WR-1 REAR VIEW
This connection carries control data and power over CobraNet. PoE-enabled network switches or PoE midspan adapters must be used to
power the WR-1. These must be 802.3af compliant and must be isolated with respect to ground. The maximum distance between any unit
and an Ethernet switch is 100 meters (328 feet) when using copper cabling. Additional Ethernet switches and/or fiber-optic cable can be
used to further extend distances between units on a network.
If other network traffic shares an Ethernet switch with the Vocia network, a managed switch should be used with separate VLANs.
The following diagrams illustrate valid network connections for the WR-1.
