Making Your Own Cables
If you choose to make your own cable, see Figure Figure 2-3 and
Figure Figure 2-4.
Figure Figure 2-3 illustrates how to make a DE-9S-to-DE-9P, DTE-
to-DCE interface cable that can replace the cable and adapter
combination of the HP 24542U cable and the HP 5181-6639 adapter for
use with PORT 2 of the 59551A.

to PORT 2
Figure Figure 2-4 illustrates how to make a DE-9S-to-DB-25P,
DTE-to-DTE interface cable that can replace the HP 24542G cable
(25-pin male to 9-pin female connectors) for use with PORT 1.
