4.3.8 Network Setup (continued)
A) General
Secured Applet: If checked, the LOGIN password is required to open “Readings” and “Chart” pages.
Title: Meter’s name [maximum of 16 alphanumeric characters]
B) Terminal Server
TCP/UDP*: The Meter supports TCP and UDP protocols (default is TCP). If UDP is selected, it can be configured either for Broadcast UDP or Directed UDP. In case of Broadcast UDP, the Meter will transmit the data to every node on the network. This can be accomplished if the Remote IP Address is set to 255.255.255.255.
The Broadcast UDP isa practical solution when one Meter needs to communicate with multiple nodes over the network. In the case of directed UDP, the Meter will transmit the data to a specific node on the network. This can be accomplished if the Remote IP Address is set to the IP address of that specific node.
Server Type: Continuous mode sends the temperature and humidity to the Ethernet, every two seconds. It is mainly used to send readings to a remote display. Command mode (default) needs a command to query the Meter to send the response back to querying device.
Forward CR: Forward CR can be enabled and disabled. If enabled the Meter will forward a <CR> along with the data to a network host.
Number of Connections: The range is from 0 to 5. If 0 is selected, the Terminal Server feature is disabled. This means that no network connection can be made to the Meter. If 1 is selected, only one network connection can be made to the Meter. Any number more than 1 would allow that number of network hosts to read from the Meter simultaneously (default is 5).
Port: Port number for TCP connections. Invalid ports: <500, >65536, 1000, 2002, 2003, and 7011.
C) Remote Access
Remote IP Address: The Meter can establish a connection to a remote device (e.g. an iLD Remote Display with an Ethernet embedded board) with this IP. Remote Port: (default 2000) the remote port number for the connection.
Ports 1000 (used for HTTPget, refer to Section 4.5), 2002, 2003, and 7011 are reserved for internal use.
Remote Access: ** Remote Access can be enabled and disabled. If enabled, the Meter can send its data to a remote node on the same network (the “Remote IP address” and “Remote Port” must be entered).
* TCP/UDP: when UDP mode is selected, Remote Access should be disabled and Remote IP and Port are the UDP remote listening IP and Port. If the Remote IP is set to 255.255.255.255, the UDP packet becomes a broadcasting packet which will allow any device listening to the Remote port to receive the packet.
** If Remote Access is enabled, Terminal Server is automatically disabled. Update: Saves and Updates any changes on the “Network Setup” page.
