GPIB-140B is a 1KM, GPIB bus extender that can extend the cable length of a GPIB system up to one kilometer without compromising the integrity of the GPIB or requiring software modifications. The bus extender uses a buffered transfer technique to transfer data. The GPIB-140B also expands the maximum number of GPIB devices in a GPIB system up to 26. It supports unbuffered mode to transmit each data byte using the GPIB double-interlocked handshaking protocol. Alternatively, the bus extender supports buffered mode, which uses a first-in-first-out (FIFO) buffer technique to transfer data between the remote and local units at faster rates.
