connector and an RX (receive) and a TX
(transmit) ST connector to multimode
fiber-optic cable for fiber network
extension distances up to 2 kilometers.

TR-CF-01(SM)

Provides a Token Ring RJ-45 twisted-pair
connector and an RX (receive) and a TX
(transmit) ST connector to singlemode
fiber-optic cable for fiber network
extension distances up to 15 kilometers.

TOKEN RING CABLE SPECIFICATIONS

INSTALLATION NOTES

Twisted-pair Cable

• Category 5 twisted-pair cable is recommended; Category 3 and 4
are supported at reduced cable lengths.

Fiber Extension Cable

• Be certain that the fiber extension cable is correct for distances
required at the site installation.

Switches

• Switches on the side of the media converter are used to configure
each media converter according to its location in the Token Ring
network. SET THE SWITCHES ON THE MEDIA CONVERTER

BEFORE CONNECTING TO POWER.

Using the switch setting references on page 3 and pages 4-5:

• Be certain that the media converter mode is set correctly for the

site installation

• Be certain that the media converter active/passive state is set

correctly for the site installation

• Be certain that the media converter IEEE 802.5j compliance

/non-compliance state is set correctly for the site installation

• Be certain that the twisted-pair cable configuration is set

correctly (straight through/RO or crossover/RI) for the site
installation.

Power Connections

• Install the media converter with the power supply provided.
(Output 9 VDC regulated, 550 mA).

• Connect the power supply cable to the media converter BEFORE
connecting the power supply cable to the AC outlet.

• Do NOT connect more than two media converters in series.
