Changing the p250’s IP address
Important Note: You must carefully record and store the new IP address for future reference.
After the factory-default IP address is changed, it cannot be remotely reset.
To change the p250’s factory-default IP address, perform the following steps:
1. From the p250 web page, click the Configure IP Address link.
2. The Change IP Address page loads (Figure below), displaying the factory default IP Address,
Subnet Mask and Gateway addresses.
Figure 4-36 p250 Change IP Address page.
3. Change IP Address, Subnet Mask and Gateway addresses as required. Be sure to record these
address changes in a safe location and then click the Submit button.
4. To revert back to the factory default IP settings, simply click Submit when the Change IP Address
page opens.
5. Remove DC power from the laser, wait 30 seconds, and then re-apply 48 VDC power.
6. Launch your web browser, type the new IP address (http://xxx.xxx.xxx.xxx), and then press
Enter. The p250 home page will appear as shown back in previous figure. To reach the event log
page, enter “http://xxx.xxx.xxx.xxx/service.html” (without the quotes); where xxx.xxx.xxx.xxx is
the new IP address.
Alternate Ethernet connection
In situations where it is necessary to isolate the p250 laser from your internal IT network, but still access
the p250 web page from a networked control computer, you can connect the p250 laser to the
networked computer using a USB to Ethernet adapter. Devices like the TRENDnet TU2-ET100 USB to
10/100 Mbps Adapter allow your networked computer to access the p250 web page over the
computer’s USB port, which isolates the laser from your computer network. In this case, use a crossover
Ethernet cable between the p250 laser and the USB to Ethernet adapter.
