 - To verify that the TX is in fixed mode: power cycle the TX, the module LED should be solid ON (no blink).
 - Note: Autobind/fixed ID mode is linked to the RX_Num number. Which means that you can have multiple dial numbers set to the same protocol DEVO with different RX_Num and have different bind modes at the same time. It enables PPM users to get model match under DEVO.
