Program timekeeping RAM

Hello 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?

My e-mail: m.prescher@online.de

Thanks for your time

I do not know this specific system, however done the same for other equipment.

you need a working RAM module(from a working unit) and a programmer to copy the working RAM into the new one.

Be aware that calibrations are stored here, even serial number might be there.

If serial is there than you need to do some hex editing with checksum calculation etc.
