Introduction

MC4-H2allows two monitors, 1 keyboard, and 1 mouse to control 4 different PC’s or servers. By chaining up to 3 MC4- H2’s, up to 12 PC’s can be controlled

General

The MC4-H2switches both video outputs to display the selected PC’s video outputs at full resolution using buffered and wideband video circuits. It also routes the signals from the mouse and keyboard to the selected pc, while, at the same time, emulating a keyboard and a mouse for the unselected PCs so that they can detect and communicate with a “virtual” mouse and keyboard in order for the PCs to operate normally.

Upon power up the MC4-H2will locate and identify the type of mouse plugged into the mouse port and initialize that mouse. The same will then be done for the keyboard.

The power supply included with the MC4-H2will power up to 3 MC4-H2units. Only 1 power supply is need to power 3 MC4-H2units.

There are 3 ways the MC4-H2can switch from one PC to another. The first is through the buttons located on the front panel of the MC4-H2. The second is through a hot-key sequence from the keyboard and the third is through RS-232 control.

The unit supports 2-button, 3-button, and scroll mice. 4-button mice and above are not supported.

When the MC4-H2is powered up or reset, the PC that was last selected will be selected by default.

There are two different types of LEDs on the front panel. When the LED labeled PWR is illuminated then the PC attached to that port is powered on. When the LED labeled SEL is illuminated, then the PC attached to that port is the selected PC. The selected PC is the PC currently being controlled by then keyboard and mouse.
