Registration & Automatic binding (Smart Match )
With the FrSky ACCESS protocol, the transmitter/transmitter module can bind receiver without using the "F/S" button.
Follow the step below to finish the Registration & binding procedure:
1. Put the transmitter/transmitter module into [Reg] status.
1.1 For Taranis X9D Plus 2019 as an example, turn on the transmitter, go to the MENU-MODEL SETUP-PAGE 2,choose External
RF-Mode R9M ACCESS, then select [Register].
1.2 For Horus X10 Express as an example, turn on the transmitter, go to the MODEL- EXT MODULE, Turn on the EXTERNAL RF, choose MODE [R9M ACCESS], then select STATE [REGISTER]. REALLY??
2. Connect the battery to the receiver while holding the F/S button on the receiver. The RED LED and GREEN LED on the receiver will
be on, indicating into the [Reg] status. Select [ENTER] on the transmitter, The RED LED and GREEN LED on the receiver will flash,
and the transmitter displays [Registration ok].
3. Turn off the receiver.
4. Move the cursor to select the receiver 1 [Bind].
5. Connect the battery to the receiver, the GREEN LED on the receiver will be on, indicating into the [Bind] status. Select the RX, the
GREEN LED on the receiver will keep lit, the RED LED will flash, and the transmitter displays [Bind successful].
6. The transmitter exit [Bind], the receiver GREEN LED will flash, RED LED will be off, indicating working normally.

R9M Lite/R9M Lite Pro/R9M 2019 with ACCESS firmware per FrSky Web Page

Easily accepted FW update through Smart port (I also did it 3x to be sure)

4. Select Flash xxx(receiver name), wait to end.



Receiver #2

R9 SX

Compatibility: R9M Lite/ R9M Lite Pro / R9M 2019 with ACCESS firmware per FrSky Web Page

Would not accept FW update through Smart port as indicated in readme file:
Firmware Version: v1.3.3

How to update R9SX firmware :
1. Put the firmware under the folder [FIRMWARE] of sd card.
2. Register and bind the receiver with your radio, keep the receiver under working mode. (d’uh NO CAN DO!)
3. Find the firmware in SD folder, select it by press [ENT].
4. Select Flash receiver OTA, re-cycle the receiver power and wait for flash ends.
5. Re-cycle the receiver power and wait for 3 seconds to have connection with your radio again.
Note: Receiver is still supported with flashing firmware by s.port connection to radio.

Radio indicates Receiver NOT responding.

Binding procedure PER Instructions:

NO INCLUSION OF HORUS. NO INCLUSION OF REG IN External Rl in HORUS ETHOS MENU.

1.1 For Taranis X-Lite Pro and R9M Lite Pro as an example, turn on the transmitter, go to the MENU-MODEL SETUP-PAGE 2, choose External RF-Mode R9MLP ACCESS, then select [Reg].
2. Connect the battery to the receiver while holding the F/S button on the receiver. The RED LED and GREEN LED on the receiver will be on, indicating into the [Reg] status. Select [ENTER] on the transmitter, The RED LED and GREEN LED on the receiver will flash, and the transmitter displays [Registration ok]. 3. Turn off the receiver. 4. Move the cursor to select the receiver 1 [Bind]. 5. Connect the battery to the receiver, the GREEN LED on the receiver will be on, indicating into the [Bind] status. Select the RX, and the transmitter displays [Bind successful]. 6. The transmitter exit [Bind], GREEN LED will flash, RED LED will be off, indicating working normally


At both times when powered up holding the F/S button (that button was NOT located on the R9 MM-OTA instructions. Good thing I’m a Sr. PCB LAyout Engineer by trade so I found it.) both green and red led lights were on apparently indication the receivers were waiting for a registration command I could not perform via that ETHOS Menu.

********************
Look, I understand this may be user error. IOW, MY FAULT, possibly for a multitude of reasons. However after 2 weeks of research, countless YouTube Videos, Blogs, even attempting to watch a Video on FrSky’s website won't allow me to figure this out.

The documentation above tells me HORUS has a “REGISTER” selection somewhere under RF SYSTEM>EXTERNAL MODULE. Where is that??


WHAT am I doing wrong?
 
I think for Type (in the picture) you should scroll down to R9M 2019?.... Maybe... They had to have support for both so there may be another selection under R9M.?.
This makes sense because the R9M would not need the register option. It would have been ACCST.
