That's ok, just got the dac a few minutes ago

However I paid 5EUR extra for the encoder extra pcb that goes with the small front controller and it was not into the box (just the PCB, I bought the encoder)

Can you send me the small encoder pcb into a mail envellop?

Thanks
SB
Yes for sure

Ok, thanks..

Just a quick question: (or two..)

Maybe You could clarify better the description at around J11, J13.
That is, the method of supplying an external feed.

Thanks again &
Ciao, George

J11 and J13.

For the isolated USB power on the board we use NTE0505MC.

If it gets removed it can be feed with external +5V with J11

J13 if an enable connector for extenal powersupply.

BR

Sonny

Aha.. J13.
Ok, so it is to synchronize the external-power -on sequence with on-board power.
Thank You!

With all the USB Audio DAC V1.2 we have supplied a RS232 female DSUB cable.

It fits directly into a standard USB to RS232 cable.

I would strongly suggest that you all get the SAM-BA V2.15 bootloader.

A link to the bootloader : sam-ba_2.15.exe

We have an USB to RS232 converter that we sell with the chassis.
Alternatively it could be a cable like : USB 2.0 PL2303 | eBay

The simple frontpanel is connected using a 0.5mm pitch 30 pin FFC cable Same side connector.

Würth part number:687 630 050 002 (50mm)
Würth part number:687 630 100 002 (100mm)
Würth part number:687 630 152 002 (150mm)
Würth part number:687 630 200 002 (200mm)

Molex P/N: 0151660333 digikey part number WM11402-ND (254mm)

Be careful when pulling up the Lock. If pulled to much it will break off.

On the picture it can be seen how the cable should be inserted. Be sure that it is installed in parallel with the connector a little off angle and it will not work.
