VISA Serial read issues

Hi,

I am using LabView to read the resistance values from an AC Resistance bridge using the VISA commands basically copied and pasted from the Basic Serial Read and Write.vi and am currently running into an error:

VISA: (Hex 0xBFFF006C) An overrun error occured during transfer. A character was not read from the hardware before the next character arrived.

I was wondering how to fix this as well as turn the outputs of the RVAL command into a double.

Cheers
