Overview 3 Overview The Kramer VM-28H 2 Input 1:8 HDMI Distributor and VM-216H 2 Input 1:16 HDMI Distributor are high quality distributors that accept one of two HDMI inputs and distribute the signal to four outputs, allowing one or more of the outputs to be connected to receiving devices, thus making them a versatile, reliable component in a video system. The VM-28H / VM-216H distributes signals having resolutions up to UXGA (1600x1200), including all HDTV formats.
Overview 3.1 About HDMI High-Definition Multimedia Interface (HDMI) is an uncompressed all-digital 1 audio/video interface, widely supported in the entertainment and home cinema industry. It delivers the highest high-definition image and sound quality.
Your VM-28H / VM-216H 3.2 Defining EDID The Extended Display Identification Data (EDID 1) is a data-structure, provided by a display, to describe its capabilities to an HDMI source. The EDID enables the VM-28H / VM-216H to “know” what kind of monitor is connected to the output. The EDID includes the manufacturer’s name, the product type, the timing data supported by the display, the display size, luminance data and (for digital displays only) the pixel mapping data. 3.

Your VM-28H / VM-216H 4.1 Using the IR Transmitter You can use the RC-IR2 IR transmitter to control the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver 1. The external IR receiver can be located 15 meters away from the machine. This distance can be extended to up to 60 meters when used with three extension cables 2.
Installing on a Rack 5 Installing on a Rack This section describes what to do before installing in a rack and how to rack mount. with the 3.5mm connector that fits into the REMOTE IR opening on the rear panel.
Using the VM-28H / VM-216H 6 Using the VM-28H / VM-216H This section describes how to: • Connect the VM-28H / VM-216H, see section 6.1 • Control the VM-28H / VM-216H via RS-232, see section 6.2 • Operate the VM-28H / VM-216H, see section 6.3 • Use the EDID button, see section 6.4 6.1 Connecting the VM-28H / VM-216H This section describes how to connect the: • VM-28H, see section 6.1.1 • VM-216H, see section 6.1.
Using the VM-28H / VM-216H 6.1.1 Connecting the VM-28H 2 Input 1:8 HDMI Distributor To connect the VM-28H, as the example in Figure 3 shows, do the following1: 1. Connect the HDMI OUTPUT connectors2 to up to 8 HDMI acceptors, using Kramer HDMI copper cables.
Using the VM-28H / VM-216H 6.1.2 Connecting the VM-216H 2 Input 1:16 HDMI Distributor To connect the VM-216H, as the example in Figure 4 shows, do the following 1: 1. Connect the HDMI OUTPUT connectors2 to up to 16 HDMI acceptors, using Kramer HDMI copper cables.
Using the VM-28H / VM-216H 6.2 Controlling via RS-232 (for example, using a PC) You can connect a PC (or other controller) to the VM-28H / VM-216H via the RS-232 port.
Using the VM-28H / VM-216H 6.4 Using the EDID Button Initially, the VM-28H / VM-216H operates with the factory default EDID. You can acquire the EDID from: • One Output (the selected output LED blinks) • The Default EDID (all the output LEDs blink) • Several Connected Outputs, the Auto-mix Mode 1 (the output LEDs blink in sequence) To cycle between the different modes (One Output, Default and Auto-mix), press the input button (IN 1 or IN 2) to which you want to read the EDID, as defined in Table 2.
Using the VM-28H / VM-216H 4. Press an input button (either IN 1 or IN 2) once 1. The selected input button illuminates. 5. Enter the One output mode as defined in Table 2 (with either IN 1 or IN 2). 6. Press that input button to set the appropriate OUTPUT STATUS LED. The OUTPUT STATUS LED blinks indicating that that output channel is selected. 7. Press the LOCK button to copy the EDID of the selected OUTPUT to the input.
Technical Specifications 5. Enter the Auto-mix mode as defined in Table 2 (with either IN 1 or IN 2). The OUTPUT STATUS LEDs blink in sequence. 6. Press the LOCK button to copy the EDID of the selected OUTPUT to the input. Note: to cancel the EDID modification, press the EDID button before pressing the LOCK button. While the EDID is being copied the EDID button blinks. The new EDID is copied, when the EDID button no longer blinks.
Communication Protocol 8 Communication Protocol The VM-28H/VM-216H is compatible with Kramer’s Protocol 2000 (version 0.48) (below). 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.
Communication Protocol Table 5: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.
