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
- 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.
- 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
Circuits
- Based on universal NANO module
- And expanding light keypad

Firmware
- Download and install Arduino IDE 1.8.3 od older
- Install library
- Wire
- LiquidCrystal_I2C or LiquidCrystal_PCF8574
- Download Band Decoder 2 firmware source from GitHub
- Preset two jumper in P10/P11 pin geader
- Connect micro USB cable between band decoder and PC
- Configure... (more in the chapter Configure TRX inputs)
- Select menu Tools/Board:"Arduino Nano"
- Select menu Tools/Port/YOUR-CONNECTED-PORT
- Upload firmware
LCD display
❏ I2C display need preset address in firmware
#define LcdI2Caddress 0x3F
The most common are values 0x27 or 0x3F.
- If display dont work
- Upload I2C scanner firmware
- Open terminal Ctrl+Shift+M
- Write detect addres to band decoder firmware
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
