Enables or disables the corresponding input channel 0, 1, 2, or 3. The EV kit software scans all enabled channels.
Displays the conversion results in decimal form.
Delay between samples. Delays longer than one second are handled by the IBM PC; otherwise, the µC module
handles the delay. Timing is approximate and should be verified with an oscilloscope.
Enables or disables data logging. If the -L command-line option was not specified, the L command prompts for a
log-file name.
Oscilloscope demo. Samples are collected and discarded as fast as possible. Observe waveforms and timing with
an oscilloscope.
Power-up delay. Timing is approximate and should be verified with an oscilloscope. When using an external refer-
ence, power-up delay is not necessary and should be set to zero. Power-up delay is used regardless of which
power-cycling mode is selected.
Samples one of the four inputs at high speed. The sampling rate is controlled by the P and D delays. Due to pro-
gram overhead, the O and S commands operate at different rates. Timing should be verified with an oscilloscope.
Displays the conversion results in volts.
Selects input scale (unipolar, bipolar, unipolar differential, bipolar differential) for all enabled channels. Disabled
channels are unaffected.
Writes a marker into the data-log file.
Measures the value of a user-applied COM voltage.
Changes the assumed value of VREF.
Changes the assumed voltage at COM. Selecting G connects the COM pin to ground; selecting E connects the
COM pin to the EXTCOM input pad.
Internal clock mode
External clock mode
Selects power-down mode.
Switches back to terminal mode.
Exits to DOS.
Enables the fast power-down mode
for the MAX1246.
Defaults to COM1 PC serial port.
Defaults to COM2 PC serial port.
For use with monochrome or LCD
display.
Opens file filename for data logging
and enables the data-logging
commands.
Specifies the actual measured volt-
age at the VREF pin (nominally 2.5V).
Specifies the voltage at the COM pin.
Lists command-line options.
