RDAG12-8 Manual
RECEIVE: [CR]
Stop Buffered DAC Outputs on DAC n
An=STOP Ceases writing DAC n buffer to DAC.
Example:
Immediately cease pattern output on DAC 5
SEND: A5=STOP[CR]
RECEIVE: [CR]
Set Acquisition Rate
S=xxxx or s=? Set or read acquisition rate ( 0100 <= xxxx <= FFFF).
This function sets the update rate of the DAC. Valid values range from 0100 to FFFF. The value
passed is the desired divisor of the rate clock (11.0592 MHz). The equation to use in calculating the
divisor is:
Divisor = [Clock/12] / [Rate], or 921000 / Rate
Example:
Program the RDAG12-8 for 1K samples per second
SEND:
S=0399 [CR]
RECEIVE: [CR]
Note: The sample rate configured is stored in EEPROM on the Pod, and will be used as
the default (power-on) sample rate. The factory default sample rate (100Hz, or S=2400)
can be restored by sending “S=0000” to the Pod.
Configure Buffers and DACs
ACn=xxx0,dd,tt,mm,iiii
xxx0 is the desired power-on (initial) state of DAC n
dd is the divisor for the output rate (00 <= dd <= FF)
tt is the number of times to run
mm is the polarity and gain select for DAC n
mm = 00 = ±5V
mm = 01 = 0-10V
mm = 02 = 0-5V
iiii is the buffer array entry (000 <= iiii <= 800h)
Example:
To configure DAC 3 to: Power on at 8000 counts;
Use one half the Sxxxx timebase as its buffered output rate;
Output the Buffer a total of 15 times, then stop;
