6.1.2 USING RS-232C COMMANDS

For the PDP-507XC, PDP-507XG and PDP-507XDA 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.
