RS232 converter <-> RS485 is used to change the voltage levels, complying with these standards. The characteristics of the voltage converter to RS232 levels in transformed, corresponding standard TTL, and then converted into levels, adopted RS485. Converter further has an automatic switch between sending and receiving.… Continue Reading
The device is an easy to use module., which allows you to use a Bluetooth connection in any system with a UART interface. The device is designed and built on the basis of the BTM-222 transmission module. It provides a range of up to 100 m (depending on distribution conditions). Undeniable… Continue Reading
Simple and inexpensive thermometer for PC, which allows you to measure and record the temperature of 8 and temperature sensors. An apparatus adapted for data transmission over the Internet. Communication with the computer via an RS232 serial connector. The DS1820 that communicate used as temperature sensors… Continue Reading
Rejection of "modem" signal, from time to time used in modern devices, reduced the number of circuit terminals and use tiny QFN16 housing and SSOP16. This reduces the space, occupied by the USB interface system, minimuma.Opisanny to the required project is a miniature… Continue Reading
This article presents the design of the converter, to connect your device with an RS232 interface to the PC. Due to the galvanic isolation, the conversion will be especially useful for people, that trigger industrial device avtomatizatsii.Raznitsa potentials between these two devices is often caused damage to the electronic components. Most… Continue Reading
