Rear Panel Connectors
GPI I/O Connections
The three GPI connectors each support 24 bidirectional GPI contacts. Each individual GPI
can be configured via software as an Input or Output GPI. They are identified in the
software as:
• GPI A, line 1 to 24
• GPI B, line 1 to 24
• GPI C, line 1 to 24
The pinouts of all three connectors are identical, and are shown in the following table:
Signal polarity: N = Negative; P = Positive
GPI Circuits
The individual GPI contacts can be configured as either inputs or outputs. See KXA-GPI-
GEN , on page 209 for input / output electrical requirements and specifications. For
interfacing purposes, the card’s internal input and output equivalent circuits are as shown
in the following diagrams:
Connector label Connector type Function
GPI A 1-24 DB-50 (female) GPI A input/output (bidirectional) connections
GPI B 1-24 DB-50 (female) GPI B input/output (bidirectional) connections
GPI C 1-24 DB-50 (female) GPI C input/output (bidirectional) connections
