generator.

6.3.3 FOUR WIRE MODE Each TLM comes standard with a jumper selectable 2 or 4 wire option. Note: The TLM is shipped in the 2wire mode. 4-wire mode is accomplished by the following jumper positions:

Jumper Position JP10 B JP11 B

The RX pair is now on pins 3 and 6 of the line jack and the TX pair is on pins 4 and 5. Once the transmit and receive paths are separated the impedance of each side must be set.

The RX side is jumper selectable for a 600 ohm impedance or 10k ohm impedance. If only one TLM is on the line (no parallel consoles) then place JP12 in the A position for a 600 ohm line impedance. If more than one TLM’s are on one line then place JP12 on one console in the A position and all other consoles in the B position. Each console added to the system will result in line loss. The following chart gives an indication as to how much loss can be expected. The first console in the system is set for an impedance of 600 ohms out (approximately). Each console added to the system there after is set with an impedance of 10k ohms. As the chart shows, the more consoles that are added, the lower the line impedance and the greater the loss in audio level . JP12 individual total line line Console added position impedance impedance loss (db) 1 A 584 584 0 2 B 10k 552 -.48 3 B 10k 523 -.95 4 B 10k 497 -1.4 5 B 10k 473 -1.8 6 B 10k 452 -2.2

See the section on level adjustments to make up for any loss incurred.

2-WIRE Operation:

/In 2-wire operation JP12 should be in the B position for 10K ohm line impedance.

6.3.3.2 TX SIDE SETTINGS

Two jumpers on the transmit pair allow a degree of control over the output impedance. The following chart lists the jumper positions for each card depending on how many consoles are placed in parallel. All cards should have the same jumper settings.

Consoles in TLM TLM Individual TLM Parallel JP8 JP9 Output Impedance 1 B A 600 ohms 2 A A 1200 ohms 3 B B 1800 ohms 4 A B 2400 ohms

6.3.3.3 TRANSMIT MONITOR

In a 4 wire system the transmit line may be monitored by the receive circuits by placing JP1 in the B position. See section 6.4.24 for information on adjusting the monitor level.

Remote Control Console 50

6.3.4 TWO WIRE MODE In two-wire mode only the two inner pins (pins 4 and 5) of the line jack are used. These two pins handle both transmit and receive audios. Note: The TLM is shipped from the factory in 4-wire mode. To enter 2wire mode the following jumper settings must be present:

Jumper Position Description JP10 A 2/4 wire selection JP11 A 2/4 wire selection JP12 B Places the RX side in high impedance state JP1 A Disable TX monitor

When putting consoles in parallel the receive side al ways remains in the high impedance state (JP12 = B). The transmit side follows the same settings as in 4 wire mode.

Consoles in TLM TLM Individual TLM Parallel JP8 JP9 Output Impedance 1 B A 600 ohms 2 A A 1200 ohms 3 B B 1800 ohms 4 A B 2400 ohms

The transmit monitor is not needed in 2 wire mode as the transmit audio is already on the receive circuit. JP1 is placed in the A position to disable the TX monitor.

6.3.5 RECORDER OUTPUT Receive audio to the recorder is taken after the notch filter and is gated so that audio will be presented to the recorder only when valid receive audio is present. For example, transmit audio is present on the receive circuits in a transmit condition. The gate will block any audio on the receive path from the recorder in a Transmit condition. Transmit audio may be recorded in two states – with or without tones. If jumper JP14 is in the A position only audio from the microphone circuit is recorded. This includes microphone audio and any auxiliary audio inserted at the UIM rear panel through the plug-in terminal blocks. If JP14 is in the B position all of the control tones are included in the recording. This option exists for the system operator to be able to debug a system problem. The system operator will be able to verify which control signal came from the C-6124 console. In this position crosspatch transmit audio will be recorded, as well. If JP14 is in the B position then JP15 should be moved to the B position to avoid having crosspatch tr ansmit audio summed in twice. Crosspatch transmit audio may be included with the recording by placing JP15 in the A position. This jumper is moved to the B position when JP14 is moved to the B position.

6.3.6 SQUELCH CONTROL Squelch control allows the system operator to set up the receive path so the receive bus will not be driven unless there is a minimum audio level on the receive path. The squelch control disables this audio gate until the LAM circuitry activates. The receive gate will allow RX audi o through only as long as the audio maintains a minimum audio level as judged by the LAM circuit. There are three receive audio paths – Select, Unselect, and Crosspatch RX. Each may be configured with squelch control independently.

6.4 LEVEL ADJUSTMENTS

The above figur e shows a top view and side view of the TLM card with the adjustment points labeled. The side view is the view one would have if the back cover of either the Switch Bus Module (SBM) or the End Bus Module (EBM) were removed for card adjustments. The potentiometers that are most likely to be adjusted are available without taking the card out of the chassis.

6.4.1 TRANSMIT SIDE ADJUSTMENTS The transmit side audio is a summation of four different audio sources – microphone audio, crosspatch audio, single tones, and DTMF tones. The following is a list of the potentiometers that affect the transmit path. The “Access” field identifies the potentiometers as one that is internal or external. An external adjustment is one that can be accessed by just taking the back panel off. An internal adjustment requires that the card be pulled out of the console to be adjusted. For internal adjustments it is recommended that an extender card be purchased from the factory.

