4.14.2. Combining EtherCAT and USB chain
When using USB SIRIUS devices and EtherCAT devices we need sync junction to synchronize the USB
and ECAT data. The sync junction will provide a clock source for synchronization. External timing sources
like GPS or IRIG can be connected and used. When we calculate the bandwidth of a system we need to
acknowledge that we have two data lines in our system - USB and EtherCAT.
Synchronizing data from USB and ECAT data lines with Sync junction
List of required cables:
EtherCAT to EtherCAT: L1T8m-L1T8f,
ECAT - PC connection: L1T8f-RJ45
