9.2. Adjusting procedure by use of [RS-232C]
1. Get ready the PC with COM port (RS-232C) running on Windows 95/98/ME/2000/XP operating system, as well as the RS-232C cross cable.
2. Start the unit with the RS-232C cable connected.
3. Start the terminal software. (The freeware readily available on the Internet will do.)
4. Make the following settings.
5. If the settings are correct, the terminal software indicates “ERR” against pressing of the “ENTER” key.
6. After the settings are done correctly, it is possible to make an adjustment by typing in the command shown in the table below and pressing the
“ENTER” key on the keyboard.
7. Command entry is successful if the terminal software indicates “OK” when the “ENTER” is pressed. If “ERR” is shown, retry to enter the command.
8. Send the process mode switching command to switch from the RS232C operation mode to the process mode.
KRSW0001: “ERR” is returned.
KKT10037: When “OK” is returned, the process mode becomes active. When “ERR”, start over from KRSW0001.
9. Send each adjustment command.
10. Key writing
10.1. EDID writing (Main PWB: QPWBXF282WJZZ)
10.2. MAC address writing (Main PWB: QPWBXF282WJZZ) (Except for LC-32LE700UN)
1. Write the MAC key data into IC8453 mounted on the MAIN PWB via RS232C.
2. The data must be written before making the inspection using the checker.
Baud rate 9,600 bps
Data LENGTH 8 bit
Parity bit None
Stop bit 1 bit
Flow control None
Adjustment point Adjustment conditions Adjustment procedure
1 HDMI EDID writing
(Main PWB)
Process mode
Model discrimination check
1) Enter the process mode.
2) Point the cursor to [HDMI EDID WRITE] and press the [ENT]
key.
The writing is complete when [OK] is displayed.
(If not written, HDMI does not function.)
CAUTION: Perform the data writing after setting the model discrimi-
nation. The data based on the model discrimination
information is recorded in EEPROM.
2 Analog RGB EDID writing
(Main PWB)
Inspection mode
File version check
1) Write the EDID data for analog RGB into IC1809 mounted on the
main PWB.
TL1821 ••• I2C clock, TL1823 ••• I2C data
TL1824 ••• 5V, TL1822 ••• GND
TL1848 ••• Write protection (H: WP, L: write enable)
2) Perform the data writing before making inspection using the
checker.
