The GPIO Definition Table
The GPIO Definition table has been modified to accommodate additional
Sub systems for the EAS messaging option; the new GPIO Sub systems are
EAS Messaging Warning, EAS Messaging Watch, EAS Messaging Test and
EAS Messaging User1 thru EAS Messaging User12.
The GPIO Definition hyperlink can be found in the 5th Step: Input/Output
Sets area. The GPIO Definition table (
Figure 313 ) will appear after clicking
this hyperlink.
Note If EAS Messaging is not configured, then this table cannot have any User
defined levels.
