Communication Interface
The communication interface is two DB9 connector females.
Compatible with the RS232 DB9 pin without flow control, you can directly connect to the RS232
interface for communication by using the standard RS232 serial line without flow control. The
signals of the two DB9s are exactly the same, the user can use one DB9 to connect the control
host, and the other can use daisy-chain to expand the use of multiple drives.
