RS-485/422 Serial-Port Fiber Extension
Media Converters
RS485-CF-01, RS485-CF-02
USER’S GUIDE
The TRANSITION Networks RS485-CF-0x series serial-port fiber extension Media
Converters extend distances between RS-485 or RS-482 nodes for up to two (2)
kilometers over multimode fiber or up to twenty (20) kilometers over singlemode
fiber.
RS485-CF-0x series Media Converters allow RS-485 two-wire half-duplex
operation, RS-485 four-wire full-duplex operation, and RS-422 four-wire
operation, with switch-selectable termination and biasing resistors, at speeds from
1 Kb/s to 500 Kb/s.

One slide switch on the RS485-CF-0x series Media Converter allows site
selection of RS-485 2-wire (half-duplex) operation, RS-485 4-wire (full-
duplex) operation, or RS-422 4-wire (full-duplex) operation (see page 3).
Provides one (1) terminal block RS-
485/RS-422 copper connector and
one (1) set of RX (receive) and TX
(transmit) SC 100BASE-FX connectors
to multimode fiber @ 850 nM.
RS485-CF-02(SC)
A second slide switch on the RS485-CF-0x series Media Converter allows
echo prevention in two-wire mode or transmission only on "transmit/receive -
(B) RS-485 2wire, transmit - RS-422 and transmit/receive + (A) RS-485 2wire,
transmit + RS-422" pair (see page 3).
Provides one (1) DB-9 RS-485/RS-422
copper connector and one (1) set of
RX (receive) and TX (transmit) SC
100BASE-FX connectors to multimode
fiber @ 850 nM.
RS485-CF-02
Provides one (1) DB-9 RS-485/RS-422
copper connector and one (1) set of
RX (receive) and TX (transmit) ST
100BASE-FX connectors to multimode
fiber @ 850 nM.
A 4-position dip switch on the RS485-CF-0x series Media Converter allows
site selection of 130 ohm terminator insertion on the "receive – RS485 4
wire, RS422 and receive + RS485 4 wire, RS422" pair or on the
"transmit/receive - (B) RS485 2wire, transmit - RS422 and transmit/receive +
(A) RS485 2wire, transmit + RS422" pair (see page 3.).
