| Seriol Remote Terminal Units
Programmable Telemetry Controllers for industrial monitoring control and data acquisition.
Sercal - Programming and Application Development
The Sercal programming language provides a set of software tools to design, develop, install and debug complex application specific functions. Common to all SERIOL products, the language is similar in appearance to BASIC but can directly access analogue and digital, inputs and outputs. The programming language is complemented by a powerful on-line debug and diagnostic utility for real time program development. A remote PSTN version for use with telephone autodial, autoanswer outstations is available.
