  • Page 8: Theory Of Operation

    THEORY OF OPERATION INTRODUCTION Great care was taken in the design of your controller to make it "installer-friendly." Audio and logical interfaces were made as universal in nature as possible, so that a minimum of external hardware is needed to complete the installation. Although the controller's "engine" is a powerful microprocessor, the command language is designed to be easy-to-learn and flexible.

  • Page 9: External Device Interfacing

    several CTCSS modes via DTMF commands. 2nd RECEIVER INTERFACING An additional receiver can be interfaced to your controller, which can act as either a link receiver or a control receiver. If a 2nd receiver is used, the controller requires a minimum of two additional connections.

    frequency in the range of 100 Hz to 3000 Hz, with an accuracy of a few Hertz. CW amplitude and paging amplitude are separately adjustable with pots. DTMF characters are generated via the encoder portion of the MT8880 DTMF Transceiver IC. DTMF paging amplitude is pot-adjustable.

  • Page 11: Installation

    INSTALLATION INTRODUCTION You will need to prepare either one or two cables for your 6K controller. One cable is for DC power, and is terminated with the 2.5 mm power plug provided. Since DC power may be supplied to the 6K via the other cable if desired, this first cable is optional.
  • Page 12 RECEIVER #1 (REPEATER RECEIVER) COR Your 6K controller requires a logic signal, generated by your repeater receiver, which becomes active when an incoming carrier is detected. This logic signal is usually called "COR" (Carrier Operated Relay) or "COS" (Carrier Operated Switch), and is usually generated by the receiver's noise-operated squelch circuitry.
  • Page 13 voltage is normally higher than 5 V and is pulled down by the controller, or if the receiver COR cannot pull down the input below 2 V, then you should clip one lead of the pullup resistor and lift it from the board to prevent its making contact.

  • Page 14: Repeater Transmitter Ptt

    REPEATER TRANSMITTER PTT Your transmitter requires a "PTT" (Push-to-Talk) signal from the controller. When this signal becomes active, the transmitter will key (transmit). At this point, it is unimportant whether your transmitter's PTT input is "low active" or "high active", since the controller has sense-reversal dipswitches (discussed later).
  • Page 15 RECEIVER #1 (REPEATER RECEIVER) AUDIO The controller requires audio from your repeater receiver, which should be connected to pin 13 of To get a better idea of how to interface your particular receiver's audio output to the controller, let's examine the controller's Receiver #1 audio input circuit. This circuit consists of op amp U22D connected as an AC-coupled inverting amplifier with two feedback resistors and one feedback capacitor.

  • Page 16: Repeater Transmitter Audio

    REPEATER TRANSMITTER AUDIO Your transmitter will require audio from the controller. Connect the transmitter's audio input to pin 11 of the J2 connector on the controller. To get a better idea of how to interface your particular transmitter's audio input to the controller's audio output, let's examine the circuit used in the controller to drive the Transmitter Audio Output.

  • Page 17: Repeater Ctcss Decoder

    REPEATER CTCSS DECODER CTCSS, or Continuous Tone-Controlled Squelch System, is a convenient problem solver for users and owners in many parts of the country where the bands are overcrowded with repeaters and RFI. In addition, your controller allows CTCSS to be required as a qualifier for entering DTMF commands, thus increasing the security of the repeater system.
  • Page 18 RECEIVER #2 (CONTROL/LINK RECEIVER) COR Your controller can be interfaced to a second receiver, if desired. This receiver can serve a number of applications, depending on your needs. Paths can be "set up" or "knocked down" between Receiver #2 and three devices: The transmitter, the DTMF decoder, and the phone line. Path control is done by DTMF commands.
  • Page 19 RECEIVER #2 (CONTROL/LINK RECEIVER) AUDIO If you decide to add a second receiver, the controller will require audio from it. RX2 Audio should be connected to pin 12 of the controller's J2 connector. The controller's RX2 Audio input circuitry is designed exactly like the RX1 Audio input. The op amp in this case is U22C, and the level adjust pot is R76.
  • Page 20 RECEIVER #2 (CONTROL/LINK RECEIVER) CTCSS DECODER If you decide to add a second receiver, you have the option of adding a CTCSS decoder to it. After installing the decoder into the receiver, connect the decoder's logic output to pin 16 of the controller's J2 connector.
  • Page 21 PTT line, was enabled at the time, then the transmitter could stay keyed until the power source failed. Your S-COM controller will cease microprocessor operation when the power supply voltage fails, but it will also force the digital outputs off at that time. This condition will be held until the power source voltage drops considerably lower.

