Slide-in-Module Media Converter
RS-485/422 Copper to Fiber
Transition Networks CRS4Fxxxx-100
series media converters are designed
to be installed in the PointSystem™
chassis and connect RS-485/422
copper cable to fiber-optic cable at
asynchronous data rates upto1.25
Mb/s
The CRS4F31xx-100 media converters use a male DB-9 port for the copper link:
The CRS4F32xx-100 media converters use a 6-position terminal block for the
copper link:
* Maximum cable distance is 1200m
(4000’) @ <90 kb/s decreasing
logarithmically to 92m (300’) @ 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 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 and
• 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.

Install the Slide-In-Module
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when installing the media converter. Failure to observe this caution
could result in damage to, and subsequent failure of, the media converter.
To install the CRS4Fxxxx-100 media converter slide-in-module:
1. Locate an empty installation slot on the PointSystem™ Chassis.
2. Carefully slide the slide-in-module into the installation slot, aligning the
module with the installation guides.
3. Ensure that the module is firmly seated inside the chassis.
4. Push in and rotate the attached panel fastener screw to secure the module
to the chassis front.
Install the Fiber Cable
1. Locate or build fiber cable with male, two-stranded TX to RX connectors
installed at both ends.
2. Connect the fiber cables to the CRS4Fxxxx-100 media converter as
described:
• Connect the male TX cable connector the female TX port.
• Connect the male RX cable connector to the female RX port.
3. Connect the fiber cables to the other device (another media converter,
hub, etc.) as described:
• Connect the male TX cable connector the female RX port.
• Connect the male RX cable connector to the female TX port.

a DB-9 copper port (CRS4F31xx-100 models).
NOTE: Shielded RS-485/422 cables are required for EMC
compliance.
1. Locate or build RS-485/422 cables with a female DB-9
connector on one end and a DB-9 connector that is
compatible with the other device on the other end of the
cable.
2. Connect the female DB-9 connector at one end of cable to the male DB9 port on the CRS4F31xx-100 media converter.
3. Connect the DB-9 connector at the other end of the cable to the DB-9
port on the other device.
Power the Media Converter
The media converter is powered through the PointSystem™ chassis.
Install the Copper Cable (6-position terminal block)
Install the copper cable as instructed if the media converter has
a 6-position terminal block (CRS4F32xx-100 models).
NOTE: Shielded RS-485/422 cables are required for EMC
compliance.
1. Locate or build RS-485/422 cables with the six individual
wires stripped at both ends.
2. Insert the individual wires at one end of cable into the six
terminal block ports on the CRS4F32xx-100 media converter.
3. Insert the individual wires at the other end of the cable into the six
