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 i 2.1 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).
2.3 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. To comply with the WEEE Directive, Kramer Electronics has made arrangements with the European Advanced Recycling Network (EARN) and will cover any costs of treatment, recycling and recovery of waste Kramer Electronics branded equipment on arrival at the EARN facility.
3 Overview The VS-48HN is a high quality 4x8 matrix switcher for HDMI signals. It reclocks and equalizes the signal and can route any input to any or all outputs simultaneously. In particular, the VS-48HN features: Up to 6.75Gbps data rate (2.25Gbps per graphics channel) Suitable for resolutions up to UXGA at 60Hz and for all HD resolutions. Support for HDCP (High Definition Digital Content Protection) HDMI support for 3D, Deep Color, x.v.
3.1 About Fast Switching Older display devices required a longer time between the loss of one digital signal and the introduction of another, as well as a physical disconnection of the interconnecting cable in order to be able to detect and adjust to the new video attributes and parameters. Normal switching, therefore, introduced a 5V signal disconnection along with a delay in switching. Many newer display devices, however, are now capable of “on-the-fly” switching.

3.3 Using the IR Transmitter You can use the RC-IR3 IR transmitter to control the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver (Model: C-A35M/IRR-50). The external IR receiver can be located up to 15 meters away from the machine. This distance can be extended to up to 60 meters when used with three extension cables (Model: C-A35M/A35F-50).
4 Installing in a Rack This section provides instructions for rack mounting the unit.
5 Connecting the VS-48HN 4x8 HDMI Matrix Switcher i Always switch off the power to each device before connecting it to your VS-48HN. After connecting your VS-48HN, connect its power and then switch on the power to each device. To connect the VS-48HN 4x8 HDMI Matrix Switcher as illustrated in the example in Figure 3: 1. Connect up to four HDMI sources (for example, DVD players) to the IN HDMI connectors. You do not have to connect all the sources. 2.

6 Operating the VS-48HN 4x8 HDMI Matrix Switcher This section describes: 6.1 Switching an input to an output (see Section 6.1) Acquiring the EDID (see Section 6.2) Storing and recalling switch settings (see Section 6.3) Changing the port switching speed (see Section 6.4) Setting HDCP on or off (see Section 6.5) Resetting the VS-48HN IP parameters (see Section 6.6) Switching between Protocol 2000 and Protocol 3000 (see Section 6.
6.2.1 Acquiring the EDID from One Output Note: You can assign the EDID from one output to any or all of the four inputs. To acquire the EDID from a display device connected to one of the outputs: 1. Press the EDID and STO buttons simultaneously and hold them for 3 seconds. Both buttons flash. 2. Press the input button to which the EDID is copied. The selected input number flashes on the display. 3. Select the output from which the EDID is to be acquired. 4. Press the EDID button.
7. Select the output from which the EDID is acquired (for example, OUT 6). 8. Press the IN 3 button. The IN 3 button stops flashing. 9. Press the input buttons to which you want to copy the EDID (for example, IN 1 and IN 3). 10. Make sure that the relevant input numbers flash on the display. 11. Press the EDID button. The process is complete when the display returns to normal. 6.2.3 Acquiring the Default EDID To store the default EDID on a selected input (for example, Input 2): 1.
To store a preset (for example, to preset 10): 1. Configure the switching as required for the preset. 2. Press the STO button. The STO button flashes. 3. Select an OUT or IN SELECT button to store the device setting (for example, IN 2 for preset 10). 4. Press the STO button to store the current setup. If you do not press the STO button within 10 seconds the procedure automatically times out. To recall a preset (for example, preset 10): 1. Press the RCL button. The RCL button flashes. 2.
2. Press the RCL and EDID buttons at the same time. The RCL and EDID buttons flash, and the display indicates the switching speed mode of each port. IN 1, IN 2 and IN 3 are illuminated (red). 3. Press one or more (or ALL) of the OUT buttons to select the port to change. The selected port setting on the LED display flashes. 4. Press one of the IN 1/IN 2/IN 3 button to toggle the switching speed, (to Extra fast/Fast/Normal, respectively). The switching speed displayed changes for the selected ports. 5.
3. Press an input button to change its status. You can press one or more inputs. 4. Once you have changed the status of HDCP on the inputs as desired, press the EDID to save the changes and exit the HDCP enable/disable mode to return to normal operation. Note: If the EDID button is not pressed within about 12 seconds, the device exits the port speed switching mode automatically and all changes are lost. 6.6 Resetting the IP Parameters i This procedure resets only the IP related parameters.
6.8 Connecting via RS-232 You can connect to the VS-48HN via an RS-232 connection using, for example, a PC. Note that a null-modem adapter/connection is not required. To connect to the product via RS-232: Connect the RS-232 9-pin D-sub on the rear panel of the VS-48HN via a 9-wire straight cable (only pin 2 to pin 2, pin 3 to pin 3, and pin 5 to pin 5 need to be connected) to the RS-232 9-pin D-sub port on your PC 6.

10 Kramer Protocol 2000 The Kramer Protocol 2000 RS-232/RS-485 communication uses four bytes of information as defined below. All the values in the table are decimal, unless otherwise stated.
Instruction Codes for Protocol 2000 Instruction Definition for Specific Instruction # Input Description 0 1 RESET VIDEO SWITCH VIDEO 3 STORE VIDEO STATUS RECALL VIDEO STATUS REQUEST STATUS OF A VIDEO OUTPUT REQUEST WHETHER SETUP IS DEFINED / VALID INPUT IS DETECTED LOCK FRONT PANEL 4 5 15 30 31 56 61 62 0 Set equal to video input which is to be switched (0 = disconnect) Set as SETUP # 0 Set equal to video output which is to be switched (0 = to all the outputs) 0 - to store 1 - to delete 0 1 2,
If the request for identification is sent with the INPUT set as 3 or 4, the appropriate machine sends its software version number. Again, the reply would be the decimal value of the INPUT and OUTPUT - the INPUT representing the number in front of the decimal point, and the OUTPUT representing the number after it. For example, for version 3.5, the reply to the request to send the version number would be (HEX codes): 7D 83 85 81 (i.e. 128dec+ 3dec for 2nd byte, 128dec+ 5dec for 3rd byte).
11 Protocol 3000 By default, the VS-48HN is set to Protocol 2000 (see Section 10) but is also compatible with Kramer’s protocol 3000. i Note that the VS-48HN needs to be set to protocol 2000 in order to use the IR remote control. The VS-48HN can be operated using serial commands from a PC, remote controller or touch screen using the Kramer Protocol 3000. This section describes: 11.1 Kramer Protocol 3000 syntax (see Section 11.1) Kramer Protocol 3000 commands (see Section 11.
11.1.2.1 Device Long Response Echoing command: Start Address (optional) Body Delimiter ~ device_id@ Command SP [Param1 ,Param2 …] result CR LF CR = Carriage return (ASCII 13 = 0x0D) LF = Line feed (ASCII 10 = 0x0A) SP = Space (ASCII 32 = 0x20) 11.1.3 Command Terms Command A sequence of ASCII letters ('A'-'Z', 'a'-'z' and '-'). Command and parameters must be separated by at least one space.
Command chain separator character When a message string contains more than one command, a pipe ( '|' ) character separates each command. Spaces between parameters or command terms are ignored. 11.1.4 Entering Commands You can directly enter all commands using a terminal with ASCII communications software, such as HyperTerminal, Hercules, etc. Connect the terminal to the serial or Ethernet port on the Kramer device. To enter CR press the Enter key. ( LF is also sent but is ignored by command parser).