  • Page 22: Logic Inputs

    LOGIC INPUTS Your 6K controller has the ability to monitor "logical" devices at the repeater site. "Logical" devices are sensors, switches, relay contacts and other devices that have an off/on output. The controller has three logic inputs dedicated to this purpose. Also, the two receiver COR inputs and the two CTCSS decoder inputs can serve as additional logic inputs.

  • Page 23: Logic Outputs

    LOGIC OUTPUTS Your 6K controller has the ability to control "logical" devices at the repeater site. "Logical" devices are relays, lamps, solenoids, IC logic, and other devices that are turned ON and OFF. The controller has three logic outputs dedicated to this purpose. Logic output #1 is pin 7 of J2.

  • Page 24: Telephone Line Connection

    13. TELEPHONE LINE CONNECTION If your controller is equipped with the Telephone Interface Module, you can connect the controller to the telephone network. The 14-foot cable supplied with your controller has a modular USOC (Universal Service Order Code) plug on each end. This plug mates with a USOC RJ11C jack. Connect one end of the cable to the controller, and the other end to the RJ11C jack at your repeater site.

  • Page 27: Signal Name

    INPUT/OUTPUT CONNECTOR SUMMARY Both the 5K and the 6K models have DB25S (25-pin female D-subminiature) connectors on the main PC board. You may use the mating DB25P (male) connector (supplied) to build a cable, or you may purchase the optional pre-assembled cable. The cable will connect the controller to your repeater and auxiliary equipment.
  • Page 28 POTENTIOMETER SUMMARY The 6K Main Board is designed with 8 potentiometers. These pots adjust audio levels only. Tone frequencies, CW sending speed, and other parameters are digitally controlled and are remotely adjusted with DTMF commands. Therefore, the pots will only have to be adjusted when installing the controller, or when replacing the equipment to which the controller is interfaced.

  • Page 29: Switch Summary

    SWITCH SUMMARY The 6K Main Board has two switch assemblies, S1 and S2. S1 is a momentary pushbutton switch used to initialize the controller. The procedure that must be used to initialize the controller is described later in this manual. S2 is a 6-pole dipswitch array.

  • Page 30: Getting Started

    GETTING STARTED INTRODUCTION In this section, we will assume that you have either completed the installation of the controller into the repeater, or you are simulating a repeater with switches for COR signals, LEDs for PTT loads, and so on. If desired, the controller can be programmed on your workbench, then moved to the repeater site for installation.

  • Page 31: Power On/Initialization

    POWER ON/INITIALIZATION Each time power is applied to the controller, it will check to see if the Initialize pushbutton is being pressed. (The Initialize pushbutton is located in the right rear corner of the Main Board). At that moment, the controller will decide whether to retrieve default information stored in the EPROM and write it into the non-volatile RAM (pushbutton down), or retain the previously-stored information (pushbutton up).

  • Page 32: Testing The Controller-To-Repeater Transmitter Interface

    TESTING THE CONTROLLER-TO-REPEATER TRANSMITTER INTERFACE Apply power to both the controller and the repeater while monitoring the repeater with an extra receiver. When power is applied, the transmitter should key and send the reset CW message. If the transmitter does not key at all, check the wiring. Both the controller and the repeater should be powered up.

  • Page 33: Testing The Controller-To-Repeater Receiver Interface

    TESTING THE CONTROLLER-TO-REPEATER RECEIVER INTERFACE Generate an RF signal on the repeater's input frequency. The controller should key the repeater transmitter. When the signal disappears, a short courtesy beep should be heard. The transmitter should stay keyed for a few more seconds, then it should unkey. If this does not happen, check the wiring between the repeater receiver's COR driver and the controller's Receiver #1 COR Input.

  • Page 34: Testing The Dtmf Decoder

    TESTING THE DTMF DECODER Introduction Your controller uses an 8880-type DTMF Transceiver IC. This crystal-controlled device encodes and decodes all 16 DTMF digits. It has an extremely wide dynamic range (30 dB), and can detect digits that have as much as -6 dB to +6 dB of twist. ("Twist" refers to the difference in amplitude between the two individual tones that are summed to make up a DTMF digit.
  • Page 35 Check to see if a command was entered to disable the DTMF decoder from the repeater receiver. Falsing Some user's voices can contain frequency components that appear as DTMF digits to the decoder. If such a digit is detected, "falsing" is said to occur. If the DTMF Muting feature is enabled, then the result of falsing is the loss of repeat audio for a syllable or two.

  • Page 36: Programming Fundamentals

    PROGRAMMING FUNDAMENTALS INTRODUCTION You program the controller by entering strings of DTMF digits. These strings of digits are referred to as commands. A standard DTMF keyboard with 12 digits may be used for nearly all commands. A few advanced features are available to programmers with 16-button keyboards. The extra four lettered keys may be used in passwords or macro names to increase the security of the system.

