I have been thinking about building one of N0QBY's FTA projects. The DiSEqC code reader.  
Code:
http://www.ringolake.com/pic_proj/satellite/sat_projects.html
It displays DiSEqC commands sent by the receiver to the switches and motor controllers. I understand that the new DiSEqC 2.x protocol is a 2 way communication between the DiSEqC device and the receiver. So do you think the code reader will see the answer back from the 2.x DiSEqC device? That would enable you to make some use of the new technology without having a 2.x compatible receiver.

I have the components gathered up to build the device and have begun to lay it out. I'll post some pics when I get some more done.

Hey Fearless,

Would love to see this and know how it works for you if you have built it.


 Cool

I have built both of N0QBH's Polar rotor control projects and liked how those turned out and this one was no exception. I have learned a lot about how my system works with this device. You can check switches to see if they pass calls and which ports they do. I was thinking the positioner was sometimes not hearing the first DiSEqC call and the receiver had to repeat itself. But instead I found the receiver doesn't always issue the call immediately. I found calls I didn't know existed until I built this. I'm just finding out all the things I can check out with this. Here all along I thought it to be more of a novelty than a tool. Definitely a useful tool  smiley
I built two of these. One with a 2x16 display and one with a 4x20 display. I gave the 4x20 away as a gift to Brian Gohl.  There is a different firmware for the 4x20 unit because of the display addressing. Many thanks to N0QBH for all his help and assistance on these projects!

I was very surprised and happy to receive this wonderful Christmas gift! Fearless did a great job and very well constructed. Looking at it, one would almost think that it came off the store shelf!

Works very well and makes testing so much easier! I previously would have to have the device that I was testing next to a PC and use a sound card to capture the DiSEqC strings. Now I can test for DiSEqC commands outside at the installed dish and on the other side of motors and switches!

Thank you for the great project and gift!!! What are you building next? :D

That is very impressive! Super quality work Fearless, i agree with Brian it looks almost store bought. I can see how this could be a useful tool. Now you got me thinking i may have to build 1 for myself. I do think i will have a little extra time on my hands in the next month or two. Maybe this will be one of my projects.

Thank you Fearless for the pictures of your build, and the link to the article with N0QBY's's project. And thank you to N0QBY's for showing folks to build one of these.

I am always just amazed at the things people in this hobby can create.

Couple of questions -

Pic 1 showing the 9v battery attached to the F Connector - is this just to show the unit powered externally? Or always powered this way?

Pic 2 shows 2 coax cables, i am assuming 1 from the receiver (powering the unit) and the other from the positioner?

And the RS232, this is used to connect to a PC if you want to see the output there? And also for upgrading firmware?

Last question - what would you think the parts cost estimate would be to build one of these, assuming you had none of the materials to start with?

Thanks in advance.

First, I typo'd the authors name. If you could fix it maybe? It is N0QBH not N0QBY.
I used the 9v for power test, setting the contrast on the display and checking the switch. The unit is powered through the coax. You can use one cable and a "T" fitting or two cables I/O. Whatever best suits the situation you have  grin

The Serial connecter is TTY data out only. You can log the calls with a computer. N0QBH used Hyper Terminal. I'm Using PuTTY
Hard to estimate parts. Most of the stuff is scrounged up. Salvaged components and repurposed parts. The 2x16 display I bought for $12 but the blue 4x20 I put in the ASC1 cost $6 free ship from china. The PIC is $1.50. And the PIC needs to be programmed. The cases were given to me as junk stuff.

If you buy your PICS from Digi-key, just email them the HEX file, and they'll burn them for you for FREE!

That way you don't need to buy or build a programmer.

I checked into that. They will program PICs, but not free. It's a $50 setup fee and price per chip programming starts at $.25 ea min 200 pieces. This was quoted on the PIC 16F628A used in this project
I use a Pickit2 programmer
