Product Description:


Wiman WCT-805 is a smart Serial (RS232) to GPRS gateway, designed to transmit data transparently over GSM/GPRS cellular networks. Gateway is integrated with 32bit ARM Cortex, with application firmware to communicate with GSM/GPRS engine. It can operate as server or client mode; accept with dynamic IP or static IP. As compare to PSTN or GSM dialup or lease line, the WCT-805 with GPRS communication link provide a cost economical approach to achieve a always ON packetized data network. Easy to plug and play allows to migrating your traditional serial communication system to the advance GPRS link, without tedious application development and in depth knowledge on AT command or GPRS. You can view the device like virtual serial wire over the air that links all your remote equipments to the central PC/Server. It is a full transparent protocol in-dependent gateway. It is easy to configure, manage, and monitor remote devices on a private network over the Internet. The products also come with built-in I/O that can be configured to indicate the priority of events. The device can configured or update firmware over the air (OTA).
