Figure 2-13. USER/DEF Switch in Factory-Default Mode
In factory-default mode, the FP-1300 transmits CAN messages for input
I/O data periodically every 500 ms. You can configure the periodic rate as
well as other CAN message transmissions using the FP-1300 Configuration
Utility. Refer to
FP-1300 Configuration Help for more information about
configuring CAN messages on the FP-1300.
Configuring the Arbitration ID Type (STD/XTD)
You can configure the FP-1300 to send and receive standard arbitration ID
messages or extended arbitration ID messages. For more information on
standard and extended messages, refer to the
NI-CAN Hardware and
Software Manual . If you want the FP-1300 to send 11-bit standard ID
messages, push the STD/XTD switch to the STD position.

Configuring the Base Arbitration ID
Each FP-1300 on a CAN network must have a unique base arbitration ID.
All CAN messages sent or received by the FP-1300 have arbitration IDs
that are offset from the base arbitration ID of the FP-1300. The FP-1300
configures the CAN message arbitration IDs, but you can change this
configuration using the FP-1300 Configuration Utility. For more
information about the CAN message arbitration IDs default configuration,
refer to the
FP-1300 CAN Message Arbitration IDs section.
