Installation
CAUTION: Wear a grounding device and observe electrostatic discharge precautions
when setting the switches. Failure to observe this caution could result in damage to,
and subsequent failure of, the media converter.
Set the 6-Position Switch
The 6-position switch is located on the side of the media converter. Use a small
flat-blade screwdriver or a similar device to set the recessed switches. Refer to
the drawing for the locations of the six individual switches.
Switch 1 - 130 ohm resistor on “receive”
up = Disable.
down = Enable. (Switch 5 must also be set to “4-wire” (down).)
When enabled, switch 1 inserts a 130 ohm resistor on the wire pair:
• Receive (-) (B) RS-485 4-wire, receive (-) RS-422
• Receive (+) (A) RS-485 4-wire, receive (+) RS-422

Switch 2 - 130 ohm resistor on “transmit”
up = Disable.
down = Enable. (Switch 5 must also be set to “2-wire” (up).)
When enabled, switch 2 inserts a 130 ohm resistor on the wire pair:
• Transmit/Receive (-) (B) RS-485 2-wire, transmit (-) RS-422 and
• Transmit/Receive (+) (A) RS-485 2-wire, transmit (+) RS-422.
Switch 3 - 1K ohm “pull-down”
up = Disable.
down = Enable. (Switch 5 must also be set to “2-wire” (up).)
When enabled, switch 3 enables a 1K ohm pull-down on the wire:
• Transmit/Receive (-) (B) RS-485 2-wire, transmit (+) RS-422.
Switch 4 - 1K ohm “pull-up”
up = Disable.
down = Enable. (Switch 5 must also be set to “2-wire” (up).)
When enabled, switch 4 enables a 1K ohm pull-up on the wire:
• Transmit/Receive (+) (A) RS-485 2-wire, transmit (+) RS-422.
Switch 5 - 2-wire / 4-wire
up = 2-wire.
down = 4-wire.
Set switch 5 to 2-wire (up) to enable the wire pair:
• Transmit/Receive (-) (B) RS-485 2-wire, transmit (-) RS-422 and
• Transmit/Receive (+) (A) RS-485 2-wire, transmit (+) RS-422.
for RS-422 2-wire, half-duplex operation.
Set switch 5 to 4-wire (down) to enable the wire pair:
• Receive (-) (B) RS-485 4-wire, transmit (-) RS-422 and
• Receive (+) (A) RS-485 4-wire, transmit (+) RS-422.
for RS-422 4-wire, full-duplex operation.
Switch 6 - RS-485 / RS-422
up = RS-485.
down = RS-422.
Set switch 6 to RS-485 (up) to prevent echo in the 2-wire mode.
Set switch 6 to RS-422 (down) to allow “transmit only” for the wire pair:
• Transmit/Receive (-) (B) RS-485 2-wire, transmit (-) RS-422 and
• Transmit/Receive (+) (A) RS-485 2-wire, transmit (+) RS-422.

Troubleshooting
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 PWR (Power) LED on the media converter illuminated?
NO
• Is the power adapter the proper type of voltage and cycle frequency for
the AC outlet? (See “Power Supply DC Output” on page 9.)
• 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: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 2.
2. Is the RXC LED illuminated when data is sent across the RS-
485/422 copper link?
NO
• Check the RS-485/422 copper cable for proper connection.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 3.
3. Is the RXF (fiber link) LED illuminated?
NO
• Disconnect and reconnect the fiber cables to restart the initialization
process.
• Verify that the TX and RX cables on the media converter are connected
to the RX and TX ports, respectively, on the other media converter.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
YES
• Proceed to step 4.
4. Does the data fail to move across the link, even though both RXC
and RXF LEDs are illuminated?
YES
• Check switches 5 and 6 (page 3) for proper configuration and check the
the RS-485/422 cables for proper connection.
• Contact Technical Support: US/Canada: 1-800-260-1312, International:
00-1-952-941-7600.
