DirecTV serial control app

Where do I adjust the settings....I cannot seem to get the right pin connections for the cable...Does anyone know what they are. I checked out this website which as some nice pictures but I still can't get it to work.

Click on the DTV icon in the upper left and click settings.

If you want I can upload some pics of my cables so you can see exactly how i have mine wired.

[mike1961]

Sure - I'd love to see them. Please look at the bottom picture at the website I posted and look at the RJ22 and tell me if it is correct where when looking at the RJ22 the pins are numbered from 1-4 (as in the picture).

Thanks,
Mike

The DTV Controls gives me a handle for com 1 in the status and then when I try to change channels it keeps saying FA 46 and then Timeout. I'm not sure but I may still have a cable configuration problem.

ok, give me like 15 min and i'll pm ya a link to some pics.

I have checked everything with an ohm meter and continuity to isolate the ground and transmit wires. Also, I read an article stating that all I need really are two conductors, one ground and one transmit from the computer into the receive to the box. I still cannot get the computer to change the channels on the box. Any ideas? This is unbelievably frustrating.

Hrmmm... My pictures don't seem to be coming out well - but i also just realized something I didn't think about before. The placement of the wires really doesn't matter at all in the cable itself - so long it's wired right in the RJ45-DB9 converter.

Basically the way I wired mine was that I have all colors aligned the same in the RJ45 end that I crimped onto the cable, but all 4 of my wires are on the right half of the RJ45 end. Then in the serial converter I wired it so that only 3 wires are actually connected, The top 2 and bottom 1 all the way on the right side (in my case blue, red and orange - but may vary). Orange is going into position 2, Red position 3, and Blue position 5 on the converter end.

I don't think this is really the way most people do it, but hey it worked on the first try...

Lucky you - I can't get it to work after the 10th try. I'm wondering if it is my D10-100 box or something. I have attached a picture that I drew to show how I have the cable wired. I tried it with and without pin 2->2 and I could not get the computer to change the channel. I have gone through this with a multimeter and I have no idea what to do now.

Any ideas?

Hmm I drew up my own lil schematic...

[mike1961]

Your schematic has me very confused. You only have 8 pins (dots) of what should be a 9 pin serial cable. Also I'm not sure where you have pins 1-4 on the RJ22 and RJ45 and how they come out and into the DTV box. I am almost positive my schematic is correct but someone please let me know if I did something wrong and why it might be wrong or perhaps another diagram to show how it should be wired from 9 pin serial to a RJ22.

Thanks,
Mike

I only have 8 pins because that's how many there are in an 8 conductor RJ45 cable... That Picture in the upper right is actually of the inside of the serial converter - sorry should have labeled! It's a picture of where the wire is going to in my setup.

Also I'm not sure where you have pins 1-4 on the RJ22 and RJ45 and how they come out and into the DTV box. I am almost positive my schematic is correct but someone please let me know if I did something wrong and why it might be wrong or perhaps another diagram to show how it should be wired from 9 pin serial to a RJ22.

Basically if you hold the cables side by side the pins will be aligned the same on both ends of the cable - with the exception that the one side of the RJ45 cable is just empty.

[mike1961]

I still don't understand. Do you know if my schematic is correct?

Thanks,
Mike

[mike1961]

DBFresh - do you know which colors you are using that match with which pins? If you could display another diagram showing the details - I'm just trying to figure out why I"m having so many problems getting the computer to change channels on the STB.

Thanks,
Mike

Have you tried reversing the wires in the RJ22? When I was making mine, one of the first google results for "RJ22 pin diagram" (or something similar) had it backwards. That drove me nuts until I tried reversing them out of pure frustration.

I got it to work As it turns out, my prior post with the jpg attachment of my schematic was correct. But, I made one critical error - I was testing the dtv app on my workstation rather than on the server (I should have known better since the dtv app would try and open com ports on my workstation rather than go through the server). It's working great now. Basically, I just got the serial cables and cut them as you recommended and then just crimped a RJ22 jack at the end.

One thing though: because I stripped the serial cable and I'm only using 3 conductors in the RJ22 jack, it's kind of "flimsy." I'm wondering what would be the best way to make it more durable. You see - I can't fit the entire serial cable slightly into the RJ22 connector so I just have the 3 conductors going in and it's flimsy at that end. Maybe I should just get an adapter or something. Any ideas on that (the minor stuff...I can relax now).

Thanks again for all the help - I couldn't have done it without the group we have here:
