Connect up to eight 2 HDMI sources (for example, DVD players) to the IN HDMI connectors. 2. Connect the four 3 OUT HDMI connectors to up to four HDMI acceptors (for example, LCD displays with built-in speakers). 3. If required, connect a PC/controller to the RS-232 port (see Section 7.
Operating the VS-84H 8x4 HDMI Matrix Switcher 7 Operating the VS-84H 8x4 HDMI Matrix Switcher This section describes: • Switching an input to an output (see Section 7.1) • Acquiring the EDID (see Section 7.2) • Storing and recalling switch settings (see Section 7.3) • Resetting the VS-84H (see Section 7.4) • Connecting to the VS-84H via RS-232 (see Section 7.5) • Connecting to the VS-84H via Ethernet (see Section 7.6) 7.
Operating the VS-84H 8x4 HDMI Matrix Switcher 7.2.2 Acquiring the EDID from Several Outputs To acquire the EDID from several outputs (for example, OUT 1 to IN 1 and OUT 4 to IN 3): 1. Connect the display devices to the outputs from which you want to acquire the EDIDs. 2. Press the EDID and STO buttons simultaneously and hold them for 3 seconds. Both buttons flash. 3. Press the input button to which the EDID will be copied (for example, IN 1). The selected input number flashes on the display. 4.
Operating the VS-84H 8x4 HDMI Matrix Switcher 7.3 Storing and Recalling a Switching Setting from a Preset The STO and RCL buttons are used to store and recall up to 12 setups which are assigned using the 4 output (preset 1 to 4) and 8 input (preset 5 to 12) buttons. To store a preset 1 (for example, Input 4/Output 3 in preset 10): 1. Configure the switching as required for the preset (for example, Input 4 to Output 3). 2. Press the STO button. The STO button flashes. 3.
Operating the VS-84H 8x4 HDMI Matrix Switcher 7.6 Connecting to the VS-84H 8x4 HDMI Matrix Switcher via Ethernet You can connect the VS-84H via the Ethernet, using a crossover cable (see Section 7.6.1) for direct connection to the PC or a straight through cable (see Section 7.6.2) for connection via a network hub or network router 1. 7.6.

Kramer Protocol 2000 12 Kramer Protocol 2000 The VS-84H is compatible with Kramer’s Protocol 2000 1 (version 0.50). This RS-232/RS-485 communication protocol uses four bytes of information as defined below.
Kramer Protocol 2000 For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1. Table 6: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.
Kramer Protocol 2000 NOTE 8 - The reply is as in TYPE 3 above, except that here the OUTPUT is assigned with the value 0 if the setup is not defined / no valid input is detected; or 1 if it is defined / valid input is detected. 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.
