Internet Protocol and spread spectrum radios come together for remote
terminal applications. Semaphore, a
Nashua, N.H. subsidiary of Singapore-based CSE Global has introduced an
integral, spread spectrum radio option for its T-BOX LT compact remote
terminal unit (RTU)and SCADA system.
The product is said to be ideal for decentralized applications where its push and Web technologies enable high performance, economical implementation and operation. The spread spectrum radio cost effectively extends license-free communications to T-BOX LT applications in areas lacking cellular or land line telephone coverage.
The T-BOX product family is said to be the first Internet Protocol (IP)-based telemetry solution that enables complete integration of SCADA, control, and communications functionality in one rugged package. The LT model is cost effective for installations requiring up to 32 I/O points. The product family incorporates full Web server technology with SMS reporting and remote control to provide real-time access through a standard Web browser. Operators can receive alarms and communicate with their sites remotely using a mobile device such as a cell phone, laptop or PDA. Automatic alarm escalation allows key maintenance personnel to receive any unacknowledged alarms.
