7 Capturing the EDID from a Display Device

To capture the EDID from a display device:

1.Using a Philips screwdriver, remove the four screws holding the faceplate to the PCB assembly.

2.Using a short cable (for example, Kramer model number C-MGM/MGM-1), connect the PC IN input 15-pin HD connector on the WP-121to the XGA connector of the display and turn the display on.

3.Ensure that the rotary switch (see Figure 8) is in position 0. If it is not, use a small screwdriver to turn it to 0.

4.Connect the 12V DC power adapter to the power terminal block (see Figure 4) on the WP-121and connect the adapter to the mains electricity.

5.Press the EDID capture button (see Figure 8).

The EDID status LED flashes slowly several times. The new EDID is captured when the LED stops flashing and lights solid.

6.Unplug the power adapter from the mains and disconnect it from the WP-121.

7.Replace the faceplate and secure the four screws removed in Step 1.

To set a preconfigured EDID:

1.Using a Philips screwdriver, remove the four screws holding the front panel to the rear PCB assembly.

2.Using a small screwdriver, turn the rotary switch (see Figure 8) to the required position as defined in the table below.

3.Connect the 12V DC power adapter to the power terminal block (see Figure 4) on the WP-121and connect the adapter to the mains electricity.
