Branch line length: 3 m max.
Total branch line length: 30 m max.
(When flat cable is used to connect fewer than 16 Slaves, the main line can be
up to 100 m long and the total branch line length can be up to 50 m.)
Long-distance
communications mode
2-conductor VCTF cable:
Main line length: 500 m max.
Branch line length: 6 m max.
Total branch line length: 120 m max.
Flat cable, 4-conductor VCTF cable:
Variable branch wiring (total cable length 200 m max.)
(There are no limits on the branching format or main, branch, or total line
lengths. The terminator must be connected to the point in the system farthest
from the master.)

Error control checks Manchester code check, frame length check, and parity check

*1. A terminator must be connected to the point in the system farthest from the Master.
*2. The communications baud rate is switched using DM settings (default setting is 750,000 bps).
