RE: SLs (and I will add IQs). Communication can be affected by the USB drivers in newer Dell Rugged laptops if the FTDI USB to serial adapter is being used. Check your driver version and the FTDI driver thread for driver updating instructions. For issues not related to the driver, we have recently released IQ software v4.0 and firmware v4.0 with improvements to the recorder handling and SDI-12 communication. See post here for more detail: https://internationalhydrometrygroup.org/forums/topic/sontek-iq-software-and-firmware-version-4-0-release Long term beta testing has shown v4.0 is stable and reduces intermittent communication and recorder issues. SL software and firmware with the same improvements will be released later this year.
Sorry for the multiple posts, but there seems to be a word limit per post and no alert if you are over, it just doesn’t post.
