Connecting the VA-1VGAN EDID Capture

5 Connecting the VA-1VGAN EDID Capture

In the example illustrated in Figure 2, a projector is disconnected from a PC

in order to reinstall it at a distance, after the PC has read the projector’s

acquired EDID from the VA-1VGAN. The projector is then reconnected,

without the need to reboot the system.

The configuration illustrated in Figure 3 requires two separate stages:

 The VA-1VGAN needs to acquire the projector’s EDID

information (see section 5.1)

 The PC is connected to the VA-1VGAN, letting it read the

projector’s EDID information even if it is not connected to the PC

(see section 5.2).

The projector can now be reconnected at a distance to the PC via

the VA-1VGAN.

5.1 Acquiring the EDID

To use the VA-1VGAN to acquire the EDID information, as illustrated in

the example in Figure 2, do the following:

1. Connect the OUTPUT VGA connector to the input VGA connector of the

display (for example, a projector), using a short cable

2. Connect the 5V DC power adapter to the power socket and connect the

adapter to the mains electricity

(not shown in this illustration).

The ON LED should light.

3. Press the CAPTURE EDID button.

The ON LED turns off while the EDID information is read and stored in the

VA-1VGAN non-volatile memory. When the ON LED lights again, the

EDID is stored.

4. Disconnect the projector’s VGA connector from the OUTPUT VGA on the

VA-1VGAN.

5. Disconnect the power source.

1 The EDID is carried over pins 12 and 15 of the VGA connector. It is essential that the cable used for capturing the EDID

passes all 15 pins

2 Also make sure that the projector is connected to the power supply
