5. Setup
5.1. 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.

- (BI_DD-) 8 Brown 5 - (BI_DC-)
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.
