Guys.
I got Datapac 1500 Failed, the detail of fault is that when I press ON button the monitor shown...

COLDSTART TEST REPORT.

Digital Eeprom Test 1->3 Failed

ATTENTION: The internal diagnostics have dected a hardware problem. Save the results of this test report. and contact an IRD representative.

Pressing F1 may allow the instrument to start. However, unreliable operation is likely to occur.

Then I press F1 the Datapac shown....

dataPAC Cold Start 9.8
Waiting to load program
PCMIA Boot: Loading Compressed Image
*************************************************************************************************************************************************************************************************
Then the Datapac1500 shown the logo of program for a quarter of second and the below appeared.

FATAL ERROR !
Requires a dataPAC 1500! 00b044b5
Active task is MAIN_TASK
Critical Level is 0
00b044b9 OS_PEG_S
00b03cc9 OS_PEG_S

Do you have any idea on this regards.

Thanks

Phoo,

One of the chips has went bad. You will have to have it repaired.

Dave

Ouch!

The cost for repair around 40% of new Enpac1200's price......Does anyone know where I can buy the chips, I want to make a trial to replace the chips...may be it can work, if not, Could it use as an aquarium ?

I'm not familiar with the Datapac circuitry, however, I suspect that the EEPROM may be one of the Dallas battery-backed parts with either an external coin cell battery or an integral battery. The ones with an integral battery have around a 10 year life but it can vary pretty widely. These are frequently used to store setup parameters and route information.

You might look for either a coin cell or a large chip from DALLAS. If you see a Dallas part, check the part number at www.maxim-ic.com to determine if it has an integral battery. If there is such a chip, replacing it MAY solve the problem....if the software reloads the missing information. If there is such a chip, it may be in a socket in which case it can be replaced with some care. If it's not socketed, it would have to be de-soldered which is not a project for someone not experienced in electronics.

Good luck!

I attached the picture that shown Dallas chip.At the left bottom of picture, the green one, is it call coin cell?
Now, I going to but the new Dallas chip to replace to the old one.

Actually, I am mechanic, whatever....just 28-PIN SOIC

Thanks

I know nothing about circuitry or repairs, but I own stock in Maxim and think you should buy one of their chips

Phoo must have bought a chip from Maxim-it is up $1.20. Thanks for the help

Danny, I love MAxim parts and use a lot of them. I'd use even more if, after I've found the perfect part and started my design using it, that there wasn't an 8 week lead time if I want to buy 10,000 at a time and even longer in managable quantities. Could you talk to somebody about that? <g>

Phoo, I don't believe the clock chip is part of the problem, although they are sometimes used to provide a backup power supply for memory chips. The green item appears to be a large electrolytic capacitor. Probably not related to the problem either.

It looks like this unit uses non-volatile memory which doesn't depend on a battery to maintain memory. Without being familiar with the circuit, I can't be of much more help.

I believe there are some companies doing data collector repairs that don't require the yearly extortio...er...I mean maintenance.... fees that some manufactures charge.

Jon,

Taken care of. Next time just drop my name. My 150 shares really gets attention

Danny

Phoo,
