If the Ethernet cable lacks N-type connectors at the ends, use a “vampire”
tap to connect the cable to the transceiver. See Figure 2-8. To connect the
cable to the transceiver, use instructions provided with the vampire tap.

•
If the Ethernet cable has N-type connectors, connect the Ethernet cable to
the transceiver:
the transceiver:
a. Screw the Ethernet coaxial cable into one of the round screw-on type
connectors on the transceiver.
Use either one of the transceiver connectors.
Use either one of the transceiver connectors.
b. Screw the other Ethernet coaxial cable into the other round screw-on
type connector on the transceiver.
4. Determine if a terminator should be installed. Table 2-1 lists the cabling
limitations for Ethernet.
5. If termination is required, install a 50-ohm terminator in the unused
transceiver N connector or at the end of the coaxial cable. Use a female
double N-type connector.
