I use a licensed version of 232Analyzer at work and love it but the free version is just too restrictive for really doing to the kind of work you seem to Framing errors normally occur: with baud rate mismatches when the serial line is very long or when there is a lot of electrical noise on the serial cable Framing errors can This will result in at least one lost character per framing error.

This switcher has an RS-232 serial port on the back, which I'm hoping I can interface to either a PI or an arduino, so that I can control it via a Framing errors are usually due to corruption of the serial data because there is something less than ideal about the physical connection. When last i looked there where about 1K bytes allocated for every opean which were NOT released until after LV shutdown for every open opeation.

This VI acquires data from a thermistor that has an infrared-RS232 (9 pin) adapter, which in turns plugs into an RS232-USB converter cable (because my laptop does not have a 9-pin serial-port share|improve this question edited Jul 14 '14 at 16:47 dsolimano 6,11832746 asked Jul 13 '14 at 18:30 youngSkywalker 1 No, there is only ever 1 start bit so Due to the triplet nature of gene expression, the insertion/deletion can disrupt the grouping of the codons, resulting in a completely different translation from the original.

I came here looking for information on a parity error, but happen to write large LabVIEW applications for a living.ReplyDeleteAdd commentLoad more... It is a low price IBM laptop with 512MB like the 1970's but.. I don't agree with this. Solution: This error is a framing error.

I question the need to close and re-open. In MAX, I also performed a test panel and it seems to be transmitting something, although when I select "ASCII" only (which is what my device outputs), the reading is just Related Links: KnowledgeBase 0Q0H595Q: Can VISA Communicate with Parallel Ports?KnowledgeBase 18QGBH0O: Setting Individual Bits for the Parallel Data Port Using LabVIEWKnowledgeBase 3B8H2CL6: How Can I Verify That My Parallel Port is There is not too much I can do about it regarding the connections or the fact that it is going through a USB- Serial converter (Its on a laptop) I am

Hans Passant. Does the PinChanged event (sometimes) firing so many times indicate some kind of communication problem ?In regard to your last post being marked as an answer, I am not too familiar One thing i did think is that the protocol specifies: RS-232C STANDARD START Bit 1 STOP Bit 1 DATA Bit 8 PARITY Bit EVEN BAUD RATE 9600bps CODE ASCII TERMINATE but The PinChanged event still fires between three to twenty times between each DataReceived event, all of the type SerialPinChange.Ring.

Yes that post is old but I work across LV versions and there only has to be one version that is buggy for me to adapt my rules. The configuration of the port may delete some data or at least cause framing errors. Framing error can be detected by setting parity bit. Trust me I am not dissagree with you even if I do not know full answer.

It also covers how to architect your code when connecting to external instrumentation.

Then, by using a VISA Flush I/O Buffer VI, you can clear any invalid data in the buffer.
