• (As of version DLL 520:) ASC hardware checks are performed not just via
auto_cal
(
Command
= 4), but also automatically for
–
auto_cal
(
Command
= 0) and
– the first call of
auto_cal
(
Command
= 1) and
auto_cal
(
Command
= 3) if neither
auto_cal
(
Command
= 0) nor
auto_cal
(
Command
= 4) were previously executed.
In each case, the detected ASC hardware type gets stored in the RTC
®
5’s EEPROM and
can be subsequently queried via
. For automatic
Command
= 4 execution,
however, no corresponding return value is generated. The return value is instead simply
that of the primary
Command
call (see above).
When an error occurs, a corresponding error code will get saved to the RTC
®
5 EEPROM
(therefore,
won’t return 100 or 200). As soon as hardware functionality
is restored, you can clear the error from the RTC
®
5 EEPROM by explicitly calling
auto_cal(command = 0)
or
auto_cal(command = 4)
. The error
can’t
be cleared from the
RTC
®
5 EEPROM by calling
auto_cal(command = 1)
.

Command
= 0 …2) are (largely) unchanged
(see version info).
New:
Command
= 3 and
Command
= 4.

Comments
• The
auto_change
command is synonymous with
auto_change_pos( 0 )
. The subse-
quent list will then start at its beginning.
