1. Intro
The KanexPro HDSC61D-4K is a six input to one output 4K/60Hz collaboration
switcher consisting of 3-HDMI, one USB-C, one DisplayPort and one VGA input to one
HDMI output. These inputs can be switched from various HDMI, USB-C based laptops,
iPads and other computing devices to one 4Kx2K display offering HDR, 4:4:4 sampling.
Multi-channel Audio and De-embedding
The switcher supports stereo and multichannel audio on the HDMI inputs. HDMI output
stream provides audio de-embedding via phoenix connectors and optical port, the
audio is simultaneously de-embedded to an optical digital audio output and a balanced
analog audio output.
Auto-Switching & Control
Multiple methods of control are available with this unit by pressing the “Auto” button for
3 seconds, the unit will automatically switch to the first detected source device. When
the active source is removed, the switcher will switch from input 1 to 6. The switcher
can be paired virtually with any 3rd party control system using RS-232 drivers or
controllable by front-panel buttons or IR remote control inclusive.
Applications:
Designed for classrooms, conference rooms, huddle rooms and other collaboration
spaces where digital and analog sources need to be switched and scaled in a fast and
reliable manner.
Note: The scaling function will only work on VGA source devices from the input side
and will not handle any upscaling from HDMI/DVI inputs.

5.1 Manual Switching
When the switcher is in the manual switching mode, the Auto Mode LED goes out. If
need to change the input source, please directly press the 1, 2, 3, 4, 5 or 6 button, and
the corresponding LED illuminates green immediately.
5.2 Automatic Switching
Press and hold the AUTO button at least three seconds to enable automatic switching,
and the Auto mode LED will light.
When in the Auto mode, the switcher will switch according to the following rules:
⚫The switcher will switch to the first available active input starting at input 1 to 6.
⚫New input: The switcher will automatically select the new input once detecting a
new input.
⚫Reboot: If power is restored to the switcher, it will automatically reconnect the input
before powered off.
⚫Source removed: When an active source is removed, the switcher will switch to the
first available active input starting at 1-HDMI/MHL input.
⚫Press the Video Source button (1, 2, 3, 4, 5 or 6) can directly change the input
source. If the corresponding source device is active, it will be switched as input
source; otherwise, the switcher will switch to the first available active input starting
at 1-HDMI/MHL input.
⚫Press and hold the AUTO button at least three seconds again can exit AUTO mode,
but the input source will remain the current setting.
5.3 Display Control

5.4 VGA Resolution Selection
The RES button on the front panel is designed for VGA resolution selection.
OFF: Display Off.
Press RES button repeatedly to set the VGA resolution to 1280x720, 1920x1080 or
1920x1200, and its corresponding LED will illuminates green.
5.5 EDID Setting
The Extended Display Identification Data (EDID) is used for the source device to match
its video resolution with the connected display. By default, the source device obtains its
EDID from the first connected display. Meanwhile, since the displays with different
capabilities are connected to the switcher, the 4-pin DIP switch on the rear panel can
be used to set the EDID to a built-in fixed value. Use the following table to determine
the setting for the 4-pin DIP switch for specific video resolution and audio capabilities.
The switch represents “0” when in the lower (OFF) position, and it represents “1” while
putting the switch in the upper (ON) position.
