IP Switch with ESP32-GATEWAY

This revision is from 2017/12/10 14:21. You can Restore it.

This kit worked with ESP32-GATEWAY Ethernet/WiFi module from OLIMEX. Below step by step assembled manual for 16 outputs (two boards).

Hardware

DC power jack

  • ⚠ 5 volt DC only - higher voltage damage both electronics!
  • Size 2,1/5,5mm diameter to connect input power 5V DC (center positive)
  • Consumption below 500mA

Output header

pin-2 out CAT TXD / CI-V
pin-3 out USB4 +5V output

How to assembly

Top side PCB

❏ Solder 2x12 1k rezistors R1-R14

❏ 2x10 100n capacitors C19-C35

❏ 2x8 LED diodes D38-D45

❏ One BCD ID switch P6 on LEFT board

❏ One female pin header P5 on LEFT board

❏ One male pin header P4 on RIGHT board

❏ 2x 74HC595 IO U8

❏ 2x DIP socket for U5

❏ 2x male 2x3 pin header P2

❏ 2x male 2x7 pin header P3

Bottom side PCB

❏ One DC jack J1 on LEFT board

❏ One male 1x20 pin header P1 on LEFT board

❏ Put output driver to DIP socket by your preferency

  • ULN chip for switching by output collector (grounding) need use two Jumpers on left P2 pin strip
  • UDN chip for switching by output emitter (voltage from P3 Vin) need use two Jumpers on right P2 pin strip

ESP32-GATEWAY board

❏ One femmale 1x20 pin header CON1 on TOP side OLIMEX ESP32-GATEWAY

Firmware

  1. Download and install last version Arduino IDE
  2. Download and install ESP32 support for arduino from GitHub - installation instruction included.
  3. Download IP switch firmware source from GitHub
  4. Edit source
    1. For use Ethernet wiring connection preset configuration
      #define ETHERNET               // Enable ESP32 ethernet (DHCP IPv4)
//#define WIFI                  // Enable ESP32 WIFI (DHCP IPv4)
    2. For use WiFi connection use this settings
      //#define ETHERNET               // Enable ESP32 ethernet (DHCP IPv4)
#define WIFI                  // Enable ESP32 WIFI (DHCP IPv4)
      and set your SSID and password for access
      const char* ssid     = "YOUR-SSID";
const char* password = "YOUR-PASSWORD";
  5. Select menu Tools/Board:"OLIMEX ESP32-GATEWAY"
  6. Select menu Tools/Port/YOUR-CONNECTED-PORT
  7. Upload firmware

Setup

For controlled from Open Interface III keyboard

  • Upload firmware by previous steps
  • Select Network ID with P6 BCD switch. ID 0-7 represent keyboard switching for eight independent IP switch by selected band
  • Connect to same local network with DHCP as Open Interface III
  • After power up both devices, is automaticaly pair and work

For controlled from Open Interface III rotary encoder

  • Upload firmware by previous steps
  • Select Network ID with P6 BCD switch. ID 8-F represent keyboard switching for eight independent IP switch by selected band
  • Connect to same local network with DHCP as Open Interface III
  • After power up both devices, is automaticaly pair and work

For controlled from Open Interface III band decoder
