System Connection 4.1 Usage Precaution  Verify all components and accessories included before installation.  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 power on. 4.2 System Diagram

10 5. Display Control 5.1 Button Control Transmitter front panel buttons can be used for signal switching, display control. 5.1.1 Manual Switching Press any one of input sources and the corresponding input LED illuminates green, then press HDMI or HDBT output and the corresponding output LED illuminates green, after that, press SWITCH button to finish and confirm video switching, and input and output LED go out. 5.1.2 Auto Switching  Default Auto-Switching mode.  Four input sources priority: 1 HDMI>2 HDMI>3.DP>4.USB-C.  Once detecting a new input signal, the Transmitter will switch to this new signal automatically.  Manual switching is enabled in the auto switching mode and does not exit it. 5.1.3 Rebooting device The Transmitter can save the last configuration before losing power. If the last switching mode is auto-switching, the Transmitter will automatically enter auto-switching mode once rebooted, then detect all inputs and memorize their connection status for future rebooting using. If the last selected input source is still available, the Transmitter will switch to the input. Otherwise, it will switch to the first available active input source starting at 1-HDMI. 5.1.4 Signal removing Once removing the current display signal, the Transmitter will detect all input signals with priority from 1-HDMI to 4- USB-C. It will transfer the signal firstly detected to be available to output devices.

11 5.1.5 Front Panel button Control  The Receiver features video output port for connecting third-party display device, press the ON or OFF button on Transmitter to turn on or turn off the third-party display device.  The Receiver features audio output ports for connecting speaker or AV amplifier, press the VOL- or VOL+ button on Transmitter to turn down or turn up the volume.  The Receiver features Relay ports for connecting relay device (such as projector screen), press the RELAY1 or RELAY2 button on Transmitter to close the contact closure. 5.2 Third-party display Devices Control Note: If the input source devices, HDMI output display devices support CEC, they can be controlled via the following CEC operation. This Auto operation control includes Transmitter HDMI OUT and Receiver HDMI OUT, and the CEC function can be disabled or abled. 5.2.1 System On When Switcher detects the TMDS or 5V input signal (default: 5V signal), it will perform the following operation steps: 1) Send CEC ON command to third-party display devices; 2) Send RS232 ON + Delay time (default: 3s) +RS232 Display Input selection command to third-party display devices; 3) Perform and control Relay1. 5.2.2 System OFF When Switcher detects all the input source devices were disconnected for XX time long (default: 10 minutes), or receives the standby command, it will perform the following operation steps: 1) Send CEC ON command to third-party display devices; 2) Send RS232 OFF command to third-party display devices, this command can be set to send twice (default: 1 time), delay time default is 1s; 3) Perform and control Relay2. all-guides com

12 6. RS232 Control As RS232 commands can be transmitted to Receiver from the Transmitter, so it is able to control the Transmitter or the third-party device (such as projector) on the Receiver from local RS232 port on the transmitter. The baud rate supports 2400, 4800, 9600(default), 19200, 38400, 57600 or 115200. 6.1 RS232 Connection There are two RS232 control modes.  Control Transmitter  Control Display

13 6.2 RS232 Control Software  Installation/uninstallation  Installation Copy the control software file to the computer connected with the Transmitter.  Uninstallation Delete all the control software files in corresponding file path.  Basic Settings First to connect the Transmitter with all input devices and output devices needed, then to connect it with a PC which is installed with RS232 control software. Double-click the software icon to run this software. Here we take the software CommWatch.exe as example. The icon is showed as below: The interface of the control software is showed as below: Parameter Configuration area Monitoring area, indicates if the command sent works. Command Sending area

Note: Please don’t do anything during the upgrade process to avoid upgrade failure.

40 8. Firmware Upgrade Note: When upgrade Transmitter firmware, it need to be powered via Receiver, so Receiver should be powered well and provide power via HDBT port to Transmitter. Transmitter: 1) Prepare the latest upgrade file (.bin) and rename it as “FW_MERG. bin” on PC. 2) Power off the switcher and connect the FIRMWARE port of switcher to the PC with Type-A USB cable. 3) Power on the switcher and then the PC will automatically detect a U-disk named of “BOOTDISK”. 4) Double-click the U-disk, a file named of “READY.TXT” would be showed. 5) Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk. 6) Reopen the U-disk to check the filename “READY.TXT” whether automatically becomes “SUCCESS.TXT”, if yes, the firmware was updated successfully, otherwise, the firmware updating is fail, the name of upgrade file (.bin) should be confirm again, and then follow the above steps to update again. 7) Remove the Type-A USB cable after firmware upgrade. 8) After firmware upgrade, the switcher should be restored to factory default by sending command. Receiver: 1) Prepare the latest upgrade file (.bin) and rename it as “FW_MERG. bin” on PC. 2) Power off the switcher, and connect the FIRMWARE port of switcher to the PC with Micro USB cable. 3) Power on the switcher, and then the PC will automatically detect a U-disk named of “BOOTDISK”. 4) Double-click the U-disk, a file named of “READY.TXT” would be showed. 5) Directly copy the latest upgrade file (.bin) to the “BOOTDISK” U-disk. 6) Reopen the U-disk to check the filename “READY.TXT” whether automatically becomes “SUCCESS.TXT”, if yes, the firmware was updated successfully, otherwise, the firmware updating is fail, the name of upgrade file (.bin) should be confirm again, and then follow the above steps to update again. 7) Remove the Micro USB cable after firmware upgrade. 8) After firmware upgrade, the switcher should be restored to factory default by sending command.
