XRS Camera. Please refer to the instructions included in Appendix A, B respectively for Gel
Doc
 XR/ ChemiDoc XRS cable wiring.
The controls for the Motorized Zoom Lens can be operated from the membrane touch pad of
the Universal Hood II or from the PC using the buttons that appear in the window when the
option Gel Doc
 XR or ChemiDoc XRS is selected in the File Menu of the Quantity One
program. To use this option it is necessary to connect the Universal Hood II serial port
(DB25) (on the back left side) to the COM1 of the computer. The PC/Mac cable is included.
Note: In the case when a Mac has a USB port instead of the serial port, use the USB to
serial adapter (included with Mac systems) to control the lens via software.
