Transition Networks NANOMETER E-100BTX-SX-01 Manuale utente
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)).
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.

CAUTION: RJ connectors are NOT INTENDED FOR CONNECTION TO THE
PUBLIC TELEPHONE NETWORK. Failure to observe this caution could result in
damage to the public telephone network.

Switch Settings and Cable Requirements
The two active pairs in a
100BASE-TX network are pins
1 & 2 and pins 3 & 6. Use only
dedicated wire pairs (such as
blue/white & white/blue,
orange/white & white/orange)
for the active pins.

Straight-through/crossover 100BASE-TX requirements are satisfied
using the MDI/MDI-Xswitch with straight-through cable.
Set the MDI/MDI-X switch to MDI for cable connections
between hub and media converter.
Set the MDI/MDI-X switch to MDI-X for cable connections
between media converter and terminal, transceiver or NIC.
Setting Switches
Use small flatblade
screwdriver or similar
device to set recessed
switches. Refer to label on
top of media converter for
MDI/ MDI-X switch
settings. Refer to drawing
at left for four-position
switch settings.
4-Position Switch (4th switch not used)
Auto-negotiation (UP) Detects and adapts to line
speed/operation mode of attached device.
Full/Half-duplex (UP) Allows an attached full-
duplex station to transmit and receive
simultaneously. (DOWN) Allows an attached
station to transmit and receive sequentially.
LPT/RFD (UP) Blinks the SDF or SDC LED if a
malfunction is detected at the unit to which the
media converter is attached.
MDI/MDI-X Straight-Through/Crossover
