SYSTEM CONNECTION
The following diagram illustrates typical input and output connections that can be utilized with the switcher:
Note: We recommend the use of CATx shielded cables in order to guarantee the performances declared in the HDbaseT protocol specs.
8.1 Source Switching
- Press the SOURCE AUTO button to switch to next source device, and then the corresponding input LED will turn green.
- Press and hold the SOURCE AUTO button at least 3 seconds to enable auto-switching mode.
For auto-switching mode, remember the following rules:
- The switcher will switch to the first available active input starting at HDMI IN 1> HDMI IN 2 > USB-C.
- New input: Once a new input signal is detected, the switcher will automatically switch to this new signal.
- Source removed: When an active source is removed, the switcher will switch to the first available active input starting at HDMI IN 1.
- Reboot: The switcher can save the last configuration before losing power. If the last switching mode is auto-switching, the switcher will automatically enter auto-switching mode once rebooted, then detect all inputs and memorize their connection status for future rebooting use. If the last selected input source is still available, the switcher will switch to this input. Otherwise, it will switch to the first available active input source starting at HDMI IN 1.
- Exit auto-switching mode: Press and hold the SOURCE AUTO button for 3 seconds to exit the auto mode, and the input source will not be changed.
8.2 Display Control
- Press the blue-backlight DISPLAY ON/OFF button to turn on/off the display by automatically sending CEC and RS-232 commands (Programming required). When sending the ON command, the button will turn blue; when sending the OFF command and the button will be not illuminated.
- The DISPLAY ON/OFF button also can be programmed by IR learning feature or RS232 command. For more details, please refer to the User-Defined Button.
RS-232 Control
9.1. RS-232 Connection
According to the RS-232 control mode, there are three types of RS-232 connections for different applications.
- To control the switcher from local, please connect a control device (e.g. PC) to the RS-232 port of the switcher.
- To control the switcher from the remote, please connect a control device (e.g. PC) to the RS-232 port of the remote receiver.
- To control the far-end third-party device, please connect the control device (e.g. PC) to the RS-232 port of the switcher, and then please connect the third-party device (e.g. projector) to the RS-232 port of the remote receiver.
9.2. RS-232 Control
After devices are connected accordingly to the RS-232 connection diagram, VEOXWT44E can be controlled by a PC (using serial terminal software) or by a third-party control system.
Please set the correct COM number on your PC or control system and baud rate, data bit, stop bit, and parity bit as follows:
Baud rate: 9600.
Data bit: 8.
Stop bit: 1.
Parity bit: none.
With these parameters, it will be possible to communicate with the VEO device and send the commands listed in the next chapter.
RS-232 COMMANDS
The following table lists all the commands available for the VEO-XWT44E.
