The D3Prog is a service tool for firmware updates of GLP devices and should not be missing in any technician's bag.

Via USB or Sub-D 9pin, different firmware versions can be stored on different memory locations via PC, which can then be conveniently loaded onto the fixture via DMX Link (RS458/DMX) or AVR/ISP at the touch of a button.

To bypass unnecessarily required XLR adapters, the D3Prog is equipped with both an XLR 5-pin female and an XLR 3-pin female connector. Multiple fixtures in a DMX line can also be brought up to speed simultaneously, saving an enormous amount of time.

For maximum service convenience, the D3prog is battery-powered and can therefore be used independently of mains voltage.
