Additional Information

• When there is a branch, Round Cable I, Round Cable II, Flat Cable I and Flat Cable II cables
cannot be used at a baud rate of 4 Mbps. This means you cannot use a Slave Unit with a

Mbps, the trunk line and the sub-trunk line must be no longer than 30 m.
• When a branch line has a sub-branch line, Round Cable II, Flat Cable I, or Flat Cable II
cables must be used either at a baud rate of 1.5 Mbps or 93.75 kbps.
• Maximum Length for Trunk Lines and Sub-trunk Lines
• When the lines are 30 m or less: Any combination of cable types and baud rates is sup-
ported except for Flat Cable II.
• When a distance longer than 30 m is required:
• Round Cable I: The baud rate must be 1.5 Mbps, with no branching. (The cable length can
be up to 100 m.)
• Round Cable II, Flat Cable I, or Flat Cable II: The baud rate must be 93.75 kbps. (The
cable length can be up to 200 m when unrestricted branching is used.)
