• Weight: 30g (approx.)

Wiring diagram:

• 1P---AC: 220V live wire (or neutral)
• 2P---AC: 220V neutral wire (or live)
• 3P---+5V: Transmission power supply +5V (210mA), can be disconnected during data reception to reduce consumption
• 4P---GND: Digital circuit ground
• 5P---+5V: Working power supply +5V 11mA
• 6P---RX: TTL data input, connects to TXD of SCM
• 7P---TX: TTL data output, connects to RXD of SCM
• 8P---MODE: Mode selection, connect to 5V for high level or disconnect, connect to ground for low level
• 9P---NC/RST: Reset pin (active low), for frequent mode changes. Leave unconnected if this function is not used.
