Help Needed Restreaming 2700

[Joe_4090]

Hi Everyone:

I know this has probably been posted before....
but I am a bit rushed and too lazy to dig thru
all the posts to find it. :)

Am trying to restore a 2700 IRD with 2800 firm-
ware. I hooked up J-Tag and erased SA5 as per
instructions. Hooked up to sat. dish and plugged
in but so far doesn't appear to be taking the re-
streaming. I haven't noticed the light blinking.
I tried turning it and tv on with card in and still
nothing but ch. 100 & 101

Could someone talk me thru the steps please?
should IRD be turned on or off....card in or out...etc?

Thanks!

Disregard please.
I repeated the entire procedure and
it restreamed immediately this time.
Back up and running.

all it took was a little patience
It sometimes takes a few more minutes than usuall to restream one

It's like a Disney movie-always a good ending! May I ask what you used to JTAG your 2700? I haven't gone through this process yet and feel the hardware is just as important as the software we use. Was there a hole for the connections? Where did you find the pin out to know the proper soldering pin numbers at both ends of your cable? Thanks

Hello Sleasy Rider:

Let's see if I can answer your questions.

J-Tagging the 2700 was done with a buffered J-Tag
purchased from Mili's online store.

Yes the 2700 does have a J-tag port underneath.
Not all IRDs have them. Some must either have a
port cut out or be disassembled in order to be
J-Tagged.

Mili's main page at www.dssmili.com has a lot of
useful info. Check the menu on the left and be
sure to read the 'how to' instructions and the
'getting started' page. There you will find links
to all aspects of J-tagging.

The wire/pin sequence on a J-tag purchased from
Mili is as follows:
Holding the wires in one hand, turn them so that
the red wire is over to the right....from left to right:
First wire =TMS
Second wire = TCK
Third wire =TDI
Fourth wire = TDO
Fifth (Red) wire = TRST
Black wire with alligator clip = ground

Now turn the 2700 upside down. The J-Tag port
is located near the front of the unit. You will see
one row of 7 solder pads and a long solder strip.
Turn the unit so that the long strip is beneath the
7 pads...not above them. The pin sequence is
as follows on the 7 pads left to right.

Wire one (TMS) on pad 2
Wire two (TCk) on pad 3
Wire three (TDI) on pad 4
Wire four (TDO) on pad 5
Wire five (red) TRST on pad 6

Use fresh batteries in the J-Tag. Connect the ground
wire to a good ground....on the IRD case. Don't forget
to plug in the IRD before attempting to read J-tag.

Hope this helped.

Yes thanks- I think what I want to see is the physical layout of the JTAG IRD PADS like the following site.
http://www.dishnewbies.com/jtag.shtml
I have see help sites that count PAD numbers from the right and 6 becomes 2 in the attached tables (same help location) and us newbies get confused real quick. With the site above and your information I think I will survive not blowing up my IRD. The purchase of the JTAG will identify the methodology and how you arrange the correct configuration of the Pogo pins on the particular IRD. Thanks again!

Yes, the pin/pad sequence will vary with different IRDs
The J-tag sold by Mili comes with a plastic connector
which the pins fit into...and fits into the J-tag port...
and yes, the pins can be rearranged in the connector
in accordance to the pin/pad sequence for a particular IRD.
If an IRD has no j-tag port, then you may have to devise
a permanent external connection. Some testers utilize
the IRDs phone jack...connect the wires from it to the
J-tag pads. There are a number of ways to make a
'quick-connect' for the j-tag. You might want to do
some reading on the forums to learn more about them.
Here is a link which has a chart which shows the pin
sequence for some IRDs. http://www.dssmili.com/whole_frame.html
If you click some of the links at the top of that page....you will
find a more detailed chart.

Thanks-I also realize that TSOP information is retrieved and sent to the IRD using the JTAG method-Are there any advantages of purchasing one JTAG over another if reflashing the TSOP is going to be a frequent event? Or is my understand of retrieving/flashing the whole eeprom file all wet?

[Joe_4090]

As for J-tags....I am not familiar with every type. I can only say
that a buffered one is recommended. Less likely to overload the
printer port.

To repair an ECM....it is usually only necessary to erase one
sector of the TSOP....not the entire TSOP. The entire TSOP
would only need restoring in the event of an accidental erasure
of the wrong sector or something of that nature. Of course
you would want to back up a copy of the TSOP when you
J-tag an IRD for the first time....just in case. The sector erase
can be done with j-tag without having to access the saved TSOP.
Many testers have opted to install digital locks on their IRDs.
These will most of the time eliminate the need for J-tagging in
the event of an ECM.
Again, I recommend reading the 'getting started' and the 'J-tag
how-to' sections at www.dssmili.com
