Milan Technology RS485-CF-0x - Manual

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.

RS485-CF-0X in the NETWORK
The RS485-CF-0x can be used to install a fiber network extension between
RS-485 or RS-422 network nodes.
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).
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).
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.).
The dip switch also allows site selection of 1K ohm pull down on
"transmit/receive - (B) RS485 2wire, transmit - RS422" or of 1K ohm pull up
on "transmit/receive + (A) RS485 2wire, transmit + RS422” (see page 3).
