You have to select the port in 635_WinTest. Can you check that?

I have selected the port named "CrystalFontz CFA635-USB (COM7)".....
I changed the COM port from 4 to 5 to 7 etc.... rebooted un-installed drivers cleaned registry retried.....

if I press the packet button to see the window I get this in it:

tC=1( 1 = Read Version),L=0,D="",CRC=0x169F

I also tried the internal USB cable, External USB cable.
I took all the fans off the SCAB, No Temp sensors , still no luck......
Can the cable between SCAB and 635 cause the communication error? (I would not think so....)
Great looking display! Wish I would find a way to make it work.....

If the COM port shows up, and the display has power and it still will not talk at either baud rate, then something is not right.

Please give support a call tomorrow (888) 206-9720 and if they cannot figure out what is wrong, they will get another display out to you.

I have exactly the same problem with my 100 635 series M7Y.
The previous 4 I bought with series F7B has no probs.

Great and super fast support !

Thanks again,

Some CFA-635 units got some incorrect USB programming

Unfortunately, the hardware we use to program and test them reported that everything is OK during its check phase, but they do not work on a PC.

These units will have to come back for reprogramming. Please contact support@crystalfontz.com to arrange an RMA.

Please accept our apologies for this problem. Hopefully we can correct it for you quickly.
