The Graflex DIS-III is our 3rd generation digital motorized zoom lens control system, it includes a user friendly GUI, complete protocol details, and a relatively small PCB. The DIS-III allows the user to control the zoom, focus, and iris functions of a previously analog component. We provide full protocol details allowing the customer to control the lens according to their requirements and not (necessarily) via the Graflex GUI. Position potentiometers may be “mated” to the FOV via a calibration process; the accuracy of “counts” provided by the position pots is limited to the accuracy of those potentiometers. The user may select “auto” iris or manual iris modes; manual iris mode allows the user to adjust the iris at any position via the GUI. The DIS-III holds distinct advantages over the previous generation system (DIS-II) in that the user can now control multiple sensors via the same GUI, provides for minimized voltage losses and latency, and is compatible with VISCA and PELCO D. The DIS-III also provides ETHERNET communication capability. We will also private label the DIS-III (and GUI) making it an integral part of the customer’s unique system. The DIS-III will interface with and control virtually any motorized zoom lens.
