jtag connection diagram?

[nashnoush]

Can someone please post where the jtag connections go for lifetime ultra so I can jtag my fortec. It's rolling b75 over and over. Tried to load b75 bin to make it stop but not accepting any download. Tried Gtrom, Blacklist and fortec updater, none of them is able to write to the receiver. Also tried puff files to see if I can convert back, but still no success. I converted this unit way back to b75 and it was working fine. I installed the auto free Japan file and it was working for a while then it start rolling b75. I soldered pins to the receiver according to diagram I have from N2 era, but the file doesn't include were the jtag pins should go on the receiver. I appreciate any help if someone knows where the jtag pins go on the receiver. I already have the receiver diagram, I just need where to plug in the jtag pins. Thank you

You can try googling how to make a jtag cable, the pin varies between the 10 pin and the 20 pin

[Mr Hanky]

Try this 17682

Either someone has a very old computer or stores a lot of info :D I haven't seen that diagram in years
Try this 17682

[nashnoush]

Thank you, pugsycan. I will try it tonight and let you know

Wasn't me it was mr hanky

Thanks hanky. my jtag pins that connect to the parallel port on the pc are #2,3,4,5 and 13 and the rest is connected to ground. I'm not sure which goes to what on the 20 pins diagram of the fortec. Any help would appreciated.

For 20 pin jtag cable

DB25 male connector
Pin 2 » 100ohm » JTAG Pin 9
Pin 3 » 100ohm » JTAG Pin 11
Pin 4 » 100ohm » JTAG Pin 13
Pin 5 » 100ohm » JTAG Pin 19
Pin 13 » 100ohm » JTAG Pin 15
Pin 18-25 »-------------» GND

[Mr Hanky]

Ground is towards the edge of the board,the rest are obvious.I have the jkeys walls etc if you need it.lmao pugs.

[zelig]

you never put a resistor on ground.

[zelig]

TDO I have seen some simple ones with a 33 ohm resistor instead of 100 ohm,since it's an output from the tsop and not an input

[nashnoush]

Thank you dish expert. That's exactely what I was looking for. I do have wall and jkeys and all necessary files for the fortec. Also, thanks zelig for the thumbnails,very usefull. I will try it and let you all know of the result.

[SKYWARD1]

I have 100 ohm resistors on my Jtag and everything zelig shows in diagrams are correct I have done a few Fortecs and Pansats with mine, all work well with proper file and Jkeys or wall.:thumbsup:

[nashnoush]

I can't seem to get this fortec respond to jkey. It still saying check connection. I have 2 jtags I tried them both, I even soldered the cables directly to the fortec pins and still not able to read the tsop. I think I am going to use it as a door stop. But the problem is, it's rolling the b75 and I should be able to just use straight cable to program it. Even with that hooked up, using all kind of loaders, blacklist,gtrom and fortec loader and still no success.My question is, Is the b75 file is an indication that the fortec was converted to pansat 2700?

[SKYWARD1]

Hey Nash
Been awhile since I played with the fortecs and panny's , On your jtag plug did you solder a wire to ground side pins on plug and solder other end to ground pin on board? I don't know if this makes a difference or not might want to give this a try. Just like putting files into a fortec or Pansat the timing may have to be right with Jkeys. Try hooking up your wires again and as soon as you hit the on/off switch on back of receiver try running you Jkeys again see if that works. I think your right the rolling b75 means you are now a Pansat 2700. I'll have to look at older files in folders to see what other info I can come up with. I can't remember much anymore the grey area above i.s fading away also I know that rolling b75 is not a hard fix either.

[Dish expert]

Did you run wall.exe in background?

[nashnoush]

Thanks for the reply SKYWARD1, yes I do have ground connected to the fortec coming from the jtag ground. The thing with this stb is that I did it long time ago and I still have the pan's 2700 files. I tried them with no luck, also when the free japan came out, I was watching tv with it, then stb shot off and start rolling the b75. Anyhow, I will take your advice and try to time the stb with loader. I'm not without tv however, only because this stb annoys me, since I come from the atmeg era and jtaging the "good old" 2700, and programing the atmeg was a breese.

[Mr Hanky]

Believe the fortec is a serial cable and the b75 2700 is a null cable.Cant remember its been a long time.

I have the same problem with the fortec some time ago. With the B-75 file on it I am not able to load any file via serial cable. I bought a 20 pin J-tag cable and was able to load some jtag files to the receiver, but I did not know how to make a J-tag file with the 2500-LZMA-V211-IKS-1815 bin which is needed to run Iks on the receiver. I seek help and was told it is very easy to do, but I was unable to succeeded. So I gave up, as this was the only way to load any file back to the receiver. If anyone here can make the jtag file with the IKS bin for this receiver you could help many people with this problem.

The fortec only use a straight through serial cable.

Ask someone to jtag there working receiver. I had a receiver once that the 232 port died and jtag was the only way. If someone will give u a copy mention to them to remove their P$ info.
Hopefully someone can help u .

Which program do you use to jtag you box? Is the box back to normal where you can scan channels with it?

The box's flash does not have any P$ info in it. The info for that is all in the PC or router running the client software.

The mods made to let the pansat do IKS are very very simple--in fact so simple that a fortec file could have similar mods done to it pretty easily--it only formats a coolsat4000 type of packet to send out to the PC and reads in the return CW packet with almost no checking of what it is getting. Out going packet has cmd07 packet from stream and info on channel number and PID for the channel and provider ID--that is it.

B75 use GTRomLoader 27.02,From this boot easy to convert to Lzma-boot 1.03, .
Someone may have the B-75 KR -208-2500 to 2700 and then the CS 258t_B_75.
You have to force the download,As soon as the lines appear at front of STB click on the write bin in the loader 1.4
or try to load a channel list using 27.02, then when thge stb is on convert to lzma using lzma boot then any lzma .bin file.
