6.2 I/O Electrical Feature and Wiring of Other Devices
The other devices include type I to type IV devices, and type VI and type VII devices. With
different device types, their I/O electrical feature varies.
● Type II device: Its Line 0/1/2/3 are all bi-directional signals.
● Type I, type III, type IV and type VI devices: Their Line 2 is non-isolated input signal, Line
3 is non-isolated output signal, and Line 0/1 are both bi-directional signals.
● Type VII device: Its LineIn 1 is non-isolated input signal, LineOut 3 is non-isolated output
signal, and Line 2 is bi-directional signal.
