8. MDI_AUX_MASK=x
x — 24-bit mask, hexadecimal number 000000…FFFFFF
Factory setting: 000000
This parameter controls mapping of the signal of auxiliary sensor of the Volvo Penta MDI (AUX, see VI.1)
to the engine’s status in the NMEA 2000 network. For example, if an auxiliary sensor is installed
and signals that there is water in the fuel, set the value of the mask in 000100 (hexadecimal number,
bit 9 is set) in accordance with the table in Appendix B. See also MDI_PROP_MESSAGE.
9. MDI_SYS_FAULT_MASK=x
x — 24-bit mask, hexadecimal number 000000…FFFFFF
Factory setting: 000000
Displays the «System fault» status of the Volvo Penta MDI block (see VI.1) on the status of the engine
on the NMEA 2000 network. See also the description of MDI_AUX_MASK and MDI_PROP_MESSAGE.
10. ALERT_x=[y,w,z|OFF]
x — digit from 0 to 9, internal index of the Device
y — 24-bit mask, hexadecimal number 000000…FFFFFF
w — decimal number of SPN, see the manual of your specific engine
z — decimal number FMI, from 0 to 31, see the manual of your engine
When a diagnostic message (PGN 65226) with specified SPN and FMI codes is received from the engine,
set the bits of the engine status in NMEA 2000 to according to the mask. For example:
ALERT_0=000020,158,1
Set the sixth bit (hexadecimal 000020) in the engine status (see Appendix B), indicating «Low System
Voltage», when a diagnostic message received with the SPN and FMI equal to 158 and 1, respectively.
