Overview

Maintaining signal connections is one of the most important factors in ensuring that

your application system is sending and receiving data correctly. A good signal con-

nection can avoid unnecessary and costly damage to your PC and other hardware

devices. This chapter provides useful information about how to connect input and

output signals to the PCL-730 via the I/O connector.

3.2

The PCL-730 has four on-board 20-pin flat-cable connectors (insulation displace-

ment, mass termination) and a DB-37 connector accessible from the card bracket.

See the figure on page 7 for the location of each connector.

Pin assignments for each connector appear in the following sections.

*NOTE: When JP4 is set to B1, Pin 19 on CN1 and Pin 10 on CN6 will both be

assigned PCOM1. When JP4 is set to A1, both pins will be assigned E.GND. For

JP5, Pin 17 & 19 and Pin 18 & 20 on CN2 will combine together (be the same GND)

when JP5 is set to A1. But Pin 17 & 19 and Pin 18 & 20 on CN2 will be different GND

(EI.GND1 and EI.GND2 separately) when JP5 is set to B1.
