The hardware

Front side

  • 1-14 - green LED signalized switched relay.
  • 15-16 - non used outputs.
  • white square - sign defines the type of equipment.

Back side

  • DATA - RJ45 input data connector for Band decoder
    1. - TXD (UART/232 dependency internal switch).
    2. - GND.
    3. - RXD (UART/232 dependency internal switch).
    4. - BCD-1 input.
    5. - BCD-2 input.
    6. - +5V DC power supply.
    7. - BCD-3 input.
    8. - BCD-4 input.
  • USB - +5V DC POWER supply, or upload arduino firmware.
  • ETHERNET - not used.
  • OUTPUTS - 14 relay outputs and GND.

How to connect Power

  • plug power via usb mini cable to AC adapter, computer or usb HUB

Firmware - General settings

  • Preset Band to output matrix - in default settings Band-1 corresponds to Relay-1, etc. You can sets any combination outputs for each band separate. With change zeros and ones in Matrix table. Band-0 reserved for out of range inputs measure.

Configure inputs

uncomment and activate only one input in source code

//=====[ Inputs ]=============================================================================================

// #define INPUT_SERIAL   // telnet ascii input - cvs format [band],[freq]\n (serial.h)
// #define ICOM_CIV       // read frequency from CIV (icom_civ.h) ** you must enabled 'CI-V transceive' in TRX settings, and disable ICOM_CIV_OUT **
// #define KENWOOD_PC     // RS232 CAT (kenwood_pc.h)
// #define YAESU_CAT      // RS232 CAT (yaesu_cat.h)
// #define YAESU_BCD      // TTL BCD in A  (yaesu_bcd.h)
// #define ICOM_ACC       // voltage 0-8V on pin4 ACC(2) connector - need calibrate in (icom_acc.h)
And connect to TRX as described below

Input Serial

Activate uncomment line 

#define INPUT_SERIAL

Not need any hardware settings, only send via USB to serial line ascii characters in preconfigured baudrate.

X,YYYYYYY\n

  • X - band output in range 0-14, if activate BCD output range is 0-10 because 11-14 reserved for BCD. 0 (zero) = no output will be turned on.
  • YYYYYYY - frequency in Hz - has no effect on the output relays, used if any CIV/CAT outputs activated.

ICOM CIV

Input worked in sniff mode (data over one wire - RXD). This means that it is necessary to provide, transmit frequency of TRX to serial line

  • enabled CI-V transceive in TRX menu settings
  • comunicate TRX with other device or software (for example logbook with CAT support)

Activate uncomment line 

#define ICOM_CIV

Requires baud rate and CIV address in setting section of source code

#define SERBAUD      9600    // [baud] Serial port in/out baudrate
#define CIV_ADRESS   0x56    // HEX Icom adress (0x is prefix)

In icom_civ.h file you can set rules to select individual output relays, with a resolution of one Hz.

            //=====[ Frequency (Hz) to Band rules ]======================================
            //                                        you can expand rules up to 14 Bands
            
                 if (freq >=   1810000 && freq <=   2000000 )  {BAND=1;}  // 160m
            else if (freq >=   3500000 && freq <=   3800000 )  {BAND=2;}  //  80m
            else if (freq >=   7000000 && freq <=   7200000 )  {BAND=3;}  //  40m
            else if (freq >=  10100000 && freq <=  10150000 )  {BAND=4;}  //  30m
            else if (freq >=  14000000 && freq <=  14350000 )  {BAND=5;}  //  20m
            else if (freq >=  18068000 && freq <=  18168000 )  {BAND=6;}  //  17m
            else if (freq >=  21000000 && freq <=  21450000 )  {BAND=7;}  //  15m
            else if (freq >=  24890000 && freq <=  24990000 )  {BAND=8;}  //  12m
            else if (freq >=  28000000 && freq <=  29700000 )  {BAND=9;}  //  10m
            else if (freq >=  50000000 && freq <=  52000000 ) {BAND=10;}  //   6m
            else if (freq >= 144000000 && freq <= 146000000 ) {BAND=11;}  //   2m
            else {BAND=0;}                                                // out of range

  • short JP2 (RXD)

KENWOOD CAT

Input worked in sniff mode (data over one wire - RXD). This means that it is necessary to provide, transmit frequency of TRX to serial line

  • comunicate TRX with other device or software (for example logbook with CAT support)
  • activate function Frequency request which utilizes data output TXD, and prevent the use of any from CAT/CIV output.

Activate uncomment line 

#define KENWOOD_PC

Requires baud rate in setting section of source code

#define SERBAUD      9600    // [baud] Serial port in/out baudrate
// #define WATCHDOG       10  // [sec] determines the time, after which the all relay OFF, if missed next input data - uncomment for the enabled
// #define REQUEST            // use TXD output for sending frequency request (Kenwood PC, Yaesu CAT)

You can also use functions

  • WATCHDOG - determines the time, after which the all relay OFF, if missed next input data
  • REQUEST - use TXD output for sending frequency request - and prevent the use of any from CAT/CIV output.

In kenwood_pc.h file you can set rules to select individual output relays, with a resolution of one Hz.

        //=====[ Frequency (Hz) to Band rules ]======================================
        //                                        you can expand rules up to 14 Bands
        
             if (freq >=   1810000 && freq <=   2000000 )  {BAND=1;}  // 160m
        else if (freq >=   3500000 && freq <=   3800000 )  {BAND=2;}  //  80m
        else if (freq >=   7000000 && freq <=   7200000 )  {BAND=3;}  //  40m
        else if (freq >=  10100000 && freq <=  10150000 )  {BAND=4;}  //  30m
        else if (freq >=  14000000 && freq <=  14350000 )  {BAND=5;}  //  20m
        else if (freq >=  18068000 && freq <=  18168000 )  {BAND=6;}  //  17m
        else if (freq >=  21000000 && freq <=  21450000 )  {BAND=7;}  //  15m
