1-12-2002 | Many Metex DVMs feature a serial interface (RS232) which enables measured values to be copied to a PC for processing. Although this works ju...

1-05-2002 | This project has been designed to interface an EIA-232 channel to an EIA-485 half-duplex bus. We should do so because EIA-485 offers more fe...

1-12-2001 | The circuit converts an analogue voltage to its digital equivalent which is transmitted to a PC via an RS232 link.This type of circuit is us...

1-12-2001 | Only simple materials and a little bit of skill are needed to build an RS232 switch. All that you need are two 9-way sub-D plugs with solder...

1-10-2001 | With the help of a minimal quantity of hardware and a simple piece of software it is possible to tap into the data stream between two serial...

1-07-2001 | This circuit represents an interface converter between the UART pins of a microcontroller (with TTL levels) and a ‘standardised’ RS232 port...

1-07-2001 | Back in October 2000 we described a versatile I2C bus interface that plugged into the PC printer port. Nowadays the PC serial port is rarely...

1-06-2001 | This project is a card with 32 analogue inputs with 12-bit resolution each for external connection to the serial port. The feature par excel...

1-04-2001 | Early 1995, Yamaha introduced a new range of synthesizers with interesting interface capabilities. For the first time, these machines were c...

1-01-2001 | Going through our archives we discovered that it’s been almost ten years since we published an EPROM emulator. The version we propose in thi...
