What DCH model?
Could not get any output from serial port of dch-70, but never tried with dch-3200.
I just found TDI of dch-70 and jtag now works!
Pretty sure jtag works on dch3200(same cpu as dct, but different revision), just need to add missing pull-ups, but again I have not personally tried it yet.

Error 404, Page not found, Sounds familiar?
That would be true if you have erased some cells from your brain as many useful links and pages were deleted from this forum for a known reason.UserName wrote:everything i know should be in this forum...

sorry but i test by serial and never see the way to program key.UserName wrote:jtag is good for recover nvram and software.
serial is used to program keys ....they all are encrypted commands.
only dct2000 with USBDM software spicommand and so, but dct700,dcx700,dcx3400 NOT...or you have the way ???

The Serial Interface is there
You don't need a TV PassCard interface to connect to DCH3xxx boxes. The serial connection is there, on the back, phono jack 3.5mm. You must have 4 connection jack (3 + ground) in order to keep the serial connection alive. A jack with 2 + ground connection disables the port. The third ring must be left open in order to enable the port. There is also no need of RS232 to TTL converter (as the TV PassCard is) because it is already built in onboard (U506 MAX3221CDBR). Unfortunately to enable this port for testing you need a diagnostic code loaded and you also need a secret key (token).UserName wrote:still nobody found serial interface for this dch boxes like the tvpasscard.
On the other hand there is another serial port (onboard) for debugging purposes (4 pins header J407) that connect to U402C which is a peripheral IC for UART and SPI connections.
As far as DCX3400 boxes, the JTAG connection is disabled by the firmware. Only loading the diagnostic code allows JTAG connection.
At last, what can you achieve if you even enable all those ports, the M-Card must be paired in order to work with a box. Without valid keys into the M-Card and paired host serial number (activated) you won't get much out of it.
