connector CN3. Users can operate the servo drive through PC software supplied by Delta.
The communication connector/port of Delta servo drive can provide two common serial
communication interfaces: RS-232 and RS-485 connection. RS-232 is mostly be used but
is somewhat limited. The maximum cable length for an RS-232 connection is 15 meters
(50 feet). Using RS-485 interface can allow longer distance for transmission and support
multiple drives to be connected simultaneously.
