The correct serial cable you need depends upon which GPIB model you are
using. If you are using the GPIB-232CT-A, you must use a null-modem
serial cable (also known as an RS-232 DTE-to-DTE cable) to connect your
computer to the GPIB-232CT-A. If you are using the GPIB-485CT-A, you
must use a twisted pairs null-modem serial cable (also known as an RS-485
null modem cable) to connect your computer to the GPIB-485CT-A.
Table 2-3 lists the National Instruments cables that are null-modem serial
cables.
