How to switch from SR+ to RS-232C
For the PDP-434HD and -504HD series Plasma Displays, the circuitry is structured as shown in the diagram below to support
the SR+ system. Controlling with either the SR+ system or RS-232C commands can be selected. As the SR+ system is
selected at shipment, to control with RS-232C commands in servicing it is necessary to switch the paths. After servicing, be
sure to return the setting to the SR+ system.
