ok, i finish doing the 25xtreme.
I was told to connect serial port from my computer to tivo ird.

ONE problem, no serial port on the back of the ird. There is a hole that said serial but is there an adapter that convert the serial cable to that type of plug?

any other suggestion or link to help would be grateful.

oh, in the extreme-emu.com guide, it doesn't say anything about doing bash prompt or touch stuff. Is that necessary?

thanks,
joe vu

Nice post alpha-pup. And people say posters here are not helpful...

The best way to find the answer is to search on 'serial cable' using the search tool on the board. You are correct about the cable, it is a custom cable that needs to be made or purchased.

There are a couple ways to make the cable, either buy pre-made parts from Tivo and Radio Shack and just hook it together, or make it yourself with much cheaper parts (and a soldering gun) from Radio Shack. Or, if neither of these seems workable, I sell them to custom lengh if you don't want to do either of these things. PM me for details if you want a quote...

Yeah if your motivation is to sell him something then your bound to help him out at first.

Don't even do that, just RTFM and you will see that it barely costs $12 to go down to rat shack, buy 2 cables, and splice them. I know a 12 year old that made his own cable. Just READ damnit.

AlphaWolf; do u mean this setup?

If you buy a serial cable with a male & female db 9 connector at rat shack (or an old one lieing around the house) and get a double ended 1/8 stereo plug cable (or an old one from a sepaker set from the computer), you have everything you need. To put this in lamens terms so anyone can understand.

Cut each cord in half. Set aside the female DB9 from the serial cable , you will be using the male end.

Take the DB9 male connector and Strip the wires. You only need 3 Red, Yellow and Black.

Strip the wires of the stereo plug. The colors will be Red White and bare or exposed stranded wiring. Twist the stranded unshielded wire to make it a more firm wire.

This is how they are wired up:

Serial Cable ----------------Stereo Plug cable

Red-----------------------------------White
Yellow--------------------------------Bare wire
White---------------------------------Red

Many people ask how to get a BASH prompt from their TiVo. After the explanations come, usually the next question is "I have no serial port!" or "Where do I get a cable?".


Serial Cable 101

The Serial port is a 1/8" phone jack on the back of your unit mysteriously labled "SERIAL". ;) There is also an infrared blaster port right next to it.

You can buy a Factory cable from TiVo (http://store.tivo.com/Detail.bok/9dd0ee6771358822561010160285307?&category=Accessories&start=9&total=24&no=37), or make your own. Keep in mind that a Factory Cable is wired to connect to an IRD...not another serial port, and will require a Null Modem Adapter - Cat# 26-264 (http://www.radioshack.com/searchsku.asp?find=26-264) to work correctly. Since you have to go to Radio Shack for this anyway, you might as well make your own...it's cheaper, you can make your own length, and you can have one finished tonight!

This is what you will need from your local Radio Shack:

9-Position Female Solder D-Sub Connector - Cat# 276-1538 (http://www.radioshack.com/searchsku.asp?find=276-1538)
6ft Shielded Extension Cable (1/8") - Cat# 42-2387 (http://www.radioshack.com/searchsku.asp?find=42-2387)
9-Position D-Sub Hood - Cat# 276-1539 (Optional) (http://www.radioshack.com/searchsku.asp?find=276-1539)

Cut one end off the cable and solder the following:

Red Wire (Tip) -> Pin2
Black Wire (Ring) -> Pin3
Silver Wire (Sleeve) -> Pin5

For a more advanced cable of any length, purchase a Stereo 1/8" Phone Plug - Cat# 910-0763 (http://www.radioshack.com/searchsku.asp?find=910-0763) instead of the audio cable, and use CAT5 Cable - Cat# 910-1603 (http://www.radioshack.com/searchsku.asp?find=910-1603). Place the transmit (Pin2/Tip) on one pair, and the recieve (Pin3/Ring) on another pair. Connect the ground (Pin5/Sleeve) to both the other connections of the pair.

Example:

Pin2 -> Orange Cable ->Tip of plug
Pin3 -> Blue Cable ->Ring of plug
Pin5 -> Orange/White AND Blue/White ->Sleeve of plug

Then you are good to go!

Classic reply again Alphawolf...

I offered up him how to find it, and 2 ways to make it. I also said that I could make one if he wanted one. BTW, the spice method is not recommended, unless you have a voltage meter, since there seems to be no standard for the serial cables at Rat Shack. But you are far to superior to the rest of us to think about that.

RTFM is not even a reasonable response, as there is no 'manual' on this. BUT, there is a search tool that works very well, as I indicated.

Time for you to go to the back of the pack....

1) read who wrote that recommendation

2) a multimeter costs a lot less than a soldering kit, as well as being a lot easier to use (actualy you don't even need a multimeter, if you wanna go el cheapo, I know somebody who uses one of those 9 volt duracell battery testers)

3) the 25xtreme documentation gives plenty of direction for the serial cable

4) F-O

What about the ones that come with the standalone tivos to control the recievers. Will those work?

They work with a null-modem adapter.

(sigh) It's all in my "Serial Cable 101" post above. Thats the Factory cable I spoke of...

Here...I will post it again so you dont have to scroll up. ;)

Pointfreak,

One quick question that wasnt completely clear to me. On the DB9 end of the cable I would attach the orange to pin2, the blue to pin 3 and both the Orange/white and the orange/blue to Pin 5. Im just having a hard time visualizing this.

"For a more advanced cable of any length, purchase a Stereo 1/8" Phone Plug - Cat# 910-0763 (http://www.radioshack.com/searchsku.asp?find=910-0763) instead of the audio cable, and use CAT5 Cable - Cat# 910-1603 (http://www.radioshack.com/searchsku.asp?find=910-1603). Place the transmit (Pin2/Tip) on one pair, and the recieve (Pin3/Ring) on another pair. Connect the ground (Pin5/Sleeve) to both the other connections of the pair.

Pin2 -> Orange Cable ->Tip of plug
Pin3 -> Blue Cable ->Ring of plug
Pin5 -> Orange/White AND Blue/White ->Sleeve of plug"'
