The Internat
21、ional Standard defined herein provides: a method by which machines and computer systems conduct their exchanges of data; a method by which computer systems can initialize such parameters on machines as the manufacturers thereof allow; a method by which machines can initialize computer systems with i
22、nformation that the systems can use for various purposes; a method by which a machine can inform a computer system as to what information it wants to receive, thus allowing machines to define new interfaces dynamically; a standard set of records and device types that are used to communicate agreed u
23、pon sets of information. The last feature listed above requires that this International Standard be amended on a regular basis, as the need for new data elements is inevitable. EN ISO 16284:2006 (E) 5 1 Scope This International Standard establishes a method by which machines and computer software sy

45、3.7.1.3 packet timeout timeout which applies to the reception of a packet 4 Overview The strategy used in this International Standard for the exchange of data between devices and hosts can be expressed as follows. A machine used in the fabrication of ophthalmic lenses (a device) sends a request to a
46、 computer system (a host), indicating a need to do one of the following: initialize information to identify the device, software versions, model numbers, etc.; upload to the host, information for it to store and/or use in the processing of ophthalmic prescription orders; download from the host, info
47、rmation required by the device for it to perform its tasks. EN ISO 16284:2006 (E) 10 Communication can be initialized in two ways. The device may begin an initialization session or the host can force the device to do so by refusing to accept a normal request and asking for initialization via a speci
48、al error response. For upload requests, the host acknowledges the request and the device sends its data, the receipt of which the host acknowledges. For download requests, the host responds to the request with the data requested. The variable-length packets of data that comprise this exchange consis
49、t of a series of records, each of which contains data and a label identifying the data. This International Standard defines a set of labels and characterizes the data associated with each. This set of labels shall be expanded as needed in the future. An exchange of packets related to a single job is called a session. The structure of these sessions and the packets of records of which they are comprised is the subject of this International Standard. Although this International Standard was conceived as being implemented on point-to-point RS-
