SYSTEM CONNECTION
Auto-trigger CEC
Both outputs can send power on or power off CEC commands to the TV automatically by
detecting source inputs. User can choose one output or both via RS232 command. Please refer
to page 19 (Set auto TV power command) for more details.
Power on Command
When the first source input is detected, the switcher will automatically send CEC command to
turn on the TV when the set auto TV power option is enable on the particular output.
Power off Command
When the last source input was removed, the switcher will automatically send CEC command
to turn off the TV when the set auto TV power option is enable on the particular output.
RS232 Control
The RS232 port of switcher has two control methods.
1) Local control: Connect the RS232 (Control) port to a control device (e.g. PC) to control the
switcher by RS232 commands.
2) Pass-through control: The RS232 (Passthrough) port is used with the RS232 port of far-end
HDBaseT receiver to control the third-party device (e.g. Projector).
RS232 commands can also be used to control the unit via TCP/IP on port 23.
RS232 Commands:
The command lists are used to control the switcher. 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 COM number,
baud rate, data bit, stop bit and the parity bit accordingly to ensure that 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.
