Front Panel Operation
The MPS switcher can be connected to as many as nine input devices and four output
displays plus an audio amplifier. It operates in one of four switching modes: single (the
default), separate, single-combine, or separate-combine.
The functions of the front panel controls are described in the following sections. Each input
group; VGA/YUV, DVI-D, HDMI, and composite, have one video and one audio output each.
The output is switchable only between the inputs of the corresponding group, except in
combine mode.
Although the wiring and connection of the switcher are identical, the four modes operate
differently.
Switcher Operating Modes
The switcher operating modes are:
• Single switcher (default) mode emulates one switcher with 9 inputs (9x1).
• Separate switcher mode allows the four groups of inputs (DVI, HDMI, VGA, Composite
video) to be used as individual switches, creating four independent switchers.
• Single-combine mode operates exactly as the normal single mode except the three
HDMI and two DVI inputs are output on the HDMI output.
• Separate-combine mode operates exactly as the normal separate mode except the three
HDMI and two DVI inputs are output on the HDMI output.
NOTE: The switcher does not convert signal formats between VGA and DVI/HDMI
nor will it scale or convert between other input formats.
View Mode
The current switcher mode can be determined by observing the input LEDs. If the unit is
in separate switcher mode, up to four input LEDs can be lit (one in each group). In single
switcher mode only one input LED at a time is lit.
To view the current switcher mode, press and hold the Mode button (VGA/YUV #1) for more
than 3 seconds.
