Assign an IP Address

3.0ASSIGN AN IP ADDRESS

After connecting the OpenComms EM device to your network, the next step is to identify the device to the network by assigning an IP address.

Consult Your Network Administrator

Consult your network administrator to obtain an IP address that is appropriate for your network, as well as a subnet mask and default gateway address. When your device is assigned a new IP address, it is saved in the Electrically Erasable Programmable Read-Only Memory (EEPROM), meaning the unit will retain its IP address even after power is recycled.

Select a Method

There are three methods of assigning the IP address, as listed in Table 4, depending on your net- work’s method of assigning IP address (static or dynamic) and your computer’s operating system (OS). The IPSET.exe program is included on the CD that came with your unit.

Select a method and refer to Table 4 to determine which instructions to follow.

3.1Use IPSET.exe to Assign an IP Address

If your network uses static IP addresses and your computer has a Windows operating system, you may use the IPSET.exe program included on the CD that came with your unit.

NOTE

These steps must be done on the same network segment where the OpenComms EM is connected.

To do this:

1.Insert the OpenComms EM CD in the CD drive.

2.Click on the Start button, then on Run.

3.In the Run window, click on Browse to locate the file IPSET.exe on the CD, highlight the file name and click Open.

4.In the Run window, click OK. The IPSet window opens, as shown at right.

5.In the IP address box in the Target area, enter the IP address for your unit.

Note: The IP address must be unique on the network—not assigned to any other device.

Enter a unique IP address

Subnet mask

Default gateway address

Enter the unit’s MAC address (look on bottom of unit)

Apply button

6.Enter the Subnet Mask of your network in the Subnet box. (Depending on your IP address, some or all of the Subnet Mask might be entered automatically after you enter the IP address.)

7.Enter the default gateway address in the Default box.

8.In the MAC address box, enter the MAC address of your device.

Note: The MAC address is found on a sticker on the bottom of the device.

9.Click on the Apply button. If the device identification is successful, the message “Successfully set IP address” appears in the Status box. (If not, the message “No response from target” appears in the Status box.)

10.Click on the Close button and proceed to 4.0 - Web Interface Overview.
