1. Introduction
1.1 Introduction to PT-PSW-21
The PT-PSW-21 is a professional 4K Scaler Switcher that scales HDMI/VGA video
signal to an HDBaseT output by selecting output resolution from 720p to 4K via OSD.
The HDBaseT output supports bidirectional PoH and can connect to HDBaseT receiver
up to a maximum of 70 meters (230 ft) (HDBaseT receiver sold separately).
With 1 IR In and 1 IR Out and 1 RS232, the IR and RS232 control signals can be
transmitted bi-directionally between the PT-PSW-21 and a compatible HDBaseT
receiver. It also works with the HDMI and VGA table grommets to switch source and
output black screen for display (table grommets sold separately).
The PT-PSW-21 supports advanced built-in EDID management and is HDCP 2.2
compliant. Video and audio sources can be selected via front panel button, table
grommets or RS232 commands by 3rd Party control device. Moreover, it features
volume buttons to turn up/down the volume level.
1.2 Feature
Features 1 HDMI input and 1 VGA input with auxiliary audio input.
The output resolution can be selected from 720p to 4k x 2k @30Hz 4:4:4 to
assure preferred output.
Transmits 4Kx2K up to 131ft (40m) or 1080p up to 230ft (70m) via HDBaseT port.
Supports volume control via buttons.
Supports HDMI/VGA table grommets to control source switching and black screen
showing.
Automatically switch based on video sensing.
Supports RS232 pass-through to communicate control signal between the scaler
and the connected HDBaseT matrix or receiver.

4. Button Control
Front panel buttons can be used for video switching, volume adjusting and output
resolution selection.
4.1 Signal Switching
①Manual Switching
Press the SORCE/AUTO-3s button to select the HDMI or VGA source, the
corresponding green activity LED (HDMI/VGA) will be lighted up.
②Auto Switching
Long-press the SORCE/AUTO-3s button at least 3 seconds to enable auto switching
mode, the green activity LED (AUTO) will be lighted up. Press this button again to
select next source and exit auto mode.
The auto switching mode abides by the following principles:
New Input
Once new source is connected, the new source will be automatically switched to
input signal.
Rebooting Device
PT-PSW-21 has the ability to save the last configuration before losing power. The
switcher automatically enters the mode as last mode used; moreover, it detects all
the inputs and memorizes the connection status for future rebooting using. If the last
displayed signal is still available, the unit will output the signal. Otherwise, the unit
will detect all the input signals wit priority from HDMI to VGA. When the first signal
was detected, it will transfer to output.
Signal Removing
Once removing the current display signal, PT-PSW-21 will detect all input signals with
priority from HDMI to VGA. It will transfer the signal firstly detected to be available to
output device.

5. RS232 Control
Connect the control device (PC) to the RS232 port of PT-PSW-21, The PT-PSW-21 can
be controlled by sending RS232 commands via RS232 control software installed in
PC.
The RS232 port supports pass-through function, in additional, RS232 commands can
be transmitted bi-directionally between PT-PSW-21 and HDBaseT receiver, so it is
able to control a third party device from local or remote. The baud rate supports 2400,
4800, 9600(default), 19200, 38400, 57600 or 115200.
5.1 RS232 Control Software
Installation: Copy the control software file to the computer connected with
PT-PSW-21.
Uninstallation: Delete all the control software files in corresponding file path.
Basic Settings:
First to connect PT-PSW-21 with all input devices and output devices needed, then to
connect it with a computer which is installed with RS232 control software. Finally,
