With no change to associated computer hardware or software, the device, called ADAM-4520A, transparently converts RS-232 signals to RS-422 or RS-485. It “allows users to take advantage of RS-422 and ...

Thus, selecting RS-232 or RS-485 mode is easily accomplished. The switch operates from a single supply of +12 V dc, and digital-input thresholds ensure TTL-compatibility for the connected devices.

[André Sarmento] needed to connect a computer to an RS-485 bus. A simple converter can be sourced online, but the only thing he could find locally that was even close was a USB to RS-232 converter.

Sfera Labs has released its new Quad RS-422/RS-485 X2-Series Expansion Board for the Strato Pi Max platform. Designed to fulfil the most demanding communication needs, this expansion board delivers ...

The popular RS-485 and RS-422 serial data networks used in industrial automation can now be made better than ever thanks to Exar’s SP349x series of transceivers, which offer data ...

These low-power devices serve as drop-in upgrades to existing RS-485 designs without costly board redesigns. ... LVDS, CAN, I2C, ESD, RS-485, RS-232 and PCI-Express standards. semicon.

I'm a bit out of my league on this one. I need to take realtime data from a serial source and display it in a "retail display" type of fashion. My PLC sends data out via RS232 (I also have RF485 ...

These RS-232 outputs travel to the input lines (Pin 2) of the two monitoring computers. When one of the computers transmits on Pin 3 of its serial port, its output converts to TTL levels with IC 4.

I’ve taken to using CAN transceivers instead of RS-485 transceivers; no stress on the parts when two devices transmit at the same time. (An yes, this is one async serial ports.) ...

This white paper will discuss serial communication and legacy with RS-485. RS-485 is typically easily understood and applied, even by personnel with limited experience in networking and communications ...
