1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront video, audio, presentation, and broadcasting professionals on a daily basis.
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 i 2.1 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).
2.2 Safety Instructions ! 2.3 Caution: There are no operator serviceable parts inside the unit Warning: Use only the Kramer Electronics input power wall adapter that is provided with the unit Warning: Disconnect the power and unplug the unit from the wall before installing Recycling Kramer Products The Waste Electrical and Electronic Equipment (WEEE) Directive 2002/96/EC aims to reduce the amount of WEEE sent for disposal to landfill or incineration by requiring it to be collected and recycled.
3 Overview The VS-311H is a high-performance 3x1 HDCP- compatible automatic switcher for HDMI signals, digital audio (S/PDIF) signals and stereo audio signals. The VS-311H switches any one of three HDMI, HDCP compliant sources to a single display device, on HDMI connectors with the corresponding: Digital audio (S/PDIF) input signals switched to an S/PDIF output, on RCA connectors and/or Unbalanced stereo audio input signals on 3.
3.1 Defining the VS-311H Automatic HDMI/Audio Switcher This section defines the VS-311H. Figure 1: VS-311H Automatic HDMI/Audio Switcher # Feature Function 1 IR Receiver The red LED lights when receiving signals from the infrared remote control transmitter 2 POWER Switch Illuminated switch for turning the unit ON or OFF 3 INPUT SELECT Buttons Press the INPUT button to select the input to switch to the output (from 1 to 3).
# Feature Function 13 IN HDMI Connectors Connect to the HDMI sources (from 1 to 3) 14 ETHERNET Connector Connect to the PC or other Serial Controller through computer networking 15 FACTORY RESET Button Press the ETHERNET factory reset button to reset to the factory default definitions: IP number 192.168.1.39 Mask – 255.255.255.0 Gateway – 192.168.1.1 First, disconnect the power and then connect it again while pressing the RESET button.
4 Connecting the VS-311H i Always switch off the power to each device before connecting it to your VS-311H. After connecting your VS-311H, connect its power and then switch on the power to each device. To connect the VS-311H as illustrated in the example in Figure 2: 1. Connect an HDMI source (for example, an HDMI DVD player) to the IN 1 HDMI connector and connect the digital audio input to the IN 1 S/PDIF RCA connector.
Figure 2: Connecting the VS-311H Automatic HDMI/Audio Switcher 4.1 Setting the DIP-Switches This section describes the machine set-up and DIP-switch selection. By default, all the VS-311H DIP-switches are set to OFF. Figure 3 describes the VS-311H unit DIP-switches.
DIPS 1, 2, 3 Function Priority setup 4 AUTO Description Set the inputs priority OFF: manual mode, switch between channels manually; ON: automatic mode, inputs switch automatically to the output according to the priority setup Inputs 1, 2 and 3 can be set in priority according to your needs. The VS-311H switches to the secondary input upon loss of the primary input signal, and back to the primary input when a signal is detected. The following table describes the priority setup: 4.
connect the appropriate input number (input 1, 2 or 3) pin on the REMOTE terminal block connector to the G (Ground) pin, as Figure 4 illustrates. When in the manual mode (DIP-switch 4 set to OFF), you can switch an input to the output using the front panel INPUT SELECT button. Note that unless the connection is permanent, the VS-311H will revert to an automatic switcher when the connection is removed. ! DO NOT Connect more than one PIN to the Ground PIN at the same time.
Hardware flow control is not required for this unit. In the rare case where a controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on the controller side. Method B (Figure 6)—Connect the RS-232 9-pin D-sub port on the unit via a straight (flat) cable to the null-modem adapter, and connect the null-modem adapter to the RS-232 9-pin D-sub port on the PC. The straight cable usually contains all nine wires for a full connection of the D-sub connector.
After connecting the Ethernet port, configure your PC as follows: 1. Right-click the My Network Places icon on your desktop. 2. Select Properties. 3. Right-click Local Area Connection Properties. 4. Select Properties. The Local Area Connection Properties window appears. 5. Select the Internet Protocol (TCP/IP) and click the Properties Button (see Figure 7). Figure 7: Local Area Connection Properties Window 6. Select Use the following IP Address, and fill in the details as shown in Figure 8. 7. Click OK.
Figure 8: Internet Protocol (TCP/IP) Properties Window 4.5.2 Connecting the ETHERNET Port via a Network Hub (StraightThrough Cable) You can connect the Ethernet port of the VS-311H to the Ethernet port on a network hub or network router, via a straight-through cable with RJ-45 connectors. 4.5.3 Control Configuration via the Ethernet Port To control several units via the Ethernet, connect the unit via the Ethernet port to the LAN port of your PC.

6 Protocol 2000 This RS-232/RS-485 communication protocol uses four bytes of information as defined below. For RS-232, a null-modem connection between the machine and controller is used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit. 6.
6.2 Instruction Codes All the values in the table are decimal, unless otherwise stated Instruction Codes for Protocol 2000 Instruction Definition for Specific Instruction # Description Input Output Notes 1 SWITCH VIDEO Set equal to video input that is switched (0 = disconnect) Set equal to video output that is switched (0 = to all the outputs) 2, 15 NOTES on the above table: NOTE 2 – These are bi-directional definitions. If the switcher receives the code, it performs the instruction.
