5.3 Cable Connections
The MVI71-MNET module has the following communication connections on the
module:
ƒ One Ethernet port (RJ45 connector)
ƒ One RS-232 Configuration/Debug port (RJ45 connector)
5.3.1 Ethernet Connection
The MVI71-MNET module has an RJ45 port located on the front of the module
labeled "Ethernet", for use with the TCP/IP network. The module is connected to
the Ethernet network using an Ethernet cable between the module’s Ethernet
port and an Ethernet switch or hub.
Note: Depending on hardware configuration, you may see more than one RJ45 port on the
module. The Ethernet port is labeled "Ethernet".
Warning: The MVI71-MNET module is NOT compatible with Power Over Ethernet (IEEE802.3af /
IEEE802.3at) networks. Do NOT connect the module to Ethernet devices, hubs, switches or
networks that supply AC or DC power over the Ethernet cable. Failure to observe this precaution
may result in damage to hardware, or injury to personnel.
Important: The module requires a static (fixed) IP address that is not shared with any other device
on the Ethernet network. Obtain a list of suitable IP addresses from your network administrator
BEFORE configuring the Ethernet port on this module.
Ethernet Port Configuration - wattcp.cfg
The wattcp.cfg file must be set up properly in order to use a TCP/IP network
connection. You can view the current network configuration using an ASCII
terminal by selecting "@" (Network Menu) and "V" (View) options when
connected to the Debug port.
