Remote Control Console 1

1 Introduction

The model C-2000 is a full featured single -channel, multi-format, and self-contained desktop radio control console. Its sleek and modern look will compliment any surroundings.

The C-2000 is a Digital Signal Processor (DSP) based design, allowing easy field programmability using the DTMF keypad on the front of the console. Unlike other manufacturers’ equipment, no additional software is required to program the C-2000 console. Modifications and enhancements can generally be made via a software change only. If the user determi nes they require a special feature enhancement, please contact the Vega Sales Department for cost and feasibility.

Initial Line level adjustments are made via potentiometers allowing for ease of installation. Should additional adjustments be required, they can be made in the programming mode. AGC on the receive and microphone audio paths help stabilize line level adjustments.

The C-2000’s modular design offers control of one base station, along with selection of 99 frequencies. The line interface offers crossmute capability and squelch control feature eliminating the unwanted noise that is generally associated when monitoring a line.

The C-2000 will accommodate a desk microphone along with a handset (or headset) as indicated on the side of the C2000 console. In addition to the external microphone options, a built in panel microphone is available by pressing the PTT on the front of the panel. When a PTT occurs from any of the three microphones, the others will mute so as not to pick-up unnecessary ambient noise during transmission. When the handset is enabled and taken off hook the receive audio is transferred to the earpiece.

The console is normally used in conjunction with a matching Vega 223 Series (or equivalent) tone-remote panel located at the base station. The console is compatible with Motorola, MA/ComNet Ericsson/GE, and other toneremote control systems employing the industry-standard sequential tone-control format.

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

2 Hardware Overview

The C-2000 is a single -line, multi-mode console designed specifically for small to medium level system requirements. All functions are housed in a single small modern looking console.

2.1 C-2000 Console

The C-2000 consists of the following two sub-assemblies enclosed in the single case: Main Processing Board and Keypad/Display Board.

2.1.1 Main PCB

The Main PCB is mounted to the bottom of the enclosure using 4 #6 screws. It contains the DSP that handles all audio processing and user interface features. One stereo Digital to Analog Converter (DAC) is utilized to generate audio for transmission, handset sidetone, and receive audio. One stereo Analog to Digital Converter (ADC) on the main board digitizes audio from the line, microphone and the auxiliary interface. All audio detection, generation, and filtering are performed within the DSP. Five potentiometers are available for I/O signal level adjustment, in addition to the software level control.

2.1.2 Keypad PCB

The Keypad board is interfaced to the main board via a 34-pin ribbon cable. The Keypad board contains the LED’s, the entire key map matrix, the dual seven-segment display and the panel mi crophone. The driver circuitry for each component is located on the Main PCB.

2.1.3 Line Interface

The Line Interface is an 8 pin RJ-45 connector, using either the standard tone control format compatible with Motorola and M/A ComNet Ericsson/GE or Local Control relay closure. The line interface may be hardware

Figure 1 Front Panel Diagram

3.1 Front Panel

Figure 1 shows a view of the Front panel. The Front panel contains the user I/O. It features volume and Function Tone selection, intercom and monitor functions, DTMF keypad, panel PTT and microphone, as well as the dual seven-segment display.

3.1.1 Common Controls and Indicators

Volume Control: Adjusts the receive audio speaker and handset level of the audio present on the receive inputs of

the line interface. A minimum volume level can be set in the setup mode so that the console operator can not turn the volume to zero. When adjusting the level up or down, the display shows the selected level on a relative scale with 0 being off and 25 being full volume.

Panel PTT Pushbutton: When pressed, audio from the panel microphone, or desk microphone if enabled, will be sent on the TX line interface.

DTMF Keypad: The DTMF keypad is used for transmitting DTMF. The DTMF keypad is also used in the setup mode. It can also be disabled in user mode.

