General Information and Tips

General

We are NOT experts at the Graupner Hott system. We did implement there single wire SRXL Protocol SUMD. Aura can get 12+ channels of data on a single wire using SUMD.

The specific equipment we have tested and flown includes an MX-16 transmitter, and GR12L and GR16 Recievers.

Tips

• Update your transmitter to the latest firmware.
• Update your receiver to the latest firmware.
• With your receiver bound, go into your transmitter menu structure following its instructions (sometimes in Telemetry menu) and Enable SUMD (This must be done, it is not done/on automatically/by default). Not which pin the SumD is assigned to on your Rx Bus.
• Taking extra care with the polarity, connect the SumD Rx port to servo Port B of the Aura using one male-to-male cable.
• Most of our testing has been with SUMD of 8, and of 12.
  • It seems the GR16 defaults to SumD of 8 (using our MX-16)
  • It seems the GR12L defaults to SumD of 12 (using our MX-16)
• The GR16 is easiest to use on PNP aircraft like the Extra and Aura, or with Quick Set on the Open Stock Aura. Aura can Auto-Detect SumD of 8 (unless Auto-Detect disabled, refer to your products user guide.)
• Some transmitters or devices may allow you to re-program the SumD channel count?
• As needed, use the Aura Config tool to go in and select the correct radio settings for Aura

Graupner -> Graupner SumD -> On Port B -> SumD of 8, or 12 etc.

• Once Connected, you will have on Aura:
  • Solid Orange LED - Power and Calibrated Sensor (blinking is movement during sensor calibration, using last good)
  • Solid Green LED - Valid Radio Data Source (blinking is error/wrong channel count)
• Turn on the Aura Live Data/Input Monitor to see your input commands and validate functions.
  • Assign a 3-position switch to the Tx CH5. Is CH5/Flight Mode change in Aura
  • Assign a switch (or other) as needed to CH6 and CH7 to use for flaps, etc. as desired.
  • Assign a knob (or other) as needed to CH8. This can be used as Aura master gain if desired.
• Tx Flight Control directions into Aura Input Monitor should be correct with default/normal Tx servo reversing.
• Set travel per normal Aura directions (125% Aileron, Elevator, Rudder, 100% others)
