Analog Output Signal Connection
This section shows how to connect the analog output signal by using a flat cable or a shielded cable.
The following figure shows an example of flat cable connection.
Connect the signal source and ground to the CN1 analog output.

The following figure shows an example of shielded cable connection. Use shielded cable if the
distance between the signal source and board is long or if you want to provide better protection from
noise. For the CN1 analog output, connect the core wire to the signal line and connect the shielding to
ground.

CAUTION
- If the board or the connected wire receives noise, or the distance between the board and the target is
long, data may not be outputted properly.
- For analog output signal, the current capacity is ±5mA (Max.). Check the specification of the
connected device before connecting the board.
- Do not short the analog output signal to analog ground, digital ground, and/or power line. Doing
so may damage the board.
- Do not connect an analog output signal to any other analog output, either on the board or on an
external device, as this may cause a fault on the board.
