Analog Output Formats
You can configure ADAM analog output modules to receive data from
the host in Engineering Units.
the host in Engineering Units.
Engineering Units
Data can be represented in engineering units by setting bits 0 and 1 of
the data format/checksum/integration time parameter to 0.
the data format/checksum/integration time parameter to 0.
This format presents data in natural units, such as milliamps. The
Engineering Units format is readily parsed by the majority of computer
languages as the total data string length is fixed at six characters: two
decimal digits, a decimal point and three decimal digits. The resolution
is 5 µA.

Example:
Channel 1 of the analog output module in slot 0 of an ADAM-5000
system at address 01h is configured for a 0 to 20 mA range. If the
output value +4.762 mA is desired, the format of the Analog Data Out
command would be #01S0C14.762<cr>
