Constricted Topology: Not Recommended
In some cases, PowerMonitor W250 devices might be located far away from the
PC Receiver and all data from the network has to travel over a single path. Such a
situation creates bottlenecks and increases the risk of losing data packets.
We recommend avoiding such topologies by adding additional routers to provide
parallel links to the PC Receiver.

PC Receiver Location and Connection
Consider these suggestions when locating your PC Receiver:
• When possible, locate the PC Receiver near the geographical center of the
RF network.
• It may be helpful to have a notebook personal computer for startup,
diagnostics, and troubleshooting.
Follow these steps to connect the PC Receiver.
1. Apply power to the PC Receiver by plugging in the DC power supply
adapter.
We recommend that you apply power to the PC Receiver prior to applying
power to any PowerMonitor W250 devices.
