VM-4DP - Getting Started

2 Getting Started

We recommend that you:

 Unpack the equipment carefully and save the original box and packaging

materials for possible future shipment

 Review the contents of this user manual

Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).

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 VM-4DP 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.

VM-4DP - Connecting the VM-4DP

5 Connecting the VM-4DP

Always switch off the power to each device before connecting it to your
VM-4DP. After connecting your VM-4DP, connect its power and then
switch on the power to each device.

To connect the VM-4DP as illustrated in the example in Figure 3:

1. Connect a DP source (for example, a computer graphics source) to the DP
INPUT connector.

2. Connect the DP output connectors (not all the outputs need to be
connected), to up to four DP acceptors (for example, displays).

3. Connect the power cord to the mains electricity (not shown in Figure 3).

4. Turn ON the POWER on the rear panel.

5. Acquire the EDID, see Section 6.

VM-4DP - Acquiring an EDID

9

6 Acquiring an EDID

The VM-4DP initially operates with the default EDID. This means that you can turn ON
the power before connecting any of the acceptors or the source.

You can acquire the EDID from:

 The default EDID, see Section 6.1
 A connected output, see Section 6.2

6.1 Acquiring the Default EDID

To acquire the default EDID, do the following:

1. Press the SELECT button, as required, to reach a disconnected output.
The selected output LED flashes.

2. Press the READ button.
The READ button flashes.
The new EDID of the selected output is stored in the non-volatile memory
and passed to the input when the READ button no longer flashes.

6.2 Acquiring the EDID from a Connected Output

To acquire the EDID, from a selected output, do the following:

1. Press the SELECT button, as required, to reach the desired connected
output from which you want to acquire the EDID.
The selected output LED flashes.

2. Press the READ button.
The READ button flashes.
The new EDID of the selected output is stored in the non-volatile memory
and passed to the input when the READ button no longer flashes.
