Radionics D7212B1 Panel Help

Inline...

| I see 5200 programmers on sale on ebay all the time. What "product handlers" | would I need to fully program the board? The product handler for the 7212 panel...I cant remember if the 1255 needs one too, I can't remember if you needed t he 5200 to program in the alpha in the 1255s or not. I still have a few of them somewhere.

| Are there no other tools to program these boards? RAM IV (remote programming program & modem & special dongle) or 5200

| Is the command set to the board documented anywhere? Low level stuff? I doubt it. Programming manual you may find somewhere, maybe Jim Rojas has one. I think I dumped the ones I had, I'll take a look later. They're not available from Radionics, looks like when Bosch re-did the website they dumped a lot of the old stuff.

| Is it normal that an uninitialized board would not talk to a D1255 | controller? If I get it talking to the controller, can I program everything | from it? Yes, normal. The panel needs to know about the keypads being there.

| | While I'm firing off questions, I also purchased a few OCTPOPITS D8128A. The | documentation is contradictory regarding which versions of these A,B,C, or D | are compatible with this panel. What were the differences between these | revisions?

Honestly, I don't remember...I had always found the Popits, Octopopits confusing and still have nightmares about them so I try to not remember...sorry.

| | Sorry for all the questions. I'm eager to get this thing working.

Good luck on the adventure. It'll be interesting to see if you do.

I recently purchased a Radionics D7212B1 panel from my local surplus store in the hopes of building a simple, non-monitored alarm for my house. The board is dated 9743 and numbered 7212. The EPROM on the board is labeled (C) Radionics 1995, D7212B1 U4, 26-06962-0316. The Lithium back up battery was shot (

Oh god walk away from it please........

Not the panel, I'm talking about the person who owns the panel

I love it when they say "I'm handy with a soldering iron..", big whoop!

Not gong to do jack on IC circuitry and it won't get the panel programmed, it just means they are handy with a soldering iron

I just pulled mine up, it's 119 pages :)

I can remote download your panel and see what is wrong with it.

Jim Rojas

Crash,

Thanks for the reply. I'm pretty handy with a soldering iron so I think the board hardware is OK. Really depends on Radionics' software design as to if any "magic" needs to be retained in the RAM to make things work. If so, I'm sure it was blown away years ago.

So I understand I must have a 5200 programmer to initialize the board? I see 5200 programmers on sale on ebay all the time. What "product handlers" would I need to fully program the board? Are there no other tools to program these boards? Is the command set to the board documented anywhere? Is it normal that an uninitialized board would not talk to a D1255 controller? If I get it talking to the controller, can I program everything from it?

While I'm firing off questions, I also purchased a few OCTPOPITS D8128A. The documentation is contradictory regarding which versions of these A,B,C, or D are compatible with this panel. What were the differences between these revisions?

Sorry for all the questions. I'm eager to get this thing working.

Thanks again for any help.

It's not that bad... :)

Jim Rojas

Yes, it does give the term "over engineered" a new meaning...

Jim Rojas

Bad news...you're screwed. First of all, the lithium battery was dead. That means the panel has lost its program, and you will have to send it back to the factory for reprogramming. Even if you had a 5200 programmer, you'd still be screwed. The panel contains a "datalock" code, which prevents one Radionics dealer from programming another dealer's panel, and now that your panel has a dead lithium battery, no one except the factory can reprogram your panel. (Maybe Jim Rojas knows how to fix this, but ordinary Radionics/Bosch dealers do not.) A 5200 programmer will show a datalock violation, and RAM IV software won't be able to connect, either.

I'm a longtime Radionics/Bosch dealer, so I know what I'm talking about. I've had panels I purchased lose their memory due to that damn lithium battery, and had to send them back to the factory for repair. I would cheerfully strangle the life out of the engineer that designed these goddamn things.

Rule 1: do not ever buy a used Radionics/Bosch panel unless you are sure the seller has restored the panel to factory defaults, and that you have a

Thats probably the main lock the 6 digit one. Then there's a 4 digit remote programming lock.

