| The ADAM-4581 1-port GSM to RS-232/485 Wireless Data Gateway product provides GSM CSD data communication as well as SMS service through the interface with the 2-band GSM (900/1800) module for applications in facility management systems, water/wastewater monitoring, pipeline monitoring, unmanned telecommunication facility monitoring, surveillance, as well as others. The ADAM-4581’s interface uses the industrial device standard RS-232/485 with auto-flow control. ADAM-4581’s built-in intelligent SMS communication capability provides communication transparency for RS-232/485 ASCII data and GSM AT command conversion. Users are guaranteed GSM AT commands and SMS for communication are always available. ADAM- 4581 converts ASCII data or commands into a message in SMS or GSM data mode and can also convert this message back to an ASCII data/ command at another site’s ADAM-4581. If an urgent alarm or event happens in a field site, through the ADAM-4581’s eight TTL digital inputs, the ADAM-4581 could instantly send a short message to a control station, mobile phone or wherever else the alert is needed. |