6.4.1.1 MICROPHONE AUDIO

RV7 adjusts the level of microphone audio that is summed with the other four transmit audio sources. This potentiometer should be adjusted only when microphone audio must be changed relative to the hold tone output. In otherwords, use this potenti ometer only to bring microphone levels to a predetermined level above the hold tone. Use RV4 (See 4.1.3) to increase audio levels to the remote site. At the factory, this potentiometer is set so that a 700mV input to the TLM card from the Switch Bus Module produces a signal that is 20db higher than the 2175hz hold tone at TP7.

6.4.1.2 CROSSPATCH TRANSMIT AUDIO

RV8 adjusts the level of microphone audio that is summed with the other four transmit audio sources. This potentiometer should be adjusted only when the crosspatch transmit audio must be changed relative to the hold tone output. In otherwords, use this potentiometer only to bring crosspatch transmit levels to a predetermined level above the hold tone. Use RV4 (See 4.1.3) to increase audio levels to the remote site. At the factory, this potentiometer is set so that a 700mV input to the TLM card from the Switch Bus Module produces a signal that is 20db higher than the 2175hz hold tone at TP7.

6.4.1.3 TRANSMIT DRIVER

RV4 controls the output level of the TLM. This level is accessible from the back and, in most cases, is the only potentiometer in the transmit path that need be adjusted to obtain proper system levels.

6.4.1.4 TONE OUTPUT

This potentiometer is for fine adjusting the tone output level. Be very cautious when engaging in this adjustment as that all transmit levels are shipped relative to the tone output.

6.4.1.5 NOTCH ADJUSTMENTS

The notch filter is designed for a center frequency of 2175Hz. TLM cards are shipped from the factory set at a 2175Hz notch. The notch adjustments are then “potted” with a compound so the potentiometer will not change value. The notch circuit should be adjusted only if a different notch frequency is desired. Adjustments are designed into the circuitry in the first place so that the factory can compensate for component tolerances. To adjust the notch filter, insert the desired notch tone to the aux. audio input on the plug-in terminal blocks at the rear of the UIM (the unit that holds the touchscreen). The input level should be as high as possible without measuring clipping at TP3 on the TLM. Adjust RV10 for the greatest amplitude at U16.8. Next adjust RV11 for the smallest amplitude at TP6. Make fine adjustments to both RV10 and RV11 for the lowest possib le amplitude signal at TP6.

6.4.1.6 DTMF OUTPUT LEVEL

Potentiometer RV15 controls the output level of the DTMF on the TLM. At the highest level DTMF will transmit around 0.975V at the summing point tested by TP7.

6.4.2 RECEIVE SIDE ADJUSTMENTS The receive circuitry processes the receive audio and distributes it to the proper circuitry for analysis. The audio coming in the receive side is fed to a Line Activity Monitor (LAM), DTMF decoder, Parallel transmit detect, recorder, and the Select/Unselect/Xpatch RX busses. The following chart lists the potentiometers in the receive path.

Reference Access Description RV1 external Line input gain adjustment RV2 external TX monitor level (for 4 wire mode) RV5 internal ALC knee of compression adjust RV9 external LAM active level RV3 internal Bus output level RV14 external Recorder output level RV12 internal Notch frequency phase control RV13 internal Notch frequency adjust

53 Vega’s C6124

6.4.2.1 RECEIVE INPUT LEVEL

RV1 adjusts the gain of the input amp directly off the line. RV1 offers a gain range of +13db to –50db. The resulting audio from this amp stage is fed into the LAM circuit and the Automatic Level Control (ALC) circuit.

6.4.2.2 AUTOMATIC LEVEL CONTROL (ALC)

The receive side audio path has an ALC circuit. The knee of compression is set by adjusting RV5 and measuring at TP4. The maximum output of the ALC circuit is set at 0.775V. When the signal at TP4 is around 0.775V the circuit is in compression. The knee of compression starts at about 0.588V at TP4.

6.4.2.3 LINE ACTIVITY MONITOR (LAM)

RV9 sets the level at which the LAM light on the Switch Bus Module activates. The LAM light is the green LED in the Unselect button. It will blink when a minimum signal level is detected. This parameter may be set by adjusting RV1 to its desired location (See 4.2.1) and then inserting a signal at the minimum detect level. If the LAM light is on, adjust RV9 counterclockwise until the LAM light goes off. Carefully turn RV9 clockwise until the LAM light goes on. If the LAM light is off do the same adjustments, but reverse the turn directions.

6.4.2.4 TRANSMIT MONITOR

The transmit monitor provides a portion of the transmit audio to the receive path. This allows the console operator to listen to the transmissions of parallel console operators. To set this level have a parallel console operator intercom on the line to be set. Adjust RV2 until the level is comfortable in the handset/headset earpiece or the speaker.

6.4.2.5 BUS OUTPUT LEVEL

RV3 controls the output level to the internal bus. The factory sets this level for 770mv at TP11 for a 600mv signal at TP9.

6.4.2.6 RECORDER OUTPUT

Adjust RV14 until the desired output level is reached at the recorder jack.

