Meridian Unplugged - Powered by MrTechGuy.co.uk Forums Discussion Meridian - Systems 596 firmware

First, there is no substitute for a real serial port. I recently helped someone update firmware on 7 DSP speakers, 561, 596 and configure 4 DSP-33 and the 561. Not 1 single hiccup. Because it was on a real serial port.

I personally have both and the USB is fussy and works most of the time. But not as realiable as real serial.

The problem is no hand shaking is used. It assumes the PC can keep up. Poor USB Serial emulation drivers are the common cause.

If it asked to reboot the 596 then it sounds like it is talking.

Sometimes trying a bunch of times works. I have a few times had it failing tried 10 times and then the 11th time it suddenly works.

Make sure you close down all uneccessary apps. Try turning off Virus Protection (they can slow computers down).

The latest MConfig has a workaround to slow things down. But I don't believe it's applied to firmware updates.

There is also some older command line upload programs. They are in C:\Program Files\Meridian\Meridian. You must open a "Dos Window" (command prompt) to use these.

Try using this at a slower baud rate than the default.
