Ok here's another round of dumb a*& questions.
I'm using a DaqBook/200 with DaqX software version 7.12.10 "latest and greatest except for the differential bug" I used their Daq* Configure Utility to set my DaqBook up. I created the following:
Device Name: DaqBook0
Device Type: DaqBook/200/260 (you pick this from a pull down menu)
Port (parallel) setup: LPT1
Protocol: Standard 4-bit
Having never used a Data Acquistion box before I tried to start with the simplest VI configuration I could find. I decided to use the "AI SAMPLE CHANNEL.VI". There are only five connections.
1st. Called "Device" this is the number I assigned to the Daq device during configuration. Now this should be what I typed above beside Device name: DaqBook0 "but I can only enter a number it want let me enter letters so I really don't know what to enter here now"
2nd. Called "Channel" identifies the analog input channel you want to measure. Using the DaqView software there are several columns that have names. The 1st column which you can't edit is labeled CH. Underneath is written P1 0 Direct. This means P1 (port 1 on the daqbook which is the analog port) 0 (which is channel 0 or the first channel) then the word Direct (meaning a direct connection to the Daqbook. Now next comes the "On" column which indicates if the channel is on/off. Next is the "Type" column this indicates if the channel is analog, digital, or frequency. Next is the "Polarity" column where you select either Bipolar/Unipolar. Next comes the "Label" column where channel 0 is labeled CH00 (by default)or you can enter a custom name. Then "Units" which indicates what type of measurement voltage, amps, counter, etc... The "Reading" column that indicates the output of that channel if DaqView is used as a stand alone.
Now out of all the columns above I'm not sure which to enter as the Channel as requested by the Labview VI above.
3rd. Called "High limit" this is the highest expected level of the signal I want to measure. This I think I can understand.
4th. Called "Low limit" this is the lowest expected level of the signal I want to measure. This I think I can understand.
5th. Called "Sample" contains the scaled analog input data for the specified channel. I know this is the data being measured, but I'm not sure what they mean by "Scaled"
Ok now that you know the information here's how I entered it.
Device- I put 0 because it wouldn't let me enter alphanumerical units. Help showed "I16" as the representation units. So I figured thats what I needed to enter and it could be change.
Channel- I enter CH00. I just could see entering a value that could be changed and the "P1 0 Direct" under the "CH" column just didn't seem right. But who am I to know.
High Limit- I set to 10.000Volts ( because I'm using a 9volt battery as a voltage source)
Low Limit- I set to 0.000volts
Sample- I just used an indicator to show the results.
When I run the VI I get the following error 10401 telling me that the specified device is not a National Instruments product, the drive does not support the device. Which I'm sure you know the error and the reason that it occurs.
So what do I need to start on first? Let me know
