Receive and process signals from RS232/482/422 printer or pager outputs. Signals are processed against a set of rules and where the rules are breached, alarms are generated and sent to the most appropriate responder. Example – Pager data is sent to the serial input module where it can be processed according to a number of pre-determined rules. Messages can be sent to a parallel printer for hard copies or output through serial ports in a variety of protocols or formats to the correct end user.
