cOM VIEwER:
Displays last messages received on J1939
(CAN), NMEA 0183 (GPS-derived speed over ground data) and
J1587 ports. System settings stored in memory can be seen in
the EEPROM Viewer.
Note. This is a diagnostic feature that displays the contents of
the EEPROM with the current values. This may be helpful for
OEMs/users diagnosing faults.
DATALInk sETTIngs:
This sub-menu allows the user to configure the common datalink
settings (Speed Source & Trip Source) as well as the individual
J1939/J1587 settings (such as source addresses).
J1939 sETTIngs:
This screen allows adjustments specific
to the J1939 Datalink.
sOURcE ADDREss 1 & 2:
These settings allow the
display to filter which sources it will listen to for data. Every
device on a J1939 network will have a unique address (in the
range 0-254) which the Engine Monitor can choose to listen
to or not. The Engine Monitor can listen to 2 sources of data
simultaneously (usually Engine 1 - address 0 and Transmission
1 - address 3). The filter can also be removed so that the Engine
Monitor will decode all incoming data regardless of its source.
This is accomplished by setting “Source Address 1” to 255.
