TX
Flashes when messages are being
transmitted
Err Flashes when errors occur on the bus
If the RX or TX light is flashing when there is CAN traffic on the bus, then you can assume that
the Trigger Module connection to the bus is correct.
If the Err light is flashing, or if there are no lights flashing, then there is something wrong with
the connection of the Trigger Module to the bus. Re-examine your wiring connection, make
sure that you are using the correct cable and/or correct termination, and make sure that the bit
rate is set correctly in the CAN Trigger dialog.
If you see either or both of these error messages (shown in the picture
to the right) in the CAN Trigger dialog, then you need to re-examine the
connections to the Trigger Module and make sure that they are correct.
This message will be replaced by Trigger Module attributes and trigger
coupler information when the Trigger Module is properly connected.
There are also optional cable sets that may be purchased for both high-speed and low-speed
CAN. These cables have 9-pin DSUB to 9-pin DSUB connectors, and are useful if your embedded
controller has a 9-pin connection for CAN. It is also simple to build these cables. The cables and
cable sets are described below (schematic detail is provided in Appendix A)
