IEEE-488 Reference
5-3
Custom cables may be constructed by using the information
in Table 5-1 and Figure 5-4. Table 5-1 lists the contact as-
signments for the bus, and Figure 5-4 shows the contact con-
figuration.
CAUTION
IEEE-488 common is connected to digi-
tal common. Maximum voltage between
digital common and earth ground is 0V.