Dual Seven-Segment Display: Displays selected frequency and will update with parallel frequency selection if active. Function Buttons Up-Down: The Up and Down arrows, just below the display, are used to select the desired function

tone. Pressing the arrows changes the value in the desired direction. Once the desire function tone is selected, the unit will pause, blink and then send the function tone shown on the display. The pause and blink rate are programmable in setup mode. Only enabled function tones are displayed and transmitted. No hold tone is associated with the changing of the function tone. A function tone shall remain selected until the operator changes the setting.

Transmit LED: This LED lights when any PTT source is depressed keying up the console. It will also blink if a Hold tone is detected on the TX audio line. This would indicate to the operator that another console is currently transmitting on the channel.

Monitor: When the Monitor button is pressed a Monitor tone burst is sent out. The Monitor tone burst consists of a guard tone and function tone of 2050Hz(default value). The MON LED lights for the duration of the tone burst.

Intercom (IC): When the Intercom button is pressed and held down the C-2000 shall transmit audio without activating the tone generator or local relay. Intercom is considered a PTT operation with the tone generator and local control relay disabled. The selected microphone is based on setup and/or hook switch status.

3.2 Rear Panel Connections

Figure 2 shows drawing of the rear panel of the C-2000. Each of the ports shown is discussed in detail in the following section.

3.2.1 Rear Panel Ports

Power Jack: The left most jack on the C-2000 is the Power Jack. The power supply that is included with the unit

plugs in to this location. It is a standard 2.5mm center positive plug and requires at least 12V to operate correctly.

Figure 2 Rear Panel Diagram

Line Port: The C-2000 is equipped with a single line jack. It is the second connector from the left. The connector is a

standard eight pin RJ -45. The pinout of the connector appears in Figure 3. The numbering of the pins are shown in Figure 3 for reference. In addition to the standard RX and TX pin pairs, the unit also can be supervised and supports cross mute functions. Pins 7 and 8 of the Line connector can be used as a form C closure relay for local control. Pins 7 and 8 form the closure during any PTT operation. An internal resistor makes an external connection to ground unnecessary, and can be removed to remove ground from the closure path.

Auxiliary Audio Input: The external 6 pin terminal block provides an Audio Input (1), PTT (2), and GND (6) line. Pulling PTT to ground activates the Audio Input line for transmitting audio from an external source. This input is a high impedance capacitance coupled input.

Auxiliary Speaker: Pin 1 of the AUX Port is a capacitance coupled low impedance output that can be used to drive an external speaker amplifier. Output level is controlled by the front panel volume control.

Battery backup: The +12V power input on the AUX Port is used for battery backup and is a diode-protected input. Earth Ground: The Earth ground connection on the AUX Port MUST be connected for proper operation. It provides

a path for any external noise to be shunted to. Data port: This port is a 0 to 10V asynchronous port used for cloning one C-2000 to another. The cable is not

supplied but the connector is. To connect two units, RX on one console should be connected to TX of the other console. Ground is connected straight through. This is a non-standard serial port used only for the C-2000 cloning function. Refer to 5.4.30 for details.

The Line interface for the C-2000 console provides communication with any standard tone remote system. Figure 4 shows the pin out of the line interface connector, which is on the rear panel (See Figure 2 and Figure 3).

4.2 FEATURE DESCRIPTION

4.2.1 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 that could occur, causing a loud squeal on the paralleled speakers.

Figure 5 Crossmute Function example.

Feedback may be avoided by muting the receive audio of the other consoles which are in parallel with a transmitting console. This may be accomplished by connecting pins 1 and 8 of each of the consoles to be crossmuted as shown in Figure 5. Pin 8 must be connected to provide a common ground. Figure 5 illustrates the connections between consoles 1 through 3 that are in the same room and when one transmits, the receive audio on the other consoles will be muted. Console 4 is off-site with no possibility of feedback, therefore, it is not connected and will not be muted.

Note: The intercom function will not work between crossmuted consoles.

