Me pareció interesante la idea de interconectar Arduinos y así formar redes, para ello tenemos diferentes formas de hacerlo: RS232, I2C, RS485 y BusCAN. Iré investigando estos 4 protocolos en el orden citado arriba. En esta ocasión toca ver el RS232 que también sirve para conectar nuestro ***duino al ordenador. Para comunicar RS232 y Arduino que utiliza TTL necesitaremos convertir la señal, se lo puede hacer a través de un sistema simple con transistores y resistencias pero también se pu.......

Hi All, I have a pool controller that I would like to control. Research thus far (based on chips on the pcb etc) has led me to believe its running a serial interface, possibly RS485. However, as its designed for long runs its using 33VDC with respect to GND. I realise I could direct connect to the main CPU, but its a pain to work in or around the pool equipment enclosure. And if I do eventually make my own interface it will need to be able to send/receive at 33V. So, my long question is:Is there.......

Author: Chaonan Chen, Huihui Duan, Au Group ElectronicsThe RS485 Convertor (Part # CVT485 and CVT485E)is a handheld device typically used for converting RS485/SAE J1708 signal (two-wire operation balanced half-duplex) to a RS232 signal (two-channel) and vice verse. An external +12V power supply is required.It has a DB-9 female RS-232C connector and a DB-9 male/female connector on the RS485 bus side. The DB-9 male-connector and its cable on the RS485 side is the most popular choice. Major Feature.......
