SW-42Plus User Manual
1Introduction
The SW-42Plus is an HDMI 2.0 Audio/Video 4x2 Matrix Switch. The device has four HDMI inputs, two
HDMI outputs, two SPDIF outputs, and two Analog Audio Left/Right Balanced/Unbalanced outputs. Each
HDMI video output can be connected to any HDMI video input. Audio outputs 1 and 2 mirror the
embedded audio of HDMI outputs 1 and 2.
Both HDMI outputs have automatic down scalers for mixed resolution display environments. For
example, HDMI output #1 is connected to a native UHD display and HDMI output #2 is connected to a
1080p Display. If both outputs select the same source input with UHD resolution, then output #1 will
send the native UHD resolution video to the UHD display while output #2 will automatically downscale
the video for the 1080p display. This ensures compatibility by displaying the same source with different
resolution displays, while maintaining the highest quality native resolution for the UHD display.
Audio can be extracted from the connected HDMI inputs or from Audio Return Channel (ARC) on HDMI
Output #2. Table 1 shows where the extracted audio can be heard. Extracted ARC from HDMI output
#1 can be directed to HDMI input #1 if an ARC enabled Audio/Video Receiver (AVR) is connected to HDMI
input #1. Refer to Figure 3: Typical Interconnect Diagram. ARC can also be decoded and re-embedded
to HDMI Output #2, SPDIF Outputs, or Analog Audio Outputs (2-channels only).
Table 1: Audio Source to Audio Output support.
Source of Extracted Audio
Audio Outputs
HDMI Input
•Analog Audio Output 1 or 2 (2-Channel PCM Stereo Only)
•TOSLINK 1 or 2 (Multi-Channel Dolby/DTS Surround Sound)
•HDMI Output 1
•HDMI Output 2
ARC (HDMI Output 1)
•Analog Audio Output 1 or 2 (2-Channel PCM Stereo Only)
•TOSLINK 1 or 2 (Multi-Channel Dolby/DTS Surround Sound)
•HDMI Input 1 (Multi-Channel Dolby/DTS Surround Sound)
•HDMI Output 2
The SW-42Plus can negotiate with a Smart TV connected to HDMI Output #1 to enable ARC audio even
if there is no ARC supported AVR or a SoundBar connected in the system. This extracted ARC can be
directed to the SPDIF outputs, Analog Audio Outputs, and HDMI Output #2.
The SW-42Plus includes an IR Remote Control for configuring the video matrix connections between
inputs and outputs. The unit can also be controlled by 3rd party Control Systems (appropriate drivers
required) through control ports such as IR Port (3.5mm Jack), RS-232 (DB9), and Ethernet LAN.
The SW-42Plus is featured with a webGUI interface called ZigNet. With ZigNet, the user has full control
of Audio/Video Switching, Analog Audio Processing, Source and Sink Diagnostics, and EDID Reporting.
ZigNet eliminates the need for costly analyzers and time-consuming step by step troubleshooting.

2Front Panel
IR Sensor
This IR sensor receives signals from the included IR Remote Control unit. Aim the IR Remote Control in
this window while pressing its buttons.
HDMI Input Selection Buttons
These illuminated buttons are used to select which of the four HDMI Inputs are to be routed to the HDMI
Outputs. Both video and embedded audio will be routed. If the buttons are illuminated blue, then
Output #1 will be connected to the selected HDMI Input. If the buttons are illuminated red, then Output
#2 will be connected to the selected HDMI Input. The selected HDMI input button will illuminate while
all other input buttons will be off. Flashing LED behaviors may occur for alert and diagnostic purposes.
Output Button
The Output button selects which of the two HDMI Outputs will be configured. Pressing the Output
button will toggle its illumination between blue and red. If the Output button is illuminated blue, then
HDMI Output #1 will be connected to the selected HDMI input. Conversely, red illumination will
configure HDMI Output #2 to the selected HDMI input.
Power Button
Pressing this illuminated button will toggle between Active Mode (Blue) and low power Stand-By Mode
(Red) when power is applied from the included 12V DC power supply connected to an electrical outlet.
In Stand-By Mode, no video will be present at the output and the audio will be muted. However,
administration through Ethernet and RS-232 ports will still be active to wake up the SW-42Plus.
