(5) The RS-232-C interface allows only one transceiver to be connected to the bus, ie single-station capability; while the RS-485 interface allows only up to 128 transceivers to be connected on the bus, ie multi
I am very new to Matlab. I used Teraterm to communicate with the device (Transmission and protection system SEL-311C). I can send commands and receive the responses in Teraterm but while I try to use Matlab, I cannot get anythin...

interface will remain one of the most popular ways to connect peripheral devices to a computer. Newer devices that are designed to use USB ports to connect to a computer have drives that allow the emulation of serial ports, enabling them to communicate with software employing the RS232 protocol...
When one network wants to communicate with another, the data packet is passed to the network gateway prior to being routed to the destination through the most optimal path. A network gateway can be compared to an express station. When sending a parcel, you only need to provide the express ...

Solution 1: Use a JTAG debugger or a UART/RS232 cable and inspect the return status of all calls to see if any of them failed. Then, use the API Guide to understand why the call failed. • Cause 2: The USB signal integrity in the board...
I am trying to implement RS232 reading via an USB adapter on a RevPi (Raspberry). It worked perfectly fine until now. I was able to read the port but now it is not doing anything but giving all kinds of error codes (which are documented here: https://help.codesys.com/webapp/Errors;...
Hello !I have selected the RF310R for this project to read RFID tags. I have purchased the RF340T tags and plan to communicate with the RF310R using a PC via an RS232 to RS422 converter. However, there is very little information available here about cont
