3.3.4.4.2 Puffer Time
Operating the UCI by using a LAN connection in case of high network traffic may lead to
transmission failures. That is why the raw data are temporarily stored in the UCI module.
However, the available memory capacity depends on the amount of raw data to be transported
( → Fig. 12) and thus, is limited.
Fig. 12: Max. buffer time in case of network overload
Tip: If the network failure exceeds the buffer time described above, analog data
may be lost.
If you notice these effects, Thermo Fisher Scientific recommends establishing
a USB connection between the UCI and the Chromeleon server. As the USB
bus is capable of performing real-time operations, overloading effects will not
occur. If a USB connection cannot be established, take appropriate measures to
avoid interruptions of the network communication between the Chromeleon
server and the UCI ( → Recommendations for Network Operation, page 26).
