Thumb DV Baud rate change #ambe #thumbdv #ambeserver


 

Sorry if this has been answered before, I searched but could not find it.
I have an original ThumbDV, its baud rate is 230,400. My new ThumbDV has a baud rate of 460800, Is there a
hardware (relative easy!) mod to bring the original up to 460800 ?
Thanks

Don,


Changing the baud rate is not trivial.  Is there a particular reason you wish to change it?

Hi Don. I recall reading a how-to from John Hays of NW Digital Radio, where he explains how to do "surgery" to an Original ThumbDV to change the baud rate from 230,400 to 460,800, I believe that it involved in cutting a couple of traces on the PCB and re-jumpering.
I'll see if I can locate the document.

I see that John has replied.  I forgot to add that the procedure is not for the faint of heart, which is why John has asked why you wish to do it.

Hi John,
Yes, I would like to have my original one and my newer one run at the same baud rate
for a transcoder project.

Would you be interested in swapping your low speed unit for my high speed unit?

That would be an excellent solution, should you decide to do so.

Let me do a little research and get back to you.

Gary,
Yes, I would as the task to change the band rate is quite intensive.
They are identical except for the band rate.
I will await your research.
Please let me know.
