CompoNet Network Specifications Section 1-2
■ Baud Rate of 3 Mbps
Note The maximum number of nodes per branch is the maximum number of Slave
Units or Repeater Units that can be connected to one branch line using multi-
drop or T-branch connections.
■ Baud Rate of 1.5 Mbps
Note (1) This is the maximum number of Slave Units and Repeater Units com-
bined that can be connected to a branch line by using multidrop connec-
tions and/or T-branching. T-branching creates a sub-branch.
(2) The trunk line does not support branching. The trunk line and sub-trunk
lines support only multidrop connections.
(3) Branch lines support branching to sub-branch lines.
