Habr<p>Кто сообщает картам, где едет ваш транспорт</p><p>Приветствую всех! Когда-то давно здесь уже был пост про то, как работает отображение движения транспорта на Яндекс-Картах. С тех пор мне не раз предлагали рассказать про то, что происходит на «транспортной» стороне: что вообще за устройства установлены на подвижном составе, в каком формате они передают положение и что с этими данными делают дальше. Самое время восполнить это упущение. Итак, в сегодняшней статье поговорим про то, что за девайсы используются на транспорте, позволяя нам знать, когда приедет наш маршрут. Заодно попробуем их запустить, посмотрим на них в работе и узнаем, как работают информаторы в новых автобусах и трамваях.</p><p><a href="https://habr.com/ru/companies/timeweb/articles/889116/" rel="nofollow noopener" translate="no" target="_blank"><span class="invisible">https://</span><span class="ellipsis">habr.com/ru/companies/timeweb/</span><span class="invisible">articles/889116/</span></a></p><p><a href="https://zhub.link/tags/timeweb_%D1%81%D1%82%D0%B0%D1%82%D1%8C%D0%B8" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>timeweb_статьи</span></a> <a href="https://zhub.link/tags/%D1%82%D1%80%D0%B0%D0%BC%D0%B2%D0%B0%D0%B9" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>трамвай</span></a> <a href="https://zhub.link/tags/%D1%82%D1%80%D0%BE%D0%BB%D0%BB%D0%B5%D0%B9%D0%B1%D1%83%D1%81" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>троллейбус</span></a> <a href="https://zhub.link/tags/%D0%B0%D0%B2%D1%82%D0%BE%D0%B1%D1%83%D1%81" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>автобус</span></a> <a href="https://zhub.link/tags/%D0%B3%D0%BE%D1%80%D0%BE%D0%B4%D1%81%D0%BA%D0%BE%D0%B9_%D1%82%D1%80%D0%B0%D0%BD%D1%81%D0%BF%D0%BE%D1%80%D1%82" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>городской_транспорт</span></a> <a href="https://zhub.link/tags/%D0%B8%D0%BD%D1%84%D0%BE%D1%80%D0%BC%D0%B0%D1%82%D0%BE%D1%80" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>информатор</span></a> <a href="https://zhub.link/tags/%D0%B0%D0%B2%D1%82%D0%BE%D0%B8%D0%BD%D1%84%D0%BE%D1%80%D0%BC%D0%B0%D1%82%D0%BE%D1%80" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>автоинформатор</span></a> <a href="https://zhub.link/tags/%D1%81%D0%B5%D0%BB%D0%B5%D0%BD%D0%B0" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>селена</span></a> <a href="https://zhub.link/tags/%D0%BE%D1%80%D0%B1%D0%B8%D1%82%D0%B0" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>орбита</span></a> <a href="https://zhub.link/tags/%D0%B3%D1%80%D0%B0%D0%BD%D0%B8%D1%82" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>гранит</span></a> <a href="https://zhub.link/tags/rs485" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rs485</span></a> <a href="https://zhub.link/tags/rs232" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rs232</span></a> <a href="https://zhub.link/tags/fat32" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>fat32</span></a> <a href="https://zhub.link/tags/microsd" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>microsd</span></a> <a href="https://zhub.link/tags/%D0%B4%D0%B0%D1%82%D1%87%D0%B8%D0%BA_%D1%83%D1%80%D0%BE%D0%B2%D0%BD%D1%8F_%D1%82%D0%BE%D0%BF%D0%BB%D0%B8%D0%B2%D0%B0" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>датчик_уровня_топлива</span></a></p>

Saustrup<p>So, I made a thing. A trivial and somewhat boring thing, but something that brought back memories from the olden days of <a href="https://mstdn.dk/tags/vintagecomputing" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>vintagecomputing</span></a>: a <a href="https://mstdn.dk/tags/RS232" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RS232</span></a> serial loopback adapter! Excellent for testing your favorite <a href="https://mstdn.dk/tags/terminal" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>terminal</span></a>, computer or USB <a href="https://mstdn.dk/tags/serial" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>serial</span></a> adapter. Not 25 pin D-SUB? No worries! I have plenty adapters for that! 🙂 </p><p>I've got more serial goodness in store, but I need to grab a few things from the store first.</p>
TOV<p>A VGA cable uses a 15-pin HD connector, while RS-232 typically uses a 9-pin DB-9 connector.</p><p><a href="https://fosstodon.org/tags/vga" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>vga</span></a> <a href="https://fosstodon.org/tags/rs232" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rs232</span></a> <a href="https://fosstodon.org/tags/cable" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cable</span></a></p>
