The MAX110 Bit Manipulation Panel screen offers direct
control of the configuration word and gives a direct
view of the output data word. Note that certain bits of
the control word are used for factory testing and must
be zero; the program prevents these bits from acciden-
tally being set. See Table 8 for a list of commands.
The MAX110 program can store measurements in a file.
Once logging has been enabled, it can be started and
stopped from the Control Panel screen. The numbers
stored in the logging file are signed conversion counts,
which may be converted to voltage values by a simple
calculation.
To enable datalogging, start up the MAX110 program
using the command-line option “-L” to specify the out-
put filename. For example, the command “MAX110
-Lmyfile.dat” creates the file myfile.dat for logging. If
you specify the name of a file that already exists, the
program asks for confirmation before erasing the old
file. An “N” answer exits MAX110 without damaging the

Toggle the value of the PDX bit used in shutdown
mode.
Set the sleep time (the length of time the P command
will remain in shutdown mode).
Toggle whether a NO OP cycle should be performed
during wake-up.
Toggle the value of the PD bit used in active mode.
Toggle the value of the PDX bit used in active mode.
Toggle whether an AUTO NULL cycle should be per-
formed during wake-up.
Toggle whether a GAIN CAL cycle should be per-
formed during wake-up.
Enable or disable data logging. This command is
available only if the MAX110 program was started
with the -L command-line option.

FUNCTION
Data Logging
old file. A “Y” answer erases the old file. Once the old
file has been destroyed, it cannot be retrieved.
By default, both channels are polled. To log data from
only one channel, press the “1” or “2” key to turn off the
unused channel. To begin logging data, press the “L”
key. Logging may be suspended and restarted by
pressing “L” again.
The format of the log file is straight ASCII text, with one
reading per channel per line. When only one channel
is enabled, each line contains one reading. When both
channels are enabled, the readings for channel 1 and
channel 2 are separated by a comma. The channel 1
reading is logged first. If both channels are disabled,
no additional data is logged (see Table 9).
The numerical value written to the file is the signed inte-
ger conversion-count read from the MAX110. To con-
vert the conversion count to a voltage, use the following
formula:
Note that due to overrange, conversion counts may
extend beyond 16384 to approximately 21000.
