Table 3-6: Commands via RS-232 Input
Command Description
as<enter> Immediately starts an autospan
az<enter> Immediately starts an autozero.
co<enter> Reports "Sensor Output" (voltage
output of the sensor itself) inVDC
For example—
Raw Sensor Output: 1.000 volts
st<enter> Toggling input. Stops/Starts any
status message output from the RS-
232, until st<enter> is sent again.
The RS-232 protocol allows some flexibility in its implementation.
Table 3-2 lists certain RS-232 values that are required by the 3010MA
implementation.
