PE0403 Detailed Description 6.1. Hardware Description The PE0403 as shipped may not have the optimum configuration or component values for all function images. Check the PE0403 schematic against recommendations in the specific CMX734x datasheet. 6.1.1. Power Supplies The board is fitted with four voltage regulators and has a footprint for a fifth regulator. -

Page 20: Function Image
Whenever power is removed from the PE0403 the FI data will be erased from the CMX7240/CMX7340 device. Therefore, whenever power is applied a FI must be loaded via the C-BUS interface. If the PE0403 is used with the PE0002 PC interface, Function Images can be loaded as described in sections 6.3.1, 6.3.2 and 6.3.3. -
