Chapter 3 Signal Connections
Maintaining signal connections is one of the most important factors in
ensuring that your application system is sending and receiving data cor-
rectly. A good signal connection can avoid unnecessary and costly dam-
age to your PC and other hardware devices. This chapter provides useful
information about how to connect input and output signals to the PCI-
1752U/PCI-1752USO via the I/O connector.
3.1 I/O Connector Pin Assignment
The I/O connector on the PCI-1752U/PCI-1752USO is a 100-pin connec-
tor that enable you to connect to accessories with the PCL-10250 shielded
cable.
Figure 3-1 shows the pin assignments for the 100-pin I/O connector on
the PCI-1752U/PCI-1752USO, and Table 3-1 shows its I/O connector
signal description.
Note: The PCL-10250 shielded cable is especially designed for the
PCI-1752U/ USO to reduce noise in the analog signal lines. Please
refer to Section 1.3 Accessories.
3.2 Location of Jumpers and DIP switch
Figure 3-1 shows the names and locations of jumpers and DIP switch on
the PCI-1752U and PCI-1752USO.
There are two jumpers, JP1 and JP2 on the PCI-1752U/PCI-1752USO.
