Typical maximum cable distance. Actual distance is dependent upon the
physical characteristics of the network. (TX) = transmit (RX) = receive
** CBFTF1029-
120
and CBFTF1029-
121
are intended to be installed in the same
network where one is the local converter and the other is the remote.
*** CBFTF1029-

Set the Dip Switches
The dip switches are located on the side of the media converter. Use a small,
flat-blade screwdriver or a similar device to set each dip switch.
“SW1” switches 1 - 6
Dip switches 1, 2, and 3 apply only to twisted-pair copper port 1 (TP1).
Dip switch 4 applies to fiber port 1 (F1).
Dip switch 5 applies to all twisted-pair copper ports (TP1, TP2, TP3, TP4, TP5).
Dip switch 6 is not in use.
“Config. Switches” 1 - 4
Dip switches 1, 2, 3, and 4 apply
only
to twisted-pair copper port 2 (TP2).
NOTE:
Switches 1, 2, and 3 apply
only
to twisted-pair
copper port 1 (TP1)
.

1. Twisted-Pair Auto-Negotiation
UP (Enabled)
- The media converter “advertises”
ALL rate and mode capabilities to the network:
• 100Mb/s full-duplex • 100Mb/s half-duplex,
• 10Mb/s full-duplex • 10Mb/s half-duplex.
DOWN (Disabled)
- The bridging media
converter does not “advertise” the rate and mode
capabilities to the network.
Switches 2
and
3
are
then used to set the twisted-pair rate and mode.
2. Twisted-Pair Rate
UP (100Base-TX)
- Sets the twisted-pair rate to
100Base-TX.
DOWN (10Base-T)
- Sets the twisted-pair rate to
10Base-T.
3. Twisted-Pair Mode
UP (Full-Duplex)
- The twisted-pair cable
distances are constrained by the cable
requirements (see pages 1 and 2).
DOWN (Half-Duplex):
- The twisted-pair cable
distances are constrained by the 512-Bit Rule (see
page 9).
