Sample Data Communication Links
The SRM6200E-SLC’s versatility allows data communication links to be established using a variety of different
configurations. This, in turn, makes it possible to extend the range of the SRM6200E-SLC and get around obstacles.
Diagram 4 shows the most common and straightforward link, a master communicating to a remote in a dedicated link.
Diagram 4
Diagram 5 depicts how a link might be set up using a repeater. The Repeater may be sitting on a hilltop or other elevated
structure to link the Master to the Remote. In this setup it may be desirable to use an external omni directional antenna on
the Repeater; to extend the range Yagi antennas could be used on either or both of the Master and Remote.
Diagram 5
When a repeater is used the throughput is cut in half. Adding a second repeater (or more) ‘does not further reduce the
throughput, however it does increase the latency.
