5 Using the XGA Switcher / Distribution Amplifier

To connect your VP-242 XGA Switcher / Distribution Amplifier, as the

example in Figure 2 illustrates, do the following:

1. Connect up to 4 HD15F outputs to the respective acceptors, 1-4.

2. Connect up to 2 sources to the respective inputs:

 Connect source 1 (for example, a PC) to the INPUT 1 HD15F connector

and release the INPUT 1 ID BIT button.

 Connect source 2 (for example, a notebook) to the INPUT 2 HD15F

connector and push in the INPUT 2 ID BIT button.

3. Set the SELECT button, as follows:

 Release the SELECT button to route the INPUT 2 signal to up to 4 acceptors

 Push in the SELECT button to route the INPUT 1 signal to up to 4 acceptors

4. Connect the 12V DC power adapter to the power socket and connect the

adapter to the mains electricity.

5. Adjust the video EQ. (equalization) compensation and the video signal

level, as required, to overcome losses in the connecting cables and

achieve the highest quality picture.

1 Sometimes notebook computers refuse to output a VGA signal to an external VGA monitor. By setting the ID Bit to ON

(and using pin # 4 on the VGA connector that is normally unused), the notebook will output to an external VGA monitor
