Slide-in-Module Media
Converter

RS485/422 Copper to Fiber

Transition Networks CRS4Fxxxx­10x series media converters are
designed to be installed in the
PointSystem™ chassis and connect
RS485/422 copper cable to fiber­optic cable at asynchronous data

rates up to 1.25 Mb/s.

The CRS4F31xx-10x media converters use a male DB-9 port for the copper link:

The CRS4F32xx-10x media converters use a 6-position terminal block for the copper

link:

* Maximum cable distance is 1200m (4000 ft)

@ <90 kb/s decreasing logarithmically to
92m (300 ft) @ 500 kb/s.

**Typical maximum cable distance. Actual

distance is dependent upon the physical
characteristics of the network installation.

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 flat­blade 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) RS485 4-wire, receive (-) RS422

• Receive (+) (A) RS485 4-wire, receive (+) RS422

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) RS485 2-wire, transmit (-) RS422

• Transmit/Receive (+) (A) RS485 2-wire, transmit (+) RS422

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) RS485 2-wire, transmit (+) RS422

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) RS485 2-wire, transmit (+) RS422

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) RS485 2-wire, transmit (-) RS422

• Transmit/Receive (+) (A) RS485 2-wire, transmit (+) RS422
for RS422 2-wire, half-duplex operation

Set switch 5 to 4-wire (down) to enable the wire pair:

• Receive (-) (B) RS485 4-wire, transmit (-) RS422

• Receive (+) (A) RS485 4-wire, transmit (+) RS422
for RS422 4-wire, full-duplex operation

Switch 6 - RS485 / RS422

up = RS485
down = RS422

Set switch 6 to RS485 (up) to prevent echo in the 2-wire mode.

Set switch 6 to RS422 (down) to allow “transmit only” for the wire pair:

• Transmit/Receive (-) (B) RS485 2-wire, transmit (-) RS422

• Transmit/Receive (+) (A) RS485 2-wire, transmit (+) RS422

warning could result in an eye injury or blindness.

WARNING: Use of controls, adjustments or the performance of procedures other than
those specified herein may result in hazardous radiation exposure.

CAUTION: Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB, RS232,
RS422, RS485, DS1, DS3, Video Coax, etc., are intended to be connected to intra­building (inside plant) link segments that are not subject to lightening transients or

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 media converter inserted properly into the chassis?

• Is the power cord properly installed in the chassis 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
RS485/422 copper link?
NO

• Check the RS485/422 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 for proper configuration and check the RS485/422

cables for proper connection.

• Contact Technical Support: US/Canada: 1-800-260-1312, International:

00-1-952-941-7600.

FCC Regulations

This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference, in which
case the user will be required to correct the interference at the user's own expense.

Canadian Regulations
