Notes on Ethernet Communications
For ZM-300 (high-performance):
• To use Ethernet communications on ZM-300 (high-performance), use the 10BASE-T
connector (LAN) provided on the unit. It is not possible to use Ethernet or FL-net
(OPCN-2) communications by attaching the network module ZM-80NU/80NU2 to
ZM-300 (high-performance) at the same time. When ZM-80NU/80NU2 is mounted, the
10BASE-T connector (LAN) provided on the unit cannot be used.
• When using Ethernet communications with ZM-80NU/80NU2 mounted, the Web server
or e-mail function cannot be used.
For ZM-300 (standard):
• To use Ethernet communications on ZM-300 (standard), the ZM-80NU/80NU2 must be
mounted. When ZM-300 (standard) is equipped with the ZM-80NU/80NU2, it becomes
Ethernet-ready. In this case, however, the Web server or e-mail function is not
available.
IP Address for the ZM-300 Series
To enable Ethernet communications on the ZM-300 series, it is necessary to set the IP
address for identification of the ZM-300 series on the network. The IP address should be
set on the Main Menu screen of the ZM-300 series. For more information, refer to “Chapter
2 LCD Control Terminal Operations.”
