Can't talk to BK8500 after upgrading to LV2013

[drjdpowell]

I'm also working with a BK8500 and have problems getting data back.   The LabVIEW driver is terrible; it calculates things like checksums but then entirely ignores them, never returning an error or retrying garbled commands.   I'm trying to fix the driver, but I still can't get any response from the unit.   Anyone got these to work well?

zou: "The driver is not working correctly.  End up making a lot of change ourselve."

zou, please, could you share here your modified drivers?

I have also problem with using it on Win7 / LabVIEW 2012

So I solved it by using 9600 baudrate. Make sure that baudrate is set properly everywhere...

Device:

Go to MENU - CONFIG - BAUDRATE SET : 9600

Check Windows drivers and MAX setting.

Also check if system decimal point is set to "." (point, not comma). Drivers are sensitive for that. (e.g. Four bites to Number.vi used in Get Value.vi)