4.2.2 U2 OPTO Isolator

U2, J18, J19 and J21 have been added to Main PBC rev B and tied in parallel to the X-Mute and Supervisory logic. Currently there is no programmed functionally within the unit and J18 and J21 should remain to the “B” position.

4.2.3 J22

J22 is a factory test jumper and not used in the field.

Figure 6 Supervisor Function Example.

The Supervisor Function enables a console, such as the C-1610, which has the capability to drive this line, to disable all units on a particular line. This includes both PTT and RX audio. Its connection is similar to that of the crossmute function. By wiring alone, it is possible to setup only specific consoles with this feature. Figure 6 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 from both Transmit and Receive. In addition, the C-2000 will display “SU” on the seven segment display if a master console, such as the C-1610, activates the Supervisor function.

4.2.5 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 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 setup mode. J20 allows for a circuit ground to be coupled to the relays common pin. “A” position = Grounded, “B” = Loop

4.2.6 Two-Wire/Fou r-Wire Mode

The C-2000 comes standard with a jumper selectable two or four -wire option. Note: The C-2000 is shipped in the fourwire mode. Two-wire mode is accomplished by the following jumper positions:

Two-Wire: Jumper Position

JP10 A

JP11 A Four-Wire: Jumper Position JP10 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.

4.2.7 RX Side Settings

In 4 Wire mode, the RX side is jumper selectable for a 600 ohm impedance or 10k ohm impedance. If only one console is on the line (no parallel consoles) then place J8 in the A position for a 600 Ohm line impedance. If more than one console is on one line, then place J8 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 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. In 2 Wire mode, all consoles should have J8 in the “B” position.

6 Vega’s C-2000

Console # J8 Position Impedance Impedance Loss (dB) 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 setup mode or adjusting the RX level POT inside the C-2000.

4.2.8 TX Side Settings

The C-2000 TX output circuitry has a DPDT relay that is used to connect and disconnect the TX output transformer from the TX line based on PTT status. This allows a very large number of consoles to be attached to the line in parallel, because only the transmitting unit will be directly connected to the line. When not transmitting, the DPDT relay is connected to 600 ohms or open circuit depending on the number of console connected in parallel to the line. If only one console is attached, this unit should have J12 in the “A” position. This makes it the effective master and terminates the line with 600 ohms. If there is more than one console connected in parallel, one console should be designated as the master by placing J12 in the “A” position. The remaining consoles should be designated as a slave and should have J12 placed in the “B” position. In this manner, the impedance looking back into the parallel configuration of consoles is still 600 ohms. Figure 7 shows the basic configuration. The C-1610 could also be the master in this configuration. NOTE: If any of the consoles connected in parallel are not C-2000’s, then all the C-2000’s should be configured as slaves. Additionally, J14 should be used as a TX line impedance correction if there are consoles other than the C-2000 connected in parallel. J14 position “B” adds another 600ohms to the output TX line. J14 Position “A” is straight through.

In a four-wire system with parallel consoles, the transmit line may be monitored. Refer to section 4.3.2, the monitor level setup on adjusting the level. The transmit monitor is not needed in two -wire mode as the transmit audio is already on the receive circuit. The transmit monitor, in 4 wire mode, is used to detect transmit activity for the TX Detect LED.

4.3 Level Adjustments

4.3.1 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.

Remote Control Console 7

Reference Description R171 TX Output Level Adjustment R105 Desk Microphone Adjustment R115 Hand Set Microphone Adjustment

MIC INPUT LEVEL ADJUST: Care should be taken to avoid overdriving the input TX circuitry, as this will distort the audio. Make sure you have enabled the desired Microphone connection in setup mode. Saying and holding the word “Four” is a good audio level test vocalization. Use a strong tone of voice.

When adjusting the Hand Set audio input level connect a oscilloscope to Test point TP3 and adjust R115. Speak into the Hand Set and adjust the audio to approximately 3.5Vp -p. A portion of the handset audio will be routed to the Hand set earpiece, this level is adjustable in setup mode.

