What are the tradeoffs of using RS-232 vs. GPIB in my test
Question : What are the tradeoffs of using RS-232 vs. GPIB in my test and measurement system? Answer : The RS-232 interface bus is the slowest, since data is transferred in a serial fashion, one bit at a time over a single line. RS-232 interfacing is, on the other hand, inexpensive.

Difference between 'GPIB to USB' and 'RS232 to USB' adaptors
May 4, 2021 · GPIB allows very easy connection of upto 15 devices on the same GPIB port, which is rather "uncommon" for RS232. Back in the days the transfer speed on GPIB was better than on RS232, but nowadays with 2MBaud RS232 connections this might be nearly on par…
How to Choose the Right Hardware Bus for Your Instrument …
Nov 9, 2023 · These include test and measurement-specific buses such as GPIB and PC-standard buses such as serial (RS232), Ethernet, and USB. You can use some stand-alone buses as a medium for other stand-alone buses, such as a USB-to-GPIB converter.

Which Mode Should I Use During The GPIB-RS232 Communication?
Jan 24, 2020 · Data a GPIB controller sends while a serial device is addressed is sent over the serial interface. C mode: When the GPIB-RS232/485/422 is configured for C Mode, it acts as a passthrough device that reads serial data and transfers it over GPIB.
GPIB-RS232 - NI - National Instruments
The GPIB‑RS232 is an IEEE 488 controller device for computers with an RS232 port. You can use this device to integrate an instrument into your system using GPIB. This device transforms a computer with an RS232 serial port into a talker, listener, or controller on the GPIB bus.
