Interfacing a flow cytometer computer with a PC-based patient information system.

We have established an interface between our flow cytometer's computer and the personal computer (PC) which supports our patient database system. The PC has been equipped with a commercially available IEEE-488 bus interface board which is connected to the interface bus of the cytometer's Hewlett-Packard 9000/300 computer (HP). The PC is set as a bus device with the same address as that of the HP's printer. It is programmed to examine the stream of data sent to the printer and extract from it and store in an MS-DOS text file selected information which subsequently may be transferred to the database system.
