GETTING STARTED
ACE100DS REV. E JAN 2007
ACE100 QUICK START
:
1) Connect the power supply inputs to the ACE100.
2) Connect the DB9 serial cable to the COM1
connector on your PC.
3) Set the jumpers on the board for the analog input
signal to be “External” or “On Board”. If external,
the input signal should be connected to the
IN LOW and IN HIGH terminals. If the input signal
is from the on board references, set the voltage
jumper to the desired voltage.
4) Set the ADC select jumper to ADC150 for
ADC100 and ADC150 operation, or to ADC180
for ADC180 operation.
5) Copy files from the CD to a local directory. The
files to run the program are the ACE1xx_Eval.exe
and the MSCOMM32.OCX. The MSCOMM32 file
is the file for the serial communication port and
need to be in the same directory as the
ACE1xx_Eval file.
6) Turn on the power supply and let the ACE100
warm up for 5 minutes.
7) Double Click on the ACE1xx_Eval.exe file to start
the program.
8) AutoZero the converter to remove any offset drift.
Running the ADC180:
1)
If the continuous operating mode is selected,
the data samples are sent to the program
display. The batch mode first collects the
samples to the on-board RAM and then
transfers the data to the display. Due to the
limited speed of the RS-232 com link, the
continuous mode may not display all of the
samples if the conversion rate is too fast for
the com link (the number of integration cycles
is too small). By writing the data to the RAM,
higher conversion rate data can be collected.
2)
The number of samples and cycles per
sample must be filled out. The number of
cycles per sample will determine the
resolution and conversion rate of the
converter. See the ADC180 datasheet for
more details.
3)
To save the data to a file, check the box and
select the directory. The data will be stored
as a text file named ADCdat.txt.
