2.2.1 Connecting MagWeb to a Local Area Network and the Internet
The MagWeb should be attached to the Local Area Network (LAN)/Ethernet network using the supplied 8-conductor CAT5 Ethernet cable. This connection is made directly to a network access device such as a router, or through a wall jack that connects to a network access device.
Info: The MagWeb is plugged directly into a wired Ethernet connection using the supplied Ethernet cable. The Ethernet cable run is limited to 100 meters in total length. The Ethernet cable must be connected to the Ethernet network and to the MagWeb device before the MagWeb is connected to the inverter.
Info: Ensure that the MagWeb is connected to an “always on” internet connection.
2.2.2 Connecting MagWeb to a Single Inverter
Use the supplied four-conductor remote cable to connect the MagWeb device’s TO INVERTER port to the Magnum inverter’s Remote port.
2.2.3 Connecting MagWeb to a Single Inverter and Remote Control
The MagWeb device, using the supplied cable, can be located near the remote or near the inverter. To mount the MagWeb device near the inverter, route the 6ft four-conductor remote cable from the inverter’s Remote port to the MagWeb device’s TO INVERTER port. Use the longer 50ft cable — supplied with the remote control — to connect the MagWeb device’s TO REMOTE port to the remote control. To mount the MagWeb device near the remote, swap the 6ft remote cable with the 50ft remote cable.
2.3 Configuring the Local Area Network
The MagWeb communicates with Magnum Energy’s servers by establishing an outgoing TCP/IP connection when data is received. At the default 30-second data interval, the MagWeb system will send approximately 2.5 megabytes of data per day.
By default, the MagWeb determines network configuration using DHCP or BOOTP. This information includes the MagWeb’s LAN IP address and router IP address. Most networks provide DHCP service and therefore the MagWeb usually does not require any configuration.
For details on configuring the MagWeb for non-DHCP networks or for special configurations, consult the troubleshooting section of this manual.

5.1 Troubleshooting Checklist
The MagWeb system is designed to be simple to install and easy to use. Most issues arise when a minor hook-up problem exists. Check the following items before seeking further help:
- Is the MagWeb Wired Ethernet connected to an “always on” internet connection?
- Did you connect the MagWeb’s Ethernet cable before connecting the remote cable to the inverter or powering the inverter up?
- Is it attached to a DHCP network to assign the address?
- Did you check your internet connection by plugging a laptop into your “always on” internet connection? (See instructions below)
- Is the inverter powered up and properly connected to the MagWeb device?
- Did you refer to Tables 4-1 and 4-2 to learn what the LED signals were communicating to you?
5.2 Troubleshooting Questions and Answers
What is this device on my network?
The MagWeb device allows remote monitoring of Magnum Energy inverters and accessories. Physically, it is a small black box with an Ethernet cable and three LEDs.
How does it communicate?
When the first data is received from the MagWeb device, a TCP/IP connection will be opened to Magnum Energy’s data server. This connection requires very little bandwidth – about 2.5 megabytes per day.
Why can’t I see my device on data.magnumenergy.com?
The most likely cause is a firewall or router blocking outgoing network connections. Contact your network administrator to resolve the problem.
I am a network administrator. How do I adjust network settings?
For most applications you do not need to adjust the network settings. The MagWeb will automatically receive its network settings using DHCP or BOOTP.
If you need to modify any settings, telnet to the device on port 9999.
What if my MagWeb cannot connect to the internet?
Unplug the Ethernet cable from the MagWeb and plug the cable into your laptop computer. Make sure any wireless and cell phone network connections are turned off.
Verify that you can reboot your computer, and then use a web browser to visit: http://data.magnumenergy.com/. If you cannot connect, then the network connection will not work for the MagWeb. The most likely problem is a network log-in requirement or a firewall that does not allow outgoing data connections.
