Use the ±5V range;
Output a buffer a total of 800 hex entries long
Use the command:
AC3=8000,02,0F,00,0800[CR]
Set Calibration Parameters
CALn=bbbb,mmmm Write span and offset calibration values in two’s-complement hex
as two four-digit numbers.
Example:
Write a span of 42h and an offset of 36h to DAC 1
SEND: CAL1=0036,0042[CR]
RECEIVE: [CR]
Read Calibration Parameters
CALn? Recalls the scale and offset calibration constants.
Example:
Read calibration parameters after the above write
SEND: CAL1?[CR]
RECEIVE: 0036,0042[CR]
Store Calibration Parameters
BACKUP=CAL Backup the last calibration
This function stores the values required to adjust the measurement readings to agree with the last
calibration. The setup program will measure and write these calibration parameters. The
SAMPLE1 program illustrates using the CALn? Command with the results of this function.
Configure Bits as Input or Output
Mxx Configures digital bits as inputs or outputs.
Mx+ Configures digital bit 'x' as output.
Mx- Configures digital bit 'x' as input.
These commands program the digital bits, on a bit-by-bit basis, as input or output. A "zero" in any
bit position of the xx control byte designates the corresponding bit to be configured as an input.
Conversely, a "one" designates a bit to be configured as an output. (Note: Any bit configured as an
output can still be read as an input if the current value output is a "one".)
