The
FR-232/ST is a low cost, compact, fiber converter designed to extend RS-232
transmissions up to 2Km without any repeaters. The transmissions run in
fiber which provide for excellent data security as well as being immune
to EMI/RFI, variations in ground potentials, and lightning strikes. The
FR-232/ST operates at the physical layer (OSI Layer 1) and is completely
transparent to the RS-232 transmissions and protocols. The FR-232/ST operates
off the RS-232’s interface power, requiring no external power adapter.
Utilizing an ST fiber cable, the FR-232/ST operates in Full Duplex mode
for bi-directional transmissions.

The
FR-232/ST RS-232 interface operates in DCE mode for direct connection to
DTE devices such as the PC COM Port. The handshaking lines RTS, CTS and
CD are all internally connected. DRS and DTR are also internally connected.
The FR-232/ST is completely interface powered and will operate at the full
115.2Kbps speed even with only RD, TD and SG connected (3-wire).
