In environments with a lot of electrical noise, (for example, close to a high voltage cable, a frequency
drive, or a light control device), a shielded twisted pair cable is recommended.
A shielded twisted pair with braid is recommended for the link between two barns. To avoid ground loop,
ground only one side of the Ethernet cable on the Ethernet switch. Normally, the Ethernet standard does
not recommend to mix unshielded twisted pair cable and shielded twisted pair cable pattern. The goal
here is to break the ground loop.
Figure 3-1 Typical EDGE Network using Ethernet Cables
Wireless Network (WiFi)
WLAN Network
AP/Cumberland does not provide Ethernet network components. Ensure to purchase network compo-
nents according to the implemented Wireless technology.
The physical EDGE System WiFi network consist of the following parts:
• Router with WiFi or Router without WiFi and using access points
The router is the DHCP server for the WiFi network and is also the bridge with the customer network.
Installation Options:
The WLAN network can be setup to reach outside Ethernet cables or wirelessly using a Cellular based
network to reach an Ethernet service provider (WAN).
Depending on the option you choose, the planning and installation will be different. For an Ethernet setup,
make sure there is access to high speed Internet.
Redundant Controller and WLAN Network
A redundant Main Controller is used in case the Main Controller Master fails. Use of a redundant Main
Controller will determine its communication scheme:
