[Table 5.3] Increasing connections
Note:
If any command is not sent from the PC side to the MSD for 30 seconds, the MSD disconnects the connection
to avoid the limitation problem on the number of connections. As a result, the connection needs to be
established again from the PC side after the current connection of the PC is disconnected. (Since the number
of ports in the MDS series is eight, if the PC is turned off while it is connected, ports are occupied permanently.
To prevent this, the connection is disconnected if no communication command is sent from the PC side.)
