Stacking (Daisy-Chaining) of Multiple MC4-H2 or MC4-H2-SW Units
In order to connect two or more units to expand the number of PC’s that you control, you need to order a Daisy-Chain Cable Set.
Connect the OUT of the Slave #1 to the IN of the Master. If you have a 2
nd slave connect the OUT of it to the IN of Slave #1. The
Power Supply connected to the master unit will power up the Slave Units through the expansion port. However there is no
damage if you connect supplies to the slaves and in fact it is recommended when you have 3 units.

Hot Swapping Mice and Keyboards
Hot swapping is not recommended but may be successfully performed. You may unplug the mouse and/or the keyboard
while the MC4-H2 or MC4-H2-SW is powered up and PC’s are connected and powered on. You may then plug in the
same keyboard/mouse or a different keyboard/mouse and the MC4-H2 or MC4-H2-SW will recognize the new
keyboard/mouse.
