CAUTION
-
Do not connect any of the outputs and power outputs to the analog or digital ground.
Neither connect outputs to each other. Doing either can result in a fault.
-
If analog and digital ground are shorted together, noise on the digital signals may affect the
analog signals. Accordingly, analog and digital ground should be separated.
-
Leave "Reserved" pins unconnected. Connecting these pins may cause a fault in the board.
Analog Input Signal Connection
Single-ended Input
The following figure shows an example of flat cable connection.
Connect separate signal and ground wires for each analog input
channel on CN1.
Single-ended Input Connection (Flat Cable)
The following figure shows an example of shield 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 each
analog input channel on CN1, connect the core wire to the signal line
and connect the shielding to ground.
Single-ended Input Connection (Shield Cable)
*1 The number of channels depends on each board. The AIO-160802LI-PE has eight channels.
CAUTION
-
If the signal source contains over 1MHz signals, the signal may effect the cross-talk noise
between channels.
-
If the board and the signal source receive noise or the distance between the board and the
signal source is too long, data may not be input properly.
-
An input analog signal should not exceed the maximum input voltage (relate to the board
analog ground). If it exceeds the maximum voltage, the board may be damaged.
-
Connect all the unused analog input channels to analog ground.
-
The signal connected to an input pin may fluctuate after switching of the multiplexer. If this
occurs, shorten the cable between the signal source and the analog input pin or insert a high-
speed amplifier as a buffer between the two to reduce the fluctuation.
-
Analog ground of CN1 is isolated from the ground in the PC.
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.
