This just arrived from a local aerospace company sale, Snell & Wilcox Magic Dave System Controller & Video Processor Switcher Power Supply unit, the Controller did not come with a power cable but has a BNC cable attached to the Roll Call Port ( which is loose ) on the rear and this connects to the PS Unit. Its strange that neither unit has a model number like so many others online do. The controller says model number "controller", The PS / switcher unit has none, The switcher PS unit powers on to a loud continuous beep.
