5.6 Customizing Acutime 2000 Operations
The Acutime 2000 provides a number of user configurable
parameters that allow you to customize the operation of the unit.
These parameters are stored in a non-volatile memory chip
(EEPROM) to be retained during loss of power and through resets. At
reset or power-up, the Acutime 2000 configures itself based on the
parameters stored in the EEPROM. You can change the values of
these parameters to achieve the desired operations using a variety of
TSIP packets. The Acutime 2000 configures itself based on the new
parameter immediately, but the new parameter value is not
automatically saved to the EEPROM. You must direct the Acutime
2000 to save the parameters to the EEPROM.
Parameters are grouped into sections of the EEPROM called
segments. Each segment is identified with a number and contains a
group of related parameters. To change the parameter values stored in
EEPROM, send packet 0x8E-26 to direct the Acutime 2000 to save
the current parameter values in a specified segment in the EEPROM.
You can also direct the Acutime 2000 to set the parameter values to
their factory default settings with packet 0x8E-45. When a segment is
set to its factory defaults, the contents of the EEPROM segment are
set and the Acutime 2000 configures itself with the default settings.
In brief, to customize the Acutime 2000 operations for your
application:
• Configure the Acutime 2000 using TSIP command packets
until the desired operation is achieved.
• Use TSIP packet 0x8E-26 to save the settings in non-volatile
memory (EEPROM.)
The new settings will control the Acutime 2000 operations whenever
it is reset or power cycled.
Tables 5-2 through 5-12 list the user configurable parameters by
segment number. Each table lists the parameter name, its factory
default value, and the TSIP packet that sets or reads the parameter
value (typically, one TSIP packet sets or reads several related
parameters.)
