BUILDING AN INVERTED BANNER
It is possible to hang a single row of PMCD750 units upside down to make a banner.
Pelco does not provide any special brackets to hang a PMCD750 unit upside down. The method to use is best determined on site due to the many
variables to consider. The ceiling and method used must be capable of sustaining five times the weight of each PMCD750 unit – a total of
340 pounds (154 kilograms) per unit.
The screen supports, which normally hold screens up, will now be above the row of screens. You may wish to devise a way to push the screens
up from the bottom to press them against this support to prevent a gap. It is not necessary to use the screen support parts in an inverted
installation. The screen supports can be used to cover part of the unit, but they are unnecessary in the inverted configuration.
For inverted operation, the picture and menus must be inverted. Refer to the Changing the Picture and Menus section.
