JR Protocol Guide

JR DMSS Transmitters and Receivers work great with Aura. Any old JR DSM2/DSMX protocol transmitters should follow the Spektrum Use Guide

XBus

The JR way to connect a JR receiver to an Aura is with their XBus Protocol. Depending on your Transmitter and Receiver, you can configure the XBus Port to output in JR Mode A or JR Mode B.

• JR Mode A (Preferred)
  • High resolution, single cable digital data connection similar to Futaba SBUS
  • Supported in Aura Firmware to v1.14+ which was released in August of 2020
  • The Receiver XBus Port is connected to the Aura 5 or Aura 8's B Port, either the A Port or B Port can be used for Aura 8 Pro or Aura 12 Pro.
  • When using JR Mode A, the other Servo Ports on the Receiver operate as normal servo ports

• JR Mode B
  • High resolution, single cable digital data connection similar to Futaba SBUS
  • Older, legacy protocol from JR similar to Spektrum SRXL
  • The Receiver XBus Port is connected to the Aura 5 or Aura 8's B Port, either the A Port or B Port can be used for Aura 8 Pro or Aura 12 Pro.
  • When using JR Mode B, the Servo Ports on the Receiver are disabled which is a big drawback especially for larger, more complex airplanes

Traditional PWM

The old school way to connect a Recever to Aura but is more complicated, restrictive and not recommended for new setups.

• Supports virtually every receiver but lower resolution and more complicated
  • Individually connect the Receiver Aileron, Elevator, Rudder, and Gear servo ports on your Receiver directly to a Servo Port setup as an Input on the Aura.
  • Since multiple Aura Servo Ports are used in Inputs from the Receiver, there are less Gyro Stabilized Servo available to be used as Outputs
• Some features such as QuickSetup and QuickTrim are NOT supported with PWM connections.

JR Receiver Guide

The BX series of receivers is most commonly used with Aura. The RG712BX and RG812BX have been tested extensively and are known to work well with Aura.

BX

• Commonly used with Aura
• Feature a single dedicated XBus Port

BPX

• Often include different built-in power connector such as Deans, XT30, XT60, etc
• Does not hav a single dedicated XBus Port
• The Servo Ports can be setup to be all Traditional PWM Outputs or all XBUS Outputs.
  • The servo ports are switched between PWM and XBus using the SENS/MODE port on the BPX receiver.

JR Transmitter Setup Guide

Traditional JR Transmitters include T14/T44

JR Elite and JR Matrix Transmitters

JR DMSS Installation Notes and Equipment Selection

NOTE: This applies to JR radios using the DMSS protocol. Radios using the DSM2/DSMX protocol should follow the Spektrum instructions. There are several ways to connect the Aura to your JR DMSS Receiver:

• JR Mode A serial protocol (preferred)
• JR Mode B serial protocol (legacy)
• Traditional PWM Servo Connection

NOTE: Any recommendations are based on years of knowledge and product use and are informational only.

• We do not 'specify' radio installations. Consult your radio manufacturer for radio information.
• We test and support the use of genuine JR brand equipment only.

JR Mode A (Preferred)

JR Mode A is modern digital serial data on one wire (similar to Futaba S.Bus). It gives the Aura precise knowledge of all of the available JR channels.

• Most Preferred and capable JR connection
• Please update Aura Firmware to v1.14 or newer!
• Current information indicates that the best receivers are the 'BX' series such as the RG812BX. The 'BPX' series apparently cannot do Serial Data and conventional PWM servo ports at the same time. Older receivers like the RG712BX with and XBus port are tested and working.
• Aura will follow the Failsafe outputs of the JR Receiver.
• Recommended for all aircraft types
• Receiver Ports can be used along with Aura Ports.
• JR Mode A is input into standard Aura 5 or 8's B Port (servo bus). The A Port is preferred for Aura Professionals.
• Generally we recommend full range receivers for aircraft up to 49cc, and full range receivers with 3 or more receivers (antenna) for 50cc and larger aircraft

JR Mode B (Legacy)

• JR Mode B is a more simple serial protocol
• JR Mode B is input into standard Aura 5 or 8's B Port (servo bus). The A Port is preferred for Aura Professionals.
• Aura has knowledge of all available JR channels
• The Receivers Servo Ports are DISABLED when Mode B is enabled. This is a major disadvantage.
• If using Mode B, set Aileron, Elevator, and Rudder travel to 88% in Transmitter. Set other channels to 88% or less as needed. (Data restraint in Mode B protocol)
• While it is the users discretion, we no longer recommend Mode B use on ignition engines. With the availability (FW v1.14) JR Mode A in Aura, we feel it is more conservative and appropriate to use Mode A as it offers the benefits of additional buffer between the ignition and the Aura, and working receiver ports for the throttle, choke, and ignition which driven directly by the receiver's failsafe.

Traditional PWM Servo Connection

PWM (Servo Leads) connect the each channel on your Receiver directly to each Servo Port on the Aura.

• Recommended for all aircraft types.
• Supports virtually every receiver
• Limits port availability. Typically Aura will be configured with 4 inputs and 4 outputs with PWM. (8 outputs with Aura 12 Professional)
• Some features such as QuickSetup and QuickTrim are NOT supported with PWM connections.
• All (typically 4) PWM (servo jumper) connections MUST be present to get control of the model which is indicated by a solid green Aura LED (valid radio signal)

General Transmitter Settings for JR MODE A

Start with a Blank Model and reference the Chart!

Common Transmitter Settings for Aura5, Aura 8 and Aura Professionals starting with a freshly reset transmitter and maintaining normal wing and tail types. NOTES:
1. JR Mode A is preferred as of Aura FW v1.14. For JR Mode B, see the Aura Wiki
2. If you are using a Futaba transmitter, please note that some Futaba transmitters have the throttle set to reversed by default. Leave reversing set to defaults to start, and reverse as needed.
3. Aileron, Elevator, and Rudder should NOT be Reversed, other channels may be reversed at users preference
4. If Flight Modes are set to a channel other than CH5/Gear, set a 3-position switch to that channel and set CH5/Gear as needed.
