VCTF cable:
Main line length: 100 m max.
Branch line length: 3 m max.
T otal branch line length: 50 m max.
Flat cable:
Main line length: 30 m max.
Branch line length: 3 m max.
T otal 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.)

VCTF cable:
Main line length: 500 m max.
Branch line length: 6 m max.
T otal branch line length: 120 m max.
Max. number of connecting nodes 32
Error control checks Manchester code check, frame length check, and parity check
Note: 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).
