compliant devices, extends the signal distance of a 317x or 327x Cluster

Controller

to terminal links.

B-CF-01 series media converters allow twisted-pair copper network extension
distances up to 1524 meters (762 meters each connection on two media
converters) OR coax copper network extension distances up to 614 meters
(307 meters each connection on two media converters) AND fiber network
extension distances up to 2 kilometers on multimode fiber and up to 8
kilometers on singlemode fiber.*

Installation NOTES

To install the B-CF-01 series media converter:

1. Connect host signal to B-CF-01 media converter.
NOTE: Set the configuration switch (located on the side of the

media converter) according to site requirements, using the
following:

Switch 1 NOT USED
Switch 2 UP = Twisted Pair

DOWN = Coax

Twisted-pair:

• Locate or build twisted-pair cables (See specifications, page 7)

with male RJ-45 plug connectors at both cable ends.

NOTE: Install TRANSITION Networks balun part number: B-4554
between RJ-45 cable and coax connector.

• Install balun at host coax connector.

• Connect male RJ-45 plug connector at one end of twisted pair

cable to balun on host coax connector.

• Connect male RJ-45 plug connector at other end of cable to

female RJ-45 connector on B-CF-01 media converter.

Coax:

• Locate or build coaxial RG-62 cables (See specifications, page

7) with male BNC connectors at both ends.

• Install one end of cable to female BNC connector on host.

• Install other end of cable to female BNC connector on media

converter.

2. Connect B-CF-01 media converter near host to B-CF-01 media
converter near terminal device.

• Locate or build fiber cable that conforms to cable

specifications (See page 7) with male fiber connectors at both
ends.

• Connect one end of first fiber cable to B-CF-01 media converter

TX connector.
