Detailed Description
CDMA DTU Modem is an industrial modem with RS232/RS485/TTL interface for wireless M2M solutions. We call it DTU in China, and actually it's a CDMA RS232/RS485 to Cellular Gateway IP modem. Short name for IP modem, or RS232 Serial CDMA Gateway.
The CDMA DTU Modem is a CDMA cellular modem with transparent transmission feature. Working under GSM/GPRS networks.
The GPRS DTU modem is a CDMA modem rs232 or rs485 port. Also there is TTL interface embedded version.
2.75G mobile communication technology (CDMA1x) has become widely used of industrials and utilities in recent years and many customers are seeking reliable, flexible and cost-effective data channel to build their information system. Many applications such as ATM, POS, SCADA and surveillance system will require data channels covered all country; this brings a bright future for CDMA data networks applications.Requirements towards information system are varied because of different features of numerous industrial applications. Mobile telecom service providers are required to provide industrial application solutions not only meeting common specifications and also individual special ones.
D130 CDMA DTU cellular modem is a data termination unit based on GPRS or CDMA mobile network. It provides data communication network for industrial applications. With the reliable, flexible and cost-effectiveness features, it can be utilized at many areas to provide the M2M communication channels.
D130 CDMA DTU cellular modem provides RS-232/RS-485/RS-422/TTL interface. Embedded with PPP, TCP/IP and DDPTM protocol, it converts the user data into CDMA 1x network and transmits the data into the customer’s data service center. With the professional designing, the D130 CDMA cellular DTU modem provides the plug and play, easy to use and maintenance features.
D120 Series CDMA M2M modem(data transmission unit) combined CDMA and Internet technology .It run IP procotol over CDMA networks . A non-interneted device can establish a internet connection by the PnP DTU. Internet-enable any RS232 device over CDMA cellular networks reliable solution for IP-based communication and CDMA network services low-cost, non-PC devices running M2M applications mediate the connection between a serial port device and the Internet eliminate the need for Internet programming and minimizes changes to the host application a real plug-and-play device.
