  • Page 7: Introduction

    The C-2002 will accommodate a desk microphone along with a handset (or headset) as indicated on the side of the C-2002 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.

    Mute functions, DTMF keypad, Supervisory, Alert, Channel and ALT functions used with the F1-F8 Function Tone selection. The C-2002 is programmed from the front panel using the four gray soft keys located below the Vacuum Florescent LCD display provides channel/numeric indication, clock and audio-level meter.

    2.2 Rear Panel Connections Figure 2 shows drawing of the rear panel of the C-2002. Each of the ports shown is discussed in detail in the following section. 2.2.1 Rear Panel Ports Power Jack: The left most jack on the C-2002 is the Power Jack.

  • Page 10: Figure 3 Rear Panel Pinout

    Data port: This port is a 0 to 10V asynchronous port used for cloning one C-2002 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.

  • Page 12: Line Setup And Description

    4 Line Setup and Description 4.1 INTRODUCTION/DEFAULTS The Line interface for the C-2002 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).

  • Page 13: Supervisor Function

    1 2 3 4 5 6 7 8 The Supervisor Function enables a console, such as the C-2002, 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.

  • Page 14: Tx Side Settings

    Additionally, J2 (Line 1) or J4 (Line 2) should be used as a TX line impedance correction if there are consoles other than the C-2002 connected in parallel. J2 (Line 1) or J4 (Line 2) position “B” adds another 600ohms to the output TX line.

  • Page 15: Level Adjustments

    Remote Control Console 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.

  • Page 16: Hardware Overview

    The C-2002 is a Two-line, multi-mode console designed specifically for small to medium level system requirements. All functions are housed in a single small modern looking console. 5.1 C-2002 Console The C-2002 consists of the following sub-assemblies enclosed in the single case: Main Processing Board, Keypad PCB and Display. 5.1.1 Main PCB The Main PCB is mounted to the bottom of the enclosure using 4 #6 screws.

  • Page 17: Theory Of Operation

    6 Theory of Operation The C-2002 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.

  • Page 18: System Clock Generation

    6.7 Clone Mode Serial Port The C-2002 can be used to copy the memory contents of one C-2002 to another. This is done with the serial data port on the back of the unit (J3). 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.

  • Page 19: Setup Mode

    7 Setup Mode 7.1 Tech Mode The tech mode allows a technician to program the internal settings of the C-2002 console. The tech mode is entered by pressing simultaneously. The technician will be required to enter a PIN number to allow entry.

    Remote Control Console DTMF string is received. After this period of time, the line is no longer unselected, but will blink until the console operator performs a PTT operation on the line. The value for this duration is setup using the Prog1. The edit screen allows the value to be increased and decreased in increments of one second.

  • Page 33: Automatic Gain Control (Agc) Enable/Disable

    This option is used to enable DTMF ANI Decode. This function is used in conjunction with the DSP223 tone adapter and the Kenwood TK-x150 mobile radio. The Fleetsync ANI is sent down the line to the C-2002 in DTMF format. The DTMF ANI is decoded and displayed. For more information, refer to the DSP-223 Technical Manual, Telex Communications Part Number 803274 Rev D or higher.

  • Page 34: Incoming Select Call Dtmf String Setup

    7.7.2 Incoming Select Call DTMF String Setup The C-2002 has the capability of recognizing 3 different incoming DTMF strings on any line, monitored or not. When this programmable string is decoded, the unit will Un-mute the line for a programmable period of time (see Select Call Timer Duration Setup) to allow the remote user the opportunity to make a short transmission which the console operator can monitor.