  • Page 37: Response Messages

    99 70 123 * We've put spaces between some digits to help explain this example. You do not need any pauses between digits when you are programming the controller. The password in this example is 99, the default password. The password tells the controller that you are a legitimate programmer.

    have finished entering a command. The "*" will always work as a terminator. You can also allow a carrier drop to work as a terminator if you wish; the carrier drop method can be turned on and off, but the "*" method can't be turned off, and will terminate any command. Why do we have the two methods? It's easier to terminate a command by simply releasing the PTT (push-to-talk) button on your microphone, and you have saved one keystroke (the "*").
  • Page 39 burst (caused by the beginning of the first digit). If you wait too long between digits, the muting will end. The next digit you enter will cause a short burst at the beginning. The Mute Delay Timer initially defaults to 0.5 seconds, but it can be reprogrammed with a different value if desired. 6K V1.02 03-16-91...
  • Page 40 MESSAGES INTRODUCTION Your controller uses messages to communicate with both the users of your repeater and the programmers of the repeater controller. Messages may be composed of combinations of CW (Morse) characters, beeps, DTMF characters, and various paging formats. Most of the controller's messages are remotely programmable via DTMF commands.
  • Page 41 MESSAGE THEORY OF OPERATION The controller uses a large area of memory, called the Message Buffer, to temporarily store the messages that it is asked to send. The Message Buffer is a "FIFO" buffer (First-In, First-Out), which means that the first message to arrive is the first one sent out. The purpose of the buffer is to prevent overruns when several software programs need to send messages simultaneously.

  • Page 42: Message Control Characters

    MESSAGE CONTROL CHARACTERS All Control Characters are four (4) digits long, and always begin with 99. The 99 tells the Message Handler that special instructions follow. The next two digits contain those special instructions. The Control Characters that have been defined to date are: CONTROL CHARACTER DEFINITIONS 9900 CW Characters follow...
  • Page 43 CW MESSAGES A. Control Character The Control Character 9900 should be entered before the actual CW characters when building a CW message. If a message does not begin with a Control Character, the Message Handler will assume that the message should be sent in CW. Therefore, a CW- only message would not require the 9900.
  • Page 44 At the end of a CW message, the Message Handler will change the frequency back to normal. This allows you to create a special CW message with a unique pitch, and not worry about changing the frequency back to normal to prevent affecting later messages. If you wish to change the CW frequency for ALL CW messages, see the CW Frequency Control Command.

    TONE CODES When entering tone frequencies for CW, beep, or paging messages, a tone code is required. A tone code is a 4-digit number that may be either taken from the Tone Code Table or calculated.

  • Page 120: Quantity Of Macros

    MACROS INTRODUCTION A very powerful feature of the controller is its ability to handle “macro commands”. No macros exist until you create them. You create macros with a command that sets aside a storage area, names it, and puts your desired command into it. You can then append additional commands, erase it, list its contents in CW, and rename it.

  • Page 121: Macro Execution

    MACROS MACRO EXECUTION When a macro is executed, the individual commands within that macro are executed in the order they were stored. For example, if a macro contains three commands that send CW messages, then the messages will be sent in the order they appear in the macro. If this macro contains another macro, then the nested macro will be fully executed before the controller continues on with the remaining commands in the original macro.

  • Page 122: Append To Macro

    MACROS APPEND TO MACRO Command Form: (PW) 29 (macro name, command) * Description: This command is used to attach an additional command to a macro.

  • Page 165 This is the end of the V1.02 manual. V2.0 upgrade information follows. (If your 6K isn’t V2.0, you can upgrade it with a low-cost kit from S-COM.) Thank you for purchasing the 6K Upgrade V2.0! Enclosed you will find: • A replacement RAM that also contains a battery and clock/calendar.
  • Page 166 NOTE: Along with the new features mentioned in the following pages, please note these additional improvements in V2.0: The number of macros has been increased from 200 to 280, and the maximum storage capacity of each macro has been increased from 54 to 100 characters. The Message Routing Codes have been improved so that you can decide whether a message should be mixed with receiver audio.

  • Page 186 Run-Time Variables Run-Time Variables (RTVs) are small code groups that you place into a message to be expanded at “run time” (the instant the message is actually transmitted by the controller). The message handler recognizes run-time variables because they always begin with 98. When the message handler encounters an RTV, it forms the appropriate message and transmits it in place of the RTV code.
  • Page 187 Scheduler The 6K Controller features a powerful Scheduler program that accepts up to 100 time/date Setpoints. Each setpoint can be programmed to execute a macro based on the month, day-of-month, day-of-week, hour, and minute of the real-time clock and calendar, e.g. midnight, December 31st. Wildcards can be used to program recurring setpoints, e.g.
