Servicing Using Only The Media Receiver - Pioneer PRO-R04U Service Manual

6.6 SERVICING USING ONLY THE MEDIA RECEIVER

For servicing of the PDP-434HD and PDP-504HD-series Plasma Display using only the Media Receiver, the following two
methods can be used:
¶ Remote controlling using SR connections
About connections
• Connect the SR OUT connector of a Pioneer product having that connector (a DVD in the following example) and the SR IN connector of the
Media Receiver, using the SR cable. As the remote control sensor is not provided with the Media Receiver, this connection is required for
using the remote control unit if the panel is not available. In this case, aim the remote control unit at the remote control sensor of the device
(DVD in this case).
• Connect either the audio or the video output of the device (DVD in the example) and the corresponding audio or video input of the Media
Receiver, using a cable with phono plugs. This connection is required in order to use ground in common with the SR cable, because with the
SR cable connection the ground connection for signal reference is not available. In the example, the audio L channel is used, but the audio
R channel or video can be used instead.
• If the plasma display for a previous model, such as the PDP-433P or PDP-503P, is available, servicing while checking displays or using the
menus is possible. For this, connect only the DVI connectors (white) of the Media Receiver and the plasma display. The MDR connector of
the Media Receiver must not be used, even though it has the same shape and number of pins, because signals assigned to the connectors
differ. Using the MDR connector may damage the unit.

¶ RS-232C control using a PC
As the SR+ system is selected at shipment, to use RS-232C control, RS-232C must be selected beforehand using the remote control unit and
by making the above connections. For details, see "6.3. USING RS-232C COMMANDS."
For connection with the PC, use a straight cable.

¶ Note on connection
If the MDR connector of the PDP-434HD or -504HD-series is used, it is considered that the PDP-434P (or -504P) is connected, and the Media
Receiver operates on such precondition, which may result in a failure of the Media Receiver. Be sure not to connect to the MDR
connector. (Do NOT use the MDR connector when servicing the Media Receiver alone.)
