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 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
w i r e , R S 4 2 2 a n d r e c e i v e + R S 4 8 5 4 w i r e , R S 4 2 2 " p a i r o r o n t h e
"transmit/receive - (B) RS485 2wire, transmit - RS422 and transmit/receive +
(A) RS485 2wire, transmit + RS422" pair (see page 3.).
