Hello ACEINNA support,
I am using the MTLT335D IMU by ACEINNA. I have it positioned on my desktop. It is powered externally. I am successfully communicating over RS232 (NAV-VIEW) and CAN.
When I request Acceleration Sensor (PGN 61485, 0xF02D), the 7 byte is 0x80. This is "Lateral Acceleration FOM=Error".

When I request Angular Rate (PGN 61482, 0xF02A), the 7 byte is 0x40. This is "Yaw Rate FOM (Extended Range)=Degraded".

Per Table 79 and Table 72:
There does not appear to be anything set in the Master BIT (below)
Get Master BIT:

The Software BIT is interesting. Per MTLT335D Series User's Manual, Table 19, bit 28 "Transmit queue overflow Error" is present.

There does not appear to be anything set in the Hardware BIT:

Also per Table 79 and Table 72, cycling power on the device does not clear Acceleration Sensor, Angular Rate byte 7 status. Each time I apply power it is the same result (0x80 and 0x40).
I have the following questions:
- What is causing Acceleration Sensor byte 7 and Angular Rate byte 7 to get set?
- What causes a SW BIT "Transmit queue overflow Error" to happen?
- I have "7430-3003-06 User Manual MTLT335D.pdf" dated "Aug 9, 2023 -06 06.05". Is this the latest version?
- Per NAV-VIEW 3.5.12, I have firmware
5020-3327-01 06.03. Is this the latest version? - Per NAV-VIEW 3.5.12, "Sensor Status Enable Fields, Sensor Over Range" appears to be set. What causes this to happen?
NAV-VIEW Capture:
Read Unit Configuration shows "Sensor Over Range" set.
Your help in this matter is greatly appreciated.
Kind regards,
Jason Majchrzak
