The
FR-422/ST is a low cost, compact, fiber converter designed to extend RS-422/RS-485
transmission up to 2Km without any repeaters. The transmissions run in
fibers which provide for excellent data security as well as being immune
to EMI/RFI, variations in ground potential, and lighting strikes. The FR-422/ST
operates at the physical layer (OSI Layer 1) and is completely transparent
to the RS-422 transmissions and protocols. The FR-422/ST, utilizing an
ST fiber cable, operates in Full Duplex mode for bi-directional transmissions.
