Choose input scale (bipolar 10V, unipolar 10V, bipolar 5V, unipolar 5V). The currently active scale is shown underneath
the bar-graph display.
Enable or disable the corresponding input channel 0, 1, 2, 3, 4, 5, 6, or 7. The EV kit software scans all selected channels.
Display the input codes in decimal.
Display the input voltages.
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.
Select standby, fast power-down, SHDN power-down, or no power-down.
Power-up delay. Timing is approximate and should be verified with an oscilloscope. Power-up delay is used
regardless of which power-cycling mode is selected. In standby mode, power-up delay is not necessary and should
be set to zero.
External acquisition time for use with slow op amps. Timing is approximate and should be verified with an oscillo-
scope. The MAX197 is placed in standby mode during acquisition time.
Internal clock mode. Timing is controlled by capacitor C11. JU4 should be closed when using this mode.
External clock mode. Clock must be provided at EXTCLK input pad. JU4 should be cut apart when using this mode.
Oscilloscope demo. Samples are collected and discarded as fast as possible. Observe waveforms and timing with
an oscilloscope.
Sample one of the eight inputs at high speed and upload to a user-specified file. The sampling rate is controlled by
the P, A, and D delays. Due to program overhead, the O and S commands operate at different rates. Timing should
be verified with an oscilloscope.
Tare (offset voltage null). Assumes that channel 0 is connected to AGND. Measures the code at channel 0 and
subtracts that value from all subsequent readings.
Cancel the Tare (T) function.
Enable or disable data logging. If the -L command line option is not specified, the L command prompts for a log file
name.
Write a marker into the data log file. (See the Low-Speed Data Logging section.)
Switch back to terminal mode.
Exit to DOS.
