Mil specification A-A-55140 defines an IEEE-488 connector which uses a cable termination via IDC [Insulation Displacement Connector]. The GPIB side is secured by a locking Bail.
Main description of the General Purpose Interface Bus, Additional IEEE488 CIDs
General requirements for a polarized shell, receptacle, electrical digital interface bus connector. This connector can be used in applications that require conformance to the IEEE 488 interface standard [HPIB], and require termination of a 1.27 millimeters (.050 inch) flat cable. Connectors are intended for commercial or industrial applications and shall not be used in military systems needing stringent environmental and electrical requirements.
Technical Note; The GPIB interface has been active for thirty years so there are thousands of pieces of gear fielded. As long as the equipment continues to function GPIB will remain in the field. However there is a replacement in the LXI Bus, or LAN eXtensions for Instrumentation which uses the faster Ethernet Interface.