TOV<p>An RS-232 Serial cable is designed for serial communication between various devices.</p><p>Not to be confused with a VGA cable, which is focused on transmitting video signals for display purposes. They serve different functions, utilize different signal types, and have distinct physical connectors.</p><p><a href="https://fosstodon.org/tags/serial" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>serial</span></a> <a href="https://fosstodon.org/tags/cable" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>cable</span></a> <a href="https://fosstodon.org/tags/rs232" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>rs232</span></a></p>

John Carlsen 🇺🇸🇳🇱🇪🇺<p>For the first time in probably 28 years, I powered up my old Data I/O Model 60A Logic Programmer.</p><p>I plugged it in to the <a href="https://sfba.social/tags/RS232" class="mention hashtag" rel="nofollow noopener" target="_blank">#<span>RS232</span></a> serial port of my Panasonic Toughbook CF-31 laptop computer running Linux Mint Debian Edition 6 (LMDE6) terminal window and found and ran cu ("call up") to reach the serial port to display the machine's menu and its system configuration. (I used stty to check the port settings, but didn't even need to change any.)</p><p>I'm surprised that it worked as well (and as easily) as it did.</p><p>They really built those things.</p>
Daniele Verducci 🧉I found the connection I made was not working. I connected the <a class="hashtag" href="https://social.ichibi.eu/tag/esp8266" rel="nofollow noopener" target="_blank">#esp8266</a> tx pin to the <a class="hashtag" href="https://social.ichibi.eu/tag/uart" rel="nofollow noopener" target="_blank">#uart</a> to <a class="hashtag" href="https://social.ichibi.eu/tag/rs232" rel="nofollow noopener" target="_blank">#rs232</a> converter's rx pin and vice versa.<br>So tried inverting it (rx to rx and tx to tx) and now it works perfectly... Not sure why the pins are labeled reverse on the uart to rs232 converter... 🤷‍♂️
Daniele Verducci 🧉At the end, all will fit in this enclosure (there was an adsl filter inside). I made some holes for the usb and the reset button. The front hole contained two rj11 sockets, I cut the central divisor and obtained a hole the perfect size for the <a class="hashtag" href="https://social.ichibi.eu/tag/uart" rel="nofollow noopener" target="_blank">#uart</a> to <a class="hashtag" href="https://social.ichibi.eu/tag/rs232" rel="nofollow noopener" target="_blank">#rs232</a> <a class="hashtag" href="https://social.ichibi.eu/tag/db9" rel="nofollow noopener" target="_blank">#db9</a> connector.<br>Most of my <a class="hashtag" href="https://social.ichibi.eu/tag/retrocomputing" rel="nofollow noopener" target="_blank">#retrocomputing</a> gear has the old <a class="hashtag" href="https://social.ichibi.eu/tag/db25" rel="nofollow noopener" target="_blank">#db25</a> connector, so I'll need an adapter anyway...<br><br><a class="hashtag" href="https://social.ichibi.eu/tag/zimodem" rel="nofollow noopener" target="_blank">#zimodem</a> <a class="hashtag" href="https://social.ichibi.eu/tag/wifi" rel="nofollow noopener" target="_blank">#wifi</a> <a class="hashtag" href="https://social.ichibi.eu/tag/modem" rel="nofollow noopener" target="_blank">#modem</a> <a class="hashtag" href="https://social.ichibi.eu/tag/hayes" rel="nofollow noopener" target="_blank">#hayes</a>
Daniele Verducci 🧉Every time I do some project "for fun" (= not for work) I try to learn something new, in that way i can say the time needed is not wasted.<br>So, this time I decided to try <a class="hashtag" href="https://social.ichibi.eu/tag/wirewrapping" rel="nofollow noopener" target="_blank">#wirewrapping</a> . This is a very simple circuit, with no board, so it's a very very simple case, but I tried and I liked it!<br><br>Here a photo while connecting the <a class="hashtag" href="https://social.ichibi.eu/tag/esp8266" rel="nofollow noopener" target="_blank">#esp8266</a> (already flashed with <a class="hashtag" href="https://social.ichibi.eu/tag/zimodem" rel="nofollow noopener" target="_blank">#zimodem</a> and configured to connect to my wifi) with the <a class="hashtag" href="https://social.ichibi.eu/tag/uart" rel="nofollow noopener" target="_blank">#UART</a> to <a class="hashtag" href="https://social.ichibi.eu/tag/rs232" rel="nofollow noopener" target="_blank">#RS232</a> adapter.
