IEEE-488 GPIB / IEC 625 cable assembly
Cable assembly ( colour grey) to IEEE-488 GPIB /IEC 625 . Designed to facilitate rapid interconnection up up to 15 programmable instruments ( in star or daisy chain configuration ) or control equipments equipped with IEEE-488 GPIB IEC 625 ( also known as HPIB ) communication link capable of , talking ,listening , talking and listening and or controlling . Each end of the assembly consists of a back to back 24-way male and female connector (rack and panel type ) with captive locking screws . The cable contains 24 conductors of which 16 are used for signal lines and the balance used for logic ground returns and overall sheild . Lines DAV , NRFD , NDAC, IFC , SRQ and ATN lines are each twisted together with a ground wire to form twisted pairs as detailed in the connector contact assignment table show below .|
Available in 1m and 2m lengths.
Voltage rating 200V d.c. Current rating 5A per contact . Contact resitance <10M ohm . Contact material , gold over copper .
connector contact assignments
A contact assignment of the cable connector and the device connector is as shown below:
|contact||signal line||contact||signal line|
|1||DIO 1||13||DIO 5|
|2||DIO 2||14||DIO 6|
|3||DIO 3||15||DIO 7|
|4||DIO 41||16||DIO 8|
|Note : Gnd.(n) refers to the signal ground return of the referenced contact.|
