Branch Line Support for Cable Types and Baud Rates

■ Baud Rate of 93.75 kbps
Note This is the maximum number of Slave Units and Repeater Units combined
that can be connected to a branch line by using multidrop connections and/or
T-branching. T-branching creates a sub-branch.
Support for branch lines from the trunk line or sub-trunk lines and support for
sub-branch lines from branch lines is listed in the following tables.
■ Baud Rate of 4 Mbps (No Branch Lines)
Cable
Round Cable I
Round Cable II, Flat Cable I, or Flat
Cable II
Note A baud rate of 4 Mbit/s is not supported for branch lines and thus
cannot be used for Slave Units with Cables (i.e., Bit Slave Units).
The network must consist of only Word Slave Units and DCN4-
MD4 Multidrop Connectors must be used for Flat Cable I and Flat
Cable II cables.
