The device can be connected to Ethernet-based communication
systems via the RJ-45 connector (100Base-TX) or the fiber optic
LC connector (1000Base-SX), depending on the product variant.
The device supports the following high accuracy time synchro-
nization method with a timestamping resolution of 4 μs required
especially in process bus applications.
