IOtech's Extender488/F provides an economical solution to the 60 ft. (20 m) distance limitation of the IEEE bus. Using high-speed 115.2k baud serial data transmission, a pair of extenders can stretch the bus up to 4,000 ft. (1,000 meters).
Extender488/F uses differential RS-422 drivers and receivers that provide high-noise immunity with low-cost twisted-pair cabling. Extender488/F uses duplex fiber-optic data transmission, which provides high-electrical isolation as well as high noise immunity.
The Extender488/F operates transparently to the IEEE controller, requiring no special programming, with the exception of Parallel Poll. Parallel Polls must be performed twice due to the speed specification of the IEEE bus.
