The SC-3H is a multi-format switcher with 2 HDMI and 1 VGA (with audio) inputs. The SC-3H provides an HDMI video output together with stereo analog audio output. HDMI inputs support virtually all PC and TV resolutions including 4K @ 30 and 4K @ 60 (4:2:0). The VGA and its associated audio inputs are converted to HDMI and scaled to 1080p for maximum compatibility with HDMI TV’s.
Affordably priced, the SC-3H provides a powerful and cost effective way to add AV switching and control to any classroom, huddle room, or conference room.
The device can manually or automatically switch between the various video inputs. In auto input mode it scans the inputs in order to detect video on its inputs and automatically switches to the active input. If more than one input has video, the SC-3H can choose among them based on user definable priority tree.
The device can also act as a controller to send serial RS232 commands to turn displays on and off. Users can upload power control commands for their display and when the SC-3H is turned on, it will send the ‘on command’ to the display and upon turning the device off, an off command will be issued. The power commands can also function automatically. In Auto Power Command Mode, the unit will send out a power on command if there is video on the output, and if there is no video is being output, it will send a power off command to the display after a predefined delay.
Normally the RS-232 port on the unit is acting as the ‘master’ issuing commands to external devices, but this port can also be used to control the SC-3H. Please see Section 5 of the Manual for details.
To use the unit in manual mode, where power and inputs are selected manually, front panel buttons can be used. Alternatively, an optional external single-gang wall-plate controller can be connected to the SC-3H. They are SW3-UI and SW3-UI-VOL.
Full EDID management is provided for the HDMI inputs. By default the connected display’s EDID is used for the HDMI inputs, but users have the ability to upload, emulate read, or download the EDID. A mini-USB port on the front panel is provided to configure the device via a free Windows™ GUI available from the Downloads tab on the product webpage.
