    Description

    PD8, Interface Converter RS-485/ETHERNET

    The RS-485/ETHERNET converter PD8 from LUMEL†allows master devices to transmit data via an ETHERNET network to the devices with RS-232 and RS-485 interface.

    The converter has three operating modes:
    ††† + RealPort network service,
    ††† + serial bridge service with the UDP protocol and
    ††† + TCP/IP Socket service.

    In the first and third mode, the switching master device of the system is a PC using ETHERNET interface. In the second mode, the converter works with a device with Master function and RS-232 and RS-485 serial interfaces.

    The converter PD8 to work with RealPort network service requires the installation of a virtual serial port driver on a PC with Microsoft Windows. Thanks to the PD8 type converters, this driver provides the existing master systems, i.e. programs like LUMEL Heat and LUMEL Process, the ability to transmit data between devices with RS-485 or RS-232 interface using ETHERNET network When used in this way, the converter allows to work with one master computer in the given time. When using PD8 to support MODBUS and LUMBUS industrial protocols - its correct interaction with master systems installed on a PC depends on the built-in mechanisms to control time intervals between the received transmission characters.

    Using PD8 in the second mode, the RS-485 bus can be expanded with successive segments using additional PD8 converters and ETHERNET local network. Properly configured, one pair of converters allows to build a system working in the serial bridge mode. It is also possible to configure their operation in ?one-to-several? mode (as a set including up to 65 converters). Function 2 of the converter operates in the ETHERNET local network with UDP datagram protocol support.

    Operation in the third mode†is very similar to the converter working with RealPort network service except that it is not required to install software virtual serial port driver on a PC with Windows. Communication between a PC and PD8 converter is via TCP Socket mechanism.
