If we have problems with the receiver, sometimes a log, taken from the COM-port needed. This will require:
- Serial COM-port on your computer, if it is not, then there are adapters with USB to COM.
- Null modem cable that fits both COM port. Doing it yourself is not necessary. It costs a penny in any market where they sell computers (often a null modem cable may already be sold with an USB-to-COM adapter ).
- The terminal program that allows connection to the COM-port. Recommended PuTTY or any built-in OS.
- After connecting the cable, connection to the serial port must be established (port number will depend on the computer or adapter USB-COM) at a speed of 115200. After that, you will see a log on receiver boot. PuTTY allows you to save the log to a file.
