Analog Output Signal Connection
This section shows how to connect the analog output signal by using a flat cable or a shield cable.
The following figure shows an example of flat cable connection.
Connect the signal source and ground to the CN1 analog output.
Figure 3.3. Analog Output Connection (Flat Cable)
The following figure shows an example of shield cable connection. Use shield cable if the distance
between the signal source and this product 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.
Figure 3.4. Analog Output Connection (Shielded Cable)
- If this product or the connected wire receives noise, or the distance between this product and the
target is long, data may not be outputted properly.
- For analog output signal, the current capacity is ±3mA (Max.). Check the specification of the
connected device before connecting this product.
- Do not short the analog output signal to analog ground, digital ground, and/or power line. Doing
so may damage this product.
- Do not connect an analog output signal to any other analog output, either on this product or on an
external device, as this may cause a fault on this product.
- Analog output signal outputs hundreds of
µ
voltages when USB cable is inserted.