6.4.2.7 NOTCH ADJUSTMENTS

The notch filter is designed for a center frequency of 2175Hz. TLM cards are shipped from the factory set at a 2175Hz notch. The notch adjustments are then “potted” with a compound so the potentiometer will not change value. The notch circuit should be adjusted only if a different notch frequency is desired. Adjustments are designed into the circuitry in the first place so that the factory can compensate for component tolerances. To adjust the notch filter insert the desired notch tone on the RX pair of the line jack. The input level should be as high as possible without measuring clipping at TP4 on the TLM. Adjust RV13 for the greatest amplitude at U8.8. Next adjust RV12 for the smallest amplitude at TP2. Make fine adjustments to both RV13 and RV12 for the lowest possible amplitude signal at TP2.

7. PLM Description

7.1 INTRODUCTION/DEFAULTS

The Phone Line Module (PLM) for the C-6124 system provides telephone communication over a PSTN line.

7.2 INPUT/OUTPUT

Two jacks are available for external access. The recorder jack is a 3.5mm female plug. The line jack is an FCC approved RJ-11 standard modular jack.

7.2.1 LINE JACK The line interface of the PLM is a four -position/two conductor modular connector. A six-foot cable is included with each card for use as is appropriate.

7.2.2 RECORDER OUTPUT The recorder jack is a 3.5 mm female audio jack. This output provides both transmit and receive audio as heard by the single PLM. The output is 600 ohm balanced. The receive path audio is always included in the recorder output. Two jumper selections allow the user to select if the transmit side contains tones and if crosspatch transmit audio is to be included. See section 7.3.3 for a complete description.

7.3 STANDARD OPERATION

Two modes of operation are available with the PLM/DLM. The first is as a standard telephone card and the second is as a dial -up line.

7.3.1 PHONE LINE MODULE (PLM) Placing JP1 in the B position configures the card for telephone mode. In this configuration, the card will act as a standard telephone.

7.3.2 DIAL-UP LINE MODULE (DLM) Placing JP1 in the A position configures the card to act as a dial -up module. JP7 must be in the A position. This introduces control tones into the system, which are used by a remote adapter to directly interface with a radio. This mode allows remote radio control without having to lease a line. This mode requires a Vega RP-251 remote adapter panel to work with. A positive keying tone gives security against outsiders calling the remote number by mistake.

7.3.3 RECORDER OUTPUT Receive audio to the recorder is taken after the receive notch filter. This removes any keying tones that may be present during DLM mode. As the hybrid isolation is not high, transmit audio is present in the receive path as well. Because of this, both the receive and transmit audios may be recorded using just the receive path. JP14 and JP15 are added for test purposes. Since all audio is found on the receive path neither of the transmit audio paths available should be summed into the recorder circuit. The jumper plug for JP14 should be removed and JP15 should be in the B position.

7.3.4 SQUELCH CONTROL (DLM mode only) Squelch control allows the system operator to set up the receive path so the receive bus will not be driven unless there is a minimum audio level on the receive path. The squelch control disables the audio gates until the LAM circuitry activates. The receive gate will allow RX audio through only as long as the audio maintains a minimum audio level as judged by the LAM circuit. There are three receive audio paths – Select, Unselect, and Crosspatch RX. Each may be configured with squelch control independently.

7.3.5 PARALLEL LINE OFF-HOOK The green LED in the Instant PTT switch on the front panel of the Switch Bus Module will light when a parallel line is off-hook. PSTN lines usually stay at –48VDC when on-hook. During the off-hook condition the line voltage will drop to about –10VDC. The Parallel off-hook detector will activate when this line voltage is less than –25VDC. If the PLM is connected to a PABX which works off a lower voltage (-24VDC typical) the parallel line detect will stay lit.

7.4.1.1 MICROPHONE AUDIO

RV2 adjusts the level of microphone audio that is summed with the other four transmit audio sources. In DLM mode, this potentiometer should be adjusted only when microphone audio must be changed relative to the hold tone output. In other words, use this potentiometer only to bring microphone levels a predetermined level above the hold tone. Use RV4 (See 4.1.3) to increase audio levels to the remote site. At the factory, this potentiometer is set so that a 700mV input to the PLM card from the Switch Bus Module produces a signal that is 20db higher than the 2174Hz hold tone at TP7.

7.4.1.2 CROSSPATCH TRANSMIT AUDIO

RV8 adjusts the level of microphone audio that is summed with the other four transmit audio sources. In DLM mode, this potentiometer should be adjusted only when the crosspatch transmit audio must be changed relative to the hold tone output. In other words, use this potentiometer only to bring crosspatch transmit levels a predetermined level above the hold tone. Use RV4 (See 4.1.3) to increase audio levels to the remote site.

7.4.1.3 TRANSMIT DRIVER

RV4 controls the output level of the PLM. This level is accessible from the back and, in most cases, is the only potentiometer in the transmit path that need be adjusted to obtain proper system levels. When adjusting system levels make sure that the DTMF level out is high enough to properly dial the Phone Company. RV4 must be adjusted to the point where dialing out is possible. Once dialing out is established use a combination between RV2 (4.1.1) and RV4 to set voice level.

7.4.1.4 NOTCH ADJUSTMENTS

The notch filter is designed for a center frequency of 2174Hz. PLM cards are shipped from the factory set at a 2174Hz notch.

