1 Front Panel
IR Sensor
This IR sensor receives signals from the included IR remote control unit.
HDMI Input Selection Buttons
These illuminated buttons are used to select which of the four HDMI Inputs are to be routed to the HDMI
Output. Both video and embedded audio will be routed. The selected button will illuminate blue while
all other input buttons will be off. Flashing LED behaviors may occur for alert and diagnostic purposes.
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 the Ethernet port will still be active to wake up the SW-41Plus.

2 Rear Panel
HDMI Inputs
Connect the video sources to any of the four HDMI inputs, which corresponds to the HDMI Selection
buttons 1-4 located in the front. Input #1 supports Audio Return Channel (ARC), and by default, should
be connected to an ARC capable Audio/Video Receiver (AVR) or Soundbar.
Note: Zigen highly recommends the use of premium 4K certified HDMI cables when viewing UHD 60p
4:4:4 or UHD 60p HDR 4:2:2 video resolutions. Zigen offers these premium 4K certified cables in varying
lengths from 3 meters to 9 meters.
HDMI Output
Connect a display to this HDMI Output. One of the selected inputs will route video and embedded audio
to this output. If ARC is enabled, audio sent to the display from the selected HDMI Input or audio sourced
from the display (SmartTV Apps) will be passed through to HDMI input #1 if an ARC capable Audio/Video
Receiver (AVR) or Soundbar is connected.
SPDIF (TOSLINK) Output
This SPDIF (TOSLINK) optical port will output the embedded audio either from the selected HDMI Inputs
or from HDMI Out ARC depending on the audio source selection from the ZigNet Web Interface. The
SPDIF output supports 2-Channel PCM as well as surround sound formats like Dolby Digital and DTS.
Unbalanced Analog Audio RCA Outputs
The RCA Left/Right connectors will output analog audio either from the selected HDMI Inputs or from
HDMI Out ARC depending on the audio source selection from the ZigNet Web Interface. Only 2-Channel
Stereo audio format is supported. Noise will be heard on the RCA Outputs if a surround sound audio
format, such as 5.1, 7.1, Dolby Digital, DTS, etc., is configured.
RS-232 Connection
An RS-232 connection is typically connected to a 3rd party Control System to configure the SW-41Plus.
Communication through the RS-232 port is enabled in both Active and Standby Modes.

Baud Rate: 115,200
Data Bits: 8
Stop Bits: 1
Parity: None
Flow Control: None
For information on the RS-232 control port, refer to section 10 RS-232.
IR Input Connection
The IR Input Plug can be connected to an IR Receiver (3-pin Jack, 5V) or 3rd party Control Systems (2-pin
Jack). The pin out for the IR connectors are as follows:
Refer to section 13 Infrared (IR) Protocol for a list of available IR command protocols used to control the
SW41Plus.
Ethernet LAN Port
The Ethernet LAN port is a 100 Base-T connection to any router, switch, or directly to a computer. The
SW-41Plus features a web interface, called ZigNet. Hardware configuration, EDID management, and
advanced diagnostics can all be accessed through ZigNet.
The Ethernet LAN also feature HTTP or Curl protocol to allow 3rd party Control Systems with appropriate
drivers to control the SW41Plus. Refer to section 12 Application Program Interface (API) for more
information.
Power
The SW-41Plus requires 12VDC @ 1Amp to power the unit. Use the included power adaptor and ensure
the locking ring is threaded snugly to prevent inadvertent disconnection of the power jack. Make sure
all video, audio, and control ports are properly connected before applying power to the SW-41Plus.

4 Installation
Video
1. Use HDMI cables to connect UltraHD sources to the Inputs on the back panel of the unit.
2. Use an HDMI cable to connect a display to the Output on the back panel of the unit.
The HDMI cable can then be connected in any of the following ways:
 Connect the HDMI cable to an Ultra HD display.
 Connect the HDMI cable to another Zigen switch or splitter, for cascading purposes.
Note: Zigen highly recommends the use of premium 4K certified HDMI cables when
viewing UHD 60p 4:4:4 or UHD 60p HDR 4:2:2 video resolutions. Zigen offers these
premium 4K certified cables in varying lengths from 3 meters to 9 meters.
Power
3. Connect the included 12V DC locking power supply to the 12V DC power receptacle on the rear
panel of the switch.
4. Connect the power supply to an electrical outlet.
IMPORTANT: Ensure that all video, audio, and control port interconnects are properly
connected before applying power to the unit. Failure to do so could cause irreparable
damage to the unit or cause injury to installers and end-users.
5 ARC Support
Audio Return Channel (ARC) is a feature where a display can send audio back to an Audio/Video Receiver
(AVR) or Soundbar using the display’s existing HDMI cable. Any HDMI cable can be used to transmit ARC
and no additional audio cables, such as TOSLINK or RCA, are required. Audio to be sent through the ARC
channel can be sourced from the display’s numerous HDMI Inputs or, in the case of a SmartTV, built-in
Apps such as Netflix®, or YouTube®.
For ARC to function properly, the AVR or Soundbar and the display must be capable of supporting ARC.
The ARC capable AVR or Soundbar must be connected to HDMI Input #1 only. The SW41Plus must be
configured to source audio from ARC using the ZigNet Web Interface.

to route to the device output.
1. When the SW-41Plus is powered-on for the first time, Input 1 will automatically be selected.
2. Under normal conditions, the four input selector buttons will illuminate blue when the
corresponding input is selected. However, all input selectors will flash simultaneously if a fault
condition is detected.
3. The button labeled Power will illuminate blue when pressed after connecting power to the unit.
Pressing the button again will put the unit in Standby and the button will illuminate red.
4. If Auto Switching is enabled from ZigNet and the currently selected HDMI input source is turned
off or disconnected, then the unit will automatically switch to the next available input.
