-2000 User Manual
With either setting, the gateway will be identified by the name assigned to it when manufactured
(which is displayed to the right of the Source selection menu). This name provides the host CAN
bus with information about the device that determines its data priority relative to other devices on the
bus (
Table 5 - WSDA-2000 J1939 Values
).

0xFF00 to 0xFFFF
Table 5 - WSDA-2000 J1939 Values
The Destination setting refers to how the sensor data will be received on the CAN J1939 bus and
the desired method of sensor data distribution. Sensor data can be pushed onto the bus either by
sending all of the sensor messages to one CAN device (destination-specific), or by broadcasting
user-selected messages onto the entire CAN bus (broadcast).
l Destination-specific messages can be sent to either a CAN device Address or device
Name. Set Destination to either Name or Address and then type in the device name or
address (as applicable) into the Source field in hexadecimal format. These are the only
setting required for this type of messaging.
l For broadcast messages, the Destination is set to None and the user-designated
messages are constructed either in J1939 Broadcast Message Configuration window or in
a text file that is uploaded from the menu.
To change any of the settings, select from the drop down menus for each one and then select the
Save button to save the selected settings (
Figure 14 - Data Source Setting
).
Broadcast Message Configuration
The J1939 Broadcast Message Configuration section provides a form for the user to define J1939
broadcast messages. The user must specify a unique identifier for each packet called the
Parameter Group Name (PGN). This value is up to the user to select but must be within the range
