2.4 Connecting the System to the Network
1. Connect the network cable to a twisted-pair-to-transceiver interface box.
2. Connect the interface box with an appropriate cable to a network
transceiver.
Figure 2-5 shows a typical arrangement for connecting the system to an
Ethernet network.
3. For Ethernet cables, determine if the cable has N-type screw-on
connectors at the ends.
• If the Ethernet cable lacks N-type connectors at the ends, use a “vampire”
tap to connect the cable to the transceiver. See Figure 2-5. 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:
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.
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 the end of the coaxial cable. Use a female
double N-type connector.
Figure 2-5 shows the elements used in the installation process.
