cable alone. Use the following formulae to calculate the max. network length
based on the lengths of thick and thin cable in the line.

Example Calculation
The results of the above formulae indicate that 250 kbps and 125 kbps can be
used as the baud rates for this configuration example.
Even when the above conditions are met, however, the current flowing
through the cables must not exceed the permissible current capacity. (Refer to
SECTION 3 Communications Power Supply Methods.)
Thin cable must be used in applications where space is restricted and thick
cable cannot be bent enough. In particular, use thin cable when wiring
devices mounted to DIN Track and the area between the DIN Tracks is limited.
In conclusion, we recommend the following usage:
