iv Vega’s C1610

Remote Control Console 1

1 Introduction

The model C-1610 is a unique multi-channel, multi-format, and self-contained desktop radio control console. The C-1610 sports a Vacuum Florescent LCD display, which provides channel alpha/numeric indication, clock and

audio-level meter with a modern membrane keypad. These features allows for a more flexible dispatch environment in which the console may be installed. The dispatcher can easily operate the console while sitting or standing.

The C-1610 is a Digital Signal Processor (DSP) based design, allowing easy field programmability using the DTMF key pad on the front of the console. Unlike other manufacturers’ equipment, no additional software is required to program the C-1610 console. Modifications and enhancements can generally be made via a software change only. If the user determines they require a special feature enhancement, please contact the Vega Sales Department for cost and feasibility.

The C-1610’s modular design offers selection and control of up to six base stations, along with selection of ten frequencies. The base configuration includes one line card, allowing 2 lines of control. Each line card consists of two independent channels that offer crossmute capability and squelch control feature eliminating the unwanted noise that is generally associated when monitoring a selected or unselected line.

The C-1610 will accommodate a desk microphone (or gooseneck microphone) along with a handset (or headset) as indicated on the side of the C-1610 console. 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.

The console is normally used in conjunction with up to six functionally matching Vega 223C Series (or equivalent) tone-remote panels located at each base station. The console is compatible with Motorola, ComNet Ericsson/GE, and other tone-remote control systems employing the industry-standard sequential tone-control format.

The console is connected to the mating panels by means of voice-grade or better leased or private lines (including microwave circuits). Metallic or DC continuity is not required.

Version 4.5 of the software introduced several new features to the console, including: incoming select call, per line TX disable, per line Unselect audio lock, and the ability to mute unselect audio during PTT. A number of minor issues were fixed as well.

2 Hardware Overview

The C-1610 is a multi-line, multi-mode console designed specifically for medium level system requirements. All functions are house d in a single small modern loo ki ng console.

2.1 C-1610 Console

The C-1610 consists of the following sub-assemblies enclosed in the single case: Main Processing Board, Line Interface Cards, Keypad/Display Board, and speaker amplifier.

2.1.1 Main PCB

The Main PCB is mounted to the bottom of the enclosure using 5 #6 screws. It contains the DSP which handles all audio processing and user interface features. Three two channel Digital to Analog Converters (DACs) are utilized to generate audio for transmission, recordings, auxiliary speaker, main speaker, earpiece, and keyboard feedback. One two channel Analog to Digital Converter (ADC) is resident on the main board which digitizes both the microphone inputs and the auxiliary audio inputs. Each line card contains an ADC as well for the two lines of audio supported on the card. Three 30 pin card slots reside on the main board for each optional line card. A 20 pin header is used to interface the keypad to the Main Board. All audio detection, generation, and filtering is performed within the DSP. Two potentiometers are available for adjusting the handset and desk microphone input levels. A three pin header is supplied on the main board which connects to the unselect audio control potentiometer.

2.1.2 Keypad PCB

The Keypad board is interfaced to the main board via a 20 pin ribbon cable. The board contains the circuitry to drive the 39 LEDs, decode the keypad matrix, and interface the DSP to the display. The display itself is mounted to the Keypad PCB by a 14 pin header and three screws with spacers.

2.1.3 Line Card

The Line Card is a radio control card using either the standard tone control format compatible with Motorola and ComNet Ericsson/GE or Local Control 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. This is usually a software only change. Each card supports two lines. Four potentiometers are mounted on the card supporting tuning of the transmit and transmit monitor levels.

2.1.4 Internal Speaker Amplifier

The internal speaker has a 5 watt amplifier mounted on the backside of the front cover. Which has one volume control input to which the “Select” volume control is connected. A jumper is used for setting a minimum output level, allowing for audio at some level always being present in the internal speaker.

