  • Page 5: Communication

    Communication In General The DCU 305 Control Unit has built-in support for communication towards a control panel. The control panel can display an overview of one or several DCU 305 panels. This control panel can be one of several types on the market. We have standardised on a suite of panels, but others can be used.

    When the total distance from the Slave panel to the DCU 305 R2 is longer than 8 meters. • When communicating to more than one DCU 305 R2. This is often referred to as a multidrop network. This is summarised in the table below.
  • Page 7: Communicating To One Control Unit Only

    Longer distances For longer distances (<1200m), we employ an RS-232/RS-422 converter box. These are available from several vendors. We recommend using the Phoenix PSM-ME or ICPCON units. <1200m <8m Master: DCU 305 R2 Factory- ID: 11 RS-422 RS-232 Link E1071 Etc.

    1-237, but it must be unique in the network. Note! If using the Auto-Maskin SP 305 slave panel, the E-615 or E- 910 type panels, the ID-number must be less than 32, as this is the highest supported ID-number on these panels.
  • Page 9: Rs-232/Rs-485 Signal Converters

    RS-232/RS-485 signal converters In a multidrop network, RS-422/RS-485 signals must be used. The signal converters above convert the RS-232 signals in the DCU 305 to RS-422. The RS-422/RS-485 signals can be used for distances up to 1200 meters. For longer distances, RS-422 repeaters can be used. We recommend using the Phoenix or ICPCON converters.

    Cabling Various RS232/422 converters A number of different RS232/RS422 converter modules exist. The following describes the connections for two popular types: • Phoenix PSM-ME • ICPCON I-7520AR These will be referenced as Phoenix or Icpcon respectively. Wiring DCU 305 – Phoenix Converter The cable between the DCU 305 and the Phoenix converter can be max 8 meters long.

    Available signals for communication The following lists the available signals in the Control Unit. Slave panels and Supervision Systems (Wheelhouse panel in general) can access all status bits in any random order. Status A one (1) means an activated signal unless otherwise stated.
