5.6 IEEE-488 INTERFACE CONNECTOR (WHEN MODEL 6224 OPTION IS PRESENT)
Connect to rear MPS IEEE-488 Interface connector with cables specified in the IEEE-488-1978 standard
document. The cable has 24 conductors with an outer shield. The connectors at each end are 24-way
Amphenol 57 Series (or equivalent) with piggyback receptacles to daisy-chain multiple devices. Secure
connectors in the receptacles by a pair of captive locking screws with metric threads.
The total length of cable allowed in a system is 2 meters for each device on the bus, or 20 meters total for a
maximum of 15 devices. The figure below and the table to the right shows the IEEE-488 Interface connector
pin location and signal names.
