The 600 Series LINK Interfaces are buffered, digital interface modules containing four independent RS232 ports for instrument interfacing and IEEE-488/RS232 communication ports for host communication. Each LINK module can service a single LC system or up to three independent gas chromatographs (limited to 2 model types). For GCï¿½s, each RS232 port is capable of receiving two digital detector signals. Digital data acquired from instruments are buffered in the dynamically allocated RAM memory analogous to the PerkinElmer NCI/900A Series Interfaces. CSA, TUV, EMI, and CE-mark certified. Each interface requires, but does not include, one IEEE or RS232 interface cable, plus the appropriate number and type of RS232 cables for supported instruments.
