Well I can't take credit for the Pi software - that's down to Evariste, F5OEO, who should be releasing a new SD image to the public imminently. All I did was design the TS_DOCK schematic and PCB. Carl M0ICS did the DTX1 firmware, and that IS available now at Beta as above.
I think Evariste's website http://f5oeo.fr/ is where you will be able to get it from. In due course we will with permission put it on our own DTX1 support site http://www.dtx1.info
As soon as I get more news I will advise everyone accordingly!
I see the TS-DOCK PCB's are selling in the BATC shop, which is great -
so for those who haven't obtained it already here's the link to the parts list (bill of materials) for assembling the board.
It's case sensitive.
Ah, the smell of solder flux...mmmmm.. wonder if that's how I contracted Asthma.....
After an initial delay while we tested it ourselves, here is a Beta version of Evariste's code for the Pi, to try : http://f5oeo.fr/RpiDATV1.2.1.img.zip
To use it on Model B Pi's unzip, write the image with win32sdimager onto an SD card, & plug it into a Raspberry Pi and then choose items on the menu via. the keyboard.
We have tried it here and it works very well. There are some continuity errors due to dupilcate PMT's (one from the Pi, one from the DTX1) which will probably be dealt with by a further release of Beta software for the DTX1. However the code is very useable as-is and decodes fine.
No further bulletins expected now until next week.
Please note, the interconnections listed previously between the DTX1 TS Dock PCB and the RPi are missing one vital connection - signal ground!
Please make sure you connect 0v on the Model B Pi (pin 6 of the 26 Way connector to 0V on the TS Dock pin 1 of the 34 Way connector).
For those of you who didn't make it to CAT15, you might like to know that the BATC shop is now stocking Version 1.1 of the TS Dock PCB. This has a 26 Way connector (as well as the 34) and the 26 Way goes directly 1:1to the Pi Much neater !
We would not expect the DTX1 to detect the TS Dock board - that's normal. (There are no I2C devices on it that the firmware can look for!)
If you think about a normal broadcast RF signal, it's a multiplex - after all you have but one aerial socket on your TV yet several 'channels' (really programs) now happily live in the same bandwidth as did an analogue TV station. Built into our DVB encoding FPGA there is a 2 channel multiplexer. The first input channel is connected to the MPEG2 encoder IC output on the main board, and the second one presented at the header into which you connect the TS Dock PCB. You need to 'tell' the DTX1 that there is a second channel in operation by enabling it in the menu system, and for DATV purposes it's usual also to disable the primary channel or you will in fact get a wider signal to air containing both lots of data! You also need to tell it that the clock is EXTernally sourced. There are then a few other parameters to input and tbh these can be a little tricky, but help is coming!
We are about to ship a new batch of DTX1's to BATC pending Noel confirming the exact default preset contents, and at that time (hopefully this week) we will also release the latest version of firmware to existing users which will contain that enhancement. You will need a simple RS-232 lead (Tx, Rx and Ground) to re-flash your DTX1. The latest version will be announced here shortly then, and will be found at http://www.dtx1.info/downloads/firmware/ along with the PC utility to re-flash the unit. A new batch of TS Dock PCB's will be shipped too (no design changes).

Thanks for the quick reply and a Happy New Year to you also!
I will await the new release, but an example of the problems that the non-expert has is when you say tell the DTX1 via the menu system it has a second channel; which menu, which option? It is not obvious to me! I can make up a serial lead, I think you use a 6 pin connector, rather than the 8 pin Ethernet type. I can cut one off an old telephone, but can you detail which pins are which at the DTX1 end, and are the rx/tx leads straight or crossed over?
