5.10.1.5 Ethernet
This option allows the user to configure the unit for Ethernet connection. To set up the Ethernet option use
the UP (
↑) or DOWN (↓) Arrow Keys to highlight “Ethernet” on the Com Port menu and press ENTER.
There are three menu items: “IP addr”, “Subnet mask”, and “Name Server”.
a. IP addr
The IP address is a unique address used by the network to get messages to or from the Recorder.
See your network administrator to obtain a valid IP address. Use the UP (
↑) or DOWN (↓) Arrow Keys
to highlight “IP addr” and press ENTER. Use the multi-page alphnumeric keypad to enter a valid IP
address and then press ENTER.
b. Subnet mask
The Subnet mask determines what IP addresses are considered to be on the same subnet. A typical
value for a Subnet mask is 255.255.255.0. Use the UP (
↑) or DOWN (↓) Arrow Keys to highlight
“Subnet mask” and press ENTER. Use the multi-page alphnumeric keypad to enter Subnet mask and
then press ENTER.
c. Name Server
This option is used to set the IP address of the PC running the name server used in the “Guardian”
software package. If you don’t have this software, this may be left blank. Use the UP (
↑) or DOWN (↓)
Arrow Keys to highlight “Name Server” and press ENTER. Use the multi-page alphnumeric keypad to
enter the IP address of the PC running the name server and then press ENTER.
NOTE: Whenever any of the above options are changed, the Recorder must be restarted before the
changes will take effect.
When using the optional Companion Software, you must first make a connection using the E-Bridge
program before using the Ethernet to connect to a Recorder. Double click on the E-Bridge icon. Double
click on its icon on the system tray (or right click then select enable) to open the window. If the Recorder
you want is not in the list, add its IP address and a description then press the save list button so the
information will be remembered next time. Select the IP address you want to connect and then press the
connect button. The Connect column should change from No to Yes.
NOTE: Only one Recorder can be connected at a time.
The Number of Retries and Ethernet timeout are the only other settings in this dialog box that have any
effect on the Ethernet connection. Once a connection is made, the communications are the same as for
a serial port. If communications stop, you may have to reset the connection by right clicking on the E-
Bridge icon on the system tray and selecting Reset.
5.10.2 Network ID
The Network ID, or unit address, assigns a user programmed Recorder ID number for use in multidrop Modbus
environments.
To Program the Network ID use the UP (
↑) or DOWN (↓) Arrow Keys to highlight “Network ID”. Press ENTER
to invoke the Network ID menu, “net id ÎXXXÍ” will be displayed. Use the Numeric Keypad to enter a Network
ID between 1 (default) and 255. When the correct Network ID is displayed, press ENTER and the display
returns to the “Network ID” prompt. Even if you are not using the unit in a Modbus environment it still requires
a network ID to communicate with the Companion Software.
