CAN bus connection
When connecting equipment to the CAN bus interface like fiber-optic CAN bus
converters, ensure that both devices support the same transfer rate.
Use the cable R&S OSP-Z106 to connect the R&S OSP device to the fiber-optic CAN
bus converter.
Use the cables R&S OSP-Z101 or R&S OSP-Z102 to connect two R&S OSP devices.
These cables do not connect the 12 V DC line of the CAN bus.
9.1.2.2 LAN REMOTE
8-pin connector RJ-45 used to connect the R&S OSP to a Local Area Network (LAN).
Refer to Remote Operation in a LAN and LAN Interface. The pin assignment of the
RJ-45 connector supports category 5 and 6 UTP/STP (Unshielded/Shielded Twisted
Pair) cables.
This connector is not available on the R&S OSP150.
It is recommended to use double-shielded LAN cables of category 6 (SSTP).
