Dear Hakan,
I spoke with my engineer here in Australia regarding your problem, the error you are seeing maybe due to the fact your 3 com 3c900 or Netgear FA 310 (these are the preferred cards for DX-LAN communication) does not have the appropriate driver to communicate with PeakNet 5.2. I would also recommend you try to get hold of a patch for PeakNet 5.2. If you need any of these driver updates or patch we maybe able to talk off line and I can attempt to send them to you. When initializing these cards insure all modules are turned on and connected to the DX-LAN network. I would also check in the power up screen of each module to insure your BIOS is 30.00 or higher. Locally we have not gone above Windows 2000 for older versions of PeakNet 5.xx. PeakNet is getting really old its been discontinued for many years, and to be honest its been quite a while since I have used it myself and I have been with Dionex for decades I assure you. As such I offer this advice under the caveat of “all care and no responsibilityâ€
