CSI 9420
Fast Key Sequence Table 2-3 lists the fast key sequences for common transmitter functions. 
NOTE:
For the 900 MHz CSI 9420, the fast key sequences assume that DD Dev v1, 
DD v9 is being used.
For the 2.4 GHz CSI 9420, the fast key sequences assume that DD Dev v2, 
DD v2 is being used.
This is true for all fast key sequences.

CALIBRATION Sensor Ranges
NOTE
The word “sensor” refers to both an accelerometer and an accelerometer with 
embedded temperature. The word “accelerometer” refers to a sensor that 
measures only acceleration.
Each of the CSI 9420 signal inputs uses accelerometers to make vibration 
measurements. Alternately, an accelerometer with embedded temperature 
may be used. 
Sensor Sensitivity
Each sensor was characterized at the factory to determine the precise 
sensitivity of the sensor. This information is included with the sensor in the 
form of a certificate, and may be cross-referenced with the serial number as 
shown in Figure 2-5 on page 2-10.
