6x2 Antenna switch control

How to connect Power

• Plug DC jack 5,5 outer, 2,1 mm inner size.
• Connect 12-15V DC power voltage. Current dependency to connected antenna switch, alone controller about 60mA.

Front side

• LCD - shows selected antenna - first line Input/Output 1, second line Input/Output 2
• MENU - light button. For activate press button more than 0,5 second. Green light signals if manual control activate.
• ENCODER - rotary encoder primary move cursor, after activate MENU you can select antenna outputs manual or back activate BCD inputs.

Rear side

• DC POWER - input jack 5,5/2,1 mm size for DC power between 12-14 Volts. Same Power on pin8 ANT outputs.
• ETHERNET - OPTIONAL module for controlled switch manual over simple web page.
• microSD - not implemented.
• BCD IN - band data inputs activate two levels, dependency to JP8 jumper
• HIGH - TTL voltage input
• LOW - grounded input (contains own 1k pull up resistor)
• PTT TRX - grounded activate input PTT from transceiver (contains own 1k pull up resistor)
• PTT PA - PTT continues from TRX to this output for power amplifier. If detect collision between inputs band, this output will be deactivate.
• ANT - six outputs, will be in two levels dependency to preset JP1 and JP2 jumper. Also 12V DC power and ground available.
• ULN if use internal driver ULN2803A - open collector 500 mA each outputs
• UDN if use internal source 12V power driver UDN2580A.

Left side

• From the left side is accessible USB mini connector from Arduino NANO, which is usable for upload new firmware.

LCD contrast

• with potentiometer RV1 - near left side LCD module

Inputs BCD Levels

• JP8 to HIGH - activate BCD inputs with TTL signal level (1k ohm pull-down resistor).
• And uncoment line in firmware

  #define inputHigh          // enable input High level (default)

• JP8 to LOW - activate BCD inputs to ground (1k ohm pull up resistor).
• And coment line in firmware

  //#define inputHigh          // enable input High level (default)

Outputs Antenna switching

This jumper must be set dependency to used U4 and U7 IO chip - do not change before change chip!

ULN - for ULN2803A open collector driver - switching antenna relay with grounded outputs.

UDN - for UDN2580A source 12V power driver - switching antenna relay with 12V power outputs.

Upload

Band decoder settup is performed via firmware source code. It is compile and upload to device with Arduino GUI.

• For beginners Getting Started with Arduino.
• Connect mini USB connector on left side enclosure.
• Download source code and open in GUI.
• Select menu
• Tools/Board/Arduino nano
• Tools/Procesor/ATmega328
• Tools/Port/<your port>
• If enable Ethernet
• Download ethernet2 library https://github.com/adafruit/Ethernet2
• Find and open file Dhcp.h and replace line

  from
    int beginWithDHCP(uint8_t *, unsigned long timeout = 60000, unsigned long responseTimeout = 5000);  
  to
    int beginWithDHCP(uint8_t *, unsigned long timeout = 6000, unsigned long responseTimeout = 5000);

Configure

• Description antennas - show on LCD and web page, firt and last line do not change

  char* ant[] = {
    "All OUT off",  // <-- do not change this line
    "160m Vert.",
    " 80m Dipole",
    " 40m Moxon",
    " 30m Dipole",
    " 20m 2x 5el",
    " 10m 4x 6el",
    "M-off->BCD",  // <-- do not change this line
  };

• Inputs level - changing inputs level also need set JP8 jumper. Before opening enclosure has to be removed eight screws (three on left side, three on right side, two on rear side).
• Set JP8 to HIGH - activate BCD inputs with TTL signal level (1k ohm pull-down resistor). And uncoment line

  #define inputHigh          // enable input High level (default)

• Set JP8 to LOW - activate BCD inputs to ground (1k ohm pull up resistor). And coment line

  //#define inputHigh          // enable input High level (default)

• Number of inputs

  #define Inputs      6      // number of antenna used

• Number of ports

  #define Ports       2      // number of - IN/OUT pair devices and LCD lines (support from 2 to 4)

• LCD culumn

  #define LCDculumn  16

• Serial Echo, show status on serial interface

  //#define serialECHO       // enable TX echo on serial port
  #define SERBAUD    9600    // [baud] Serial port baudrate

• Ethernet - before enable in firmware need open enclosure and instal optional module USR-ES1.

  //#define EthModule          // enable Ethernet module

• Ethernet addres may be get automatically from DHCP server - for enable uncoment line

  #define __USE_DHCP__                    // Uncoment to Enable DHCP

• Static IP address (if DHCP disable) set in this lines

  IPAddress ip(192, 168, 1, 220);         // IP
  IPAddress gateway(192, 168, 1, 200);    // GATE
  IPAddress subnet(255, 255, 255, 0);     // MASK
  IPAddress myDns(8, 8, 8, 8);            // DNS (google pub)
  EthernetServer server(80);              // web server PORT
