PC104-AD16
Page 3
The analog channels can be reached externally at the D-Sub 37 female connector (P5, see Figure 1) on the
right side of the PC104-AD16. Two 20-way pin connectors P3, P4 allow the internal connection of current
shunts (ZU-CS250R optionally available).
The pin assignment in single-ended mode (PL10 and PL11 closed) is shown in the following figure and ta-
ble.

In differential mode (PL10 and PL11 connected), input 1 measures the voltage applied to pin 1 (A) and pin 9
(B) of the D-Sub 37 connector, for example. In reality, this operating mode is used for higher interference re-
sistance.
The pin assignment at the D-Sub 37 female P5 and the pin connectors P3, P4 is shown in the upper table and
following figure.
