High-Density 68-Pin SCSI Connector and P-Cable Single-
Ended Cable Pinout
High-Density Connector
The following facts apply to the information in the High-Density SCSI connector table below:
• A hyphen before a signal name indicates that signal is active low.
• The connector pin refers to the conductor position when using 0.025 inch centerline flat
ribbon cable with a high-density connector (AMPLIMITE .050 Series connectors).
• Eight-bit devices connected to the P-Cable must leave the following signals open: -dB (8),
-dB (9), -dB (10), -dB (11), -dB(12), -dB (13), -dB (14), -dB 15), and -dB (P1).
CAUTION Lines labeled RESERVED should be connected to GROUND in the bus
terminator assemblies or in the end devices on the SCSI cable.
RESERVED lines should be open in the other SCSI devices, but can be
connected to GROUND.
All other signals should be connected as defined.
