6.4 LAN Port
External control via LAN is available. Use a serial communication cable to connect control devices such as
PCs and the MSD, and then control the MSD and get its status using commands. For character notation of
commands, refer to the “9 ASCII codes”. 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 setting of
LAN, see section “8.11 LAN Settings”.
