7.3 ETH #1 / TSL and ETH #2 / TSL
The network ports at the front side, ETH #1 / TSL and ETH #2 / TSL, are for the communication
between logger and client as well as for logging data.
Further they can be used to combine blue PiraT Mini and blue PiraT2 data logger to a combined
TSL (Telemotive System Link) and synchronize these loggers.
Warning:
Don’t connect ETH #1 and ETH #2 directly to each other.
