Cabling and RJ-45 connector wiring
It is vital that your Ethernet cables be the correct cables, and that they be 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 will 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 ISM 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) cable — Connection of the ISM to an Ethernet hub, router, or
switcher that also hosts a controlling computer
• Crossover cable — Direct connection between the ISM and a controlling
computer
