An infrared transmit and receive interface has been converted to an RS232 serial interface on this project with the use of a microchip PIC microcontroller. A sequence of bits modulated as a series of ...

[Shane] bought a multimeter with the idea of using its serial output as a source for data logging. A multimeter with a serial port is a blessing, but it’s still RS-232 with bipolar voltage levels.

The converter is designed for half duplex mode where the PC communicates with ROV using 2 wires from RS232 and RS485 interface. The converter is designed for half duplex mode where the PC communicates ...

Powered from as little as 3V, the ST3243E RS-232 transceiver and ST3232E multiple RS-232 driver/receiver chips are rated at a minimum transfer rate of 250 Kb/s and are said to provide rugged ESD ...

i'm trying to buy a USB to RS-232 adapter for use with my M1 Mac Mini, but this is turning out to be a lot more complicated than i thought it would be. the most common devices seem to be based on ...

I know, RS-232 is not gone completely but in most things it has disappeared. Recently I bought a new laptop to use in my ham shack. I have several older accessories that use RS-232 and I had hoped to ...
