100BASE-T1_SPY_12_Port Use Case
The traffic of two BroadR-Reach ECUs is forwarded through the 100BASET1_SPY with
a constant delay of only 1.4µs.
The delay is independent of the frame size of the Ethernet packets.
There is no time jitter on the delay.
The used bandwidth has no influence on the delay.
The traffic of two pairs of BroadR-Reach (so a total of four ports) is forwarded to one
Gigabit Port.
The PC/Datalogger is not able to send data. The RJ45 Ports are output only.
Each RJ45 Port outputs only one 100 Mbit Stream of one of the ECUs.
This setup (Four on One) is implemented three times in one 100BASET1_SPY. So, a
total of 12 BroadR-Reach Ports and 3 Gigabit Ports are used for this.
