Specification for Spektrum X-Bus Telemetry Sensors
Page 8 Rev E
The “mAh” configuration screen provides the same functions available to other devices, that is,
whether the status is actively monitored on the display. Alarms are available for the following
conditions:
Battery 1 capacity consumed > user-defined value
Current 1 too high
Temperature 1 too high
The units and ranges for each of the fields in the telemetry message are found in the appendix in the
definition for the MAH structure. The transmitter does not provide any filtering of data for any fields.
12 DIGITAL INPUT AND AIR PRESSURE SENSOR
The AirWare-based transmitters may include support for a generic digital input and air pressure
metering device. Spektrum does not sell a device which conforms to this telemetry standard, but is
instead providing a common interface which may be supported by third-party manufacturers.
The “Air” configuration screen provides the same functions available to other devices, that is, whether
the status is actively monitored on the display. Alarms may be available for the following conditions:
Digital Bit set (bits 0-16)
Digital Bit clear (bits 0-16)
Pressure too low
Pressure too high
The units and ranges for each of the fields in the telemetry message are found in the appendix in the
definition for the DIGITAL_AIR structure. The transmitter does not provide any filtering of data for
any fields.
13 THRUST/STRAIN GAUGE
The AirWare-based transmitters may include support for a generic thrust or strain metering device.
Spektrum does not sell a device which conforms to this telemetry standard, but is instead providing a
common interface which may be supported by third-party manufacturers.
The “Strain” configuration screen provides the same functions available to other devices, that is,
whether the status is actively monitored on the display. Alarms may be available for the following
conditions:
Single Strain too high (any input above threshold)
Sum Strain too high (sum of active strains above threshold)
Strain Imbalance (delta of min/max strains on active inputs is above threshold)
The units and ranges for each of the fields in the telemetry message are found in the appendix in the
definition for the STRAIN structure. The transmitter does not provide any filtering of data for any
fields.
