Copper Cable and Connector
Category 3 or better twisted-pair copper wire is required. Either shielded twisted-pair (STP) or
unshielded twisted-pair (UTP) can be used. DO NOT USE FLAT OR SILVER SATIN WIRE.
CATEGORY 3:
Gauge
24 to 22 AWG
Attenuation
£
11.5 dB/100m @ 5-10 MHz
Maximum Number of Nodes
2 nodes
Maximum Cable Distance
100 meters (200 meters with better cable
RJ-45 Pin-outs
Pin 1=TD+, Pin 2=TD-,
Pin 3=RTD+, Pin 4=RD-
Twisted pair connection requires two active
pairs configured as straight through. The two
active pairs in an Ethernet™ 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
pairs.
INSTALLATION
Set MDI/MDI-X Switch
NOTE: Straight-through/crossover 10BASE-T
requirements are satisfied using the MDI/MDI-X
switch with straight-through cable. See page 6 for
cable configurations.
Using small flatblade screwdriver or similar tool
and referring to label at front of media converter,
set MDI/MDI-X switch position for site installation.
10BASE-T cable connections between a hub and
the media converter require the MDI/MDI-X switch to be set to MDI.
10BASE-T cable connections between the media converter and a terminal,
transceiver or NIC require the switch to be set to MDI-X
Install Cable
NOTE: See page 6 for cable specifications.
COPPER
NOTE: KEEP TWISTED PAIR RUNS AS SHORT AS POSSIBLE.
•
Locate or build 10BASE-T-compliant cables with straight-through
or crossover configuration and with male RJ-45 plug connectors
at both ends.
•
Connect male RJ-45 plug connector at one end of cable to media
converter RJ-45 jack connector.
•
Connect male RJ-45 plug connector at other end of cable to
10BASE-T terminal device RJ-45 jack connector (using straight-
through cable configuration) or to 10BASE-T hub RJ-45 jack
connector (using crossover cable configuration).
FIBER
•
Locate or build 10BASE-FL-compliant fiber cable with male two-
stranded TX to RX connectors at both ends.
•
Connect male TX and RX cable connectors at one end of cable to
TX and RX female connectors, respectively, on media converter.
•
Connect male TX and RX cable connectors at other end of cable
to RX and TX connectors of 802.3 compliant fiber device.
Connect to Power
•
Install power adapter cord at back of media converter.
•
Connect power adapter plug to AC power.
•
Verify that media converter is powered by observing illuminated
LED(s).
