PC Connection
Using LAN Directly to PC
Attach one end of an RJ-45 Ethernet
crossed-over cable
to the touch panel CUEnet (LAN) port and attach
the other end of the RJ-45 Ethernet cable to your computer.
Ethernet Crossed-Over Cable
This cable can be used to cascade hubs, or for connecting two Ethernet stations back-to-back without a hub.
It works with 10Base-T, 100Base-TX, 100Base-T4 and 1000Base-T. Use a good enough cable, if you are
confused about categories of cables then use Category 5 (enhanced) and you'll be fine even at 1000Base-T.

That means that the White/Orange cable connected to NIC 1 pin 1 should go to NIC 2 pin 3 and NIC 1 pin 2
to NIC 2 pin 6 etc.
Notes
1. 1000Base-T names are in parentheses.
2. It's important that each pair is kept as a pair. TX+ & TX- must be in the pair and RX+ & RX- must
together in another pair. Just as the table above shows.
3. While 10Base-T and 100Base-TX only uses 2 pairs, please connect all four since 100Base-T4 and
1000Base-T needs them and save you some future debugging.
4. The colors originate from the numbering and name on NIC 1.
5. The connection is based on IEEE Standard 802.3, 2000 Edition.
