Real world example
The most common combination is that you already own a Crossfire transmitter to which all your receivers
are bound and now you have a second transmitter like the Tango 2. Here is how you get them both
running with Multi Bind, assuming that you already got you user id on both transmitters:
1. Make sure both radios got the same firmware version
2. Power up your “old” transmitter and make sure Multi Bind is turned off for now
3. Power up the receiver - if you updated this transmitter, run the OTA update by the autobind
feature
4. Turn Multi Bind
on
- the link will break up for 1or 2 seconds and will be regained then
5. Shut down the receiver
6. Turn Multi Bind
off
in your “old” transmitter
7. Power up the next receiver
8. Repeat step 4 till all your receivers are switched to multi bind
9. When the last receiver is set to Multi Bind, let it enabled in your “old” transmitter
10. Power you new Transmitter
11. Turn Multi Bind
on
12. Power up a receiver - your new transmitter will bind to your receiver as the old transmitter did
If the switching fails, you can turn on multi bind on your transmitter and then bind the receiver with the
Bind
button (classic binding).
Keep in mind that when you use the Model Id (FreedomTx)/ Receiver number (OpenTx) feature that they
need to match in both radios!
Nice to know
When you bind a new receiver, it will remember the serial number of the transmitter it was bound. As an
example your serials number looks like this:
123456
When the Model ID/ receiver number feature was introduced, these numbers got attached to the serial
number:
123456
00
. (with Model id = 05:
123456-05
)
When you enable Multi Bind, the serial number of the transmitter will not be used. Instead the receiver
gets your user id as “transmitter serial number” which looks like this:
12345
(+ model id)
As all of your transmitters share the same User Id they are like the same transmitter for your receiver.
