2.1 Achieving the Best Performance

To achieve the best performance:

Use only good quality connection cables (we recommend Kramer high-

performance, high-resolution cables) to avoid interference, deterioration in

signal quality due to poor matching, and elevated noise levels (often

associated with low quality cables)

Do not secure the cables in tight bundles or roll the slack into tight coils

Avoid interference from neighboring electrical appliances that may adversely

influence signal quality

Position your Kramer VP-426 away from moisture, excessive sunlight and

dust

This equipment is to be used only inside a building. It may only be

connected to other equipment that is installed inside a building.

4 Connecting the VP-426

Always switch off the power to each device before connecting it to your

VP-426. After connecting your VP-426, connect its power and then

switch on the power to each device.

To connect the VP-426 as illustrated in the example in Figure 2:

1. Connect a computer graphics video source to the PC IN 15-pin HD

connector and a PC audio source to the PC AUDIO IN 3.5mm mini jack

(both for example, from a PC).

When connecting to a component source (YPbPr), connect as shown

here:

Ground

2. Connect an HDMI video source to the HDMI IN connector (for example, from

a DVD player).

3. Connect the PC OUT 15-pin HD connector and the AUDIO OUT 3.5mm mini

jack to a computer graphics with audio acceptor (for example, an analog

display and an unbalanced amplifier).

When connecting to an XGA acceptor (RGBHV), connect to the

acceptor’s XGA connector

4. Connect the HDMI OUT connector to an HDMI acceptor (for example, an

LCD display with speakers).

5. If desired, connect the REMOTE terminal block connector to contact closure

switches (see Section 4.1).

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

adapter to the mains electricity (not shown in Figure 2).

4.1 Connecting the Remote Terminal Block

The contact closure remote control pins operate in a similar way to the INPUT

SELECT button. Using the contact closure remote control (also known as push-to-

make momentary contact) you can select the PC or the HDMI input. To do so,

momentarily connect the required input pin (HDMI or PC) on the REMOTE

terminal block connector to the G (ground) pin, as shown in Figure 3.

Do not connect more than one PIN to the GND PIN at the same time.