For the Desk Microphone input, repeat the sequence only monitor Test point TP2 and adjust R105. Make sure that the Desk Microphone is at the normal distance from the operator when setting the level.

TX OUTUT LEVEL ADJUST: The transmit level potentiometer is used to adjust the output level of the transmit audio so that it is calibrated with the tone levels that were set in setup mode. Calibration of the TX line will vary depending on system variables as well as the number of consoles found in parallel on the line. A easy way to align the console for the correct level is to press and hold the PTT key. While the console is keyed up, the unit will by default be generating a Hold tone at – 20dBm. A meter reading dBm can then be used and R171 adjusted to read the correct value. Also a alignment tone, Section 5.4.51 Setup state 50 is provided (REV.2.3 and higher operating software).

4.3.2 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 press the intercom button. Adjust R104 until the level is comfortable in the handset/headset earpiece or the speaker. Make sure this feature is enabled or no audio will be passed. See Setup Mode.

4.3.3 RX Level Adjustment

The RX level should be adjusted so that the maximum level coming into the console use the entire range of the ADC, which is 0-4V. A test tone of +3dBm to -5dBm coming into the line interface is a good value to use. Adjust R89 so that the signal seen on an oscilloscope at Test point TP4 is approximately 3.8Vp-p.

5 Setup Mode

5.1 Entering Setup Mode

Entry into the C-2000 Setup mode is accomplished by pressing and holding the “IC-MON” keys, then pressing the “2” key. The IC and MON buttons will stay lit when in setup mode. If a PIN number is required, an “EP” will appear in the display requesting that the four-digit number be entered. If the number is entered incorrectly, the C-2000 will display “IP”, for incorrect PIN, and return to user mode. No PIN number is required if the system defaults are set.

Default values can be restored to the unit buy Pressing and holding the Function Up and Function Down keys when power is applied to the unit . If a PIN number has been set, it will be requested before resetting to default values, if the

PIN is entered incorrectly the C-2000 will not reset its values to default and will enter the user mode. PIN numbers can be enabled/disabled/changed in Setup Mode, see section 5.4.2. If the PIN number is lost or forgotten, a system override is available that will set all parameters back to default. To reset the system parameters, power down the unit. Open the case and disconnect the speaker. Next, place test jumper J17 in the “A” position and power up. This mode resets defaults and does a system test. The C-2000 has now stored system defaults, which includes no PIN number. Power down and place J17 in the “B” position. Connect the speaker, close the case and power up the unit.

5.2 Exiting Setup Mode

Exiti ng Setup Mode is done the same manner as entering Setup Mode. Pressing and holding the “IC-MON” keys, then pressing the “2” key will return the user to normal operation mode. Note, settings will be saved on exit. To save settings before exiting setup mode, press and hold the “IC” key and then press the “D” key.

5.3 Maneuvering Through Setup Mode

5.3.1 Setup Mode Control Keys

The main control keys are: VOLUME UP and DOWN: Selects the Setup State by scrolling up and down through the allowed states. FUNCTION UP and DOWN: Selects the Setup Option for the current Setup State by scrolling through the

allowed options for that state.

DTMF POUND KEY (#): Used as the Enter Key. Pressing this key will enter the current option for the

current state. It also takes you into a more complicated mode if more than a simple enable/disable is required.

DTMF STAR KEY (*): Used as the Escape Key. Pressing this key will exit without saving from certain

setup states that require it. Note: Only a few states use this key.

DTMF A and B KEYS: These keys are used to program Function Tone Frequencies main and sub-tone.

It is also used to select Clone mode Master or Slave.

IC and D KEY: Pressing and holding IC, then pressing D will save the changes made to Setup

Mode.

IC and MON KEYS: Pressing these keys together while in the PIN CHANGE state will disable the PIN.

Note: This key sequence is not used in any other state.

TRANSMIT KEY: This key is used to display the current Setup State, once the display has

changed to the setup option.

