| Because customer uses the first IR port of VK1100 is the default IR learning port, please avoid to change port 1 to use as RS232 port. The issue happens because customer set IR port 1 as RS232 port and port 2 as IR port. After upload the project the IR port 1 has been changed to receive RS232 command, so it couldn't be used for IR learning. The solution for this project is to set the IR port to port 1 and RS232 port to port 2 to use. |
