ThumbDV™ – Model A

by John Hays 

Beginning with orders placed after July 9th, 2015 a new revision of the ThumbDV™ will be shipped.

The only difference between the original ThumbDV™ and the new model 'A' is that the USB serial port will now operate at 460800 baud instead of 230400 baud.  Programs like WinDV, DummyRepeater, and AMBEserver have been updated  to support both baud rates.  It may take a few days for DummyRepeater to be pushed out with the change.

There is no change for D-STAR applications except selecting the faster baud rate.

Note: At this time we recommend using DummyRepeater with 'AMBEserver -n' (-n is for new baud rate) for best performance with model 'A'.

The latest source for AMBEserver can be found at GitHub.

Why are we changing the baud rate?

NW Digital Radio has been working with some OEM customers who will be integrating the ThumbDV™ into their products, including DMR based systems, and their existing programs use the higher baud rate to communicate with the AMBE3000 chip.  Moving to the higher rate allows these customers to more quickly integrate these systems.

Will older ThumbDV™ devices continue to be supported and sold?

NW Digital Radio will support ThumbDV™ both original and 'A' models.

Our inventory of original ThumbDV™ dongles sold out on the same day that the new model 'A' was delivered from the Washington State assembly house.  We do not plan to manufacture any additional 230400 baud 'original' ThumbDV™ dongles.

All new orders will receive the ThumbDV™ model 'A'

What about the DV3000?

There are no plans to move the DV3000 (GPIO) to a different baud rate.  However, it is relatively easy for the user to modify the boards to support additional baud rates through trace cutting and jumpers.
