Overview

KRAMER ELECTRONICS, LTD.

3 Overview

The VP-4x4 is a true 4x4 matrix switcher for VGA / XGA signals and stereo

balanced audio signals. The VP-4x4 enables the user to simultaneously route

any or all of the 4 inputs to any or all of the 4 outputs.

In addition the VP-4x4 includes:

 Video bandwidth of 440 MHz that ensures transparent VGA / XGA

performance

 Easy-to-connect detachable terminal block connectors on which the audio

signals reside

 DC coupled inputs and outputs

 Audio-follow-video and breakaway options

 Storing and recalling setup options

 “Take” button for precise switch control

 “Lock” button to prevent tampering with the front panel

 The ability to control via the front panel buttons, or remotely by RS-485

or RS-232 serial commands transmitted by a touch screen system, PC, or other

serial controller

To achieve the best performance:

 Connect only good quality connection cables, thus avoiding interference,

deterioration in signal quality due to poor matching, and elevated noise levels

(often associated with low quality cables)

 Avoid interference from neighboring electrical appliances that may

adversely influence signal quality

 Position your Kramer VP-4x4 in a location free from moisture and away

from excessive sunlight and dust

port on the Master VP-4x4 unit, as Figure 2 illustrates (depending on whether

the PC has a 9-pin or 25-pin connector)

Figure 2: Connecting a PC without using a Null-modem Adapter

To connect a PC to the VP-4x4, using a Null-modem adapter:

 Connect the RS-232 DB9 rear panel port on the Master VP-4x4 unit to

the Null-modem adapter and connect the Null-modem adapter with a 9 wire

flat cable to the RS-232 DB9 port on your PC, as Figure 3 illustrates

1 Switch OFF the power on each device before connecting it to your VP-4x4. After connecting your VP-4x4, switch on its

power and then switch on the power on each device

To set the Audio-follow-video (AFV) option:

1. Press the AFV button.

The AFV button illuminates. The audio will follow the video.

2. If the audio configuration differs from the video configuration, both the

Audio IN STATUS 7-segment displays and the AUD button will blink

and require reconfiguring for AFV operation.

3. Press the TAKE button to confirm the modification (reconfiguring the

audio according to the video).

5.2.2 Setting the Breakaway Option

To set the Breakaway option:

1. Press either the AUD (for audio control only) or the VID (for video

control only) button.

2. If the AUD button illuminates all switching operations relate to the Audio

section.

3. If the VID button illuminates all switching operations relate to the Video

section.

5.3 Switching OUT-IN Combinations
