New Features of the AcquiSuite/AcquiLite's LCD
Together with support for USB modems, the LCD console of the AcquiSuite/AcquiLite DAS has several new features to aid
in debugging and diagnostics of dial-up connections if a PC and web-browser is not available.
The new LCD behavior is intended to be very intuitive and simple, but for the sake of completeness it is described here.
First, status events from the dial-out, dial-in and the data-upload processes will preempt the DAS's normal message
rotation, unless the user pressed either the MENU or SELECT button in the last 3 seconds, or the user is currently in one of
the DAS's LCD menus.
These status messages remain on the LCD for 30 seconds, then (assuming no new status event occurs), the DAS returns to
displaying its normal message rotation (e.g. showing its IP address, the timezone and current time, and any errors from
Modbus devices).
Examples of these status messages are given later in this document.
Second, at any time the user may HOLD DOWN the SELECT button to “hold” the display. Holding SELECT stops the
normal LCD message rotation and stops the LCD being preempted by any new status events. While SELECT is held, the
display also scrolls at a slower rate to allow for easier reading of the LCD message.
Third, the most recent status event (if there is one) will appear in the normal message rotation, and the user can review these
messages in the normal way (by pressing SELECT to step through them). Typically, the status message will be either the
last modem error, the last upload error or an upload success message.
