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

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 CAT CIV

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 JP1 JP2

ICOM ACC(2) voltage

Hardware

  • short JP3

Software

  • uncommented
    #define ICOM_ACC
  • calibrate voltage in icom_acc.h

Yaesu BCD

Hardware

  • all open

Software

  • uncommented
    #define YAESU_BCD
  • optionaly set BCD matrix in yaesu_bcd.h

Kenwood CAT

Sniff mode

Comunicate trx only with banddecoder

Configure outputs

You can uncomment more than one output, but not all combinations are possible. See on Context table and description of parts.

//=====[ Outputs ]============================================================================================

// #define SERIAL_echo          // Feedback on serial line in same baudrate, CVS format <[band],[freq]>\n
// #define ICOM_CIV_OUT         // send frequency to CIV ** you must set TRX CIV_ADRESS, and disable ICOM_CIV **
// #define KENWOOD_PC_OUT       // send frequency to RS232 CAT ** for operation must disable KENWOOD_PC and REQUEST **
// #define YAESU_CAT_OUT       // send frequency to RS232 CAT ** for operation must disable YAESU_CAT and REQUEST **
// #define BCD_OUT              // output 11-14 relay used as Yaesu BCD

Firmware - General settings

Source code need configure in three steps

1. Select Inputs

  • SERIAL terminal
  • ICOM ACC voltage

. ICOM CI-V (optionally sniff mode)

. KENWOOD - CAT (optionally sniff mode)

  • YAESU BCD

2. choose settings

3. 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.

//=====[ Settings ]===========================================================================================

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

//=====[ Sets band -->  to output in MATRIX table ]===========================================================
