This sentence provides the response data for thruster devices.
$xxTRD, x, x.x, A, x.x, A, x.x, *hh<cr><lf>
0 1 2 3 4 5 6 7
0) Header
1) Number of thrusters
Odd = Bow thruster
Even = Stern thruster
2) RPM demand
3) Data status
R = relative (%): 0-100% from zero to maximum rpm
T = true (deg) V = data invalid
4) Pitch response value
"-" port
5) Data status
R = relative (%)
T = True (deg)
V = Data invalid
6) Azimuth demand
Direction of thrust in degrees (0 deg - 360 deg)
for thrusters capable of rotating direction of thrust
7) Checksum
