Problems with 8-bit serial output...

[Bonhomme]

Hi there,
I've been reading posts on sending binary data out through a serial port and it seems that using the Byte Array to String converter with the Serial Write VI has been working well. Sending 7-bit values 00 through 7F has been fine. However, when I sometimes send out data to my device, the data gets unstable when using values 8F through FF. Has anyone had problems with that eighth bit when sending serial output? Just wondering if it's "fixable". Thanks.

You did configure the serial port to 8 bit output didn't you? I have had no problems with 8 bit data.

Sounds like "7n1"- or "7e1"-protocol.
You should choose "8n1".
