A few more tips - these work, as I built a new one this morning.
Down load the software from the link in Brian's post and create an SD image using win32diskimager =
http://sourceforge.net/projects/win32diskimager/
Connect using Putty or directly and log in:
User = pi
Password = tv
This will boot the install menu - choose English (or French). It will reboot and take a couple of minutes. If you have an si570 local oscillator, copy Brian's program using an FTP program in to the home/pi/RpiDATV directory.
Re-connect using putty or a monitor and log in again - type "cd RpiDATV"
Start the si570 on 146.5 MHz (or wherever) using Brian's command line.
Now type "./gbmenu.sh"
This will start the RpiDATV menu. It will give a status screen and by default is running in Ugly mode at 1Msymbol using Evariste's callsign in the SI.
Press return to enter the menu and to use with Digithin set the following:
select source select using up down keys and press return - hopefully you will have a camera connected, if not you need a .ts file recorded at the right bit rate for 333 Ksymbols = 460 Kbit/s.
Up down to select the camera, hit space bar and then return. Should return you to the status menu.
Hit return and now select output select
Select symbol rate and enter 333
Takes you back to the status screen - hit return and select output select again
Select output mode and hit return
Several interesting choices including BATV stream, DTX1, DATV express, direct RF on 437 = ugly mode and Digithin which is the one you want - space bar and return.
This should now be driving the Digithin card and the Digithin thin LED should be flashing at 1 second intervals.
The display on a spectrum analyser (or SDR#) etc will change from a carrier to a modulated signal.
You probably want to change the callsign using the 3rd option.
The RpiDATV program will now boot to this state every time and you do not need to connect to configure it, however you will need to autorun the si570 program.
Hope this helps
