Lan Port; The Number Of Tcp-Ip Connections - IDK MSD-804FD Series Command Manual

1.2 LAN Port

The MSD-804FD controls peripheral devices externally using LAN. Connect control devices such as
computers and the MSD-804FD with LAN, and then control the MSD and acquire the status using commands.
For command character notations, see "2 ASCII code". For control using commands, use ports 6000 to 6999,
1100, and 23. Connection will be disconnected if no communication for 30 seconds or longer after connection.
For LAN settings, refer to "8.11 LAN Settings" in the Users Manual.

1.2.1 The number of TCP-IP connections

The MSD-804FD can connect up to eight connections (eight ports) at a time. If the MSD is controlled from
nine or more computers, they may not be connected to the MSD.
For nine or more connections, use your software to establish and close TCP-IP connections for each sending
and receiving communication commands. By doing so, ports are occupied and released in the MSD side so
that logically eight or more connections (8 ports) can be connected.
