How to Emulation Emulation How Too For D and B What Im presenting is a living document. Receiver, Dish of course, emulator interface, emulator programer, software, Digital Locks, and a Jtag Reader/writer. Well emulation can do almost anything a card can do without worrying about looping or locking it. About the only things that dont seem to work well is blockers on these setups. But with a bin, you can modify it to your hearts content without the risks of damaging the card! Now you can get a G2 card or your own card with it unlocked for the same price for the setup to match. Computer and Software Depending on the speed of the computer depends on how many irds and what software to use. The receivers with the 512K flash memories, for example the 2700,2800 and 3700 are examples of small flash memories. Id say the easiest software is winvu though at this time I would not run it now on Dish.
Though some use a simple jtag reader be aware that the leads need to be short and plugged into the back of the ird. The longer the cable with out a external power supply the greater chance for error. Use Dave2s excellent program jkeys 201 for reading and writing to the tsop and eeprom. Once you have your jtag reader and Ird you will need the boxkeys off your ird. See Jkeys instructions on getting them and You will need your ird and a Cam. That is what I did, it has to fit a certain pattern but the number is made up. Emulator Interfaces Emulator interface, There are basically 2 emulator interfaces. What you would do is use a Seasoned interface Direct TV emulator with a serial card with the crystal changed on it. First is: Modified Serial Card If you get the Winvu program in the readme file it gives you the formula for changing the original crystal to the new value. Recent events with the newer winvus made what use to work before to not work anymore. Which led to chasing the crystal frequency that will work with certain irds. I have seen by dssbat show a setup to run pad 3 from the ird to a daughterboard attached to serial card. Since winvu 2008 came out Ive watched what could be done to make it work. What the resets seen in the display are, its a sync issue between the ird and computer. In the avr setups for emulation, they all have a connection to pin 3 on the iso card. Though I have seen an elaborate setup that used it for a modified serial card, mounting a daughterboard on the serial card to sync the ird to the serial card. Another thing all the irds are essentially the same frequency baud 140,600 but within a model number the irds seem to be slightly different.
He lists all of them that he has tested so far other than the 6000 as the same. There are general class differences, meaning around the 140,600k baud that is coming off the ird some of them are a bit lower and others are a bit higher. A side note the 6000 runs at around 128K With that all said it makes it difficult to tune in and find the frequency and crystal combo to tune in and not get the resets on some irds. I know of another guy eduardokk over at IM who really went deep into getting the modified serial cards to work. What I found is that the slight variances in frequency are corrected by having the sync on the atmel chips. It makes it easier than chasing the frequency of the irds and the modified serial cards. I made these general comments at the beginning of my post on the max232/2313 hybrid emulator. Ive got general ideas of what crystals work and what doesnt on most of the irds. It just if it doesnt and you dont have a right crystal in the serial card, you have to keep changing it. But the cost to buy the serial card, buy the parts and make the cable. But I did not want to put in that time and effort and money into it, that was me. So just be aware of those issues when using the modified serial card. Also of note the latests java and CEMU are suposed to support the modified serial card. I know with CEMU you might have to start and stop the program to get it start. So realize there are other options out there for the modified serial cards. I have shifted to the 232/2313 setup and all those software programs seem to work fine with it. You have an atmel chip hooked up to the ird and you use a standard serial port interface. I have posted an internal one, which I believe is the best of both worlds and I give explanations of it.
The atmel chips are designed for 5 to 0 volts input where the communications is put. The computer puts out -10vdc to 10vdc for standard rs232 communications. Thats why I warn everybody that has an avr at least put some protection on that avr. Though I think that is a crude rs232 interface its better than nothing, but its not an rs232 interface. Of course unless its setup to run as emulator external with the proper protection. I dont think the zeners are the proper protection, but its better than nothing. I cant recommend any avrs to buy, never did buy one for emulation and never will. If I buy an avr it will be to use it as one was originally intended. It offers the protection rs232 interface and a chip that runs the frequency conversion program. The other nice thing with the atmel is it is synced to the ird so the hassles of finding the right speed go out the window. Im starting to see some commercial versions of this setup come out, that is external. So for you guys that dont want to build it internally can get the same advantages. I go over building the internal with pictures in the walk through. Atmel programmer You also need just a simple programmer for the atmel because the circuit to program the atmel on board would have made it big for and internal unit. Digital Lock optional At this time I cant recomend any digital locks.
