– select sensor A:

STX a CHR$(25) ETX

– lock sensors

STX u CHR$(200) ETX (set programming time)

STX l 7 0 6 0 5 1 1 1 ETX (LOCK-ERASE)

4.2.1.

Monitoring of the Programming Voltage

In case of ERASE, PROM, and LOCK, the programming pulse voltage is measured by

the board, and a data string is sent back to the PC. The relation between the data and

the programming voltage is

If the programming pulse voltage is out of the specification limits, the status bit is set to

“1”.

Examples:

–VPROG = 12.15 V, Data board PC:

STX 1 0 D 0 A 0 ETX

(DAT = 0 D 0 A)

–VPROG = 12.50 V, Data board PC:

STX 0 0 D 6 9 0 ETX

(DAT = 0 D 6 9)
