Connecting to an External Device

DAI12-4(FIT)GY

11

Connecting an Analog Output Signal

Connecting a Voltage Output

Connecting with a Flat Cable

This example involves connecting the voltage output and the analog ground for each

channel to the input and the ground of an external device, using a flat cable.

Figure 3.3. Connecting a Voltage Output (Flat Cable)

Connecting with a coaxial cable

A coaxial cable can be used in situations where the module is at a relatively large

distance from the external device or when the noise immunity of the module must be

improved. In this case, the voltage output and the analog ground for each channel are

connected to the input and the ground, respectively, of the external device by using the

core wire and the shield braid of the coaxial cable.
