5.6 Troubleshooting
This section provides guidance in troubleshooting SENtral, and is divided into hardware-
related and software-related errors.
5.6.1 Hardware-Related Error Conditions
Possible indications of a hardware-related problem are given below in Table 5-9.
Table 5-9: Hardware-Related Error Indications
Register Name Address Error Indication
EventStatus 0x35
[0] 1 = CPURest. SENtral Configuration
File needs uploading. See Section 5.1.
SentralStatus 0x37
[2] 1 = EEUploadError. Issue with
uploading from the dedicated EEPROM.
See Section 5.1.
MagRate 0x55 0x00 – Value lost
AccelRate 0x56 0x00 – Value lost
GyroRate 0x57 0x00 – Value lost
In the event of such errors, SENtral will enter Standby State, shut down the sensors, and
generate an interrupt to the host. Possible reasons for hardware-related errors include
problems with an external EEPROM upload, power transients detected by power
management, and errors in software detected by Watchdog. Often the error can be
cleared by sending the ResetReq command and reloading the Configuration File.
5.6.2 Software-Related Error Conditions
Possible indications of software-related errors are given below in Table 5-10:
Table 5-10: Software-Related Error Indications

EventStatus 0x35 [1] 1 = Error.
SensorStatus 0x36
Non-zero value indicates sensor-related error. Check
sensors by communicating in Pass-Through State.
See
Table 5-11
SentralStatus 0x37
[3] 1 = Idle. SENtral in Initialized or Unprogrammed
State.
ErrorRegister 0x50 Non-zero value indicated an error. See Table 5-12 .
