Network Chromatograph Interface NCI, Intelligent Interface enhances the capabilities of the TotalChrom/Turbochrom chromatography data handling system. The Network Chromatography Interface (NCI) can be connected directly to the network using its own IP address and Ethernet 10Base-T communication. The NCI interfaces are used to collect analog data from chromatographs made by virtually any vendor and of any age. They provide the ability to maintain data collection and retain the data collected in buffered memory, even when the “Acquire” computer or the computer network is unavailable, thus preventing the loss of valuable data. 902 Intelligent Interface with RVP/Relay Board is a dual channel A/D with 256KB RAM memory and RVP/Relay board. Stores up to 120K data points. Unipolar/bipolar operation modes. Requires one IEEE or RS232 interface.
