1   Function
 Communicate with computer master station system through medias like GPRS/CDMA, Lan TCP/IP, Radio modem to transfer data;
 Manage data abstractor terminal to collect data from meters connected.
 The data concentrator can also be used as an independent data terminal directly connecting to meters to collect and transfer meter readings to the master computer system station.

2   Application
     AMR (Automatic Metter Reading) component ,combine with CZL096-1C－24 or other EGATE AMR devices and computor system software,a AMR system can be established.
     Egate AMR system can not only be used at electricity meter reading but also be used at water,gas,and other meters.
  
3   Features
 High speed single chip computer design and embeded programming technology keeps the device has a high quality of steady and speed;
 Modual design makes the device can be easiely being upgraded and configured ;
 Flexible upward data channel,Meadia to master computer station can be easiely selected from ADSL,Data Modem,RS485,TCP/IP,GPRS/CDMA and Radio modem;
 Flexible downwarddata channel,  data concentrator can communcate with data abstracter terminal through mideas like PLC,mini radio modem RS485,mini busand so on.
 Power falure time can beautomaticaly recorded and data recorded could be remained in the device for as long as 10 years in case of power shutdown.
