PANEL DESCRIPTIONS
1 Front Panel USB
These connectors provide easy access to USB connections of PC1 and PC2 independently
of the changeover system. These ports are available at all times and connect through
the GPI/MIDI connection on the rear panel (21 and 21). Please note that these ports are
USB1.1 compliant only (12Mbps)
2 MIDI Present indicator
This indicator will illuminate when a midi message is sent to the midi output of the
changeover unit
3 GPI Indicators
These indicators will illuminate when a GPI is activated. GO, STOP, PREVIOUS and NEXT
are accessed from the joystick port, GPI 1-8 from the GPI port on the rear of the unit.
4 PC2 (Master Changeover)
Activating this button will result in the unit changing all connections from PC1 to PC2.
When this button is illuminated PC2 is selected. This button changes over KVM, MIDI in
and out and GPI connections. (Subject to status of buttons5 & 6 see below)
5 Independent Data Changeover
This button allows the changeover of MIDI in and out and GPI control without switching
the KVM facilities. When illuminated MIDI and GPI control are active from PC2. This
button operates in conjunction with the PC2 Master Changeover button (4).
6 Independent KVM Changeover
This button allows the changeover of Keyboard, Video Displays and Mouse without
switching the MIDI and GPI facilities. When illuminated KVM is active from PC2. This
button operates in conjunction with the PC2 Master Changeover button (4).

IMPORTANT NOTE:
The Master changeover operates in conjunction with both KVM and DATA
changeover buttons from their current state. Hence when the Master changeover
button is activated both KVM and DATA changeovers change state from their
current position. Because of this it is possible to get out of sync if operating the
unit remotely. Users should make sure before a show that when the PC2 button is
pressed both DATA and KVM buttons are illuminated.
7. Status Display Indicator
This LCD display provides information as to the outputs and health status of the XUSB-
2. Each time an input contact is activated the display registers the MIDI event
generated. The display will also indicate PSU faults and default MIDI channel
assignment.
8 Mains IEC connection
The XUSB-2 requires 110Vac – 240Vac at 50Hz main supply.
9 Remote Connector
This four pin XLR connector allows for remote changeover of the system and an
additional latching relay output for changeover of further connected units.
Pins 1 & 2 provide a momentary contact allowing changeover of the PC2 master
changeover function.
Pins 3 & 4 provide a latching relay output which is closed when PC2 master
changeover is activated.
10 VIDEO output A & B
These 15pin VGA connectors provide dual head VGA outputs from the KVM switch.
11 VIDEO inputs 1A&B and 2A&B
These 15pin VGA connectors provide dual head VGA inputs to the KVM switch. VGA
from PC1 should be connected to 1A and 1B. PC2 connected to 2A and 2B.
12 USB Console Connectors
These connectors allow connection of a USB mouse and Keyboard that will be switched
between PC1 and PC2. Other USB devices may work but are not supported at this time.
13/14 Keyboard & Mouse USB Connections
These connections should be made to PC1 and PC2 respectively. They facilitated the
keyboard and mouse control of both PC’s. DATA control is transported by an additional
USB cable and connected to the DATA/GPI ports (20/21).
15 GPI Connector
This connector allows for additional General Purpose inputs that can be used to control
additional effects. The connector is wired to allow use of standard Analogue Audio
Dtype cables.

17 MIDI link Indicator
When illuminated activated any midi messages received at the MIDI IN connector to be
passed to the MIDI in of both PC1 and PC2 regardless of Master Changeover Switch.
This facility allows for pseudo tracking via MIDI. See 19 for more details.
18 GPI Link Indicator
When illuminated any GPI messages received by the unit connector to be passed to both
PC1 and PC2 regardless of Master Changeover Switch. This facility allows for pseudo
tracking via GPI. See 19 for more details.

By Default the XUSB-2 is pre-programmed with MIDI note messages on the default
MIDI channel set by the above switches. These can be modified by MIDI sysex using an
application provided. (Windows PC and MIDI interface required)
20/21 GPI & MIDI USB Connections
These connections should be made to PC1 and PC2 respectively. They facilitated the
MIDI and GPI control of both PC’s. KVM control is transported by an additional USB
cable and connected to the Keyboard/Mouse ports (13/14).
22 MIDI IN Connector
This connector allows for MIDI to be input to either or both PC’s as explained above.
23 MIDI OUTPUTS
The XUSB-2 incorporates a 1 in four out MIDI Thru box permanently attached to the
output of the actively selected PC. All outputs are opto-isolated and switch from PC1
output to PC2 output with DATA switching as outlined above.