A desk microphone (or gooseneck microphone) may be installed for operation along with a handset (or headset) as indicated on the side of the C-1610. 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.

3.1.1 Common Controls and Indicators

Select Volume Control: Adjusts the summed speaker level of the Selected and Unselect audio’s. A minimum volume level can be set on the speaker card so that the console operator can not turn the volume to zero.

6 Vega’s C1610

Unselect Volume Control: Adjusts the speaker level of the Unselected audio. A minimum volume level is preset on the main PCB so that the console operator can not turn the volume off as long as the master minimum volume is active on the speaker amplifier (JP1). Refer to page 11 for more detailed information.

Optional Handset: When you come off hook the handset receive audio is transferred to the earpiece and the microphone mouthpiece becomes active. Unselect audio that is being routed to the external speaker will not be affected.

VU Meter: Displays Selected receive and Microphone audio bus levels. This meter is shown on the top line of the display and utilizes the first 12 display elements from the upper left.

4 Functional Description

4.1 Grouping Options

4.1.1 Basic Line/Function Tone Operation

The basic operating scenario would be a single line and function tone selected. Lines can be selected individually by pressing any LN1-LN6 and function tone butt on F1-F10. Upon keying the microphone, a high level guard tone followed the selected function tone is sent out, the low level guard tone is then transmitted along with the microphone audio. Each Line/Function pair is unique and can have its’ own alphanumeric characters assigned to it in the programming mode. The default characters have the LnX FY label in the display with X the line number and Y the function number. Function Buttons can have either single or dual functions and is setup in the t ech mode.

4.1.2 GRP and TX ALL Buttons

The GRP button is a press ON/OFF button which disables the 1of N functionality of the console. When the GRPSEL button is selected it will illuminated and the operator can set up a Simul-group with as many tone lines desired. As long as the button is illuminated the operator may add or delete lines in the group. The Green LED above each line selection button denotes that the line is selected for transmission and reception. When the operator is finished setting up the Simul-group the operator presses the GRP button again to revert back to the 1of N mode.

The group button is also used to select up to four preprogrammed groups. Within the tech mode, it is possible to set up preprogrammed groups. By assigning certain groupings of lines to the Groups ‘A’-‘D’ a simple two button sequence can be setup to select multiple lines.

Lines that are setup as Local Control cannot be mixed with tone control lines in the same group select mode.

Note:

Likewise you cannot TX ALL if you have Local control and tone control lines mixed. You will receive an ERROR MESSAGE. They must all be of the same type of control lines tone or local control.

TX ALL (Transmit All)

transmissions without having to group select one at a time. To initiate Simulcast, momentarily touch the "TX ALL" on the keyboard. The line description will change to

"Group", and all available lines will automatically be Selected. To disengage Simulcast, simply Select a single line in the usual manner, or press TX again to revert to the previous

setup.

You cannot TX ALL if you have Local control and tone control lines mixed. You will receive an ERROR

Note:

MESSAGE. They must all be of the same type of control lines tone or local control.

4.1.3 UNSEL and RX ALL Buttons

The UNSEL Button functions the same way as the GRP button. The UNSEL button is a press ON/OFF button. When the GRPSEL button is illuminated the operator is able to set up any combination of lines as desired for monitoring only. As long as the button is illuminated the operator may add or delete lines to the group. The red LED above each line selection button denotes that the line is Unselected for reception. When the operator is finished setting up the group the operator presses the UNSEL button again to turn off the mode.

RX ALL (Receive All):

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

4.2 Other Control Buttons

4.2.1 Supervisor Button

The SUP Button is used to disable all units on a particular line. Its connection is similar to that of the crossmute function. Tech mode is utilized to determine which consoles will have supervisory capability. It is possible to setup only specific consoles with this feature. If a console has the feature enabled, by pressing the SUP Button, the Button will light and disable all connected paralleled consoles. On the consoles that are being supervised, the SUP Button will blink, if they have selected a line that the supervisor has selected. Figure 4 shows the connection scheme required to utilize this function. Pin 2 of all consoles are connected together. In addition, Pin 8 is also connected together on all consoles, serving as a common ground for all consoles. Assuming that console 1 has supervisory capability, when activated, Line 1 on parallel consoles 2 and 3 would then be inhibited.

