A: If the R9DS receiver needs to be installed in a car/boat with a full metal casing, it is recommended to use an IPEX to SAM with a sucker antenna. The antenna needs to be drawn out, because if the receiver antenna is enclosed in a metal shell, the metal material will weaken the signal of the receiver, thereby affecting the control distance.

The antenna connector of the R9DS receiver is IPEX. Make sure the sucker antenna has the IPEX connector. Please refer to the picture below:

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

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.

A:

1. When the data read by the user differs from the reference data we provide, please check whether the EPA setting of each channel in the transmitter is the same. If the EPA setting for each channel is different, the read signal range will be different.

2. If the SBUS data cannot be read, please check whether the devices used are working properly and whether there is any problem with the connecting cable.

3. Our products support standard SBUS signals compatible with various flight controllers. Please refer to the chart below for detailed information.

A: You can troubleshoot by the following methods:

1.Check the LED indicator color of R12DS. Red LED represents PWM signal, while blue/purple LED represents SBUS signal. RadioLink flight controller support SBUS and PPM signal. If the receiver indicator is red, please the binding button twice quickly to change the LED from red to blue/purple, SBUS working mode.
