A PC’s serial port provides signal lines that you can use to read voltage levels of digital circuits. You can use the port to test digital TTL (transistor-to-transistor-logic)-level circuits. You just ...

The project illustrates aims to produce a multiplexer that would allow the connection of 4 devices to a single RS232 port. The one single port can be used to control even an arbitrary number of ...

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 ...

What is RS-232? Why was RS-232 important? Take our poll and see what others think of RS-232. RS-232 (Recommended Standard 232) was introduced in 1960 for serial communication transmission of data.

With Linux and the serial port there is good news and there is bad news. The good news is that Linux has great support for serial hardware of all sorts and a host of tools for accessing the serial ...

The device shown in Figure 17-1 is an RS-232–to–TTL converter board, designed to allow a PC with a serial (RS-232) port to communicate with a device that has a console (TTL) port. External converters ...

Designed for use in multidrop RS-232 applications, the MAX3322E and MAX3323E transceivers feature a switchable input impedance, with the impedance capable of being an RS-232, 5-k? load or a ...

Q: What is the function of an RS-232 port? A: An RS-232 port is a standard digital physical interface and protocol for relatively low-speed serial data communication between computers and related ...

When did you last buy a mouse? Did it have a little adapter in the box? There was a time when if you bought a USB mouse, in the box was also an adapter to allow it to be used with the older PS/2 ...

Wedge barcode scanners and serial barcode scanners both connect to a PC to scan barcodes into the system. They do not, however, work the same way and each has advantages and disadvantages. This ...
