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

Front cover

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