In this video we're going to be looking at a Deep Sea Generator Control Panel Model DSE5310. The owner bought it from an auction and wants to adjust a setting, but unfortunately it has a pin code set which is unknown.
Come join me while I see if it's possible to figure out the pin code or remove it completely and what other things will I discover!
I'm not an expert, but I do enjoy trying to fix things.

WOW, this takes me back to when I was a programmer. We needed to modify a piece of test equipment that was bought from a company to expand it's capability to include more equipment testing. They refused to hand us the raw code and stated they would reprogram it for $1 million dollars. So two of us took the EPROM(S) out and read them. Not knowing where the program started or stopped addressing wise, we basically had to search the code to see what they did. It took a few weeks, but we broke the code and added our additional code and WALA, we saved so much money and knew exactly how they coded it...and was able to make it do whatever we wanted with it. Thumbs Up!

Certainly will be easy money... and they probably don't even need to do any soldering as it looks like the data lines for the memory chip actually run to that header. They probably have a device that plugs right in and wipes it so no expertise beyond opening the case and plugging something in would be required.

Reminds me of when Gateway wanted $$$ to reset the "forgotten" BIOS password on my laptop. I hadn't actually forgotten it; it was "". That is, it was 0 characters long, as I changed it to that when trying to remove it. But the BIOS doesn't let you continue without typing at least one character, so it was impossible to enter. I ended up finding the backdoor password generator instead. Screw you and your convenient bugs, Gateway!

My landlord bought a 6 KW turbine, it's windy here so it generates about £5000 a year For an install price of £30000 it paid for itself in six years. That's better than the interest rate of the banks! FYI, you cannot get a bank loan for any turbine that has a gearbox.

13:42 easiest approach would be: - blanking - running once to set the configuration data - A. setting up known pin - reading flash - B. setting up known pin - reading flash. Then, after comparing differences between A and B would give you only changes in supposed checksum and pin itself.

@BuyitFixit 3 ай бұрын

Yes, setting I had thought of that but setting up a known pin required hardware that I didn't have, also sometimes blanking an eeprom doesn't always leave a device in a usable state. This was the case with the tractor dashboard I helped someone repair by dumping the eeprom from mine so they had some default values. The video is on here too👍

@kmonyt 3 ай бұрын

My goto approach for these type of things is to use a logic analyzer. Watch the thing live when entering a code. While it could be loaded on bootup, just knowing what addresses the uC accesses allows you to narrow down faster. Same approach I used with a debugger for software key bypasses. You've got great patience to keep pulling/resoldering but I'd be slightly worried about stressing the PCB. I'm sure it's fine, but passively watching the memory reads is just easier! Nice work!

@kmonyt 3 ай бұрын

Sorry, just seeing your other comments now about the log file writing getting in the way of monitoring. Watching for READS from the chip could allow you to separate those log file writes from configuration reads. My preference is to collect all the accesses from startup to pin code entry, and then sort through the data. I use python pandas to read the csv's.

@BuyitFixit 3 ай бұрын

Thanks 👍Great minds think alike! I had thought of that approach too, but when I scoped the i2c pins of the eeprom there constantly data access before even pressing anything. I think this was the MCU writing log files continuously because of the sensors being disconnected, and possibly writes to the display which seem to be on the same bus.

Lovely! I have worked on Caterpillar generator sets with DSE controls on them. They were quite a bit ahead of their time when new. You can even build custom logic to add to the basic functionality and pass logic variables between two DSE controllers. The model we had was equipped with mains and generator synchronization. I worked on a project in Nigeria with two of these connected common bus with the DSE communication bus in place for allowing for them to be used as a two-unit plant. Seeing this brings back memories from my 4.5 months in Nigeria offshore working with some very good people from around the world. Glad you were able to save this one!

In my experience checksum all only required on data that doesn't change (such as calibration data) that would be detrimental if it did therefore you need to be able to detect memory failures. Number of Hours run changes quite frequent and isn't life and death so why bother? Remember, the more tests you have the more chance something going wrong - KIFS.

Back in the day i worked in a factory making fire alarms and there was a certain range of panels you could change the engineer code, and if you forgot it you had to send it back to us. We would then take out the eprom and read the data then using a chart we would look at a certain part of the code which was in hex then convert it to decimal to get the code.

I had to do something similar on my Chevy Avalanche gauge cluster when the memory got corrupted from rapidly power cycling the key while troubleshooting the fuel system. Used gauge clusters were $$$ and the now permanent error message tweaked my OCD. I didn't want to be soldering/desoldering the chip a million times so I soldered a 8-pin DIP socket on the board so I could directly plug the zif socket adapter from the MiniPro straight onto the dash for testing. The data was obfuscated and stored in several different places in memory. I didn't take the time to reverse engineer the obfuscation method, I simply played around with the data until the mileage was correct. I wasn't sure what the exact mileage was so I just rounded up to 150,000 so I knew I wasn't putting less on it than it had. It was a great bit of fun!

@BuyitFixit 4 ай бұрын

Nice, I also did something similar with a tractor dashboard a few video's back.The video is called "helping someone 10,323 miles away" as it was someone that needed a dump from my tractor dashboard who lived in Australia as he had a unit that wouldn't power up due to a corrupt EEProm. I managed to find the mileage in that, and it was stored as binary coded decimal.

