Figure 9: Interface Characteristics
An idle line is always marking (in a binary 1 state). Thirty-six (36)
characters in sequence constitute a basic message with default settings.
For more information, refer to “Appendix C: Electrical Signaling ICD”
on page 31.
NOTE: The IMU’s RS422 RX signals are internally terminated to a nominal
impedance of 100