4.2.2 MUTE Button

The MUTE Button is used to mute unselect audio. It is programmable in tech mode to be a mute when pressed, or mute for a programmable period of time. As long as MUTE is active, the Button will be lit up.

4.2.3 AUX Button

The AUX Button has up to four functions, selectable in tech mode:

1) DTMF store and transmit DTMF

2) Second Alert tone ALERT

3) Toggle relay control TOGGLE RELAY

4) Momentary relay control MOM RELAY

Option 1, DTMF store and transmit, allows a programmed string of DTMF characters to be entered and transmitted. In addition, the function will remember the last string sent and can be recalled by pressing a Program Button.

Option 2, ALERT, allows the AUX Button to serve as the Alert 2 Button. In this mode it sends out the programmed Alert 2 tone.

Option 3, Toggle Relay, give the AUX button the ability to control the AUX RELAY output on the back panel. When pressed, the Button will light and the relay will close. The next time the AUX button is pressed, the Button’s light will turn off and the relay will open. The relay is rated to handle 500mA at 12VDC or 250mA at 115VAC.

Option 4, Momentary Relay, closes the relay for as long as the AUX button is pressed. The relay is rated to handle 500mA at 12VDC or 250mA at 115VAC.

4.2.4 Alert Button

The Alert Button is used to send the programmed Alert sequence. Tech mode is used to set up the cadence assigned to this Button.

4.2.5 Intercom (IC) Button

When the IC button is pressed and held down the C-1610 transmits audio without activating the tone generator. Intercom is a PTT operation with the tone generator disabled. This is useful for communications between paralleled consoles.

5.1 INTRODUCTION/DEFAULTS

The Line Card for the C-1610 system provides communication with any standard tone remote system. It is shipped from the factory in the following state: 4 Wire mode 600 ohm output impedance Note that there are now two versions of this card. The jumper numbers have remained the same as well as their functions. The level setting POTs have changed. They are labeled on the board and noted within this chapter. Figure 5 shows the older Rev A board, and Figure 7 shows the Rev B board.

5.2 INPUT/OUTPUT

Two Line connectors are available for external access. The connectors are standard eight pin RJ-45 connectors. The upper connector on each card is designated as 1 and the lower as 2. The slot that the card is placed in designates line 1&2 or 3&4 or 5&6.

5.3 FEATURE DESCRIPTION

5.3.1 Crossmute

When a parallel console operator keys a microphone in the same room, the crossmute function mutes the receive audio path of the other parallel consoles. This prevents any unwanted audio loops which would occur causing a loud squeal on the paralleled speakers.

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 in Figure 7. Pin 8 must be connected to provide a common ground. Figure 7 illustrates the connections between consoles 1 through 3 that are in the same room and when one transmits, the receive audio on line 1 will be muted. Console 4 is off-site with no possibility of feedback, therefore, it is not being muted. function will not work between crossmuted consoles.

5.3.2 Relay Contact Closure For Local Control

The relay is normally open and provides a dry contact closure during PTT functions between pins 7 and 8 of the line jack. The relay closure can carry 500mA at 12VDC or 250mA at 115VAC. When using the intercom function the

Remote Control Console 13

relay is not activated.. If this relay closure is used for local control (or any other case where tone bursts are not used for signaling) disabling the tone generation is recommended by entering the tech mode.

5.3.3 Two-Wire/Four-Wire Mode

Each Line Card comes standard with a jumper selectable two or four-wire option. Note: The Line Cards are shipped in the four-wire mode. Two-wire mode is accomplished by the following jumper positions:

Line 1, 3, 5: Line 2, 4, 6:

Two-Wire:

JP13 A JP11 A

Four-Wire:

JP12 B JP10 B JP13 B JP11 B

The RX pair is now on pins 3 and 6 on the connector 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.

