 ###Using a serial output
-The multiprotocol TX module can be used on a Turnigy 9X, 9XR, 9XR Pro, Taranis, ... running [er9x or ersky9X](https://github.com/MikeBland/mbtx/tree/next). (A version for OpenTX is being looked at)

-Using this solution does not need any modification of the TX since it uses the TX module slot PPM pin for serial transfer.

-Channels order is AETR by default but can be changed in the source code.
 
 This enables full integration using the radio GUI to setup models with all the available protocols options.

 ###Telemetry
-Telemetry is available for er9x and ersky9x TX.
+Telemetry is available for er9x and ersky9x TXs.
 There are only 2 protocols so far supporting telemetry: Hubsan and Frsky.
 
 To enable telemetry on Turnigy 9X or 9XR you need to modify your TX following one of the Frsky mod like this [one](http://blog.oscarliang.net/turnigy-9x-advance-mod/).
 
+Enabling telemetry on 9XR PRO and may be other TXs does not require any hardware modifications. The additional required serial pin is already available on the TX back module pins.
+
+Once the TX is telemetry enabled, it just needs to be configured on the model as usual.
 
 ##Protocols
 
 ###TX ID
-Each protocol is using a 32bits ID generated randomly at first power up. There are little chances to get a duplicated ID.
+The multiprotocol TX module is using a 32bits ID generated randomly at first power up. This global ID is used by all protocols.
+There are little chances to get a duplicated ID.
 
 It's possible to generate a new ID using bind button on the Hubsan protocol during power up.
 
 ###Bind
-To bind a model press the bind button, apply power and then release.
+To bind a model in:
+1. PPM Mode:
+- press the bind button, apply power and then release.
+2. Serial Mode:
+- use the GUI, access the model protocol page and long press on Bind.
+- press the bind button, apply power and then release will request a bind of the loaded model protocol. Note that the bind button is only effective at power up and not when the protocol is changed on the fly.
