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

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-10x 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-10x 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.
