Q:Can the AT9S upgrade to AT9S  Pro by upgrade firmware ?

A: It can’t. AT9S and AT9S PRO are difference both communication and hardware, so AT9S cannot upgrade to AT9S PRO by upgrading firmware.

Q:How to distinguish AT9S and AT9S PRO?

A:You can check the PCBA version from the battery box of AT9S as the picture below. If the hardware version of your AT9S is 2.0, It cannot compatible with the TBS crossfire. If it is V3.0, it is AT9S PRO and compatible with TBS crossfire.

 

 

 

Q: Can the AT9S upgrade with the firmware of AT9S Pro?

A: Yes. The AT9S can upgrade with the firmware V2.0.6 of AT9S Pro or above.

Q: How to setup parameters to use transmitter AT9S Pro and receiver R9DS to control a RC car with dual ESCs?

A: connections and settings as below:

Transmitter: Radiolink AT9S Pro

Receiver: Radioink R9DS (should be with PWM signal output, that means have to make sure the Red LED of R9DS always on)

Tank: dual motors RC tank, each motor controlled by an ESC separately

 

Connection:

The head of tank is forward.

The ESC on left connect to the CH1 of R9DS.

The ESC on right connect to the CH2 of R9DS.

 

Transmitter Setting:

Into BASIC MENU---select MODEL TYPE---set the TYPE is ACROBASIC

 

 

 

 

 

Into PARAMETER menu---set STK-MODE:2

 

 

 

 

Into ADVANCE MENU

select PROG.MIX1 menu

set both left and right RATE to +100%

set MIX from INH to ON

set MASTER:CH1 and SLAVE:CH2

set control switch is SwB and the POSI of switch is UP, the parameters as the picture below

 

 

 

Back to PROG.MIX menu

select PROG.MIX2

set both up and down RATE to -100%

set MIX from INH to ON

set MASTER:CH2 and SLAVE:CH1

set control switch is SwB and the POSI of switch is UP, the parameters as the picture below

 

 

 

Then go to the SERVO menu to check if the phase is right or not.

When push the joystick of CH2 to up or down, then the servo bar of CH1 and CH2 will move to up and down at the same time, the servo bar of CH1 and CH2 to the same direction.

When push the joystick of CH1 to left or right, then the servo bar of CH1 and CH2 will move to left or right at the same time, but to the opposite directions.

 

 

 

 

 

If the servo bar of CH1 or CH2 is not move as the introduction above, it means the phase is reverse, you have to set as below:

Into BASIC MENU

Select REVERSE

Set 1:AILE is NOR and 2:ELEV is REV

 

 

Q: Will the parameters of different model types set before be cleared or modified once the firmware flashed/upgraded?

A: No. The firmware upgrade won't change any personalized parameters already set.

 

 

Q: What are the compatible receivers to AT9S Pro?

A: The standard packed receiver with AT9S Pro is R9DS, which is a 10-channel receiver that supports SBUS and PWM signals synchronously with 2.4G DSSS&FHSS spread spectrum technology.

Besides R9DS, there are also other compatible receivers with different channel quantities available.

R6DS- 6 channels(PWM signal output), 10 channels (SBUS/PPM signal output)

R12DS- 12 channels (SBUS&PWM signals output), 11 channels(PWM signal output)

Mini receivers: R6DSM- 10 channels (SBUS/PPM signal output)

R12DSM- 12 channels (SBUS/PPM signal output)

Note

The default channel quantity of AT9S Pro is 10 to work with the standard packed receiver R9DS. When working with the 12-channel receivers (R12DSM,R12DS), the channel quantity of AT9S Pro should be changed as CH:12.

Long press the Mode key to enter the BASIC MENU -> Rotate the scroll Dial to highlight the SYSTEM option and press Push to enter -> Select the CH-SELECT and change the Number as required.

* All RadioLink transmitters are not open sourced and can only bind to receivers developed by RadioLink.
