Installation
Mount the DAQ card to a PC/104 slot by connecting the PC/104 system connector (P7/P8, see Figure 1). Use
the spacer bolts (M3 x 15mm) to fix the DAQ card tightly.

Connections and Pin Assignments
The following board view shows the connectors on the DAQ card as well as the solder bridges on the bottom
side of the card. 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 or internally via the two 20-way pin connectors (P3, P4). The digital
lines are led through to the 26-way pin connectors (P1, P2) on the left side of the board. 5V power supply is
provided at the PC/104 system connector (P7, P8). The following figure shows the connectors on the board.

Analog Channels
In single-ended mode, the voltage difference between analog in-
put and ground is measured. The PC104-AD16 features 16 analog
inputs in the
±
10V,
±
5V,
±
2V, and
±
1V range and two analog
outputs (
±
10V). The input range is programmed for each channel
separately.
Besides single-ended connection, the PC104-AD16 also supports
the differential operating mode. Up to 8 analog inputs can be con-
nected in this case. The operation mode is configured with solder
jumpers (PL35, PL10, PL11) on the bottom of the board (see fig-
ure 2).
•
Always recalibrate the input after changing the operating mode (see chapter 4)!
•
The max. potentials to ground must not exceed
±
10V. The same also applies to differential meas-
urement (i.e. the difference between A and B, between A and GND, between B and GND, as well as
between the individual analog input channels)!
•
Any channel overload may influence measurements of other channels and may lead to wrong values
