Signal Output
INET configuration
The specific number shown depends upon how INET cables are
connected among devices included in the loop. The value shown in the
example (8) implies the HP 5890 is the first instrument on the loop,
starting from the OUT receptacle on the controller device (the controller
is always defined as 0). A 9 indicates the HP 5890 is the second device
on the loop, etc, to a maximum value of 31.
If cabling is altered, or if one or more devices are powered off and then on
again, automatic loop configuration, initiated by the controller, updates
the displayed value accordingly.
Setting the default HP-IL address
Remaining displays in Figure 5•10show the process of defining a specific
HP•ILaddress for the HP 5890. Entry of any value from 8 through 31 is
permitted. An attempt to enter an invalid value results in the ADDRESS
LIMIT message shown.
