It is vital that your Ethernet cables be the correct cables, and properly terminated
with the correct pinout.
Choosing a network cable
Ethernet links use Category (CAT) 3, 4, 5, 5e, or 6, unshielded twisted pair (UTP) or
shielded twisted pair (STP) cables, terminated with RJ-45 connectors. Ethernet
cables are limited to 328' (100 m).
Do not use standard telephone cables. Telephone cables do not support
Ethernet or Fast Ethernet.
Do not stretch or bend cables. Transmission errors can occur.
The cable used depends on your network speed. The ISS supports both 10 Mbps
(10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet), half-duplex and
full-duplex, Ethernet connections.
• 10Base-T Ethernet requires at a minimum CAT 3 UTP or STP cable.
• 100Base-T Fast Ethernet requires at a minimum CAT 5 UTP or STP cable.
Wiring the network cable
The cable can be terminated as either a patch cable or a crossover cable (figure 2-8)
and must be properly terminated for your application:
•Patch (straight through) cable — Connection of the ISS to an Ethernet hub,
router, or switcher that also hosts a controlling computer
•Crossover cable — Direct connection between the ISS and a controlling
computer