Nobody says you have to sign a contract for an alarm system the problem here is you have an ancient junk panel that in the end will still be worthless no matter how much you work on it. My suggestion is to get a decent and fairly new panel and work on that. Plenty of those on Ebay

Mark,

I appreciate your concern over my abilities to work with electroincs. I can assure that I am not in over my head. I bought the older version of the board just because it has a socketed EPROM that I could extract the code. My intention is to use the Radionics code if I can. Otherwise I am fully prepared, and capable, to write an entirely new program for this board. And yes, I am that good. I currently have a good protion of the original Radinonics code decomplied and I am using a logic analyzer to track the operation of the microprocessor in areas where the code is not clear to me, yet. I have the key circuits mapped out on the board and I am adding to my knowledge daily. For example, I already know how to unlock this panel by running a program to change the password in RAM. May not be the best way to do it, but it can be done. I can also monitor and inject communication signals into the peripheral bus using my PC.

I expect your perspective is different from mine. For me, this is a fun project to see how something works, down to the bits, bytes, volts and ohms. If I get a useful alarm system at the end of it all, good for me. If I don't, I learned one heck of a lot and my next design in my "real job" may be just that much better. As you suggest, if I ONLY wanted an alarm system, this is NOT the way to go. I agree. Trouble is, I don't learn that much by signing a contract for an alarm system around the kitchen table.

Perhaps, if you are interested, you could assist me in my investigation. Do you have any detailed knowledge on these types of boards beyond what is written in the installation/maintainance/programming manuals? Do you know the various commands and command formats that are actually sent down the wire from the modem and/or used on the peripherial device serial bus? Do you have schematics? Repair manuals? Source code ; ) ?

Thanks for your concern and assistance.

Bob

Badenov,

Thanks for the information. I am in contact with Jim Rojas and were going to give it a try.

I appreciate the detailed information on the lock-out mechanisms on these boards. One of the problems I have is understanding what is "normal" behavior and what is the result of losing the lithium battery. Can you give more info on the lockouts and passwords that are used? I am currenly decompling the EPROM program and I have located at least one password in RAM along with the default "000000" in ROM. How many levels and types of passwords are used in these things?

Thanks for all your help.

Bob

There are two different types of passwords, the "datalock" code and the "RAM Passcode." The datalock code was developed at the request of some larger alarm companies, who were unhappy that smaller Radionics dealers could take over their accounts by reprogramming them. Datalock is intended to prevent one dealer from programming another dealer's panels.

The datalock code is entered as a decimal value between 0 and 65535. It is selected by the installing company, and is typically the same for all that company's systems. Both the 5200 programmer and the remote programming software check the datalock code before allowing any panel programming. The factory default datalock code is 12345. The first time a programmer is connected to the panel, this code is automatically changed to the primary datalock code that the dealer selected.

The programmer can check up to 50 additional datalock codes besides the primary and the default codes. This allows one company to service another company's accounts without manually changing the datalock code in every panel. I do not know if the limitation of 50 codes is enforced by the programmer or by the panel. It may be possible to try every datalock code in sequence, or it may be necessary to do them in blocks of 50.

When the panel's lithium battery dies (and no other power is connected), the datalock code gets wiped out. Since it is neither the correct value nor the factory default value, the programmer will not communicate with the panel. Presumably this is done to prevent dealers from circumventing the datalock protection by removing the lithium battery. So, the solution is to force-feed a datalock code of 12345 to the panel, only that's beyond my abilities.

The datalock code is the only lock code that is checked when the 5200 programmer is used. However, when the remote programming software (called RPS or RAM) is used, the panel also requires a "RAM Passcode." This consists of six hex digits. Typically, it is different for each panel. It's fully programmable by the dealer. Its purpose is hacker prevention, rather than dealer lockout.

If you do decide to go shopping for a 5200 programmer, you should expect it to be secured by a password. I'm sure that won't pose much of a problem for someone with your abilities, though. The password is set by the user, and is only contained in the programmer, not the panel.

Good luck with your project. I hope you'll feel like sharing the results of your research with the rest of us.

At least it was better than the 7112 - which nearly killed me business-wise...that was a piece of crap.

Even if you get it to work it will never be a good alarm system

Badenov,

Thanks for the detailed information on the Datalock code. It will be useful as I investigate the panel. I like these puzzels and I might end up with a good alarm system when I'm finish, all the better.

If I come to some useful results I'll surely inform you.
