Manual IP switch MK2 is delivered with two parts - IP relay diver KIT (needs to assemble) and assembled IP control. Both parts have firmware installed and automaticaly pair in local network with available DHCP server.

Quick start guide in two step

  1. IP Switch relay driver KIT
    • Assembly KIT by this instructions.
    • Connect ethernet to local LAN with available DHCP server
    • Connect 5V power DC adapter
    • Set NET-ID-sufix with BCD switch in the range 0-7, for example 0.
  1. IP control
    • This part is assembled and tested.
    • Connect ethernet to local LAN with available DHCP server
    • Set NET-ID-sufix with bottom side BCD switch in the range 0-7, the number must be the same as on IP-switch relay driver.
    • Connect micro USB cable for power supply.
    • Wait to pair and start to use.

The hardware

  • IP Switch relay driver KIT is on its own page.
  • IP control

  • 1 - rotary Encoder switch one from 2-16 outputs
  • 2 - status LCD display
    • Points in the first row indicate the scope of the encoder.
  • 3 - NET-ID BCD, switch sufix in range 0-7
  • 4 - 25 pin D-SUB (inputs outputs not use)
    • PIN-1 DC power, typicaly 13,8V from transceiver
    • PIN-18 PTT input
    • PIN-14 GND
  • 5 - Ethernet
  • 6 - micro USB for upload firmware or power
  • 7 - eight light button - light after receive confirming from remote relay

Firmware

  1. Download and install Arduino IDE 1.8.3 od older
  2. Install library
    1. Wire
    2. LiquidCrystal_I2C or LiquidCrystal_PCF8574
  3. Download Band Decoder 2 firmware source from GitHub
  4. Preset two jumper in P10/P11 pin geader
  5. Connect micro USB cable between band decoder and PC
  6. Configure... (more in the chapter Configure TRX inputs)
  7. Select menu Tools/Board:"Arduino Nano"
  8. Select menu Tools/Port/YOUR-CONNECTED-PORT
  9. Upload firmware

LCD display

❏ I2C display need preset address in firmware

#define LcdI2Caddress  0x3F

The most common are values 0x27 or 0x3F.

Select I2C LCD chip
  • If type of chip is PCF8574AT
    • Install library LiquidCrystal_I2C
    • Disable line 
      // #define LCD_PCF8574T
  • If type of chip is PCF8574T
    • Install library LiquidCrystal_PCF8574
    • Enable line 
      #define LCD_PCF8574T

❏ Preset LCD contrast with potentiometer on rear side LCD module

CONFIGURE OUTPUTS

You can uncomment more than one output, but not all combinations are worked.

Always usable - may all at once.

Only one from (not available during active Frequency request option (available only one TXD line)

//=====[ 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 REQUEST **
// #define YAESU_CAT_OUT      // send frequency to RS232 CAT ** for operation must disable REQUEST **

8 output driver

  • Allways enabled.

How to expand outputs

Band decoder use internal shift register with 8 outputs. This is free expandable. You can connect next shift register to P5 output connector. Schematics module for serial chain linkink on picture.

And sets number of all shift register in firmware

  • internal = 1
  • internal + one external =2

int NumberOfBoards = 2;    // number of eight byte shift register 0-x

SERIAL ECHO

Activate uncomment line 

#define SERIAL_echo

Requires setting 

#define SERBAUD  9600

YAESU BCD output

Always activate - except enable BCD input.

You can set rules to select BCD output, dependency to detected band input.

  • Upload firmware
  • Preset RXD P11 dependency to connected transceiver
    • 232 for RS232 communications
    • TTL for 5V level data
  • Preset P10 to USB
  • Open arduino terminal, and set same baudrate by firmware preset
