Overview

ISO/IEC TR 10192-2:2000 - "Information technology - Home Electronic System (HES) interfaces - Part 2: Simple Interface Type 1" specifies the mechanical, electrical, functional and test characteristics of a Simple Interface (SI) Type 1 used to connect simple two‑state devices (actuators/sensors) to a home network. Published as a type‑2 Technical Report, it defines the SI reference point between an SI device and an SI Network Access Unit (NAU), including pin assignments, signal forms, isolation and test procedures.

Key topics and technical requirements

• Signal definitions and pinout
  • Two signals: Control (C) and Monitor (M).
  • Pin assignments: C1 = pin 4, C2 = pin 3, M1 = pin 2, M2 = pin 1.
• Signal behavior
  • Control toggles device on/off; monitor reports actual state.
  • Monitor may be static (high for on, low for off) or dynamic (pulsed while on).
  • Timing examples: control/monitor pulse durations of 200–300 ms, response time ≤ 350 ms; dynamic monitor period ≤ 20 ms with minimum pulse ≥ 1 ms and duty ≥ 0.15.
• Electrical characteristics
  • Defined detect and operating currents and voltages for device and NAU sides (e.g., detect current thresholds
