Extension IN (X14) & Extension OUT (X15)
The EPOS4 50/5 features two NET connectors for extension communication interfaces, such as EtherCAT.
One serves for NET input, the other for NET output. Both sockets are identical in respect to their external
wiring.
Wrong plugging may cause hardware damage
Even though both NET sockets are prepared for identical external wiring, make sure to always connect
them as follows.
• Use only standard Cat5 cables with RJ45 plug, such as maxon’s «Ethernet Cable» (422827).
• Use IN (X14) as «Input».
• Use OUT (X15) as «Output».
For detailed information see separate document
«EPOS4 Communication Guide».
