gsm sim box voip gateway We-C13D2

Introduction:
With the development of wireless communication technology, CDMA products is used widely in the field of data transmission. In particular, there is a CDMA module further promote the development of this application. But the ordinary CDMA module is limit in using. It has no embedded TCP / IP protocol stack, so it is needed to provide TCP / IP for user. That is needed to use CDMA module embedded in the host computer system TCP / IP, which is a complex and tedious work for common MCU system. Sometimes even more than the workload of t itself. Wealth developed We-C13D2, which embedded the TCP / IP protocol stack, and

Simplifies the interface design. this equipment masks the complexity interface and interface protocol stack of mode anydata, and replaced by a common RS-232 interface or RS-485 interface or TTL level interface. Using simple AT + i command interface, and provides a more convenient power connector. We-C13D2 further is optimized the interface design and external servo circuit to suit for harsh industrial site. it is much more easy to use with the structure, beautiful appearance, stable performance.

Product Feature:
Powerful function
do not need PC dial-up network, a simple set of microcontroller devices can realize with the Internet to exchange data through the RS-232 or RS-485 or TTL level. no matter what happened, data terminal is always online even a sudden reason for power down or restart, We-C13D2 will automatically on line. In addition We-C13D2 can also set the timing detection for testing the external communication status. If long time no communication, the device to reset connections.
size
small size, this equipment can be connected with computer by RS-232wire; Standard DC power plug(Φ2.5mm chip).size of We-C13D2:73*55*19mm, NG:0.14KG.
Upgrade easily
We-C13D2 with Firmware online upgrade function, users can easily upgrade to higher versions of the software.
Powerful Expansibility
We-C13D2 has a powerful data transfer capabilities, pc and We-C13D2 can be connected to constitute a complete data communication system without other plug-in,
Strong anti-interference
Cold rolled sheet material shell, Durable, Can be effective against a variety of harsh environment；Anti-electromagnetic interference, and strong High-temperature heat capacity；plus a good power servo circuit, maximum make sure this equipment is working well in the substation and factory.
The external environment indicators
Operating temperature:-30-60℃
Humidity Range:≤90%
can work in strong electric magnetic environment (such as substations, etc.).
