Description "G" requests a single data packet. DMU will
respond with a data packet. The format of the
data packet will change with the measurement
mode (Raw, Scaled, or Angle). Sending the
DMU a "G" while it is in Continuous Mode will
place the DMU in Polled Mode.
Command Set Erection Rate
Character(s) Sent T<x>
Response none
Description The T command sets the vertical gyro erection
rate. The argument of the command <x> is a
single binary byte that represents the value you
want to set as the erection rate. The units are in
degrees per minute. For example, if you wanted
to set the erection rate to 50 deg/min, you would
send the command T<50>, which in hex would
be 54 32.
Command Calibrate Rate Sensor Bias
Character(s) Sent z<x>
Response Z
Description Measure the bias on each rate sensor and set as
the new zero. The DMU should be still
(motionless) during the zeroing process. The
argument of the command <x> is a single binary
byte that the DMU normally ignores and hence
any single byte character can be sent. The
zeroing command turns on the high-pass filter
rate estimation that takes approximately 3
minutes.
If <x> is set to 0, then the previously stored gyro
biases are erased.
Command Query DMU Version
Character(s) Sent v
Response ASCII string
