4. System Connection
4.1 Usage Precaution
Make sure all components and accessories are included before installation.
The system should be installed in a clean environment with proper temperature and
humidity.
All the power switches, plugs, sockets, and power cords should be insulated and
safe.
All devices should be connected before system powers on.
4.2 System Diagram
The following diagram illustrates an example of connections that can be utilized using
the EXT-H211L2-SRX-HDBT and transmitter EXT-H101L2-TX-HDBT.

5. Video-switching
5.1 Manual Switching
Press the button on the front panel to select HDBT IN or HDMI IN.
5.2 Auto Switching
Press and hold the button more than 3 seconds to enter or exit auto mode. The auto-
switching mode abides by the following principles:
1. Once detecting a new input signal, the unit would switch to this new signal
automatically.
2. The unit has power-off memory function. If the last switching mode is auto-switching,
once rebooted, the unit will automatically enter auto-switching mode. If the last
displayed signal is still available, the unit will output the signal. If not, the unit will detect
all the input signals with priority from HDBT IN to HDMI IN. When detection of the first
valid video signal, it will switch it to the output.
3. Once removing the current signal, the receiver will switch to the next active input.
4. 5V/TMDS detection (Default is TMDS detection, see section 7.2 Commands for more
information).
Note: Support switching the input by RS232 commands even there is no input signal,
but the front panel button can’t.
6. Output Resolution
The switch represents “0” when in the lower (Off) position, and it represents “1” while
putting the switch in the upper (On) position.

7. Device Control
7.1 RS232
Connect the RS232 port to control device (e.g. PC) with RS232 cable. The machine
can be controlled by sending RS232 commands.
The list of commands is used to control the machine. A RS232 control software (e.g.
Docklight) needs to be installed on the control PC in order to send RS232 commands.
After installing the RS232 control software, please set the parameters of COM port,
baud rate, data bit, stop bit and the parity bit correctly.
Communication protocol: RS232 Communication Protocol default values
Baud rate: 9600 Data bit: 8 Stop bit: 1 Parity bit: none
