'''''CNT''' -'' an oscillatory circuit, thanks to which the basic level of filling of the sensor measuring tubes with fuel is calculated. This level is converted to a final value determined by the data interface. | '''''CNT''' -'' an oscillatory circuit, thanks to which the basic level of filling of the sensor measuring tubes with fuel is calculated.

''''' | '''''Data transfer protocol''''' - a set of specific logical-level rules or conventions that govern the exchange of data between different programs or devices. For TD-150, the main transmission protocol is '''LLS via the RS-485 interface'''. | ||
''''' | '''''Data transfer mode''''' - this is a type of boundary between two objects or nodes, which are regulated by a special accepted standard and implemented using established methods, tools and rules. TD-150 has the following operating modes: | ||
* '''RS-485 ( | * '''RS-485 (Passive and Active)''' | ||
* ''' | * '''Analog''' | ||
* ''' | * '''Frequency''' | ||
''''' | '''''Interface''''' - a physical connection method and/or a set of software tools that allows data to be transferred between two or more devices. | ||
'''''RS-485''''' - | '''''RS-485''''' - digital data transmission mode. The sensor waits for a corresponding request from the receiving device. Works using the LLS protocol. Based on CNT, a value is generated in conventional units of the selected range (1-1023 cu or 1-4095 cu) | ||
''' | '''''Converter''''' - digital converter RS-485 to USB ([https://www.fmeter.ru/download/_ftp/escort_c-200m/%D0%9F%D0%B0%D1%81%D0%BF%D0%BE%D1%80%D1%82%20%D0%A1-200%D0%9C.pdf?v=200320145441 С200М] или [https://www.fmeter.ru/download/_ftp/escort_c-200m/%D0%9F%D0%B0%D1%81%D0%BF%D0%BE%D1%80%D1%82%20%D0%A1-200M2.pdf?v=150323104901 С200М2]) for configuring wired sensors. | ||
'''''Активный (периодический) RS-485''''' - разновидность вышеуказанного режима работы, при котором датчик, не ожидая запроса от приемника, сам передает пакеты с данными каждые 2 секунды. | '''''Активный (периодический) RS-485''''' - разновидность вышеуказанного режима работы, при котором датчик, не ожидая запроса от приемника, сам передает пакеты с данными каждые 2 секунды. | ||
