The Multiport II is a double width NIM intended for use where existing amplifier and HVPS modules are to be combined with a high analog performance, low-cost ADC/MCA. It provides greater flexibility than traditional bus plug-in boards but at a comparable cost. Multiport II can be purchased in versions from one to six inputs. Units with fewer than six inputs can be field upgraded with additional inputs. Two communications interface versions are available: Ethernet/USB and USB only.
