3.5.5 Using the Group Trigger
The SDM-Group Trigger controls SDM devices that support the Group Trigger
protocol, including the SDM-CAN. All Group Trigger devices are triggered to
make simultaneous measurements, the data is then retrieved by using the
appropriate instruction.
For the SDM-CAN, this instruction is can be used in a vehicle where more than
one CANbus network is present. An example of using the group trigger is shown
below.