Good video, thanks! I think you mentioned it briefly but if you are going to be pulling the EEPROM off the board repeatedly it's worth soldering a switch to the processor's reset line and some flying leads to the programmer. USually only need GND, SCL and SDA. Processor in reset typically puts all its pins in a high impedance state, allowing you to read/write the EEPROM from the programmer

In a way, it goes to show people that their data really isn't as secure as they think, although, you do have to have some knowledge in doing what you do.

You've got a lot more patience than I would have taking that chip on and off so many times, not to mention potential PCB damage. I noticed what looks like two serial resistors on the data line between the CPU and the EEPROM, these are usually fitted so you can back drive the EEPROM when the CPU is off, I would suspect that the EEPROM can be programmed in-situ via the header just below it.

@BuyitFixit 3 ай бұрын

Yes, I noticed them too when I was editing the video, but sometimes it's a lot easier to spot things when watching the video back than when you are actually working on something. The header is for the display, but it seems the i2c lines go there to drive the display too.

First thing I noticed was that the serial data pins from that EEPROM continue on to that debugging header. Companies doing this commercially would likely be using that header. With series resistors between the EEPROM and the processor, you could probably edit the EEPROM live.

@BuyitFixit 4 ай бұрын

Yes, I noticed the i2c pins went to that header too when I was editing. However that isn't a debug header. There is an unpopulated debug header elsewhere. The white header is where the display fits, so I guess that the display is using i2c also.

PCB's are a lot tougher today it seems. When I used to repair boards back in the TTL through hole days, If I desoldered a part more than a couple times, I'd end up with lifted traces.

amazing. I wouldn't have thought it was possible until you did it. I learnt a lot. potentially using the number guessing algorithm sometimes taught in programming 101 classes might have been quicker. blank the top half of the area, if the pin is still set, it's in the bottom half, repeat with blanking half of the bottom half, repeat, repeat, my names on my feet, I'm pete, pete repeat,.

@BuyitFixit 3 ай бұрын

Thanks 👍Yes that approach may have been quicker! It looked like the config data started at 0350 in the EEPROM so blanking the top half, and then the bottom half of that block might have narrowed it down quicker.

If anyone is interested this is pretty much exactly how we OEM engine ecm tuners do our thing, simply put read the eeprom, mess with values on a bench see what changes then create a "map" file for the data, that way we know what bytes to change to change the tuning of the engine in the same vehicle. Gets much trickier with modern vehicles now though, nasty checksums and data signing.

Yes signing and CRC's can be tricky. Sometimes it's easier to get rid of the checks in the code 🙂👍

Thanks 👍The values were just converted from hex to decimal with the calculator. I showed the values on the screen. If you open calculator on windows and change it to programmer mode you can select hex and enter one of the hex values and it will show it in decimal.

DSE has quite neat models, some of them can be networked to cluster of generators. You can set what state the unloaded gensets are, are they running or shutdown standby. Once they’re needed, it will use syncroscope to sync phasing and once they overlap, the main contactor will connect the genset to load (grid). They use these in developing coutries where they don’t have large powerplants.

Interesting, I'm no expert on generator (or anything for that matter 😂😂) but I do like to figure interesting devices out. Thanks for your insight!

On a AUTEL IM608 key programmer, we read an eeprom and dump the file on the Immo side of the machine, the pin code comes up on the bottom corner. Makes key programming easy with the pincode👌

At 15:18 thank you for showing the 'Programmer' option on the calculator. You've no idea how many times I've used a website converter (because I'm lazy) to convert Hex to Dec. Now I have it on my calculator. And I'm an advanced computer/server tech, but never realised it was that simple! I feel like an idiot right now.

Something to be aware of with industrial pin codes. Many times they are something that is on the machine so the factory service tech has a hint. Like the zip ( postal ) code of the maker, some combination of the model number.

Great video - as always. Two more comments from me: The SOIC clip is a bit risky because parts or the whole circuit containing the serial EPROM is powered by the programmer during read/write which could lead to overload. But I think you have this in mind. Another option would be to use a logic analyzer (Salea cheap ones) to record the I2C bus for reengineering.

@BuyitFixit 4 ай бұрын

Thanks 👍Yes that was my thoughts, so it was easier to just remove the chip. I've tried programming them in circuit before (I think it was a Landrover ECU that needed the immobiliser removed) and just ended up removing the chip as I couldn't get it to program in circuit. I had thought about using my LA. I've got one and used it when I was reverse engineering the Milwaukee battery protocol over on Reddit about 9 months ago. I had been thinking about waiting to enter the pin and seeing what addresses it read from the EEProm but because it seemed it was constantly writing logs because of the missing sensors I didn't bother. Thanks again for commenting 🙂

@mrfrenzy. 4 ай бұрын

The danger with using the clip is usually if the MCU powers up and sets the write flag for some reason, which leads you to corrupt data that you need. As long as you have a good dump from the same unit it's not very scary. For some units you can solve it by jumping the reset pin on the MCU so it does not start, also some nice programmers can keep the voltage low enough so the MCU does not start but the EEPROM does.

@e42_channel 4 ай бұрын

@@mrfrenzy. You are right. But in this case it is an i2c EEPROM and all transfers are handled by the bus protocol. And the write protection (WP, pin7) is tied to ground and not switchable, as you can see at 3:25.
