2.8.4 Master/Slave Synchronization With Acknowledgement
Figure 2-17 shows the way that the Control Module must be connected for Master/Slave synchronization
with acknowledgement. The individual SW configuration (Master or Slave) is shown in Table 2-16 which
also explains the setting of jumpers 12, 13 and 14 (JP12, JP13 and JP14).
