Cable lengths and number of nodes
The maximum cable length allowable in one segment is dependent on the transmission speed. The total cable length includes drop cables if any. A drop cable is the connection from the main bus cable to each node. If a T- connection is used, permissible cable length and maximum number of nodes/drives are 1, 2, 3 and 4 bus segments.
Drop cable connection (i.e.,
Note that a repeater is a node in both of the two segments it connects. The number of adjustable frequency drives is based on a single master system. If there are two or more masters (e.g., PC tools, routers), the number of adjustable frequency drives must be reduced correspondingly.
