The STB NIB 2212 NIM Module

31004624 8/2009
NOTE:  The RBST pin detects the presence of a subsequent node on the ring. In 
the absence of this detection (or if the node has no out connector at all), the network 
ring is closed.
INTERBUS Networking Cable and Connectors
The drop cable from the fieldbus to the Advantys STB INTERBUS NIM (and the one 
from the NIM to the next INTERBUS node) must have connectors that observe this 
pin assignment scheme. INTERBUS networking cables are shielded, twisted-pair 
electrical cables, compliant with INTERBUS standard DR-303-1. There should not 
be an interruption to any wire in bus cables. This allows for a future specification for 
use of reserved pins.
