NATIONAL INSTRUMENTS GPIB-120A BUS EXPANDER / ISOLATOR The National Instruments GPIB-120A is a GPIB expander. The IEEE 488.1 standard prescribes a maximum of 15 electrical device interface loads in a GPIB system. An NI GPIB-120A increases the maximum number of GPIB system devices from 15 to 28. The GPIB-120A is also useful in test and measurement systems because it provides an electrically isolated interface to one or more devices. The GPIB-120A is software transparent; you do not need to rewrite your application software. Expands the number of GPIB devices to 28 Bi-directional expansion - Controllers, Talkers, and Listeners can exist on either side of the expansion 400 Vrms electrical isolation between GPIB systems for 1 minute Software transparent - no software modifications required Signal buffering extends the maximum GPIB cable limit to 40 m (device load every 2 m of bus cable) Built-in 120 or 240 VAC power supply Meets FCC Class A electromagnetic noise emission requirements THIS DEVICE HAS BEEN TESTED AND FOUND TO BE IN WORKING CONDITION BEFORE LEAVING NEGATIVE FEEDBACK PLEASE CONTACT ME FIRST TO SEE IF WE CANT RESOLVE YOUR ISSUE · Our business hours are Monday through Friday, 7:00AM to 5:00PM CST. · We will answer e-mails as quickly as possible, but if you send one after 4:30 on Friday afternoon, you may not get a response until Monday morning. · The items listed are described as accurately as possible. · If the item is advertised as non-working, this means that we were unable to get it to work properly. · If the item is advertised as "powers up", that means that it was powered up but no additional testing was done on the unit. · Any pictures are of the actual item unless otherwise indicated above.
