Chapter 1

Introducing the WLS-IFC

Overview: WLS-IFC features

The WLS-IFC is a USB-to-wireless interface module that is supported under popular Microsoft® Windows®
operating systems. The WLS-IFC is fully compatible with both USB 1.1 and USB 2.0 ports.

The WLS-IFC device operates as the interface between a computer and one or more remote WLS-Series
devices. The remote devices can be located up to 150 feet (50 meters) indoors, or up to ½ mile (750 m) outdoors
from the WLS-IFC.

You configure the network parameters required for communication with remote devices. All parameters are
software selectable. Only devices with the same parameter settings can communicate with each other. Once you
configure the WLS-IFC to communicate with remote devices, you can connect it to different computers without
having to configure the network parameters.

The WLS-IFC has LEDs that indicate the status of communication over the wireless link. An LED bar graph
shows the fade margin of signals received by the WLS-IFC.

The WLS-IFC is a standalone plug-and-play device which draws power through the USB cable. No external
power is required. All configurable options are software programmable.

WLS-IFC block diagram

WLS-IFC functions are illustrated in the block diagram shown here. The diagram shows the WLS-IFC
communicating with three remote WLS devices. There is no limit to the number of WLS devices that the WLS­IFC can communicate with.
