BIT Fault
Fault code for active fault. If more than one fault is active, as
indicated by the BIT Count, the active faults codes will cycle on
each successive ping. Fault codes include:

BIT count
This field contains the current number of active faults detected by
the Sentinel V Built-in Test function. A zero code indicates no
active faults.
29-32
15,16
EC / Speed of
Sound
Contains either manual or calculated speed of sound information
(EC-command).
Scaling: LSD = 1 meter per second; Range = 1400 to 1600 m/s
33-36
17,18
ED / Depth of
Transducer
Contains the depth of the transducer below the water surface
(ED-command). This value may be a manual setting or a reading
from a depth sensor.
Scaling: LSD = 1 decimeter; Range = 1 to 9999 decimeters
37-40
19,20
EH / Heading
Contains the heading angle (EH-command). This value may be a
manual setting or a reading from a heading sensor.
Scaling: LSD = 0.01 degree; Range = 000.00 to 359.99 degrees
41-44
21,22
EP / Pitch
(Tilt 1)
Contains the pitch angle (EP-command). This value may be a
manual setting or a reading from a tilt sensor. Positive values
mean that Beam #3 is spatially higher than Beam #4.
Scaling: LSD = 0.01 degree; Range = -20.00 to +20.00 degrees
45-48
23,24
ER / Roll
(Tilt 2)
Contains the roll angle (ER-command). This value may be a
manual setting or a reading from a tilt sensor. For up-facing,
positive values mean that Beam #2 is spatially higher than Beam
#1. For down-facing, positive values mean that Beam #1 is
spatially higher than Beam #2.
Scaling: LSD = 0.01 degree; Range = -20.00 to +20.00 degrees
