Simple null modem without handshaking

Simple null modem without handshaking

"only the data lines and signal ground are cross connected in the null modem communication cable. All other pins have no connection. An example of such a null modem cable without handshaking can be seen in the figure below."

    PCI104 Bus

    PCI-104 is the newest variation of the standard. PCI-104 removes the old PC XT / AT bus from the specification leaving only the PCI bus. The PCI bus connector is a 4x30, 2mm stack-through connector. PCI-104 cards may still reside in a stack with either PC/104 cards or PC/104-Plus cards.

    Instrumentation Design Office

    Instrumentation Design Office

    Instrumentation Design Office (IDO) is software for creating and managing industrial instrumentation and control systems design data and documentation including instrument datasheets, loop diagrams, termination diagrams, hookup drawings, I/O lists, instrument index, cable schedules, Bill of Materials and other reports.

    IDO consists of an integrated suite of software applications using advanced graphical user interfaces to a shared project or plant relational database. The user interface is intuitive and includes online help.

    Much of the data is created through automated functions & design rules, picklists and use of catalog data and data importation. IDO essentially automates production of design documentation from the database ensuring superior design integrity and significant reduction in manual data entry.
