Pin definitions for various types of connectors

The document provides a complete pin allocation table for all models, divided into two categories of interfaces:

1. * * 37 pin D-Sub (PCI-7230/7233/7234/7234P)**

Define the digital input IDI, digital output IDO, external interrupt EICOM, external ground EOGND, external load supply VDD, and isolated ground IGND pins respectively; There are differences in the pin layout among the four PCI models, with pure input cards having no DO pin, pure output cards having no DI interrupt pin, and 7234P replacing the VDD power supply pin position.

2. * * 50 pin SCSI-II (LPCI-7230/LPCIe-7230/cPCI-7230)**

The DI signal is divided into high and low differential H/L pin groups, with a unified arrangement of 16 DI+16 DO, multiple EICOM interrupts, EOGND isolation ground, and VDD power supply; The cPCI and LPCI series only have slight differences in the EICOM/EOGND ground pin.
