Dishpro diseqc commands with twinhan 1027 card

[CausticSoda]

I have a Twinhan 1027 card and a dispro twin head LNB. I have not been successful at getting DVBDream to change LNB's. It usually just wants to stay on one or the other and wont change under program control. I am sending custom diseqc commands and everything and the thing wont budge.

What is the proper diseqc codes to send to the dishpro twin to get it to switch from one sat to the other? I've tried sending a diseqc RESET command first, sending the switch command multiple times in the same command string, using device address 00 (all devices) and it simply ignores everything I send it. I am using the latest drivers from Twinhan.

I can get it to almost work with MyTheater, but it only works if another STB is plugged into the other port on the LNB. The other STB works just fine.

Any advice would be appreciated.

you might not have much luck for Diseqc with the Twinhan models other than 1020 and 1030 (which are the only twinhan models in DD's supported/tested devices list)

I've been researching Dishpro and diseqc since my first post. The fact is that there doesn't seem to be much information out there about it. There is a diseqc spec that I have, but nothing for dishpro.

The Twinhan and all other tuners have to use diseqc commands to in order to set the local oscillator frequency of the LNB. So there must be an existing working diseqc interface. I was also able to get a response from the reset and Power-On commands.

I'm not positive what MyTheater is doing differently, but they are definitely working better - just not 100% correctly. I read a post on another forum that said that the programmer had to write a special routine to make it work. They said something to the effect that the BDA spec didn't support diseqc commands.

So the bottom line is that the disceqc commands that are sent to the dishpro are non-standard. Another source suggested that they only listen when the voltage is 12V.

Anyhow, I know another person with the same problem. This was only discovered AFTER I spent two hours bragging about how much better DvbDream is over the others.

After doing some more experimenting it looks like DVBDream is simply ignoring the diseqc commands all together. Setting the LOF frequencies to improper values doesn't make the Dishpro malfunction so apparently it isn't receiving any diseqc commands.

Also, I connected the Dishpro Twin ports A and B to a Viewsat Diseqc switch. On mytheater, it switched between them flawlessly. On DD, it didn't do anything. It merely stayed with the defaults.

Anyhow, this is a showstopper for me if I can't use the switches and motors. I don't want to have to install a manual A/B switch out there.

Does anybody know what needs to be done to fix this so that DD will work with the Twinhan 1027 and Diseqc switches?

It is not the dish pro its the dvb card. I had a dish pro with a digistar dvb card and dd would not swoitch the lnb. I upgraded to the best dvb card there is (skywalker-1) and everything works great. You can get your setup working in other dvb app but you must setup the app to use port 11 for the dish pro switch. You can try using Raw Diseqc in dd

E0 11 38 F2 sat 1
E0 11 38 F6 sat 2

That will set the port to 11 but may not work but its worth a try.

Thanks Shep.

I agree that the Skywalker is definitely the best from what I've heard, but unfortunately, its beyond my price range. The Twinhan DVB-S cards are rapidly becoming a laughing stock of tuner cards. I did try those Diseqc codes and there was no effect. From what I can tell, there is no Diseqc output from the card regardless of what you put in the fields.

I really don't think the BDA driver is working correctly. However, I think it works just fine with Mytheater. (Ok, maybe not just fine, but better anyway). Still, I think the BDA driver is the culprit.

I really hate this because the DvbDream program is way ahead of everything else out there. I really want to give it my best shot before being forced to use ProgDvb or Mytheater. As far as I can tell, the Diseqc issue is the only major flaw in DD.

Hopefully someone can shed some light on this diseqc issue.

I'm in the same boat as you... I have a Twinhan 1027 and can't get diseqc working... Some of the Twinhan cards in the supported devices list are legacy cards now. The 1020 is old and isn't even made anymore. Sooner or later the new cards such as the 1027 will need to be supported.

Hopefully the 1027 will be supported soon.

This doesn't help much, but I'm successfully using a DP twin (and DP dual) through a DP34 switch, with a Twinhan 1025. This model is the precursor to your 1027, so I think it is very similar.

I'm using the Twinhan BDA driver version 1.2.3.8 for my card, and the latest DD 1.4. I have the switch (and LNBs) powered from 3 Dish Network receivers, so my Twinhan card isn't trying to power all this gear by itself. Since none of my receivers are cabled up directly to the DP twin, it should be running in it's default configuration, which is to put out 110 on one coax and 119 on another. In other words, the switch in my twin is not being used at all; switching is done exclusively by the DP34.

Perhaps your twin is marginally defective, or not getting enough power, or not getting switched out of it's default configuration.

[genericdude]

Yeah. I'm starting to see the problem more clearly.... The 1020, 1025 etc... are all older cards... Since BDA spec doesn't including any kind of switching, switching code tricks must be figured out on a card by card basis (even from the same manufacturer). Rel has probably had the opportunity to work on many of the older cards (or better examples to work from). Anyways, the bottom line is if we want to get Diseqc working on the 1027, we need to pitch in some money to buy rel a Twinhan 1027.

I'm willing to kick in $10 or $15 bucks. Anyone else?

It would seem that Generic Dude and TheKrell could not both be correct - either the Twinhan bda drivers cause switching to work or they are not capable of it or, is DVB Dream is doing something to make up for the lack of capability of the driver? Or is it only the ability to switch the DP Twin LNB (as opposed to the DP34 switch) which is lacking in the bda driver? It would be great to get some real clarity on what the real problem is with Dishpro equipment, perhaps from the coder.

[bigdawgte]

I tried to scan in the 110 satellite (I had already scanned 119), and something interesting. I find that dvbDream is able to switch just fine between 119 and 110, hooked directly to the DishPro twin lnb. So if it can switch the lnb, without aid of another receiver (power injected), why does it have so much trouble switching DP34 with a D* receiver connected?

[TheKrell]

why does it have so much trouble switching DP34 with a D* receiver connected?

Mine is working reliably. I've even cobbled together a custom switch for my new 625... I cannibalized a DishPro Plus twin for it's switch, which is now on the DP34 passthrough ports. Now my DP34 is only powered by a single Dish 501 and my trusty old Twinhan 1025. Both tuners of the 625 are connected (through a separator) to a single cable from the DPP twin's switch. Amazingly enough, everything still works as advertised.

Would you like a short clip from the NASA channel (119), Dish Home (100), and 9902 (61.5) as proof?

[bigdawgte]

Err...Proof? No, I am glad that you have managed to get your setup to work: tu es muy macho. What we are all here interested in in is HOW you did it...
E.g., what are all of your DiSeqc settings, please?

I think he is talking about the 1025 and not the 1027. The two are different animals. The 1027 is very resistant to working, however, it is possible because it works flawlessly in MyTheater.
