SmartDisk System Components External Communication with SmartDisk System Data Transmission Module (DTM) The DTM wirelessly transmits the electrical “changes of state” of a pressure event sensor (e.g. Burst Alert® Sensor or pressure switch) immediately. The DTM may power most sensors using its integral replaceable battery (up to five-year DTM Module battery life). Optional external DC with Standard Internal Antenna power with battery back up or optional solar power can be used. A DTM can be installed up to 100 ft (30 m) from its sensor using shielded cable. All receiver modules are provided with...

Building a Wireless Sensor System The freedom of wireless technology gives SmartDisk the flexibility to adapt to local installation conditions. Up to 32 DTM or ATM transmission modules can be programmed to a single receiver. Using RS232/RS485, up to 32 receivers and user devices can be connected together with communication by Modbus protocol. The modular construction of the SmartDisk system makes application of the technology both simple and cost effective. Basic guidelines to follow are: All applications require one transmitter (DTM or ATM) per sensor (unless wired in series with DTM). All applications...
