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).

INSTALLATION
Set Switches
Use small flatblade screwdriver or similar device to set recessed switches
according to site installation.
1. Set the 2-wire /4-wire slide switch to the 4-wire setting to enable the
"receive – RS485 4 wire, RS422 and receive + RS485 4 wire, RS422"
pair for RS422 4 wire full duplex operation.
2. Set the RS-485/RS-422 slide switch to the RS-485 position to prevent
echo in two-wire mode. Set the RS-485/RS-422 slide switch to the RS-
422 to allow transmit only on "transmit/receive - (B) RS-485 2wire,
transmit - RS-422 and transmit/receive + (A) RS-485 2wire, transmit +
RS-422" pair.
3. Refer to drawing and to notes below for setting 4-position DIP switch.
* Position 1 ON inserts 130 ohm terminator on the "receive – RS485
4 wire, RS422 and receive + RS485 4 wire, RS422" pair.
** Position 2 ON inserts 130 ohm terminator on the "transmit/receive -
(B) RS485 2wire, transmit - RS422 and transmit/receive + (A) RS485
2wire, transmit + RS422" pair.
*** Position 3 ON enables 1K ohm pull
down on "transmit/receive - (B)
RS485 2wire, transmit - RS422".
**** Position 4 ON enables 1K ohm pull
up on "transmit/receive + (A)
RS485 2wire, transmit + RS422
Install Cable
COPPER /DB-9 CONNECTOR
NOTE: Shielded cables are required on the DB-9 for EMC compliance.
1. Locate or build TIA/EIA-574-DB-9 compliant cables configured as
shown on page 6, with a male DB-9 connector at one end of
cable and with a straight-through cable.
2. Connect the male DB-9 connector at one end of cable to the
Media Converter female DB-9 connector.
3. Connect the other end of cable to the node device.

COPPER /TERMINAL BLOCK CONNECTOR
1. Locate or build TIA/EIA-574-compliant terminal block cables
configured as shown on page 6 and with straight-through cable.
2. Using a small flatblade screwdriver or a similar device, release each
terminal block installation location as necessary. Refer to the
diagram on page 6, connect the wires at one end of cable to the
Media Converter terminal block connector.
3. Connect the other end of the cable to the node device.
FIBER
1. Locate or build TIA/EIA-574-compliant fiber cable with male two-
stranded TX to RX connectors at both ends.
2. Connect the male TX and RX cable connectors at one end of the
cable to the TX and RX female connectors, respectively, on the
Media Converter.
3. Connect the male TX and RX cable connectors at the other end of
the cable to the RX and TX connectors of the IEEE 802.3™
compliant fiber device.
Connect to Power
1. Install the power adapter cord at the back of the Media Converter.
2. Connect the power adapter plug to AC power.
3. Verify that the Media Converter is powered by observing the
illuminated LED(s).
OPERATION
After installation, the Media Converter should function without operator
intervention.
Status LEDs:
Use the status LEDs to monitor Media Converter operation in the network.
RXF Flashing LED indicates data reception on the fiber link.
RXC Flashing LED indicates data reception on the copper link.
P(o)W(e)R Steady LED indicates connection to external power.

FAULT ISOLATION and CORRECTION
If the Media Converter fails, isolate and correct the failure by determining the
answers to the following questions and then taking the indicated action:
1. Is the P(o)w(e)r LED on the Media Converter illuminated?
NO
• Is the power adapter the proper voltage and cycle frequency for the
AC outlet?
NOTE: Refer to the “Power Supply Requirements” on page 7.
• Is the power adapter properly installed in the Media Converter and in
the grounded AC outlet?
• Does the grounded AC outlet provide power?
• Contact Technical Support at [phone].
YES
• Proceed to step 2.
2. Is the RXF LED illuminated?
NO
• Disconnect and reconnect the fiber cable to restart the initialization
process.
• Contact Technical Support: [phone].
YES
• Proceed to step 3.
3. Is the RXC LED illuminated?
NO
• Disconnect and reconnect the copper cable to restart the
initialization process.
• Restart the terminal device(s) to restart the initialization process.
• Contact Technical Support: [phone].
YES
• Proceed to step 4.
4. Does the data fail to move across the link, even though both
LEDs are illuminated?
YES
• Check the RS-485/RS-422 cables for proper configuration and
connection.
• Contact Technical Support at [phone].
