“Connect Source Devices Here”, and the display at locaon, “Display Output”.
Stereo Audio Input. Connect the 3.5mm stereo jack from an iPhone/iPad or wireless
microphone system (line level) to the PS190. The audio from this connector is automacally
mixed and sent to the HDMI device and stereo output. Trim, gain, and mix adjustments are
available through the RS-232 interface.
Stereo Audio Output. If external speakers are required, connect the RCA jacks from the PS190
to your amplifier or powered speakers. Audio on the RCA jacks are always acve. Volume and
mix levels are available through the RS-232 interface.

RS-232 CommunicaƟon Interface. The PS190 uses a serial interface (RS-232) to change
aributes and behavior of the PS190. Parameters are as follows: 115200 baud, 8 bit, no parity,
and 1 stop bit. The baud rate is fixed and unchangeable. Pins 2 (Rx), 3 (Tx), and 5 (GND) are
used. See the PS190 Programming Guide for available commands.
Power. Connect the DC power supply to the locaon “DC/5V”. The Power Indicator LED will
illuminate above of the DC/5V locaon to indicate that power is being received.
Auto-Sense, Auto-Switching
Auto-Sense, Auto-Switching
Auto-sense, automac switching (ASW) is a very powerful feature of the PS190 but should be
explained to gain the best understanding of how it can be ulized. ASW is enabled by default
but can be disabled using the RS-232 interface.
The PS190 is very sensive. When one connects a device to one of the 5 HDMI input ports, the
PS190 responds immediately by roung the video from that device to the display. If the color
space is different the display, the color space is automacally converted internally to ensure the
highest quality image is displayed at the highest resoluon praccable.
If another person connects her computer or iPad to an HDMI input port that person’s device will
appear. The last to connect will always appear on the display.
Should a device that is acvely displayed be disconnected, the PS190 begins searching from
input 1 through input 5 for the next available input. Once an acve signal is found the image
from that device will appear on the display. Therefore, consider having the home room
computer on input 1 and any ancillary or guest connecons on inputs 2 through 5.
Automatic Display On/Off
Automatic Display On/Off
Automac display on/off(CEC) is another very powerful feature of the PS190 and should also be
explained to gain the best understanding of how it can be ulized. 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 Interacve over HDMI) (Onkyo), RuncoLink (Runco
Internaonal), SimpLink (LG), T-Link (ITT), HDAVI Control, EZ-Sync, VIERA Link (Panasonic),
EasyLink (Philips), and NetCommand for HDMI (Mitsubishi).
If one connects to the PS190 the PS190 will turn the display on. When the last person
disconnects, the PS190 will wait 30 seconds of inacvity then turn offthe display. In many cases,
this feature eliminates the need for remotes, extends display life, and saves on power. This
feature also simplifies conference rooms and huddle spaces making them more usable.