5.3.2 Setup Mode Philosophy

Once Setup Mode is entered, the operator will use the VOLUME UP and DOWN keys to select the Setup State. The Setup State is the system function that the operator wishes to change or enable. The display will show the Setup State number and both decimal points for 1 second and then change to the Setup State option number that is currently programmed, with no decimal point. If you wish to review the Setup State while the setup option is being displayed, simply press the TRANSMIT key on the front panel and the current Setup State will be displayed as long as the key is held. Once you have scrolled to your desired Setup State and the display has changed to that states currently programmed setup option, the operator can now use the FUNCTION UP and FUNCTION DOWN keys to scroll to the appropriate setup option. The display will show the setup option number and NO decimal points. The selection will only scroll to those option values that are available to that Setup State, i.e., an enable/disable Setup State will have option 1 and 2, with 1=enable and 2=disable and no other. Now pressing the ENTER (#) key will program the selected option for the current state. Once programming completes, the display will show “OC” for option changed, then display the current Setup State.

Saving the changes made to a Setup State is done by pressing and holding “IC” and pressing “D”. The display will show “SS” for saving settings, and then returns to the current Setup State. Exiting Setup Mode automatically saves the settings. If the settings are not saved and power is lost, the changes will be discarded.

There are certain Setup States that have more complex user interface features. These will be detailed in each Setup State section.

Each Function Tone has a main tone and one sub-tone. Once the user maneuvers to Setup State 10 using the VOLUME UP/DOWN keys, they will have to enter the Function Tone Frequency setup mode. Notice that, prior to entry, the FUNCTION UP/DOWN keys have no effect on the setup option. Function Tone Frequency setup mode has yet to be started.

12 Vega’s C-2000

To start Function Tone Frequency setup mode:

Press the ENTER (#) key with Setup State 10 as the current state. Notice that the display changes to “FF”, meaning Function Frequency, and stays that way until another valid key press occurs. The system is now in Function Tone Frequency setup mode.

To navigate in Function Tone setup mode:

In this mode, the FUNCTION UP/DOWN (56) keys are used to select the Function Tone the user wishes to modify. The allowable values are 1-99. Pressing FUP(5) or FDWN(6) will cause the display to scroll through these values, with no decimal point displayed. Once scrolling has stopped, the display will change

to setup option 1, with both decimal points displayed. Once the user has selected the Function Tone to be modified, use the VOLUME UP/DOWN keys to select

the frequency for the current Function Tone, based on Table 10. The display will scroll through the setup option numbers with both decimal points displayed. With the display showing the frequency setup option, the user can momentarily change the display to the current Function Tone selected by pressing and holding the TRANSMIT key. The current Function Tone will be displayed with no decimal points until the key is released, after which the display will return to the se tup option.

Once the user has selected the Function Tone and the frequency, programming can begin. Remember that each Function Tone has a main and a sub-tone. These are programmed by pressing DTMF “A” for the main tone or DTMF “B” for the sub-tone. Once the main or sub-tone has been selected, the display will show “OC” for Option Changed, then return to the current Function Tone number.

Exiting and saving the changes to the Function Tone Frequency setup mode can be achieved in the following manner: First, exit the Function Tone Frequency setup mode by pressing the Escape key (*). This will take you back to the entry point for Setup State 10. From here the user can navigate to any other Setup State. To save the changes, simply press and hold the “IC” key, then press DTMF “D”. The display will show “SS” for saved settings, then return the current Setup State.

range is –10dB to +10dB. See Table 18 for option examples. The values in between those shown in the table are valid as well, for example 12 would result in an output level of +1dB for the level setting.

5.4.30 Setup State 29 Clone Mode

Usage: Setup State 29 is used to copy the non-volatile memory of a properly

configured unit to a generic unit, thereby Cloning one unit to another. Note, the software version numbers must be the same.

This Setup State is the gateway to a more complex mode, so there are no setup options at first. The user will enter Clone Mode, first setup the Slave to receive data and then the Master to transmit data. Follow the detailed instruction below.

