Subject : 
VK1100 IR learning fail
 
Description : 
I use VK6000 IR learning function to learn IR command for the first time, it works fine.
After 1-2 months, I need to add more command but it fails.  How to solve the issue?
 
Solution : 
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.
