Introducing the PS190 - 5 X 1 HDMI Auto-Switcher
with Integrated Audio Mixer, Injector, & Stereo Output
The PS190 allows 5 HDMI sources to share one display or projector with resolu ons up to
UHDTV (3840x2160). The 3.5mm stereo input port allows line level microphone or mobile
device to be mixed with audio extracted from the selected HDMI input then re-injected into the
HDMI stream. An RCA stereo output provides a pre-ampli ed output for local speakers if the
volume from the display is inadequate or if ADA assisted listening equipment is required. The
system’s auto-sense, auto-switch feature combined with the automa c integrated display power
on and o makes this solu on extremely easy to use. For installs that require Crestron, AMX, or
other 3rd party control systems, an RS-232 connector is provided for power, source selec on,
and volume control.

Installation
Connecting Input Devices
Input or source devices are connected on the back side of the PS190 using the HDMI connectors
labeled “Input 1” through “Input 5”. See image call-out on Page 4 of this manual.
Compable Input Devices
PS190 compable devices must support the HDMI signal format. These physical devices may be
any of the following:
• A nave HDMI device
• A DVI-D or DVI-I device using a DVI to HDMI cable
• A DisplayPort device using a DisplayPort to HDMI cable
• A MDL mobile device using a MDL to HDMI cable
The PS190 also supports indirect connecons. The input device may be connected to a
connecvity box such as Extron® Cable Cubby™ or Alnex® Tilt ‘N Plug™ rst before being
connected to the PS190.
HDMI Extenders
The input may also be indirectly connected using an HDMI extender. By default, the PS190 keeps
its display informaon (EDID) local to each input. There is very lile delay from the me an input
device asks for the display informaon to the me the informaon is sent. A device connected
to an extender may “me-out” waing for a response from the display device. If a me-out
occurs, the input device will not send its content. It is important to use high quality extenders so
any delay caused by the extender technology is minimized and me-outs are less likely to occur.
The PS190 has a “pass through” mode that passes all display informaon requests directly to
the display. If this feature is enabled and the system is congured with extenders on the input
and output ports of the PS190 it is possible to have me-outs on certain input devices.

Connecting the Display
Displays (or other output devices) are connected on front side of the PS190 on the HDMI
connector labeled “Video Output”. See image call-out on Page 4 of this manual.
Compable Displays
PS190 is compable with nave HDMI, DVI, or DisplayPort displays.
Image Resoluons
The PS190 supports resoluons up to UHDTV (3840 x 2160 @ 30Hz [4:2:2] or 60Hz [4:2:0]), all
HDTV resoluons, and VESA monitor resoluons up to 1920 x 1200.
Stereo Audio (Line) Input
Connect the audio from a mobile device or wireless microphone system (line level) to the
3.5mm stereo jack of the PS190. See image call-out on Page 4, “Stereo In”.
The audio from this connector is automacally mixed and sent to the HDMI display and stereo
output. Gain adjustments are available through the RS-232 interface.
Stereo Audio Output
If external speakers are required, connect an RCA cable from the PS190 “Stereo Out” connectors
to your amplier or powered speakers. See image call-out on Page 4, “Stereo In”.
The stereo output is a mix of program audio (audio extracted from the selected HDMI input)
and stereo audio line input (3.5mm jack). The default mix and level should be adequate for most
installaons. However, gain and volume level adjustments are available through the RS-232
interface.

RS-232 Communication Interface
The PS190 uses an RS-232 serial interface to change aributes and behavior of the PS190. The
communicaon parameters are as follows: 115200 baud, 8 bit, no parity, and 1 stop bit. The
baud rate is xed and unchangeable. Pins 2 (Rx), 3 (Tx), and 5 (GND) are used.

Power
Using the AC to DC power supply shipped with the PS190, connect the round connector to the
PS190. The Power Indicator LED will illuminate above of the DC/5V locaon to indicate that
power is being received.

Page 8 Presentation Switchers, Inc.
Basic Operation
In most situaons, the PS190 performs exceponally right out of the box. Simply hook up the
input devices and display in any order, power up the system. The PS190 will begin in an auto-
sense, auto-switching mode with audio output and display control enabled. Keep in mind that
features can be turned on and o using the RS-232 interface. See Page 10 for more informaon.
Two key features of the PS190 are related to automaon: auto-switching and display
management.
Auto-Sense, Auto-Switching
Auto-sense, automac switching (ASW) is a very powerful feature of the PS190 and will be
explained further to best understand how it can be ulized. ASW is enabled by default and can
be disabled using the RS-232 interface.
The PS190 is very sensive. When a user connects a device to one of the 5 HDMI input ports,
the PS190 responds immediately by roung the video from the newly connected device to the
display. If the color space is dierent than the display, color is automacally converted internally
to ensure the highest quality image is displayed at the highest resoluon praccable.
If another person connects a computer or mobile device to an HDMI input port, that device will
immediately appear on the display. The rule is: The last to connect will always appear on the
display.
Should an acvely displayed device be disconnected, the PS190 will search from input 1 through
input 5 for the rst acve signal. Once found, the image from that device will appear on the
display. From a design standpoint, consider having the home room computer on input 1 and any
ancillary or guest connecons on inputs 2 through 5.
Automatic Display On/O
Automac display on/o (CEC) is another powerful feature of the PS190. CEC is enabled by
default but can be disabled using the RS-232 interface.
CEC must be enabled on the display itself for this feature to work with the PS190.
Trade names for CEC are Anynet+ (Samsung), Aquos Link (Sharp), BRAVIA Link and BRAVIA
Sync (Sony), HDMI-CEC (Hitachi), E-link (AOC), Kuro Link (Pioneer), INlink (Insignia), CE-Link
and Regza Link (Toshiba), RIHD (Remote Interacve over HDMI) (Onkyo), RuncoLink (Runco
Internaonal), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic),
EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).

Page 9PS190 Users Guide
If a user connects to the PS190, the PS190 will automacally turn the display on. When the last
person disconnects, the PS190 will wait 30 seconds of inacvity then turn o the display. In
many cases, this feature eliminates the need for television remotes, extends display life, saves
power, and simplies classrooms, conference rooms, and huddle spaces, making them more
user friendly.

Changes to the PS190
The PS190’s RS-232 interface allows users and integrators the ability to control switching and
change the behavior of the PS190. This secon will describe the commands that are available
and detail their aect on the system.