Reference Access Description RV1 external Line input gain adjustment RV9 external LAM active level RV3 internal Bus output level RV14 external Recorder output level RV12 internal Notch frequency phase control RV13 internal Notch frequency adjust

7.4.2.1 RECEIVE INPUT LEVEL

RV1 adjusts the gain of the input amp directly off the line. RV1 offers a gain range of +34db to –50db. The resulting audio from this amp stage is fed into the LAM circuit and the Automatic Level Control (ALC) circuit. The factory suggests that RV1 be adjusted so that the nominal receive input level is 600mv at TP9. The ALC circuit limits the levels going into it to no greater than 770mv. Setting the input level at TP9 to 600mv gives the audio deviation room before it is limited.

7.4.2.2 LINE ACTIVITY MONITOR (LAM)

RV9 sets the level at which the LAM light on the Switch Bus Module activates. The LAM light is the green LED in the Unselect button. It will blink when a minimum signal level is detected. This param eter may be set by adjusting RV1 to its desired location (See 4.2.1) and then inserting a signal at the minimum detect level (the PLM must be off-hook for this test). If the LAM light is on, adjust RV9 counterclockwise until the LAM light goes off. Caref ully turn RV9 clockwise until the LAM light goes on. If the LAM light is off do the same adjustments, but reverse the turn directions.

7.4.2.3 BUS OUTPUT LEVEL

RV3 controls the output level to the internal bus. The factory sets this level for 770mv at TP11 for a 600mv signal at TP9.

7.4.2.4 RECORDER OUTPUT

Adjust RV14 until the desired output level is reached at the recorder jack.

7.4.2.5 NOTCH ADJUSTMENTS

The notch filter is designed for a center frequency of 2174Hz. PLM cards are shipped from the factory set at a 2174Hz notch.

8. UIM Description

8.1 Introduction

The User Interface Module (UIM) is the module that holds the touchscreen and all the central analog and digital processing. Two main assemblies make up the internal circuitry of the UIM. These two are identified as the UIM Analog and UIM Digital boards.

8.1.1 UIM Digital The UIM Digital contains the digital control circuitry. It is this board that drives the touchscreen and acts as the central data bank for all line cards. This board is mounted to the back of the LCD and touchscreen. The only adjustment on this board is the LCD contrast adjustment. See section 3.6 for more detail.

8.1.2 UIM Analog The UIM Analog board contains all the central analog audio processing. It is the board mounted to the floor of the interior of the UIM.

8.2 Inputs, Outputs, and their Adjustments

NOTE: Unless otherwise specified, all connectors are on the UIM Analog board and

accessible from the outside of the back panel. Unless otherwise specified, all adjustments are on the UIM Analog board.

8.2.1 Internal DC power Internal DC power is supplied by an AC/DC supply which requires 100 to 120VAC at 60hz on the AC plug coming out the back of the UIM. +12VDC, Ground, and Earth Ground come off the power supply (mounted to the interior of the UIM back panel) through a power connector that is plugged into P5 on the UIM Analog board.

8.2.2 External DC power The two position plug-in terminal block TB1, available at the rear of the UIM, allows for a 13.6VDC backup battery. A 24 line C-6124 will require an 8 Amp source. Counting from left to right, pin 1 is the positive voltage input. Pin 2 is ground.

8.2.3 Footswitch The two position plug-in terminal block TB2, available at the rear of the UIM, is for an external PTT source. Counting from left to right, pin 1 is the PTT line and pin 2 is console ground. Shorting these two pins will produce the same effect as if the main Transmit button were pressed.

8.2.4 Auxiliary Inputs The three position plug-in terminal block TB3, available at the rear of the UIM, allows for the input of external audio sources. Jumper JP6 directs this audio to either go through the voice processing paths (position B) or to drive the transmit bus directly (position A). Pin 1 of TB3 is a dedicated auxiliary PTT (AUX_PTT). When the AUX_PTT pin is pulled to ground (pin 2 of TB3) the microphone circuitry of the C6124 is disabled. Only DTMF, the Alert tone, and audio from the Auxiliary audio input (TB3 pin 3) are allowed to drive the transmit audio bus. This allows for the hooking up of external devices such as paging encoders.

8.2.4.1 AUX Voice path

When JP6 is in the A position the AUX audio input will act as a third microphone input. The input is high impedance (33k ohms). The AUX audio will be processed through the Automatic Level Control circuitry which will limit the audio that will drive the transmit bus to 0dbu.

8.2.4.2 AUX Audio path

When JP6 is in the B position the AUX audio input will drive the transmit bus directly. The input is about 770mVrms. The AUX audio input should be adjusted so that the input level is at the desired level relative to the voice audio.

Remote Control Console 64

8.2.5 Recorder Outputs Three recorder outputs are available to the rear of the UIM. Each recorder output is 600 ohms balanced and can be driven to .77V. They are all brought to the six position plug-in terminal strip TB5. Counting from left to right the pin-out is as follows: Pin Description 1 Select high 2 Select low 3 Unselect high 4 Unselect low 5 Crosspatch high 6 Crosspatch low

8.2.5.1 Select Recorder The Select recorder will record all transmit audio and Select receive audio. Jumper JP4 allows the user to sum in Unselect audio, if desired. If JP4 is in the A position Unselect audio will be summed in. If JP4 is in the B position Unselect audio will not be summed in. RV7 controls the overall output level.

