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.

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.
