DP11 Network Controller

  
The DP11 is a network processor for controlling a network of Minicoms and Doorcoms.  The DP11 is designed to be attached to the serial port of a PC or a modem and has its network port connected to a RS485 network of field processors.  The DP11 handles all the messaging between field processors.  It also is responsible for alarm pre-processing and will do automatic dialouts to pagers and other devices accepting the PET protocol.  Telstra, Optus and Hutchinson communications have certified the PET protocol as compliant.  Alarm conditions can be printed on a local printer and are also sent to the attached PC for display to the operator.  The DP11 will not acknowledge alarms, this is the responsibility of the operator.

The DP11 also has 4 digital inputs that can be configured to send global messages to all devices on the field network.  These inputs are typically designed for use for fire alarm warnings.
