To use the secondary reciver, the following steps are required
Install the Module "Secondary Receiver" from "Setup" Section on the radio (Touch oder EVO)
Update of a EVO/NEO with the Firmware "Secondary Receiver with PC or radio
Bind VBar EVO like any other receiver. It shows up as "Second RX"
Create a default setup. This is always necessry to get rid of existing older settings, it's like a factory reset.
Programming is done via macrocells. Just the number of inputs is limited, since information from the Master Flight Control are not available to the secondary RX.
Flight relevant setup must always be done on the (primary) Master VBar.
For safety reasons, you may only set up fuctions on a secondary receiver which are not mission (flight) critical!
Attention: this RX2 configuration can not be updated/downgraded to a different firmware version, form the transmitter. Use a computer with VBar Control Manager (same as if you were using Extender, Sensor Hub firmware.