8.2.5.2 Unselect Recorder

The Unselect record output contains Unselect audio only. The output level is adjusted by RV8.

8.2.5.3 Crosspatch Recorder The Crosspatch recorder records all crosspatch audio including the console operator if the operator speaks on a crosspatch. The output level is adjusted by RV9.

8.2.6 Auxiliary Speaker Outputs

Three auxiliary speaker outputs are available to the rear of the UIM. Each speaker output is 600 ohms unbalanced and can be driven to 0.77V. All speaker outputs are brought to the six position plug-in terminal strip TB6. Counting from left to right the pin-out is as follows:

Pin Description Adjustment pot 1 Auxiliary Select high RV11 2 Auxiliary Select low 3 Auxiliary Unselect high RV12 4 Auxiliary Unselect low 5 Auxiliary Crosspatch high RV13 6 Auxiliary Crosspatch low

8.2.7 Handset/Headset connector J5 on the UIM Analog board is the interface for both the handset and headset (though only one may be plugged in at a time). J5 is identified on the rear panel as HANDSET/HEADSET. The handset is plugged directly into the modular jack. The headset must use the Vega HB-2 headset interface box. If a handset or headset is being used JP3 on the UIM analog board must be in the A position. The following chart gives level adjust information: Potentiometer Parameter RV1 Transmit level out. Factory set so nominal voice level drives TP7 to about 600mVrms. RV2 Side tone level to earpiece. This level will be affected by any adjustment of RV1. Adjust for comfort. RV3 Phone audio level to earpiece. This pot is for phone call audio only. Adjust for comfort. RV5 Select audio level to earpiece. This pot is for Select audio only. Adjust for comfort.

8.2.8 Desk microphone/Gooseneck connector J9 on the UIM Analog board is the interface for both the desk microphone and gooseneck microphone (though only one may be plugged in at a time). J9 is identified on the rear panel of the UIM as DESK MICROPHONE/ GOOSENECK MICROPHONE. The transmit level of this microphone input is controlled by RV6. Place the microphone at the distance it would normally be from the operators’ mouth and adjust RV6 for the desired output level at TP21. This level is factory set for about 600mVrms at nominal voice level.

65 Vega’s C6124

This audio level will be inserted to an Automatic Level Control that will not allow audi o to rise above 770mVrms. Setting TP21 for 600mVrms allows a good amount of audio deviation before the voice is compressed (subjectively determined).

8.3 Other Adjustments

8.3.1 VU meter

RV10 on the UIM Analog board allows the setting of the sensitivity for the VU meter.

8.3.2 LCD Contrast

R38 on the UIM Digital board allows adjustment of the contrast on the LCD touchscreen.

8.3.3 Unselect Mute Level

The level that the Unselect audio will be at the time when it is muted is set by RV16.

9. Sample Setup Procedure

The following example sets up the audio levels on both the transmit and receive sides.

9.1 UIM Transmit Path: The transmit path begins at the microphone of your choice and ends with the transmit card of your choice.

9.1.1 Microphone ad justments

There are two microphone inputs to the C-6124. Both inputs are accessible from the back panel of the User

Interface Module. One is a four -wire plug and the other is a six-wire plug. The four-wire plug will accept either a handset or headset. The six -wire plug will accept either a desk microphone or a gooseneck microphone. Both plugs may be used at the same time. Keep in mind, though that the six -wire plug has priority. Transmit audio from the sixwire plug is blocked only when the PTT of the 4 wire plug is active or when a phone conversation is active. Both the handset/headset and the desk/gooseneck microphone inputs go through dedicated preamplifier stages and are then summed together before being processed through an Automatic Level Contr ol (ALC) circuit (commonly known as “compressors”). In tuning the microphone levels the goal is to adjust the preamps so that nominal voice levels through both microphone (if two are being used simultaneously) are of equal level at the output of the summing amp. The following cookbook will guide you through the tuning process:

9.1.2 Determining the knee of compression

The system is designed for a .77V maximum on the internal busses. The ALC will limit the output signal to .77V. This will happen automatically, though. Your task is to tune the microphones so they go into compression when you want them to. Your desired knee of compression may be nominal voice level. This setup may be performed simply by making a tone (by human vocal cords) into the microphone at about the level you expect the operator to be talking at the distance from the microphone that the operator is likely to be. Adjust the microphone preamp for a predetermined level at the summing amp. The level at the summing amp is not very important. What is important is that the level be the same at the output of the summing amp for both microphones. At the factory we choose .08V. The respective preamps will bring nominal voice from the microphones up to .08V and the ALC will convert the .08V to .77V. In the following examples .08V will be used to give an absolute example.

9.1.3 Adjusting handset/headset microphone levels Make a vocal tone into the handset while adjusting RV1 on the UIM analog PCB for .08V at TP7. You should see .08V at TP9, the output of the summing amp. While you are here adjust the sidetone level by adjusting RV2 until you can comfortably hear yourself in the earpiece. If a handset/headset is part of the system JP3 on the UIM Analog must be in the A position. Speak into the handset and listen to the earpiece. You should hear a portion of your voice being routed back to the earpiece. This is known as sidetone. The sidetone level is adjusted by RV2.

