  • Page 4: General Information

    GENERAL INFORMATION Midian’s TRC-1000 is a tone remote controller with multi-format dialing for selective calling. The TRC uses EIA and Industry standards for monitor, guard, and F1-F16 function tones. Midian also adds F17 for additional function control when used with Midian’s TTC-1. The built-in display shows the frequency/function selection, real- time clock and the encoding sequence.

  • Page 5: Hardware Installation

    HARDWARE INSTALLATION Be certain to follow standard anti-static procedures when handling any of Midian’s products. Getting Started: The TRC has a number of adjustment potentiometers and configuration jumpers. These have been adjusted and configured at the factory for a typical installation. However, audio levels should be verified and adjusted (if necessary) at the time of installation.
  • Page 6 4-Wire & Line 1 Operation: For a single line 4-wire installation, connect pins 4 and 7 (black and yellow) for receive audio and pins 5 and 6 (red and green) for transmit audio. For this feature TRC Option F must be installed in the TRC.

  • Page 7: Hardware Alignment

    HARDWARE ALIGNMENT The following procedures assume a good quality dedicated line is being used and the tone remote adaptor is already installed. The alignments are preset at the factory and should not need to be adjusted during installation. However, if an adjustment is needed please follow the procedures below.

  • Page 10 SEND: Pressing SEND will transmit the high-level guard tone for 120 msec, followed by the frequency tone for 40 msec, followed by the low-level guard tone that keys the radio with the voice and dialing riding over the low-level continuous tone. 0-9 Keys: Used in conjunction with the FREQ key these number keys can be used to select the frequency/function tone.

  • Page 11: Operation

    OPERATION The TRC-1000 has 3 operating modes: Control Mode: This is the normal operating mode. It allows for remote control of a base station equipped with a tone remote adaptor such as Midian’s TTC-1. Call Mode: This mode is for encoding DTMF, 5-Tone, 2-Tone or Pulse Tone.
  • Page 12 Receiving: When a field radio keys up, the tone remote adaptor passes the voice down the line to the TRC. The voice will then be passed through to the internal speaker of the TRC. Intercom: Pressing the INTER key activates the Intercom function. Press and hold the INTER key to call other remotes on the line without keying the base station.

  • Page 14 Navigating the Menus Press the key MENU key while in Control to place the unit into Menu Mode. Upon entry to Menu Mode, you will be in the Main Menu. The top line of the display indicates this. The bottom line displays an item available for selection.
  • Page 15 Entering Special DTMF Digits: The TRC supports the following special DTMF 'digits' in numeric entry mode: *, #, A, B, and C (D is not supported). These are entered using 2-key sequences as follows: * = * * # = * # A = * 1 B = * 2 C = * 3...
  • Page 16 The following sections describe the various functions of the menu system. Shortcut keys are shown for those menu items that have shortcuts. Factory default settings are shown underlined. CALL <0> When the call command is selected you will be prompted to enter a user ID. You can either enter a unit ID or scroll right to enter into the database.
  • Page 17 SETUP menu SET DATE/TIME <2> In order for the correct date and time to be displayed, the real-time clock must be set.

Printer Option: The TRC, if ordered with the printer cable option, can log the pages to a serial device. The printer must have a print buffer and a standard RS-232 port. It must be configured for 9600 baud, 8 data bits, 1 stop bit and no parity.
  • Page 19 PAGER SETUP <6> This section allows you define up to 10 different pager types. There are 10 pager profiles consisting of the fields described below. Each profile has a factory default setting intended as examples to follow. Profile Name field: This can be any alphanumeric string up to 14 characters. The name can be chosen based on the pager description such as ‘MOT PLAN L’...

O FF Disable security feature Enable security feature Password: Sets the password used to unlock the menu system when the security is enabled. Must be 4 numeric digits.
  • Page 23 When to Send setting: Select when the frequency/function tone is sent. The options are as follows: AFTER SEND: The tone will be sent after high level guard tone every time the SEND key is pressed and ONLY after the SEND key is pressed. Therefore this setting is applicable only when the tone is used only for TX frequency control.
  • Page 24 UTILITIES menu <9> Generate LLGT: Causes the TRC to generate low-level guard tone continuously until told to quit. This utility may be also be used to adjust the TX audio level. Press CLR to stop tone generation when done. Gen Test Tone: Causes the TRC to generate high level guard tone followed by a function tone. After that, a 1007 Hz test tone along with low-level guard tone will be generated for 10 seconds.

  • Page 25: Tone Signaling Formats

    TONE SIGNALING FORMATS Signaling Format Compatibility In tone remote systems, the industry standard 2175 guard tone is filtered out by the tone remote adapter at the base station so that it is not heard over the air. This filter can affect signaling tones close to 2175 Hz. Tones within +/-70 Hz could be attenuated to a level such that they cannot be decoded by receiving equipment.
  • Page 26 Tone Encoding Tables Entering a user ID number, often called a CAP code, is straightforward for most of the encoding formats supported by the TRC. For example, when encoding DTMF or 5-tone, the digits 0-9 are simply typed in directly. Some formats do not allow for this straightforward approach.

  • Page 28: System Error Messages

    SYSTEM ERROR MESSAGES DATABASE EMPTY Reason: An attempt was made to edit or delete a user when the database was empty. Solution: These functions do not apply when the database is empty. DATABASE FULL Reason: An attempt was made to add a user to the database and there is no more room. The maximum number of user aliases of 128 cannot be exceeded.
  • Page 29 SPEED DIAL EMPTY Reason: You have pressed a speed dial number, but there is no user associated with it. The user may have been deleted, or no association was ever made. Solution: Go to speed dial setup and associate a user in the database to the speed dial number. INVALID CAP CODE Reason: The number of digits in the CAP code are incorrect for the pager format being used.

  • Page 30: Theory Of Operation

    THEORY OF OPERATION Initial Power-up: Upon power-up the TRC defaults to Frequency 1 when the [SEND] button is pressed. Analog Circuit RX Audio Input Path: RX audio from a tone remote adaptor at the remote site travels down the phone line to the RJ-11 line interface connector PL-1.
  • Page 31 Digital Circuit There are three microprocessors on the digital schematic page. U402 controls the keypad interface and also talks to the LCD. In addition it generates the keyboard beeps to the speaker amp, it controls the speaker mute when the handset is taken off-hook. Additionally, it controls the Line 2/Supervisor to the line relay on the analog page. Microprocessor U401 generates the Guard Tone, function tones and signaling tones on its B0-B7 port.
