Terminating shielded cable
N
The transmitter and receiver pair works with unshielded
twisted pair (UTP) or shielded twisted pair (STP) cables;
but, to ensure FCC Class A and CE compliance, STP
cables are required.
The Tx/Rx includes four shielded RJ-45 connectors and a length
of self-adhesive shielded tape that you can use to make the STP
cables that connect the transmitter and receiver.
N
Extron supplies the connectors and the shielded tape.

Terminate the STP cable as follows:
1. Peel back the cable shielding (gure 2-21) from the
end of the cable the length of the RJ-45 connector body
(approximately 7/8" [2.2 cm]) and fold it back.
Peel back shield and
fold back.

2. Cut away and discard the clear cellophane inner wrapper
from the end of the cable back to the folded-over cable
shielding.
3. Peel the backing off the self-adhesive shielded aluminum
tape and wrap it around the folded-over cable shielding,
slightlyoverlapping the beginning of the tape (gure 2-22).

Slightly overlap.
Cut and save the excess tape
for other connectors.

4. Cut the unused portion of the shielded tape and retain for
shielding other RJ-45 connectors.
5. Feed each individual wire into the appropriate slot of the
RJ-45 connector and crimp the cable in the normal manner,
folding the tangs at the end of the connector over the
shielded tape (gure 2-23).
