I had my 6890 Plus GC connected to Chemstation B04.02 through a G1369B LAN card recently. Today I had a warning #103 "Sig 1 buffer full" shown in the GC display, probably because the PC went to saver mode over the past couple of days. I restarted the GC and PC, but could not reestablish the connection. The Chemstation software was able to initialize, but once it got into the software interface, on the log, it says: "Chemstation failed to connect to 6890 at 10.1.1.101". The pinging is okay. Any suggestions how to solve the problem? Thank you!
