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.

Features: 1.2.4g bidirectional wireless rf module 2.Automatic frequency modulation; excellent anti-jamming capability 3.250k wireless transmission rate 4.30 meters effective open distance. The scanner will beep three times when it exceeds the effective distance or fails to transmit data. 5.Exclusive machinery id 6.User-defined id is convenient to distinguish the data sources. 7.Easy to match with 8.The inventory mode is easy to be used. It can store 500~10000 bar codes. (custom made if more than 500 bar codes) 9.It can turn to standby mode automatically. Standby current is less than 10ua and that makes the battery standby time much longer. 10when the battery voltage is 3.5v, the scanner will have a long beep sound every time it is power on or scanning. 11special charging circuit makes sure the charging safety.
