Using a modem, ComVision will gather data from any remote Opsis system. ComVision's communications software also allows data to be sent via modem to other users. This gives complete freedom to integrate and compare information from a number of sites. It should be noted that the Opsis analyser's own hard disk automatically retains up to two years' raw data. One ComVision may read data from as many as 20 different Opsis analysers, optionally equipped with dataloggers.
Data transfer uses an error-correcting protocol.
The communication may be protected by a password. Furthermore, ComVision allows data export to other computers, connected in the network. ComVision supports Epson Matrix and HP LaserJet, PaintJet and DeskJet for graphic printouts. External printer drivers may also be used. Operation mode ComVision is normally used in a dedicated PC, where it calls the analysers regularly, for example once an hour or once a day.
