Door Controller/Construction details

Construction details

• Serial version: TX-TX, RX-RX from RS232 driver to Arduino
• Ethernet version: TX-RX, RX-TX from Ethernet driver to Arduino
• Suggested wiring order (refer to Door_Controller/Pinouts#Arduino_Pinout)
  • 1 F-F 5V PSU -> Ethernet (Vdd)
  • 5 M-F vIn/GND/Reader(D0,D1)/Voltage_Sense -> Arduino
  • 3 M-F Arduino TX/RX, GND-> Ethernet
    • TX(Ethernet)-> RX(Arduino)
    • RX(Ethernet)-> TX(Arduino)
  • 1 M-F Arduino CFG -> Ethernet
  • 4 F-F Relay -> Arduino

Connection board

Currently constructed from RS 433-832 stripboard, cut to 15x5 sections (was 12x5 before moving lock connector to board)

• Brown/Blue cable length: cut to 75mm
• Voltage sense resistors: 4k7 connected to GND, 15k connected to Vin. Common joined and connected to Arduino A3
• Reverse voltage / flyback protection diode: 1N4004, with stripe connected to V+(lock) and other end connected to GND

Bi-colour LED

• Black/Red/Green cable length: cut to 30cm
• For LED SC07647
  • Resistor value 120R
  • Pin by flat edge: Red
  • Centre pin: Ground
  • Pin opposite flat edge: Green

Ethernet configuration

Don't forget to also connect to the board and set the MAC address stored in EEPROM to match the address of the network card, as well as the serial number:

set mac 00-FA-0F-AB-12-34

set serial 123

Front cover

• 2mm hole for LED using drilling template (Approx 18mm in from each edge)
• File down head of LED for maximum diffusion