Make sure the two units are properly connected. The data port on the back of the C-2000 is a three pin port with TX, RX and GND. Using a three wire serial cable constructed as shown in Figure 8, connect the two units together. Keep the cable length reasonably short. Each unit will be shipped with the connector plugged into the back.

To Enter Clone Mode: Press the ENTER(#) key, the display will show “CL” for Clone Mode. The C-2000 is now waiting to be told

whether it will be the Master (TX) or the Slave (RX).

Clone Mode Operation: Place the Slave unit in receive mode by pressing DTMF “B”. There is no indication that the unit is in receive

mode. The Slave will wait indefinitely for the Master to being sending data. Once the Slave unit is ready to receive, the user may begin transmitting with the Master. Pressing DTMF “A” on the Master will start the transmission. After approximately 5 seconds, the Slave unit will receive the last packet, calculate the checksum and display “CC” for Clone complete or “EE” if the checksum fails. This concludes the cloning process.

20 Vega’s C-2000

6 Theory of Operation

The C-2000 is a Digital Signal Processor (DSP) based product. Because of this, many of the signals that once could be probed on older products, are handled within the DSP itself. This would include DTMF generators and decoders, notch filters, tone generators and decoders, and all of the audio summing. A great deal of the gain controls are included within the software of the DSP. There are four analog audio sections on the C-2000, they are: RX Input: Audio received on the line from an external source. RX Output: RX Input audio that has been sampled and processed by the DSP, then sent to a local speaker. TX Input: Audio from a local microphone, handset or auxiliary audio source. TX Output: TX Input audio that has been sampled and processed by the DSP, or internally generated

Tones/DTMF that is summed with TX Input audio. The result is routed to TX line out.

The following sections discuss the portions of the C-2000 that can be tested using a common oscilloscope and voltage meter by a qualified service technician.

6.1 Audio Input Paths

Audio can be input from four locations. These are the desk microphone jack (J5, RJ-11 modular), handset jack (J3, RJ12 modular), panel mic (built into keypad PCB), and the auxiliary connector (J4) on the rear of the unit. For each of these inputs, a single inverting Op -Amp gain stage exists to bring the level of the audio up to approximately 3.8Vp-p. This is the optimum level for the analog to digital converters (ADC). The trim potentiometers R115 and R105 set the audio levels from the handset and desk microphone jacks. All audio inputs, mentioned previously, share one half of the ADC (U25) with a CMOS switch (U4) used to route audio from the appropriate source to the actual input pin of the ADC. The auxiliary input (J4-4) is used to include an additional audio source into the transmit path. It has an integrated PTT (J4-2) input that when pulled low will select audio from this source for transmission. This input also utilizes a single inverting Op -Amp stage to set the input gain. The factory default setting is a gain of 1. If an external source or audio is to be used, its output level should be on the order of 3.5 Vp-p.

6.2 Audio Output Paths

All input audio, both RX input and TX input, is sampled by the DSP, processed, then sent to the Digit al to Analog Converter (DAC - U6) for export from the C-2000. U6 Pin 5 is the speaker audio source, U6 pin 8 is the TX output audio source. U5 is a CMOS switch that routes the audio to the desired location. U5 Pin 15, routes receive audio to the Handset/He adset for sidetone. U5 Pin 14, routes audio to the external speaker port. U5 Pin 4, routes audio to the main speaker. Each of these CMOS switches are followed by an op-amp used to buffer the audio and not overload the output driver of the DAC. Depending on the setup configuration, U5 acts as a muting mechanism, keeping audio away from disabled ports. U21 is a speaker driver that powers an 8-ohm panel mounted speaker. The audio source for U21 comes from U5, pin 4. TX output audio leaves the DAC and is routed to an Op -Amp stage for hardware gain control. The next stage is a differential driver circuit U10, followed by transformer T2 for transmission on the line interface. The first stage of the differential driver circuit has trim potentiometer R171 to fine tune the output level of the TX audio. The TX interface, after transformer T2, contains a DPDT relay K2 or K3, which allows the C-2000 to be tied in parallel with other consoles without creating a load on the circuit. When PTT is pressed the relay is energized and the TX output circuitry is connected to TX line out. J12 is a jumper that connects a 600-Ohm load to the line, when the TX output circuitry is disconnected from the line (no PTT). J14 sets the output impedance when the TX output circuitry is connected to the line (PTT active). For complete schematic details, refer to Section 8 the Specifications section.

