VW321A Interface：232 Interface：485 Interface：USB Interface：232TTL
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.
