GPIB
When the optional GPIB interface unit has been fitted, connections are made to it using a 24-way
IEEE 488 male connector. If a stackable connector is used in order to interconnect more than two
pieces of equipment, ensure that no physical damage to the Service Monitor connector will result.
The pin connections are listed below and the pin locations shown in Fig. 2-5 IEEE488 parallel
port connections (as seen facing panel).
