" STOP"keys on other devices on the INET loop (e.g., the controller) will
affect HP 5890A operation.
Once in " CONFIGURE NETWORK,"pressing
respectively, between " global"or " local"mode shows resulting displays as
in Figure 13-5.

Figure 13-5. INET "GLOBAL/LOCAL" Displays
An example of where having the HP 5890A in " local"mode might be
useful is in the case of conditioning a column: the HP 5890A may be
started or stopped as desired without affecting other devices on the INET
loop.
Note that " global"mode has two states: if GLOBAL flashes (default mode)
when displayed, the HP 5890A is in " global"mode, but NOT configured
into the INET system. When the HP 5890A is properly configured into the
INET system, GLOBAL is displayed continuously. This feature provides a
convenient diagnostic to determine if system configuration has occurred
(at least as far as the HP 5890A is concerned).
Figure 13-6 shows displays occurring either in verifying an INET address
set through automatic loop configuration or in entering a specific HP-IL
default address used when the HP 5890A is included in an HP-IL loop
without automatic configuration. The address is maintained in battery-
protected memory along with other instrument setpoints.
