DDC (Plug & Play)

This monitor supports the VESA DDC (Display Data Channel) standard.

DDC is a signal standard for carrying out Plug & Play functions on the monitor or PC. It transfers information such as degree of resolution between the monitor and PC. You can use this function if your PC is DDC compliant and if it is set so that it can detect the Plug & Play monitor.

There are many varieties of DDC due to the differences between systems. This monitor works with DDC1 and DDC2B.

2-5. INSTRUCTIONS FOR INSTALLING A VESA

COMPLIANT ARM

An arm based on the VESA standard can be attached to the monitor. The arm must be purchased separately.

When choosing the arm to be installed please take note of t he following points.

• The arm should be compatible with the VESA standard, and there

must be a gap of 75mm x 75mm between the screw holes on the section to be attached.

• The arm must not fall off or break off after being attached to the

monitor.

CAUTION

Be careful not to cut or jam your fingers.

Note: Do not bend the signal cable or the AC adapter cable nor

place weight on them. Doing so could lead to damage.

1. Turn off the power switch and remove the power plug from the power source.

2. Remove the rear cover, stand cover and adapter cover.

To remove them follow steps 1, 2, and 3 of Connecting the monitor to a power source.

3. Remove the AC adapter from the stand.

4. Being careful not t o damage the monitor, spread out a soft cloth and lay the monitor on it display-side down.

2. Adjust by pressing the Note: The BRIGHT bar automatically disappears several seconds

5. Remove the four screws and then remove the stand from the monitor.

Information

The stand is specially made for use with this monitor. Once having removed the stand, never attempt to attach it to another device. Once having removed the screws, store them together with the stand and if the stand is ever reattached be sure to use the original screws. Using different screws could lead to malfunction.

6. Attach the rear cover. To attach it follow step 8 of Connecting the monitor to a power

source.

7. Attach the arm to the monitor with four screws.

Information

The screws used to attach the arm should be M4 screws with a length of 4 mm ~ 6 mm protruding from the surface to be attached. Using different screws could lead to malfunction or may lead to the monitor falling off, internal damaged, personal injury.

2-1. CPU

The PW164 incorporates an 80186-compatible CPU. The CPU incorporates 32-Kbyte RAM in addition to peripheral de-

vices. The CPU directly controls the following memory and I/O: built-in RAM,

flash memory, built-in peripheral devices, scaler-contained 10 registers. The other devices are controlled from the general port through

the I

C bus.

The memory space of the CPU is equal to the capacity of the flash memory.

Allocated on the memory space are flash memory, main memory, PW164-incorporated I/Os, external chip select. You cannot access to the area of flash memory with which these spaces overlap.

The clock speed of the CPU is 43.2 MHz (14.4 MHz in the power save mode).

2-2. Peripheral device incorporated in the CPU

The PW164 incorporates general I/O ports (16 bits), timer (2 ch + watchdog), interrupt controller, UART, and IR decoder.

[8] BR24C21, BR24C01A

A 1-Kbit E2PROM BR24C21 is used for analog DDC, and a 1-Kbit

PROM BR24C01A is used for digital DDC. Analog supports DDC1/DDC2B, and digital supports DDC2B alone. In the DDC1 mode, data can be read from the SDA (RGSA) by

inputting a clock to the VCLK (GVS1). In the DDC1 mode after the power is turned on, data can be read in

the order of "last address", "0h address data", and "1h address data" with addresses automatically incremented.

When the SCL (RGSL) is changed from H to L, the DDC1 mode is changed to DDC2B mode after this clock.

To change the DDC2B mode to the DDC1 mode, turn the power off and on again.

Digital supports DDC2B mode alone.

[6] HN58X2416

A 16-Kbit E2PROM HN58x2416 is used for storing data such as user information.

The HN58x2416 uses I The slave addresses for the HN58x2416 are A0H - AFH and they

need to be changed according to memory addresses which data is read from or written to.

The WP (write protect) pin of the HN58x2416 is not used and thus it is possible to rewrite all areas.

C for reading and writing data.