9.1.4 Adjusting desk microphone/gooseneck microphone levels

Make a vocal tone into the desk microphone/gooseneck microphone at the distance you expect the operator

to be at. Adjust RV6 on the UIM Analog PCB for .08V at TP18. You should see .08V at TP9, the output of the summing amp. If there is not a handset/headset in the system be sure that JP3 is in the B position.

9.1.5 Setting the knee of compression

With the nominal voice level coming in through either of the microphone inputs adjust RV15 until you see a

level of .59V at TP10, the ALC output. The ALC will compr ess signals to .77V (+3db/-1db) over an increase of input of up to 30db. What this means is that yelling into the microphone will not produce more than 3db above nominal voice level. It is up to the technician to determine where the “knee” of compression is. Generally, the knee of compression for the C-6124 ALC starts at .59V and ends at around .77V. The consoles are shipped from the factory with the assumption that the “knee” is at .59V.

9.2 Alert tone adjustments

The Alert tone button on the touchscreen front panel produces a 1000Hz tone on the transmit audio. If no cards are in the transmit condition the console will key up the Selected cards and transmit the Alert tone. If the Selected cards are already in the transmit mode when the Alert button is pressed then the C-6124 will just add 1khz to the transmit audio path. Note that to produce an Alert tone the ALERT button on the touchscreen must be pressed to enable the oscillator. There is a way to lock the Alert tone in the enable position. That is to remove the jumper plug for JP7 on the UIM Analog PCB. This will place a 1000Hz signal on the transmit path until the jumper is restored to the A position (the B position disables the oscillator).

9.2.1 Alert tone frequency

69 Vega’s C6124

An onboard analog oscillator produces the Alert tone. The frequency is fine-tuned by adjusting RV17 while measuring the frequency at TP5 on the UIM Analog PCB. The consoles are shipped out with the frequency at 1000Hz (+/-10Hz).

9.2.2 Alert tone level The Alert tone level is set by adjusting RV14 while measuring at TP6 on the UIM Analog PCB. This level is set relative to the voice audio level. TP6 is the output of the summing amp which drives the transmit bus. All audio signals, which come from the UIM Analog, are at TP6 at the levels relative to voice that they will be transmitted. At this point the voice audio has been limited to .77V. The consoles are shipped with the Alert tone 6db below voice. Since voice is at about .77V, RV14 can be adjusted for an Alert tone level of .39V TP6.

9.3 SWITCH BUS MODULE (SBM)

TX audio across the Switch Bus Module (SBM) is somewhat uneventful. There are no settings on this module.

9.4 Tone Line Module (TLM) Transmit Path Adjustment

Once microphone audio gets to the TLM it will be routed through a 2175Hz notch filter to remove 2175Hz components from the voice. This is done to make sure that no component of the microphone audio will interfere with the 2175Hz hold tone. Out of the notch filter microphone audio is summed together with the last of the signaling components. TP7 on the TLM is the output of the summing amp that combines microphone audio, DTMF tones, crosspatch audio, and tone signaling. From this point the total transmit audio mix is sent to the output drivers. There are two sets of adjustments on the TLM. The internal set is the notch and bus interface settings. These settings, once set by the factory should not need to be changed. They are placed in an area that requires an extender card to adjust. The external set of adjustments is the input/output controls that are accessible by only removing the back panel of the SBM. These controls include, among others, TX output level and RX input level.

9.4.1 External Settings The C-6124 has been factory set so that voice audio in full compression will be at the same level as the function tone. This is generally .77V. Press and hold the Release button and then press the Select button without letting go of the Release button. Let go of both buttons when the red LED in the Instant PTT button lights. This will produce a function tone. Fully load the card with the load it will see in the system and adjust the RV4 so the output is at .77V.

9.4.2 Internal Settings

To set every level on the TLM you need an extender card (avai lable from Vega) to remote the TLM. Carefully consider whether changing these settings necessary. All routine level changes are done from the back of the console.

9.4.2.1 Tone generator output

The tone generator may be commanded to give a continuous tone out at the function tone frequency by pressing and holding the Release button and then pressing the Select button. Release both buttons when the Instant PTT light starts flashing. Adjust RV6 for .77V at TP7. This sets the reference level at TP7 that all other output levels will be set to. Disengage the tone by pressing the Select button. Jumper JP7 can be used to disable the tones. To get tones out verify that JP7 is in the A position.

9.4.2.2 Microphone relative output level

Hook up a signal generator to the TB3 terminal block on the back of the UIM analog. Hook audio to pin 3 and the common lead to pin 2. Send in a 2175Hz tone at .77V. Verify that all is well by measuring a .77V, 2175Hz signal at TP6 of the UIM Analog. Once this is established adjust RV7 on the TLM for .77V at TP3. Verify .77V at TP7.

9.4.2.3 Crosspatch output level

This level is set just like microphone audio is set. In this case you need to place the card in a crosspatch. Do this by pressing and holding the Crosspatch Select button and pressing the card Select button. The LED in the Select button will turn green. Make sure a tone is being inserted to the Aux. Audio terminals (TB3) of the UIM Analog as described in item 2. Press and hold the XPATCH PTT button on the front of the UIM. You will monitor the inputted signal at TP12. Adjust RV8 for .77V at TP12.

