USER’S GUIDE
The TRANSITION Networks Ethernet™ E-100BTX-SX-01 series 100BASE-TX to
100BASE-SX media converters connect 100BASE-TX unshielded twisted pair
cable to 850 nm 100BASE-SX multimode fiber-optic cable, using either an
ST connector (E-100BTX-SX-01) or an SC connector (E-100BTX-SX-01(SC)).
Maximum number
media converters in series:
2

Power Supply Requirements Replace power supply with only the equivalent
input rating (see below) and output rating (regulated 9VDC at 0.5 A).
A four-positiion switch on the media converter allows selection of Auto-
negotiation, half-duplex or full-duplex, and/or Link Pass Through (LPT)
/Remote Fault Detection (RFD). An MDI/MDI-X switch allows straight-
through twisted-pair cable to be used for crossover 100BASE-TX connections.

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.
