RS 422 / 485 Field Bus
If possible, connections between ITCS and displays or vehicle position detection units will be established via data cable.
LUMINO uses a balanced line-based field bus congruent with RS-422/485-specifications that can be installed maintenance-friendly (without terminating resistors) as an unstructured bus or tree. Since the cable length of such a field bus segment can be up to one kilometer and the maximum user number can be up to 32, it is often useful to connect several stations or tracks to a common system.
Optionally a display can also be connected to an existing standard Ethernet. ITCS-manufacturer-specific features (e. g. current loop) of the interface hardware or the protocol software can be incorporated on demand.
