FAQ

Q: Can RS232 be full duplex?

A: RS-232 operates in a full duplex mode, meaning the controller and receiver can communicate at the same time without interference. Mensor transducers with RS-232 require three wires for set up: Transmit Data (TX), Receive Data (RX), and Signal Ground.

Q: What is the difference between RS232 422 and 485?

A: RS232 is full-duplex, RS485 is half-duplex, and RS422 is full-duplex. RS485 and RS232 are the only physical communication protocols (i.e., interface standard); RS485 is the differential transmission mode, and RS232 is the single-ended transmission mode.

Q: Do I need a driver for RS232 to USB adapter?

A: To handle the packets and move data in and out of the program accessing the USB device, a software driver is needed. The software driver sits between the hardware and the computer program you are using, and it must be installed and working correctly.

Q: Is RS-232 outdated?

A: Two of the oldest interfaces are RS-232 and RS-485. Surprisingly, these legacy interfaces aren't obsolete. Both are still used in a variety of applications.

Q: Is RS-485 full-duplex or half-duplex?

A: RS-485 is a duplex communication system in which multiple devices on the same bus can communicate in both directions. RS-485 is most often used as half-duplex, as shown in the figures above, with only a single communication line.
