Are you sure you are lined /set up to the Sat correctly with the weak tuner box?? and your cabling is good??

      Many thanks for your prompt reply JBVID... cabling and setting is ok as other 2 dm500s have signal at over 80%... it is just a weak tuner that with my incredubility look like does not exist but 1 of the other two is the same and work at 90% signal.... Yes i have flashed sfteam images but same problem start with the sfteam initial screen in B/W and then i couple of grey noisy then black screen... no light and cannot ping.... only noticed that 2 light of network are steady on but there is no3rd flashing light.. I feel is a problem with the video output... does anyone know which IC control the video output please ?

        Hi
        Can't help much on the internals of the faulty tuner box, may be time to think about a replacement if you need 2 or 3 good working ones, take a look at the post by Alun above, the clones are cheap enough.

              Hi
              Why not try the 'jtagwin5xxx' (Windows version) in the downloads section??

                  Hi
                  You should be able to get a connection if you keep trying different delay times or try it on another PC.

                    Marcelo, it is enough to read my post....

                    like you, i could not connect with windows program and then what i did? i read 34 post and that gave me the solution as naother bloke suggetsted..... My p3 500mhz was too fast!!!!!. I run the antivirus which slowed down the pc and connected straight away... it would be better if you have a 166mhz pc!

                          i used a null modem cable for dreamup many times and not found any problem.

                          i just found a problem first time.

                            Hi
                            Try a different null modem cable, then another PC, you are not getting a ''connection'' to send data to dreambox , hence 'waiting for acknowledgement'.
                            You could first make sure correct com port selection is active in Device manager and same as dreamups, and try different versions of Dreamup
