I'm trying to use Agilent 34970A DAQ unit with three 34902 16-channel multiplexer modules to read 48-channels of resistance values. I downloaded the National Instruments driver for the Agilent 34907A and currently using it in the VI (please see attached VI). The VI works well when I select 31 channels or less but ran into problems when I increase the channels from 32 to 48. The DAQ unit is giving me a 521 error code (input buffer overflow). The DAQ unit is connected thru the RS-232 port with a USB-to-Serial cable.
Has anyone encountered similar problems?
Any Help or recommendation is appreciated.
Thanks!
