IMU383 Series User's Manual
________________________________________________________________________
When a fault is detected, the system BIT (Section 8.5) will indicate that a fault related to the
sensor fault detection has occurred. This field will not indicate which sensor was removed from
the triad; Fields 0x42 and 0x43 must be read to determine which of the three sensors was
removed from the combination.

User Settings:
Selecting which sensors are included in the output can be accomplished using either the write-
field or set-field command (WF or SF) over UART. Using the SF command will cause the
setting to take effect immediately; the WF command will require a unit-reset before the output is
modified. Several example commands follow:
To get the values for fields 0x42 and 0x43 stored in RAM, use the Get-Field (GF) command:
To set the value for field 0x43 stored in RAM to 0x1 (output sensor #1 only), use the Set-Field
(SF) command:
To change the value for field 0x42 in EEPROM to 0x1 (enable sensor #1 only), use the Write-
Field (WF) command:
