ESC Soft Off – We have noticed that some ESC / Receiver combinations react poorly when the receiver power is switched off while the flight batteries are still connected, resulting in a sudden (but short) kick of the motor. This situation presents some danger to the user, and mechanical stress to the motor and drive. This device resolves this issue, allowing you to turn off the receiver power with the flight batteries still connected. No programming changes to transmitter or ESC are required.
Note it is extremely important you test this feature in a controlled environment, and regardless always treat the propeller as live with flight batteries connected.
Quick start hint: If you are only interested in this feature (and not telemetry), simply plug the THROTTLE PWM channel on your receiver into this device’s ‘SBus/2 Input’ and plug the ESC into the ‘PWM Out’ on this device. Most people won’t run their ESC through this device – it is only there if you have an ESC / receiver combination that results in a motor ‘kick’ when you turn off the receiver power with the flight batteries still connected.
Telemetry – Receiver Frame Losses, Fail safes, Signal Quality and Frame Loss Rate When using the device via SBus2 (and 18 channel FASSTest or T-FHSS), you can receive frame losses, fail safes, receiver signal quality and frame loss rate information on your transmitter – and set warning alarms for these parameters. Further, your ESC can be plugged into the PPM output of the device to use its soft stop feature (by default, the PWM output is set to channel 3 – throttle). When used on SBus2 FASSTest 12 channel mode, or any SBus mode (with no telemetry), your ESC can be plugged into the PWM output of the device, and smooth stop used. Additionally, the device shows LED indication for failsafe condition, and LED indication for more than 999 frame losses during a flight.
