Error control checks

Manchester code check, frame length check, and parity check

Note: 1. An external terminator must be connected.

Note: 2. Controlled by DM area setting (default setting: 750 kbps).

Note: 3. 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.

Note: 4. 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.
