It has always worked no matter the operating system or software being used. I have customers (I’m in the marine electronics business) who have bought cheapy knockoffs and can’t get their pc integration to work properly. I sell them a USA-19HS and without any other changes, other than the proper driver install, everything works just fine. While it is more expensive than a $5 Chinese clone, how much do you value your time and peace of mind. Is it really worth the frustration with something that is supposed to be an enjoyment just to save a few dollars?<div class=""><br class=""></div><div class="">73s,</div><div class="">Jim K2SON<br class=""><div class="">

Anything else,<span class="Apple-converted-space"> </span><br class="">including Prolific, is a gamble with poor odds. It's that simple.<br class=""><br class="">Background: On our sailboat, I do a number of serial/USB conversions.<span class="Apple-converted-space"> </span><br class="">This converts (admittedly ancient) NMEA 183 serial data from<span class="Apple-converted-space"> </span><br class="">instrumentation for a USB port on a laptop running a navigation program<br class=""><br class="">(Coastal Explorer - don't leave port without it). Initially I used<span class="Apple-converted-space"> </span><br class="">Prolific-based convertes (what did I know?). Simply put, it became one<span class="Apple-converted-space"> </span><br class="">non-stop headache. Data wouldn't come through, drivers stopped<span class="Apple-converted-space"> </span><br class="">functioning, etc., etc. I switched to an FTDI-based 10-port serial/USB<span class="Apple-converted-space"> </span><br class="">converter. The only changes to the system was to plug the DB-9 pigtails<br class=""><br class="">into the new converter and load the FTDI driver.

Another port sends position, time<br class="">of<span class="Apple-converted-space"> </span><br class="">day, waypoint location data and receives target data from the radar<span class="Apple-converted-space"> </span><br class="">including Modified Automatic Radar Plotting Aid data. The last active<span class="Apple-converted-space"> </span><br class="">port receives data from the Automatic Identification System and an<span class="Apple-converted-space"> </span><br class="">auxiliary GPS receiver (part of the AIS system).
