NOTE: *For GSM modems a SIM card is required, supplied by your GSM network
provider:
• For SMS only, a ‘normal’ voice SIM card is required. This enables the controller to send SMS
messages to designated mobile phones upon status and alarm conditions.
• For a data connection to a PC running DSE Configuration Suite Software, a ‘special’ CSD
(Circuit Switched Data) SIM card is required that will enable the modem to answer an
incoming data call. Many ‘pay as you go’ services will not provide a CSD (Circuit Switched
Data) SIM card.
