To fully comply with EMI (electro-magnetic interference) specifications, the use
of shielded or screened cables may be required. “Shielded” describes
IBM-defined cables used with the DB-9 connector. “Screened” describes
cables that are electrically similar to Category 4 UTP (Unshielded Twisted Pair),
but with an added shield or screen.

but with an added shield or screen.
10BaseT or 100BaseTx (Twisted Pair)
100BaseTx requires Category 5 (100-Ohm UTP) cabling.
The Ethernet standard does not allow a direct 10BaseT connection between a
single computer and a single printer. Use 10Base2 (Thin Ethernet) to connect a
single computer to a single printer.

Do not use “silver satin” telephone extension cables for 10BaseT networks,
either as drop cords or as patch cables in the wiring closet. (Silver satin cables
are flat, usually silver or gray, with 28-gauge stranded or tinsel conductors.) Do
not use shielded twisted pair cable intended for IBM Token Ring networks or
voice-grade (level 1 or 2) unshielded twisted pair cable for wiring runs. These
cables do not meet the requirements for 10BaseT and will lead to
unreliable operation.

10Base2 (Thin Ethernet)
Depending on the type of Ethernet cables you use and your network
configuration, you may need to use terminators at certain points in the
installation. Refer to the manufacturer’s documentation for your Ethernet
adapters and cables for details.

10Base5 (Thick Ethernet)
Connecting the printer using thick coax (10Base5) requires an adapter; contact
your dealer to obtain adapters, cables, and terminators.
