Installation NOTES

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

1. Connect host signal to AR-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-11 plug connectors at both cable ends.

NOTE: Install TRANSITION Networks balun part number: B-4554
between RJ-11 cable and coax connector.

• Install balun at host coax connector.

• Connect male RJ-11 plug connector at one end of twisted pair

cable to balun on host coax connector.

• Connect male RJ-11 plug connector at other end of cable to

female RJ-11 connector on AR-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 AR-CF-01 media converter near host to AR-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.
