ATTENTION
For Fiber Ring Users:
To avoid problems when setting up a fiber ring, each Serial/Fiber
Converter unit making up the ring must be powered down and set
to “Ring mode.” Next, make sure all cables are connected properly,
and then power up all devices connected to the ring.
NOTE
“Ring Mode” can only be used with half-duplex applications (i.e.,
RS-485 multi-drop communication).
DIP Switch Selectable Terminator
The Serial/Fiber Converter’s termination resistor is set with a DIP switch located
on the outside of the converter’s casing.
No Configuration Required for Baudrate Settings
The Serial/Fiber Converter is compatible with any baudrate from 50 bps to 921.6
Kbps. The Serial/Fiber Converter automatically converts the signal back and forth
between serial (RS-232, RS-422, or RS-485) and fiber, and does not need to
interpret the signal or the baudrate of the transmitting device.
Features
• “Ring” or “Point to Point” transmission
• Extend RS-232/422/485 transmission distance up to 5km
• Compact size
• Decrease signal interference
• Protect against electronic degradation and chemical corrosion
• Supports baudrates up to 921.6 Kbps
• Extended operating temperature from -40 to 75°C
Package Checklist
Before installing the Serial/Fiber Converter, verify that the package contains the
following items:
• 1 IE-MCT-1RS232/485-1SC/ST media converter
• Power jack to 3-pin terminal block adaptor
• Stick-on pads
• Hardware installation guide (printed)
If any of these items are missing or damaged, please contact your Weidmüller

Dimensions and Appearance
Weidmüller Serial/Fiber Converters are easy to set up and use. The serial
terminal block of one of the converters connects to your computer, the serial
terminal block of the other converter connects to your serial device, and the two
converters are connected by fiber cable.
NOTE
Electrostatic Discharge Warning!
To protect the product from damage due to electrostatic discharge,
we recommend wearing a grounding device when handling your
Serial/Fiber Converter.
