Instrument And Host Computer Interconnection; Host Computer/Instrument Direct Connection - Fluke 2680A User Manual

Instrument and Host Computer Interconnection

You may interconnect 2680 Series instruments and host computer(s) with
10/100BaseT (twisted pair) wiring. If your site is already wired, you will probably
use the wire in place. If your site is not wired, you are connecting your instrument
directly to your host computer.

Host Computer/Instrument Direct Connection

You can connect a single instrument directly to a host computer using
10/100BaseT cable, but you must use a special cable that has its transmit and
receive lines crossed. The crossed lines allow each end to transmit to the receive
terminal at the other end. For more information, see Ethernet Cabling in
Appendix G.
