● Operates as a 1:2 or 1:3 bus switch, permitting a single controller to operate three IEEE 488 Bus systems and up to 39 devices. Expands the number of instruments beyond the IEEE 488 limits. ● Operates as a 2:1 or 3:1 multiplexer so up to three bus controllers can share a common IEEE 488 bus, instruments, or GPIB peripherals. Time-shares expensive equipment. ● Cascadeable for large system applications. Easy expansion to nine buses. ● High data-transfer rate and minimum signal delays. Does not degrade system performance. ● Each bus controller can poll the 4842's status to determine availability of shared instruments or peripherals. Find out what's happening on the remote bus. ● Reservation stack with automatic SRQ to next controller. Reserves your turn with the shared equipment. ● IEEE-488.2 compatible unit uses SCPI commands. Uses standardized commands for easy programming.
The Model 4842 GPIB Bus Switch is a GPIB controlled switch that enables several GPIB Controllers to share one or more GPIB device(s) or lets a single GPIB Controller operate multiple Bus systems. The 4842 is basically a GPIB controlled A-B-C switch for the GPIB bus. When used as a Bus Switch, the 4842 lets a GPIB controller connected to the common port select and control devices attached to the numbered ports. When used as a Multiplexer, the ICS GPIB Bus Switch 4842 lets Bus controllers connected to the numbered ports share the common bus and any devices attached to it.
