Firmware Updates
System Firmware
The system firmware (S37) is the most common type of update. It’s a small file and doesn’t take too long to
update.
In the 232-ATSC+1, you won’t need an RS-232 port. Just download the .zip file from our website, open the
ZIP folder, then copy or drag the file to a pop-up file window, just as if the tuner was a memory stick.
