GPIB Connector [Receptacle to Plug Assembly]
This page describes the GPIB connector including a drawing with dimensions.
Pins 1 to 12 are located on the bottom row, while pins 13 to 24 are located on the top row as shown
[narrow side of connector].
The top portion of the drawing depicts a female connector,
and the bottom drawing depicts a male GPIB connector.
The Female connector provides pin 1 on the bottom left pin, pin 12 on the bottom
right, pin 13 is above pin 1, while pin 24.
The male connector has the same pin out but it's mirrored. So the male connector has pin 1 on the
lower right.
A pin out table with signal names for the GPIB connector is
provided after the connector drawing.
The Mechanical [Physical] Dimensions for the GPIB connector is
shown in the graphic above.
In addition to the physical dimensions, the drawing also shows the type of bolts.
The GPIB bus is also called, HPIB bus, or IEEE-488 bus.
IEEE-488 Connector types: (The connector pin-outs differ):
... IEEE488/ANSI MC1.1; 24 pins, accepts a ribbon cable.
... IEC 625-1, MIL-C-24308; 25 pins
Connectors are tested to MIL-STD-202E (Environmental).
Maximum cable length is 20 meters, or 2 meters per device - which ever is
less. Devices may be connected in either a Star or Linear fashion.
Metric threads are Black, English threads are Silver;
the two will not mate together
