1. SS420x Analog Digital Converter Migration to 35900E Dual Channel Interface with Modular Input Output for EZChrom Elite CDS Specifications The purpose of this document is to describe the key differences between the SS420x and the 35900E analog to digital converters for chromatography detectors used with EZChrom Elite Chromatography Data System EZChrom Elite communicates with the 35900E over a LAN connection and does not control the BCD connector used to control an autosampler The channels in the 35900E can be configured independently within one generic instrument as described below Dual Channel or Single Channel Functionality The Agilent 35900E functions are divided into an A channel and a B channel for individual or combined run control To have a run simultaneously start the data collection and transmission for both channels both channels are configured as a single 35900E interface assigned to the same instrument To have the run start the data collection and transmission for a single channel only that channel is assigned to the 35900E interface for the instrument The unassigned channel can be configured as a different interface assigned to an adjacent instrument You can configure more than one 35900E Interface device per instrument Single Channel Operation Dual Channel Operation In this mode the Agilent 35900E operates as two In dual channel operation the Agilent 35900E independent single channel interfaces each provi2.
