CRS2F31xx-100
Slide-in-Module Media Converter
RS-232 to Fiber
Transition Networks CRS2F31xx-100
series media converters are designed to
be installed in the PointSystem™ chassis
and connect copper RS-232 cable to
fiber-optic cable at asynchronous data
rates up to 115 kB/s.
The CRS2F31xx-100 is designed to be
installed in pairs where one is the local
media converter and the other is the
remote.
* Typical maximum cable distance. Actual distance is dependent upon the
physical characteristics of the network installation.
The stand alone version of the media converter is SRS2F31xx-100. For more
information, see the SRS2F31xx-100 user’s guide on-line at:

Installation
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the switches and jumper. Failure to observe this
caution could result in damage to, and subsequent failure of, the media
converter.
Set the DTE/DCE Switch
The DTE/DCE switch is located on the side of the media converter. How the
DTE/DCE switch is set depends on the type of device connected to the media
converter:
• DTE (Data Terminal Equipment).
• DCE (Data Communication Equipment).
... and the type of RS-232 cable:
• Straight-through configuration cable.
• Null-modem configuration cable.

Set the Loop-Back Switch
The loop-back switch is located on the front panel of the media converter and
is used to debug network faults. (See page 10 in the “Troubleshooting”
section.)
To set the switch, use a small flat-blade
screwdriver or a similar device.
Norm Set the switch to “Norm” for
normal operation.
Loop Set the switch to “Loop” to
enable both fiber and copper
loop-back.

Installation -- Continued
CAUTION: Wear a grounding device and observe electrostatic discharge
precautions when setting the hardware/software jumper and installing the media
converter. Failure to observe this caution could result in damage to, and
subsequent failure of, the media converter.
Set the Hardware/Software Jumper
• The jumper is located on the circuit board.
• Use small needle-nose pliers to set the jumper.
Hardware The media converter mode is determined by
the switch settings (see pages 2-3).
Software The media converter mode is determined by
the most-recently saved, on-board
microprocessor settings.
Installing the Slide-in-Module
To install the CRS2F31xx-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 clockwise to secure
the module to the chassis front.

Install the Copper Cable
NOTE: Shielded RS-232 cables are required for EMC compliance.
1. Locate or build RS-232 cables with a female connector for the media
converter end and the correct gender connector for the DTE/DCE device
at the other end. And with either straight-through or null-modem cable
configuration.
2. Connect the female RS-232 connector at one end of cable to the male
RS-232 port on the first CRS2F21-100 media converter.
3. Connect the RS-232 connector at the other end of the cable to the RS-232
port on the DTE/DCE device.
