OVERVIEW

INTRODUCTION

The 4K60 HDMI Dual-Head KVM Switch – 4-Port is a dedicated multi-platform KVM switch capable of managing four dual-head 4K computers through a single KVM. Built with ultra-HD ready HDMI outputs, the KVM Switch offers full 4K emulation at 60 Hz directly from the device. Until now, HDMI switches lost emulated picture when disconnected from monitors, leading to confusion and disorganization upon reconnecting. With the 4K60 HDMI Dual-Head KVM Switch, full EDID-assisted HDMI video emulation ensures visual workspaces and screen resolutions are remembered.
The KVM Switch is HDCP compliant, supporting screen resolutions up to 4K Ultra-HD (3840 x 2160 @ 60 Hz) with responsive EDID emulation. Additionally, the KVM Switch is compatible with any USB peripheral.
The KVM Switch is also easy to control with both a simple front-panel interface, as well as RS-232 or hot-keys.

• Source switching made easy: The KVM Switch offers simplified management between four dual-head HDMI equipped computers’ USB 2.0 outputs. Keyboards, mice, and other connected USB devices can be switched between with ease. This dynamic KVM switch can be controlled via hot keys or RS-232 commands, as well as directly through the console’s easy-to-read front panel.
• EDID passthrough and recognition: The KVM Switch features EDID passthrough technology and source recognition, which enable smooth and efficient switching in virtually any scenario. This plug-and-play EDID functionality makes set up hassle-free and simple.
• Full USB keyboard and mouse emulation: The USB keyboard and mouse emulation used by the KVM Switch provides quick source switching via keyboard hotkeys. The KVM Switch simulates the presence of a keyboard and mouse for every attached computer. This essential function simulates keyboard and mouse control for all connected computers, so switching between each is kept seamless and completely uninterrupted.

HOTKEY COMMANDS

A hotkey command is a keyboard sequence used to trigger an action on the KVM Switch through the use of the keyboard connected on the USB port of the KVM Switch. To activate the hotkey sequence, press the CTRL key twice and then enter the desired hotkey commands. See Table 5-1.

TABLE 5-1. COMMANDS

RS-232 CONTROL

Controlling the KVM Switch via RS-232 requires an RS-232 card installed on your computer or a USB to RS-232 adapter.
Check the KVM Switch and your computer to determine if you need a male-to-male or a male-to-female cable and how long it needs to be. The KVM Switch requires a straight-through cable. You can use a null-modem adapter to convert a crossed cable to a straight-through cable. An example of a straight through cable pinout is shown in Figure 6-1. The standard maximum length for an RS-232 cable is 50 feet (15.2 meters). Contact Black Box Technical Support at 877-877-2269 or info@blackbox.com if you require more information .

You will need to identify the COM port number used. On a Windows PC:

1. Click on the start button.
2. Click on Control Panel.
3. Click on Device Manager.
4. Click on the arrow next to Ports (COM & LPT). You should see the COM port number in use.

Run the terminal client of your choice such as HyperTerminal or PuTTY. Select the correct COM port on the computer. Use the following connection settings: 9600, N, 8, 1, no flow control.
Cycling power on your unit will display a boot up message in your terminal software if the connection is correct.
NOTE: Your terminal software may not default to or display all of the settings above. If you attempt to connect and the settings above are not set correctly, after you set them correctly you may need to cycle power on your unit for communication to be established.
See Table 5-1 for a list of RS‐232 commands.
