Hello Hans, to get a volume range of -63dB to 0dB, I have to use R14/R34=2K, right? The relais you are using, are they smd or thru hole? Thank you Thomas

Hi Thebo,

Yes 2K for 0dB max is correct.
The Relais are through hole, see here:
IM23TS - TE CONNECTIVITY - Signal Relay, IM Series, DPDT, 5 VDC, 2 A, Through Hole, Non Latching | Farnell element14|

Now that everything is starting to move with the Maya Controller and the VolCB etc, I had a short communication with Tibi to check if everything was still the way it should be.

We came to the conclusion that the Maya firmware for the 6 input GB board has still to be adjusted, enabling 6 instead of 4 channels.

There are 2 ways that can be taken:
- First is by delivering everybody the Maya controller with the current 4 input Firmware-1, and to supply the adjusted Firmware-2 at a later stage where everybody has to do the firmware change from 1 to 2 by himself
- Second possibility is to let me test the new Firmware-2 and to supply everybody with the Maya controller with this new firmware-2 after my O.K. has been given, avoiding users to do the firmware change themselves.

Everybody with the BPBP could, but must not use Firmware-2, except for those with the 6 input board, they MUST have Firmware-2.

To my opinion it would be better if ALL BPBP have Firmware-2, since one Firmware version makes support quite a lot easier.

What it means to flash the Firmware, look here:

Just to add to my previous email.

I have already prepared myself to do the testing of this new Firmware-2 version, by ordering the Atmel mini USB programmer.
As soon as I have the Maya Controller and the VolCB PCB, I will only need a very short time for testing.

Hi Hans,
I noticed in your BOM you specify a G6K-2P for RE7. Any reason for using a different relay here from the others?
Thanks

You could eventually use the same IM23TS for Re7 just as the other six relays, but then you will need to do some bending, since the IM23 has 3.2/2.2/2.2 mm pin distance and the G6K has 2.54/2.54/2.54 mm pin distances.

Reason for this G6K is that when using a 4 input or a 6 input board, this relay is replaced by a socket using partly the same holes in the PCB as the relay.

OK, so I assume when using the 4 input board Re7 is not used and replaced by a header.
I have purchased the 4 input board from Tibi as well.

That is correct.
RE7 is needed only in case of using the standard 2 input version of the BPBP.
For the 4 input and the 6 input add on's, header 2178710-8 has to be used instead.
