Gu Mei CM-GPRS wireless data transmission communication module Functions CM-GPRS such as long-range monitor test,etc.

Apr 17th, 2017

CM-GPRS adopts transparent Transport Protocol to combine with GPRS as the communication module of wireless data transmission, apply with our company PLC to the automated system together, realize automated system and GPRS network, wireless connections of GSM network. Through the programming software, carry on long-range programming to PLC and diagnose, realize the download function on the procedure; Meanwhile, the cellphone subscriber can realize control to PLC through SMS message service, CM-GPRS is especially suitable for the long-range application of controlling etc. of the distributed system.

Characteristic of the products

1,Four global and common module frequently, support UNICOM, move the intersection of GPRS and network, ordinary the intersection of Mobile and Carlos (the intersection of MICRO SIM and Carlos) Namely available;

2,Use the module of technical grade, the characteristic is steady, quality is guaranteed;

3,Support the module restart automatically when not having data transmission for a long time ‘ Set up small at 600 seconds in order to forbid and restart the function automatically) ;

4,Data transmission is opened transparent;

5,Interface of standard industry (RS-232/RS-485) ;

6,Support the lasting online mode, have re-dialing and heartbeat function of circuit break;

7,Support the local disposition;

8,Support message machine format receiving and dispatching, support the long-range message to set up the module parameter (message set up the parameter and support cryptographic authentication, prevent the disabled user from setting up parameter and rubbish message to interfere with) ,Support the intersection of the remote server and end set up the parameter ‘ Can open / close this function) .
