Introduction
The SS420x is an intelligent instrument interface box designed
to collect analog data, and input and output digital signals.
The SS420x attaches to the controlling computer via a
standard RS-232C serial interface. It contains the circuitry of
the SS420 interface card, along with an additional CPU, one
megabyte of RAM for long-term collection of chromatography
data and the ability to retain all the settings required by the
SS420.
The SS420x provides a seamless interface to the controlling
computer that is independent of any specific hardware
architecture; e.g., it doesn’t require a PC slot or the associated
interrupt and I/O address settings. Additionally, by placing
these capabilities outside of the PC, the SS420x off-loads the
processor power required by the original SS420 card and
provides the capability of retaining data and controlling
chromatography equipment, regardless of the state of the
controlling computer.
