Installing the VS-88H on a Rack 5 Installing the VS-88H on a Rack This section provides instructions for rack mounting the unit.
Connecting a VS-88H 8x8 HDMI Matrix Switcher 6 Connecting a VS-88H 8x8 HDMI Matrix Switcher To connect the VS-88H 8x8 HDMI Matrix Switcher, as illustrated in the example in Figure 2, do the following 1: 1. Connect2 up to eight HDMI sources (for example, DVD players) to the eight INPUT HDMI connectors. 2. Connect3 the eight OUTPUT HDMI connectors to up to eight HDMI acceptors (for example, LCD displays with built-in speakers). 3.
Operating the VS-88H 8x8 HDMI Matrix Switcher 7 Operating the VS-88H 8x8 HDMI Matrix Switcher This section describes how to: • Route an input to an output (see section 7.1) • Acquire the EDID (see section 7.2) • Store and recall a setting (see section 7.3) • Control the machine via RS-232 (see section 7.4) • Control the machine via the ETHERNET port (see section 7.5) 7.1 Switching an Input to an Output Press an output key, followed by an input key to route this input to that output. 7.
Operating the VS-88H 8x8 HDMI Matrix Switcher 7.2.2 Acquire an EDID from Several Sets of Inputs and Outputs To acquire the EDID for more than one output (for example, OUT 1 to IN 1 and OUT 6 to IN 3), do the following: 1. Turn the VS-88H ON. 2. Connect the required acceptor to the output from which you want to acquire the EDID. 3. Press the EDID and STO buttons simultaneously and hold them for 3 seconds. Both buttons flash. 4. Press the input button to which the EDID will be copied (for example, IN 1).
Operating the VS-88H 8x8 HDMI Matrix Switcher 4. Press the OFF button until a "0" (zero) appears on the display. 5. Press the EDID button. The process is complete when the display returns to normal. 7.3 Storing and Recalling a Setting You can use the STO and RCL buttons to store up to 16 setups and then recall them. To store a setting: 1. Set the machine to the desired setting. For example, press the OUT 3 button and IN 4 button1. 2. Press the STO button. The STO button flashes. 3.
Operating the VS-88H 8x8 HDMI Matrix Switcher 7.5 Controlling via ETHERNET You can connect the VS-88H via the Ethernet, using a crossover cable (see section 7.5.1) for direct connection to the PC or a straight through cable (see section 7.5.2) for connection via a network hub or network router 1. 7.5.1 Connecting the ETHERNET Port directly to a PC (Crossover Cable) You can connect the Ethernet port of the VS-88H to the Ethernet port on your PC, via a crossover cable with RJ-45 connectors.
Technical Specifications 6. Select Use the following IP Address, and fill in the details as shown in Figure 4. 7. Click OK. Figure 4: Internet Protocol (TCP/IP) Properties Window 7.5.2 Connecting the ETHERNET Port via a Network Hub (StraightThrough Cable) You can connect the Ethernet port of the VS-88H to the Ethernet port on a network hub or network router, via a straight through cable with RJ-45 connectors.
Communication Parameters 9 Communication Parameters Table 3: Communication Parameters RS-232 Protocol 2000 Baud Rate: 9600 Data Bits: 8 Stop Bits: 1 Parity: None Command Format: HEX Example (Output 1 to Input 1): 0x01, 0x81, 0x81, 0x81 Ethernet Default Settings Reset Ethernet Default Settings IP Address: 192.168.1.39 Power cycle the unit while holding in the Factory Reset button, located on the rear panel of the unit.
Kramer Protocol 2000 10 Kramer Protocol 2000 The VS-88H is compatible with Kramer’s Protocol 2000 1 (version 0.50) (below). This RS-232/RS-485 communication protocol uses four bytes of information as defined below. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.
Kramer Protocol 2000 Table 5: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.
Kramer Protocol 2000 NOTE 13 - This is a request to identify the switcher/s in the system. If the OUTPUT is set as 0, and the INPUT is set as 1, 2, 5 or 7, the machine will send its name. The reply is the decimal value of the INPUT and OUTPUT. For example, for a 2216, the reply to the request to send the audio machine name would be (HEX codes): 7D 96 90 81 (i.e. 128dec+ 22dec for 2nd byte, and 128dec+ 16dec for 3rd byte).
