???<BR><BR>I have a propriatery RS232 device that I need to connect to a computer that has no serial ports (newer laptop). The hardware has a dongle incorporated into the cable to unlock the software ...

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 ...

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 ...

In the early 80s, millions of terminals were handed out to French telephone subscribers. Nearly 9 million of these Minitel dumb terminals were in use at one time, and with that degree of ubiquity, ...

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 ...

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 ...
