‘GPRS’ defines main parameters for FMB630: destination servers Domain (can be entered either IP or domain name) and port. Also both TCP and UDP protocols are supported. Server Response Time defines the time how long device will wait for response from server before device denies the connection between FMB630 and server. Server 2 is used as dublicated server (not back up server).
Some operators use specific authentication for GPRS session – CHAP or PAP. If any of these is used, APN should be entered as ‘chap:<APN>’ or ‘pap:<APN>’. I.e. if operator is using APN ‘internet’ with CHAP authentication, it should be entered as ‘chap:internet’. Information about APN and authentication type should be provided by your GSM operator.
