Constructing Networks with Repeater Units Section 3-4
Partial Conversion to Optical Fiber
Combining T-Branch Wiring (2-stage Repeater) and Partial Optical Fiber
Note When constructing a network using Repeater Units, each segment must sat-
isfy all of the following requirements:
• The total number of Controller Link Units, Support Boards, and Repeater
Units within a single segment must not exceed 32.
• The total cable length of a single segment must not exceed the specified
value. (500 m at 2 Mbps; 800 m at 1 Mbps; and 1 km at 500 Kbps.)
• The maximum number of repeater stages that can be inserted into the
path connecting any two nodes is two.
• The node at each end of a segment (including Repeater Units) must have
terminating resistance turned ON.
• The baud rates within each segment must be set to the same value.
