Appendix B Ethernet Cables and
Connectors
There will be several Ethernet cables used in installing the EUM3005:
• EUM3005 Cross-over Cable: The 3 foot cross-over Ethernet cable that is provided
with the EUM3005. It can be used to connect the EUM3005 directly to the end-user’s
PC. A cross-over cable has one end wired according to T568A and the other end
according to T568B. Both ends have RJ45 connectors.
• Straight-Through Cable: Straight-through Ethernet cables have both ends wired
according to T568A with RJ45 connectors. Straight-through cables can be used in a
number of locations:
• If the 10 foot cable with the EUM3005 is not long enough, a straight-through
Ethernet cable can be used to provide extended distances.
• If the EUM3005 is to be connected to a router or Ethernet Switch, then a
straight-through Ethernet cable is used.
• If a router or Ethernet switch are used, then they are connected to the end-
user’s PC by a straight-through Ethernet cable.
The Ethernet cable used for the EUM3005 must have at least the RX and TX pairs wired as
shown in Table 7 with NO power on the other wires.
