• If your system is a link in a network and connects to two additional
components:
a. Connect a ThinWire cable to one end of the T-connector.
b. Remove the terminator from the other end and connect a second
ThinWire cable to it.
Push in and turn the connectors clockwise until they lock in place.
5. Connect the ThinWire cable to one of the following devices.
• A ThinWire Ethernet Multiport Repeater (DEMPR), which can be
connected to a baseband Ethernet cable and which connects up to
eight ThinWire segments in a local area network
• A ThinWire Ethernet Singleport Repeater (DESPR), which can be
connected to a baseband Ethernet cable and which connects one
ThinWire segment
• A ThinWire Ethernet adapter in another system or workstation
NOTE:
Contact your network manager or Digital service representative if
you have questions about network configurations.
When the ThinWire cable is connected to a DEMPR or DESPR, the ground
is provided by the DEMPR or DESPR chassis. If you are using a single-
segment ThinWire Ethernet local area network (LAN) with no DEMPR or
DESPR, you may need to ground the ThinWire connector on the CPU cover
panel.
CAUTION:
Each ThinWire Ethernet segment must have only one grounding
point.
To ground a single-segment ThinWire network at the CPU cover panel:
1. Remove the steel nut, lock washer, and plastic washer from the
ThinWire Ethernet connector on the CPU cover panel as shown in
Figure 22.
