The VW321A series wireless module provides the capability of a short range, reliable wireless point-to-point, point-to-multipoint and mesh network RF data communications link. They can be used in a variety of data communications applications that require a simple to use invisible data link.

The wireless modules are designed to operate in the unlicensed ISM frequency band (315MHz/433MHz/868MHz/915MHz ISM band) and are therefore acceptable for use in many countries.


Features:

-4 Operation modes: Transparent mode, Transparent secured mode, Addressed mode and Addressed secured mode.

-Repeater supported

-Integrated wireless link protocols

-Deep sleep mode (Power down mode) /Wakeup Control

-Server-Client mode

-Broadcast Multi-drop mode

-Easy configuration by AT commands.

-Easy configuration with a user friendly control panel on PC.
