NMEA0183 standard translation 1 --

INTRODUCTION: The IEC 61162, an international standard, consists of four digital interfaces for navigation, radio communication, and system integration. IEC 61162-1 multiple transmitting accepted by IEC 61162-2 single transmitting multiple accepted, high-speed transmission IEC 61162-3 multiple transmitting multiple accepted-Serial Data instrument network under consideration) IEC 61162-4 multiple launch acceptance-the IEC Technology Committee for the interconnection of marine systems specifies 80 interface standards. This information is intended to meet the needs of most users, but users should realize that with the change of technology, interface standards should also change. If you feel anything wrong, please notify us in time. This is the full version of IEC 61162-1. This version is very similar to NMEA0183V3.0.1. It contains 3 notes available for earlier releases: Additional requirements for the PAS61162-100 for IEC 61162-1 UAIS. The PAS61162-101 modifies the statement and demand for IEC61162 and the additional demand for the PAS61162-102 for the maritime data record. The second version includes detailed vessel device definitions in IMO (International Maritime Organization) and statements suitable for their communications. Currently, Practice specifies the sentence format standards for individual devices. Therefore, the standard statement format for the first five versions) and the minimum requirement statement for attachment A are included. Note: Device reflection and behavior should be within the scope of this Standard and should be included in individual device standards, such as warning handling. This version introduces the two types of start statement segmentation. Traditional Separator"$The split statement is called a parameter statement. New separator "!" A special purpose encapsulation statement. This example is applied in sentence 9 in the second version of sentence 7) has been extended to describe the type.In Sentence 8, Version 2, sentence 6) The statement list has been updated to include all the statements. They are developed in three publicly available descriptions, and the new dimming statement DDC ), NAVTEXNRM and NRX), the rudder direction ROR), the header to THS) and the user identity code to transfer UID ).As an empirical result, the statements given in the PAS61162-102 are for marine data recording; ALA, AKD, DOR, ETL, EVE, FIR, GEN, HSS, PRC, TRC, TRD, WAT has been modified in this version. 1.

Data format protocol (Data format protocol)7.1 charactersAll transmitted data is interpreted as ascii characters. The most important 8-character should also be transmitted as 0D7 = 0)7.1.1 Reserved WordsReserved Words include ascii characters, displayed in 8.1 Table 1 ). These characters are used for special format purposes, just like statements and field delimiters, except for code segmentation, will not be used in data fields.7.1.2 valid charactersValid character set contains all printable ascii characters HEX20 to HEX7E) except those reserved words. Valid character set is given in 8.1Table2 ).7.1.3 undefined charactersAscii value, neither reserved words nor valid words, will not be transmitted at any time.It is required when transmitting an 8-bit character defined in the ISO/IEC8859-1, which is a reserved word Table1) or if no column is listed in Table 2 as a valid character in a proper statement or text Statement), the three characters will be used.The reserved character '^' (HEX 5E) followed by two ascii characters 0-9, A-F) represents the HEX value. For example:---- 127.5. 127.5 ^ F8---- <CR> <LF> equivalent to ^ 0D ^ 0A---- ^ Equivalent to ^ 5EIEC60945 indicates that, as a minimum requirement, English will be used for control and reality. Other languages and characters will only be supported by TUT statements.7.1.4 character symbolsWhen a measurement unit is defined in the standard at your own discretion, it indicates the data field type, statement type, and so on. They will be interpreted through characters symbolic in 8.1 Table 3 ).  7.2 DomainsA field contains a valid string or is empty. Locate in the appropriate separator. 7.2.1 address domainAn address domain is the first domain in a statement, followed by "$" or "!". Delimiter. It serves definition statements. The "$" separator specifies the statement, which conforms to the traditional parameterized and segmentation domain composition rules and is described in 7.3.2. "!" The delimiter specifies a statement that complies with the special purpose encapsulation and non-segmentation domain composition rules. The description in 7.3.3. Character in the address domain is limited to numbers and uppercase letters. The address field is not empty. Only the following three types of domains will be transmitted. 7.2.1.1 the general address bar consists of five numbers and uppercase letters. The first two characters are the transmitter IDs listed in 8.2 Table 4 ). The sender identity defines the nature of the transmitted data. Devices with the ability to transmit data from multiple resources will transmit the appropriate transmitter identifier such as a device both GPS accepted and LORAN-C accepted will transmit GP when location is GPS positioned, LC when the location is LORAN-C positioned, IN for integrated navigation will be used if the location is a combination of LORAN-C and GPS ). The device holds the re-transmitted data from other resources will use the appropriate identifier such as GPS to accept the transfer header data will not be transmitted $ GPHCD unless the compression header is the exact device from the GPS signal ). The last three characters generally define the data format and type. The statement format is listed in 8.3.
