Good Morning All,
On a previous IHG call we spoke of some communication issues between newer Dell rugged Laptops/Tablets and SonTek M9s when using the supplied SonTek radio modem. We’ve seen the driver come standard with all newly purchased Latitude 5430 Rugged and 7330 Rugged systems and installed on some systems during the Dell Critical Update.
We’ve also reproduced the same communication issues when using USB-Serial cables that use a FTDI chip when trying to communicate with the M9, SL3G, and IQ.
The cause of the problem is due to a custom version of the FTDI driver that Dell is installing on their systems. Dell’s FTDI driver version will show as 2.14.1.6 or greater. The easiest way to fix the issue is to uninstall the driver and install the highest stable version posted on FTDI’s website (2.12.36.4). In the advanced settings of Dell’s driver “Serial Enumerator” has been disabled and “Enable Selective Suspend” has been enabled.
USGS has an open support ticket with Dell in attempt to resolve the issue. We have also included SonTek representatives in our correspondence with Dell to help with the process.