9.4.2.4 Notch filter adjustment

Remote Control Console 70

The notch filter on the TLM is a very steep notch designed to remove the 2175Hz component out of the transmit voice. This prevents the voice audio from affecting the hold tone through superposition of 2175Hz frequencies. While in-phase signals will add together and give more than .08V, out-of-phase signals will cancel each other and there is danger of the remote adapter dropping the transmission due to loss of hold tone. Each potentiometer is “potted” with an orange substance to keep the pots from drifting during transportation of the console. To retune the notch filter the now hard orange substance must be chipped off. The notch filter works by employing a hi-Q state variable bandpass filter at 2175Hz, shifting the bandpass output by 180 degrees, and then summing it back with the original signal. RV11 adjusts the bandpass frequency and RV10 adjusts the phase that the bandpass output is summed in at. To adjust the filter insert the tone which is to be notched out (insert as described in step 1 above). Turn RV11 to the smallest level at TP6. Once this is done, adjust RV10 to take the level at TP6 down a little more. The filter is finished off by performing a balancing act between adjusting RV10 and RV11 as you go back and forth to try to get the smallest signal level at TP6.

9.4.2.5 Output driver

RV4 controls the output level of the TLM. Set this by loading the card output with the equivalent of the load the system will apply to the card. Activate the card test tone by pressing both the Release and Select buttons then adjust RV4 for .77V output. The transmit side may be jumper set to show 600, 1200, 1800, or 2400 ohm impedance. The output may also be set up for either two or four wire interface. See the signal flow chart for jumper assignments.

9.4.2.6 Transmit Monitor A transmit monitor is jumper selectable to allow the receive side to monitor the transmit pair in four wire

mode. When JP1 is in the B position the TX Monitor is engaged. To set the TX Monitor insert the nominal audio level on the transmit pair. If your system is set around .77V on the transmit side apply .77V to the transmit pair. Then adjust RV2 for .25V at TP8.

9.4.2.7 DTMF Output To set the DTMF output level, it is easiest to have peak amplitude in mind and monitor TP7 on the TLM

with an oscilloscope. Program in a 16 digit code on the UIM dial screen and transmit it out the line that is being programmed. Adjust RV15 for the output level desired. At TP7, the output should be measured relative to the hold tone.

9.5 TLM Receive Path

The Receive path begins at the input to the line card and ends with a speaker or earpiece. As with the TX path, there are internal and external adjustments. The external adjustments are, usually, the only adjustments that need to be set. The internal adjustments should not need to be modified.

9.5.1 4-Wire or 2-Wire?

If the circuit is a four-wire circuit then JP10 and JP11 are in the B position. The RX impedance for the fourwire mode is generally 600 ohms. If this card is the only card on the line or if it is a terminating card for a group of cards hooked in parallel then the impedance of the RX side should be 600 ohms. This is accomplished by changing JP12 to the A position. If a high impedance (10k) is required then place JP12 in the B position. If the circuit is a 2 wire circuit then JP10 and JP11 are in the A position. The 600 ohm line impedance is provided by the TX side so RX impedance should be high. Move JP12 to the B position for a 10k ohm RX impedance.

9.5.2 External Adjustments

9.5.2.1 Input Amplifier adjustment

Apply a normal input level to the receive pair of the TLM. The cards are shipped with the assumption that the input level will be about .25V. Adjust RV1 for .25V at TP9.

9.5.2.2 Line Activity Monitor (LAM) / Squelch Control The green LED in the Unselect button is the LAM. It will blink when activity is on the line. The TLM’s are shipped from the factory to trigger at –25 V. To move the trigger point turn RV9 fully counterclockwise (RV9 is available from the back). Insert a tone to the receive pair at the level that you would like the LAM to trip at. Verify that the LAM has stopped blinking. Slowly turn RV9 clockwise until the LAM triggers. Note that the LAM can be used as a squelch circuit. The Select and Unselect audio paths may be independently controlled by the LAM. If you

71 Vega’s C6124

would like Select audio to be muted until the LAM triggers move JP4 to the A position (B position disables). If you would like Unselect audio to be muted until the LAM triggers move JP3 to the A position (B position disables).

9.5.2.3 Recorder Output A 600 ohm balanced output provides a summing of the transmit and receive audios for the use of an external recorder. Jumper options allow the TX path to be summed in with tones (JP14 = B) or without tones (JP14 = A). The option for including the tones is intended for test purposes. If a system problem is being detected, recording the tone output may help debug the problem. A jumper also allows crosspatch audio to be included (JP15 = A) or not included (JP15 = B). To set the recorder insert a .77V signal to the receive pair and adjust RV14 (accessed from the back) for .77V at the recorder output which is fully loaded.

9.5.2.4 RX Automatic Level Control With the nominal voice level coming in through the receive pair adjust RV5 until you see a level of .59V at TP4, the ALC output. It is up to the technician to determine where the “knee” of compression is. Generally, the knee of compression for the C-6124 ALC starts at .59V and ends at around .77V. The consoles are shipped from the factory with the assumption that the “knee” is at .59V.

