Beckman Coulter Biomek 2000: workstation cannot communicate with the biomek

We bought a used Biomek 2000, but cannot even get it to communicate with the software.

Any guidance would be much appreciated.

The situation is basically the same as Joey's ( It powers on, beeps on power on, the fans turn, the green light on the front is on. We use a WinXP notebook with a USB to serial controller (we also tried with a normal serial cable, as the notebook has a serial port). When we start the software called "Workstation Server", we see that some information is transmitted to the Biomek, but nothing is received (we see this because the USB to serial adapter has little Transmit/Receive lights which flash on data transmission). So the software connection status always remains red and at 0%. We experimented with different baud rates (does it even matter?).


Some of the questions we have:

1. We somehow got hold of a Bioworks software suite Version 3.1a and 3.1b (Y2K update I believe). Does anyone have an older or a newer Version and would be willing to send it to us?

2. Is there a way to do something like a factory reset of the Biomek? We noticed a small pinhole above the parallel port. When pressed, the Biomek emits a loud continuous beep (doesn't stop even if pressed for more than 10 secs). Does anyone know what that is about?

3. The Hardware and Software Installation Guide talks about "Updating the EPROM". Is there a way to find out if the previous owner updated this EPROM? What would be the consequences for us? Do we have to test with every possible software version?

Thanks again for any input.

It turns out that we had the wrong cable.

Instead of a normal serial cable, what was needed was a "null-modem serial cable".

WinXP with Bioworks Software 3.1a seems to be just fine.
