| Note: The RBST pin detects the presence of a subsequent node on the ring. In the |

INTERBUS |
|
| |
The drop cable from the fieldbus to the Advantys STB INTERBUS NIM (and the one | |
Networking | from the NIM to the next INTERBUS node) must have connectors that observe this |
Cable and | pin assignment scheme. INTERBUS networking cables are shielded, |
Connectors | electrical cables, compliant with INTERBUS standard |
| be an interruption to any wire in bus cables. This allows for a future specification for |
| use of reserved pins. |
