Framing error что за ошибка
RS-232 framing error
New here, so a bit about myself first:
I am a fire alarm commissioning engineer by trade, but like to mess with electronics as a hobby. my main area of interest is integration between various systems (which is one of the reasons I like doing fire alarms, as they interface with most systems in big buildings) and have recently started getting more involved with serial comms to interface systems, rather than boring relay contacts.
In my house, I have an 8X8 audio/video matrix switcher, this connects the stereo systems in all the rooms to each other so that i can patch any rooms audio to any of the other rooms in the house. This switcher has an RS-232 serial port on the back, which I’m hoping I can interface to either a PI or an arduino, so that I can control it via a web interface.
After a while searching, I found the protocol for it online. but things haven’t gone so smoothly after that unfortunately.
Currently I’m just using a usb-232 converter and a null modem cable, along with a program called 232 analyser on my laptop. I can read data fine, and send data to the unit. but it keeps spitting back a ‘framing error’ message.
I’m not sure what I’m doing wrong, please could someone advise? this is the first time I’ve really used serial so pointers would be cool. One thing i did think is that the protocol specifies:
but my analyser program only lets me set the baud rate, data bits, parity, stop bit, and data format. not start bit. could that be my issue? and if so how do i get around it? thanks so much in advance!

Framing error что за ошибка
Ошибки на интерфейсах есть двух разновидностей: ошибки входа и ошибки вывода.
Ошибки входа бывают следующие:
• Errors: Суммарное количество отмен входящих кадров и ошибок FCS.
• Drops: Количество пакетов, которые дропнул диспетчер ввода-вывода пакетов на ASIC’е. Если интерфейс перегружен, этот счётчик увеличивается на единицу каждрый раз, когда RED дропает пакет.
• Framing errors: Количество пакетов, полученных с неверной контрольной суммой (FCS).
• Policed discards: Количество отброшенных пакетов, так как они были не распознаны или не подпадали под выборку. Обычно, это поле показывает протоколы, которые не обрабатывает JUNOS
• L3 incompletes: Количество отброшенных пакетов с битыми L3-заголовками. Например, поле кадра «destination IP» меньше 32-х бит.
• L2 channel errors: Количество событий, когда конфигурация не смогла назначить логический интерфейс для входящего пакета.
• L2 mismatch timeouts: Количество искаженных или мелких пакетов, которые не смогли быть прочитаны.
• FIFO errors: Количество FIFO-ошибок на входе, о которых сообщил ASIC на контроллере интерфейса.
. Это значение должно быть строго НОЛЬ. Ненулевое значение указывает на аппаратный сбой контроллера.
• Resource errors: Суммарное количество дропнутых пакетов.
Ошибки вывода бывают следующие:
• Carrier transitions: Количество переключений интерфейса из состояния «выкл» в состояние «вкл». В норме вещей, эта цифра растёт ОЧЕНЬ медленно (по количеству выдёргиваний патч-кордов, отключений «ответного» устройства или перегрызаний кабеля крысами). Если это число растёт быстро, то у вас «флапает» интерфейс по причине некачественного кабеля, плохого контакта или аппаратного сбоя.
• Errors: Суммарное количество отмен исходящих кадров и ошибок FCS.
• Drops: Количество исходящих пакетов, которые дропнул диспетчер ввода-вывода пакетов на ASIC’е. Если интерфейс перегружен, этот счётчик увеличивается на единицу каждрый раз, когда RED дропает пакет.
• Aged packets: Количество пакетов, которые оставались в оперативной памяти маршрутизатора слишком долго и были отброшены. В норме вещей, это число должно быть ВСЕГДА равно нулю. Ненулевое значение указывает на аппаратный сбой или баги в софте.
• FIFO errors: Количество FIFO-ошибок на выходе, о которых сообщил ASIC на контроллере интерфейса.
. Это значение должно быть строго НОЛЬ. Ненулевое значение указывает на аппаратный сбой контроллера.
• HS link CRC errors: Количество ошибок в высокоскоростных линиях внутренней связи между ASIC’ами внутри роутера.
• MTU errors: Количество пакетов, чей размер привысил MTU на интерфейсе.
• Resource errors: Суммарное количество дропнутых пакетов.