6.3 Line Receive Path

The receive path enters through RFI protection circuits into transformer T1. Pot R89 is used to place the level of the receive audio into an optimal range for the ADC. A single gain stage is used to set the buffer the incoming audio (U24-7). The output of U24-7 is connected through a small first order filter network to the right channel of ADC U25.

The receive path also has a tie in to the transmit path. A differential configuration op-amp is used to provide the TXMonitor function. U24 pins 12 and 13 present a 1 Meg Ohm load to the TX line interface. This audio is then passed to R104 for level adjustment and into U24 pin 2 where it is fed to U27 Pin 3. U27 is a CMOS switch that allows the TX-Monitor function to be turned on and off.

Remote Control Console 21

6.4 System Clock Generation

The system clock is derived from a single 32.7680MHz Crystal Oscillator (Y1). The ADSP2185M DSP (U17) processor uses this clock to generate a 65.536MHz internal instruction clock rate. The system clock is routed to the Altera EPM7032AE44 PLD (U26) and divided into the signals necessary for audio processing. These signals include the MCLK (2.048MHz), SCLK (512kHz), LRCLK (8kHz) and FS (16kHz frame sync). Another signal generate by the PLD is B0 (U26-26). This signal is used by DSP software to sync the bit frames at start up. B0 is the inverse of LRCLK. U2631 is a clock signal that is the inverse of SCLK. The DSP serial port requires this signal, usually called the bit clock.

6.5 Non-Volatile Memory (EEPROM)

All the system configuration and parameter storage is maintained in the non-volatile memory of U18. The serial EEPROM AT24C16, has 16kbits of memory. The DSP writes and reads to the EEPROM via two of its Flag Pins.

6.6 User I/O

The Keypad and Seven Segment display are the main components to the User I/O scheme. The DSP controls the I/O with a series of register and latches (U11, U12, U15, U16, U30, U31). Chip Selects originate from the DSP, but are modified to their usable state by the PLD. The Chip selects are R-CS0,1(read) and W-CS0,1,2,3(write). They are generated by DSP signals RD, WR, IOMS and address lines A0,A1,A5.

6.7 Clone Mode Serial Port

The C-2000 can be used to copy the memory contents of one C-2000 to another. This is done with the serial data port on the back of the unit (J13). The circuitry used is a simple level conversion scheme to take the 3.3Vdc serial data stream from the DSP and convert it to a 10Vdc signal at the port. The port can only be used C-2000-to-C-2000. DSP pins 37,38 and 40 are a part of SPORT1 serial port. These signal are routed from U27 gate one and to Q30, then to the connector.

6.8 Power Regulation and Reset Control

Input power is a 12Vdc wall mount regulator. The input connector (J2) is a center positive, 2.5mm jack. It is connected to protection circuitry consisting of a fuse and dual diodes used to protect the source if auxiliary power is connected to J4. The system DC power requirements are 3.3V(U14), 2.5V(U7) for the DSP and 5V(U20), 10V(U28) for the analog circuitry. The system reset controller is the DS1233A (U13). U13 will momentarily hold the system in reset if the power fluctuates below VDD. There is a secondary 3.3V/2.5V supply that will be used based on parts availability and cost. U1 is a dual supply IC that generates 3.3/2.5Vdc and also has a reset control mechanism. If U1 is placed, then U7, U13, U14 and all associated components must be removed.
