3.3 Input Signal Wiring
The device can receive external input signal via I/O interface, and here we take LineIn 0 as an
example to introduce input signal wiring.
Note
Input signal wiring may differ with different types of external devices.

NPN Device
If the VCC of NPN device is 12 VDC or 24 VDC and pull-up resistor is not used, its wiring is as
follows.

If the VCC of NPN device is 12 VDC or 24 VDC and 1 KΩ pull-up resistor is used, its wiring is as
follows.
