suitable USB devices (such as a mouse or keyboard) to any of the USB Type A Device Hubs
ports (outputs).
NOTES:
•
There are 3 USB hubs in series within the USB boards. Per USB specifications,
up to 5 USB hubs can be used in a system.

Features of SMX USB boards:
Peripheral emulation
— Constantly emulates an HID (Human Interface Device) compliant
mouse and keyboard to any connected host without necessitating any ties to an output
device. This feature facilitates a problem-free boot up and is evident in the device manager
of the host PC as it constantly reports a mouse and keyboard are connected to it.
Host emulation
— Emulates a host to multiple standard keyboards and mice. Connected
keyboards and mice operate as one unit.
The default setting for host emulation is Off. To enable or disable host emulation (see the
USB Board SIS commands
on page 52 or
USB Settings/Status
on page 67).
NOTES:
•
When host emulation is enabled, Device Hubs ports continually provide power
to attached peripherals. However, they will not be functional until ties are
made to a host.
•
Host emulation is valid through a hub or USB extender.
•
If non-HID devices are connected to the Device Hubs ports, host emulation is
disabled.
Hot key switching
— Routes or makes a tie between a specific input using a specific
combination of key presses on an attached keyboard and an output. To make a tie, press
Ctrl + Shift + <
desired input to be tied>
.
NOTES:
Hot key switching can be executed only under the following conditions:
•
Host emulation is enabled for the desired output.
•
The output has a “standard” keyboard (it cannot require special USB drivers) to
execute the button combination for hot key switching.
KVM application
— The USB and video board must be set to the same plane address in
order to switch the keyboard, video, and mouse together during ties.
SMX Frame and I/O Board Installation
If the SMX is to be rack mounted, it is important to mount it before cabling it (see
Mounting the Switcher
on page 125).
Installing the I/O Boards
The I/O boards on any unit may vary with each installation, depending on desired
configuration and use. Each board has input and output connectors that are clearly marked,
and a 16-position rotary switch used to set the I/O plane address.
