6K Hardware - Analogue Input Resolution

The analog inputs for the EVM32 I/O brick have a 12-bit A/D converter. The voltage range is +/-10VDC. The 12 bit resolution gives it a count range of +2047 to -2048 counts. If you are using the full +/-10 Volts, then 1V=205 counts. You can adjust the voltage range with the ANIRNG command. Below is a table that describes the voltage range options and how the counts/volt are adjusted:

When using the 6K Communications Server(COM6SVR.NET) via Ethernet, you can read the analog input voltage with the AnalogInput(channel) function. This will return a value in counts. You should use the table above to convert the counts into volts.
