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.
3.1 I/O Connector Pin Assignments
There are four I/O connectors on the PCI-1241/1242. J1 is internal on-
board 10-pin simple horn connector for remote I/O module PCLD-8241.
J2 is also for PCLD-8241 and provided by PCI-1241 only. J3 is also a
internal on-board 10-pin simple horn connector to provide encoder input
channel for manual pulse generator (MPG) device, and the final one is a
SCSI-II 68-pin connector that enables you to connect to accessories with
the PCL-10168 shielded cable. Figure 3-1 and Figure 3-2 show the pin
assignment of remote I/O channels. Figure 3-3 shows pin assignment of
