3.4 System and Device Initialisation
Internal memory and functions tests are performed at the large format
display during power-up (duration: less than 1 second).
If the display is not illuminated (and if the integrated functions LED
blinks slowly, i.e. 1 Hz), the device is in the boot mode. This indicates
that the software or the configuration data currently stored to the inte-
grated flash memory are incomplete. This may result from a previously
interrupted upload operation. If this is the case, uploading must be re-
peated (with the help of “MICON” PC software).
If the test mode has been activated (S 4), a series of checkerboard pat-
terns is displayed in a cyclical fashion.
If the test mode has not been activated, the following parameters ap-
pear at the large format display, depending upon the HEX switch set-
tings at the device:
Device address (ID)
Baud rate
Number of data bits.
Type of parity bit
Number of stop bits
After power-up, the first macro is executed (if one exists). If the display
unit is to be cleared again immediately, a corresponding macro must ex-
ist!
The display unit then waits for valid output data from the user (via the
serial or the parallel interface).