9.5.3 Internal adjustments

To set every level on the TLM you need an extender card (available from Vega) to remote the TLM.

Carefully consider whether changing these settings necessary. All routine level changes are done from the back of the console.

9.5.3.1 RX Automatic Level Control With the nominal voice level coming in through the receive pair adjust RV5 until you see a level of .59V at TP4, the ALC output. It is up to the technician to determine where the “knee” of compression is. Generally, the knee of compression for the C-6124 ALC starts at .59V and ends at around .77V. The consoles are shipped from the factory with the assumption that the “knee” is at .59V. The factory sets the ALC by inserting –10V, adjusting RV1 for .25V at TP9, and then adjusting RV 5 (knee of compression) for .59V at TP4.

9.5.3.2 2175Hz notch filter

The notch filter on the TLM is a very steep notch designed to remove the 2175Hz component out of the receive audio. This prevents the any transmit 2175Hz getting to the speakers when the console is in four wire TX monitor mode. Each potentiometer is “potted” with an orange substance to keep the pots from drifting during transportation of the console. To retune the notch filter the now hard orange substance must be chipped off. The notch filter works by employing a hi-Q state variable bandpass filter at 2175Hz, shifting the bandpass output by 180 degrees, and then summing it back with the original signal. RV13 adjusts the bandpass frequency and RV12 adjusts the phase that the bandpass output is summed in at. To adjust the filter insert the tone which is to be notched out to the receive pair. The tone should be 10 db into compression to give the maximum signal the circuitry will encounter. For example, if the input levels have all been set to a .25V reference insert a .77V signal to set the notch filter. Turn RV13 to the smallest level at TP2. Once this is done, adjust RV12 to take the level at TP2 down a little more. The filter is finished off by performing a balancing act between adjusting RV12 and RV13 as you go back and forth to try to get the smallest signal level at TP2.

9.5.3.3 Bus Driver

The internal bus structure is set up for .77V, fully compressed audio. To set up the RX bus driver insert a tone to the receive pair that will put the TLM receive path into compression (at the factory we use .77V input). Adjust RV3 for .77V at TP11.

9.6 Switch Bus Module (SBM)

The only receive adjustment on the switch bus module is the individual Unselect volume controls. These volume knobs are the ones mounted to the front panel of the Switch Bus Module. They can attenuate the line’s Unselect audio all the way off.

9.7 UIM Analog

Remote Control Console 72

When the receive audio gets to the UIM Analog it has been segregated into an Unselect path or a Select path. The only adjustments on the UIM Analog for receive audio is for the handset/headset earpiece. Two paths drive the earpiece. The first is the receive path from a TLM. The second is the receive path from a phone line. To set the TLM path insert a signal to the receive pair that is in full compression (factory test is .77V). Adjust RV5 for the upper range of the comfortable listening level in the earpiece. This represents the loudest it would get. Normal conversation will be lower. To set the phone path, establish a phone conversation and adjust RV3 for comfortable listening level in the earpiece.

9.8 Phone Line Module (PLM) The PLM has two modes of operation. It may be configured as a normal phone line (PLM mode) or as a dedicated dialup line (DLM mode). A simple adjustment scheme for the PLM mode is to establish a phone call and adjust levels using the person at the other end as a test unit. Talk and ask how your voice level is. Adjust RV4 for voice audio level out. Ask the other person to talk and adjust the receive volume using RV1. If the card is to be used as a Dial -up line (DLM) then a more objective test may be performed. To put the card in DLM mode turn off power to the console and place JP1 of the PLM in the A position. Place JP7 in the A position to enable the tone generation. Turn on the console again for testing.

9.8.1 DLM Transmit path The first item to do in the transmit path is to set the output level. Verify that JP7 is in the A position (enable tones) and that JP1 is in the A position (DLM mode). If you had to change JP1 to the A position you must cycle power on the console as the mode of the card is set upon power up. Once this is done monitor the phone line and press the Instant PTT button. While this button is pressed a low level tone will be transmitted. Adjust RV4 for .05V across the phone line. To set up the microphone input, insert .77V to pin3 of TB3 on the UIM Analog PCB (AUX AUDIO Input) and ground the signal generator on pin 2. In the following tests and adjustments you can get this signal to the card by pressing the Instant PTT button on the DLM card. Adjust RV2 for .77V at TP7. To set up the Crosspatch path place the DLM in a crosspatch. Keep the test signal for the microphone circuit. Press the Crosspatch PTT button on the UIM front panel and adjust RV8 for .77V at TP7.

9.8.2 DLM Receive path Insert .77V into the DLM through the modular connector. Adjust RV1 for .77V at TP9. Adjust RV3 for .77V at TP11. This sets up the receive path to drive the internal bus. RV1 controls the input level which will be limited to .77V. RV3 controls the bus driver. It is important the maximum input level drives the bus at .77V. Therefore, if changes are made to RV1 to raise or lower the input level verify that RV3 is adjusted to maintain .77V on the bus. The Line Activity Monitor (LAM) is an LED that will light when a certain minimum audio level is detected. To set the LAM circuit, insert the audio level that you wish the LAM to trigger at and adjust RV9 so that the LAM LED is lit. The easiest way to do this is to adjust RV9 all the way counter clockwise and slowly turn it clockwise until the LAM comes on.
