Usage Features
The Media Receiver is designed for seamless integration with Pioneer Plasma Displays. It offers a wide array of connectivity options for various audio and video sources, including component video, S-video, AV, HDMI, and PC inputs. The front panel provides convenient access to INPUT 4 (S-Video, AV in) and PC input. The remote control unit (AXD1492) is the primary interface for operating the device, especially in Service Factory mode.
Service Factory Mode:
This mode allows technicians to perform adjustments and diagnostics.
- Access: Use the supplied remote control unit.
- Functions: Includes information display (version, serial, panel power-down/shutdown logs, temperature, hour meters, pulse meter, P ON counter, digital EEPROM status, HDMI signal info, tuner signal info), function checks (IC tests, FAN control, AFT lock, BSD ANT VOLT, AUTO PRESET CHECK), individual adjustments (CVY/RY/GY/BY GAIN), common adjustments (RGB 1/2, PANEL 1/2), option settings (pattern mask, full mask, peak limiter, dynamic range, EDID write mode, EU CH preset), and initialization settings (sync det, drive mode, side mask level, panel revice, final setup, C temp settings, BSD factory, UART select, CVT auto).
- RS-232C Control: The device supports RS-232C commands for external control and diagnostics. It can be switched between SR+ and RS-232C control modes.
- TRAP Switch: A detection switch is included to prevent panel technology leakage if the upper plate is accidentally opened. This switch is disabled when the unit is turned off. For internal diagnosis, it can be fixed to the OFF position using adhesive tape.
