4.2.4. Troubleshoot
1. Cannot search any devices
Cause A: The IP address type of the device is obtain automatically(DHCP), but currently connected direct via Ethernet cable or connected to a network device(router or switch and so on) which not support HDCP function.
Solution A: Setting up the IP address type of the device to static mode, or connecting the device to a network router which support HDCP function.
Cause B: The device is not power on.
Solution B: Please power on the device.
Cause C: The Ethernet cable is bad contact.
Solution C: Check the Ethernet cable's connection whether is ok.
Cause D: The IP address type of the PC is obtain automatically(DHCP), but currently connected direct via Ethernet cable or connected to a network device(router or switch and so on) which not support HDCP function.
Solution D: Setting up the IP address type of the PC to static mode, or connecting the device to a network router which support HDCP function.
Cause E: Unknown
Solution E: When using direct connection via Ethernet cable, please setting up the IP address type both of the PC and the device to static mode, and the IP address of the both should be in a same network segment. Or when using connection via LAN, connect the PC and the device to a same network router which support HDCP function.
2. The software show a message of 'device response timeout' after connected to the device.
Cause A: The IP address of the PC and the device are not in a same network segment.
Solution A: Setting up the IP address of the both, make sure the IP address are in a same network segment.
3. The software show a message of 'TCP connection failed' after connected to the device.
Cause: The IP address of the PC and the device are not in a same network segment.
Solution: Setting up the IP address of the both, make sure the IP address are in a same network segment.
Note: If the device's IP address type is Auto (DHCP), we can connect to the device via UART firstly, then click the 'Find Via UART' button to read the device's IP address. If the IP address of the device is 255.255.255.255 by this way, it means that the network device (the device connected to) does not support HDCP function.