5.3.3.1 RX Side Settings

The RX side is jumper selectable for a 600 ohm impedance or 10k ohm impedance. If only one Line Card is on the line (no parallel consoles) then place J9 (Line 1,3,5) or J8 (Line 2,4,6) in the A position for a 600 ohm line impedance. If more than one Line Card is on one line then place J9 (Line 1,3,5) or J8 (Line 2,4,6) on 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 thereafter is set for an impedance of 10k ohms. As the chart indicates on the following page , the more consoles bridged on the line, the lower the line impedance and the greater the loss in audio level.

Console added 1 A 604 604 0.0 2 B 10k 569 -0.5 3 B 10k 539 -1.0 4 B 10k 511 -1.5 5 B 10k 486 -1.9 6 B 10k 464 -2.3

Level adjustment can be made to the receive audio by entering the tech mode on a per line basis.

5.3.3.3 Transmit Monitor

In a four-wire system the transmit line may be monitored by the receive circuits by changing a setting in tech mode. Refer to section 5.4.1.2. for the monitor level setup adjustment. The transmit monitor is not needed in two-wire mode as the transmit audio is already on the receive circuit.

5.4 Level Adjustments

Figure 5 and Figure 7, in this secion, shows a top view of the Line Card with the adjustment points labeled. The potentiometers are available without taking the card out of the chassis.

5.4.1 Transmit Side Adjustments

The transmit audio consists of multiple audio sources – microphone audio, AUX input, function tones, and DTMF tones. Each audio sources is summed or generated in the DSP with the analog signal being generated on a single DAC. The following is a list of the potentiometers that affect the transmit path.

Description

5.4.1.1 Transmit Level Setup

The transmit level potentiometers are used to adjust the output levels of the transmit audio so that it is calibrated with the onscreen level sets found in the tech mode. Calibration of the Transmit lines will vary depending on system variables as well as the number of consoles found in parallel on the line. The tech mode should be used to generate a test tone at a given amplitude. R55 (R41-Rev B) and /or R56 (R42-Rev B) should then be adjusted with a level meter used to set the actual output level to match the generated value.

5.4.1.2 Transmit Monitor Setup

The transmit monitor provides a portion of the transmit audio of a four-wire circuit 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 select a line and press the intercom button. Adjust R57 (R40-Rev B) and/or R58 (R39-Rev B) on each four-wire circuit until the level is comfortable in the handset/headset earpiece or the speaker.

5.4.1.3 Receive Level Setup (Rev B Line Card only)

The receive side level potentiometers are used to adjust the input levels into a range that is acceptable to the C-1610. Typically, a +10dBm test tone is injected in to the C-1610 as receive audio. The audio level is then measured at TP2 for Line 1 and TP1 for Line 2 with respect to ground. The measurement should be about 3.4 Vpp or 1.2Vrms. However, if receive audio levels are not in the +10dBm range, these pots can be used to bring the audio level up to

Remote Control Console 15

the desired receive levels. 3.4Vpp is about the maximum value for the loudest receive audio. Above 3.4Vpp will saturate the ADC input stage and distortion will occur.

5.5. Microphone Level Adjustment

Adjusting handset/headset microphone levels. Make a vocal tone into the handset while adjusting R72 on the Main PCB for 3.5Vp-p at TP2. The sidetone can be adjusted from within the tech mode. Speak into the handset and listen to the earpiece. You should hear a portion of your voice being routed back to the earpiece.

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 positioned and adjust R71 on the Main PCB for 3.5Vp-p at TP7.

5.6. Minimum Speaker Level Adjustment

A minimum volume level can be set by moving JP1 to “B” position on the speaker Amplifier PCB, preventing the operator completely turning off the volume of the speaker.
