RE: GE HealthCare - Logiq 400Hello everybody,
I'm looking for help with the LOGIQ 400, Model 2265944.
Unfortunately I do not receive any support for this device in my country (Germany).
The device remains at power-up with the message at the bottom "CPU MEMORY TEST: SUCCESS", no further reactions can be detected.
In some forums I could read that this cause can be due to a defective timekeeping RAM. I got a new DS1643-150 and replaced it.
However, the system stops at boot up as with the old RAM.
Now I read in the data sheet of Timekeeping RAM that this must be programmed before its use.
So my question: How does the programming of the timekeeping RAM? Can someone help me with a guide or write where I find this?

Thanks for your time

Greetings, If you have a TimeKeeper RAM failure you will see the monitor show no progress after the second bar of the boot-up process. It may also indicate a BBRAM failure. If this is the problem you are seeing then the following is the solution.RE: GE HealthCare - Logiq 400You will need to replace the Timekeeper RAM IC that is located on the CPU. Some units use a RAM IC with a separate battery, most use a RAM with a built in battery. These IC’s are physically taller than a standard memory IC. Usually the TimeKeeper is a Dallas semiconductor IC. It is a socketed IC and is very easily changed. If you remove this IC the system ID and date will have to be reset even if the IC is still good. There is a lithium battery that provides the RAM backup. With age this battery will fail and the system ID and date will be lost. That is indicated by the program not booting past the second bar on the monitor. You can select whatever numbers you would like for the System ID. I recommend that you use the serial number. This will make it easier for anyone else to work on the system. It will also allow you future servicing should you lose the number.
I have attached 5 files. Connecting the Logiq 400 to a laptop computer.doc and Venus Logiq 400 ID time reset without GE contacts.doc are the ones that outline the actual procedure. The Logiq 400 resetting password.doc and Logiq 400 System ID change.doc are for general interest. GE Links.doc provides a link through GE to obtain the service manual if you don't already have it. You will need a PC or laptop running a terminal program. We use HyperTerminal. The older versions of HyperTerminal will not work on Windows 7 or 8. You will require a new release to use these operating systems. The serial cable required is a straight through serial cable. Usually 9 pins on the computer and 25pins on the Logiq. Pin 2 connects to 2 and pin 3 connects to 3. The service manual gives the details regarding the cable and the setup.
Need to reinitialize the BBRAM after replacing the time keeper battery. Need procedure to reset date and time.
