SEI serial essernet interface EDP, bidirectional


The serial essernet interface can be used as a gateway to link remote computers that support the ESSER by Honeywell data protocol (EDP). The EDP version (bidirectional) with remote control options e.g. for the connection to a Building Management System (BMS). The unit includes a slot for an essernet module and is therefore a fully functional unit within the short circuit and open circuit resistant essernet.

  • Serial data rate 19.2 kBd
  • RS 485 interface on-board for a max. length of 1,000 m

Additional Information:
The essernet micromodule and the interface module either RS 232 (Part No. 772386) or TTY (Part No.772387) are not included and must be ordered separately in accordance with the required essernet type and the serial transmission standard. The optional interface module must be ordered separately and is a supplement to the serial essernet interface. It is plugged into the connectors provided on the main PCB. Depending on the required application, a TTY /CL 20 mA (Part No. 772387) or a RS232 / V.24 (Part No. 772386) interface module may be installed on the serial essernet interface. When using virtual control groups (PA/VA), a hardware output shall be provided on the FACP side per virtual control group, e.g. through the output of an esserbus coupler.To avoid any kind of problem, please contact the International Sales Support for advice before quoting or installing the serial essernet interface!
