PRODUCT DESCRIPTION
FEATURES
PANEL DESCRIPTIONS
The HDBT-SCL21R/P is a professional 4K Scaler Receiver that scales HDMI/HDBaseT video signal
to a HDMI output by selecting output resolution from 720p to 4K. The HDBaseT input supports PoC
and can connect to HDBaseT transmitter up to a maximum of 100m.
With 1 IR In and 1 IR Out and 2 RS232 ports, the IR and RS232 control signals can be transmitted
bi-directionally between the HDBT-SCL21R/P and any compatible HDBaseT transmitter (such as
MAX-HDBT62/P).
The HDBT-SCL21R/P supports advanced built-in EDID and HDCP management. Video sources
can be selected via front panel button and RS232 commands by 3rd Party control device.
● Features 1 HDMI input and 1 HDBaseT input.
● The HDMI output resolution can be selected from 720p to 4Kx2K @60Hz 4:4:4 to
assure preferred output.
● HDMI signals transmission up to 70m at 4K and 100m at 1080p on HDBT input.
● Output resolutions selectable to assure preferred output, and supports various
output resolutions, such as 4Kx2K@60Hz, 4Kx2K@30Hz, 1920x1080p@60Hz,
1280x720@60Hz and so on.
● Supports RS232 pass-through to communicate control signal between the scaler and
the connected HDBaseT matrix.
● Controllable via RS232 local and pass-through, IR local and pass-through.
● The receiver can be powered by the connected HDBaseT matrix via PoC.
● Supports advanced built-in EDID management.

Signal Switching
Press the SWITCH button to toggle and select the HDMI or HDBT source, the corresponding blue
activity LED (HDMI/HDBT) of the selected input will light up.
Alternatively, source input can be selected via RS232 command. Please refer to page 5 (Signal
Switching) for more details.
Output Resolution List
There is a built-in scaler to up-scale or down-scale the input signal to a fixed output resolution. Ten
output resolution options can be selected for the HDMI output via RS232 command. Please refer to
page 5 (Output Resolution Selection) for more details.
The following table shows the list of available output resolution:

SYSTEM OPERATIONS
RS232 Control
The RS232 port of HDBT-SCL21R/P has two control methods.
1) Local control: Connect the RS232 (Control) port to a control device (e.g. PC) to control the unit
by RS232 commands.
2) Pass-through control: The RS232 (Passthrough) port is used with the RS232 port of far-end
HDBaseT transmitter to control the third-party device (e.g. Projector)
RS232 Command
The command lists are used to control the scaler receiver. The RS232 control software
(e.g. docklight) needs to be installed on the control PC to send RS232 commands.
After installing the RS232 control software, please set the parameters of the COM port, baud rate,
data bit, stop bit and the parity bit accordingly to ensure that the software is able to communicate
correctly with the device
Baud rate: 9600
Data bit: 8
Stop bit: 1
Parity bit: none
Note:
● All commands needs to end with “<CR><LF>”.
● In the commands, “[”and “]” are symbols for easy reading and do not need to be typed in actual operation.
● Type the command carefully, it is case-sensitive.
