Page 4: Introduction To Vpu3400
VPU3400 Introduction to VPU3400 The VPU3400 is a specially designed video processor for synchronic LED display. It is an image processor that can scale up and down the VGA and video images. It also does the signal selection. With the new technology of high precision A/D conversion and automatic noise reduction as well as the capability of changing from interlace to progressive scanning, the VPU 3400 boasts the function of putting out excellent video signal with high definition. -

It shows basic information of the operating interface. “Exit” exit from the current menu and return to the previous menu. - Page 6 “S-Video” video input Notes: 1）There are two video input channels in VPU3400. Each channel accepts one video sig nal input. When different video signals are fed to the processor at the same time, the user can get the function of “Picture In Picture”.

LDU 3000 through an optical fiber. Signals like DVD, DC and TV signal should be connected to the video source input port of VPU3400, while DVI signal should be connected to the im- age port of VPU3400. Operation and parameter setting are done through the RS-232 port communication or operation on the front panel of the VPU3400. -

3.1 Selection of video source Before hands-on operation, we should recognize the interface below, which is shown on the LCD when the VPU3400 is under normal working circumstances. Current video source: “YPrPb”; Users can select different video sources according to their actual need. - Page 9 Manual VPU3400 Selection of the Video Source Steps to select a video source: Enter the function menu Choose “Select Video” Select the video source Properly set a video signal input on the equipment according to the video signal connection.

Page 14: Setting Video Zoom Window
When the video display window is different in size from the size of the video signal, the VPU3400 can compress and expand the video signals to match the exact screen size. VPU3400 provides 6 zooming modes: namely 16:10, 16:9, 5:4, 4:3 and 3:2 The definitions are：... -

Sometimes you need to use more than one video processor to process the video signals. When you use three VPU3400s, for example, you need to set one VPU3400 as the master machine and two other VPU3400s as slave machines. Accordingly, you also need to set the starting column in the second channel in each slave VPU3400. -

We can check some of the most basic information about the video processor VPU and even the signal distributor LDU by looking up the VPU3400. This information include： 1) CPU version number of the VPU, FPGA firmware version number, serial number and IP address. -
Page 19: Vpu3400 Self-Diagnosis
Steps to perform self-diagnosis： 1) Use a DVI signal cable to connect the input and output terminals of the VPU3400. 2) Enter menu ”System Setting” ”System Test” Check the test result. 5.3 Save the Current Setting to Factory Default Value VPU3400 can save the current setting to as factory default value. - Page 20 Manual VPU3400 Subject to changes and misprints ALGE-TIMING GmbH Rotkreuzstraße 39 A-6890 Lustenau Austria Tel: +43-5577-85966 Fax: +43-5577-85966-4 office@alge-timing.com www.alge-timing.com Page 20...
