You will need one of these that will accept an operating voltage of 5 volts. We can install it using the following This serial port allows the microcontroller to communicate with devices such as other computers, printers, input sensors, and LCDs.
One key difference is that the signals are LVTTL (0 – 3. This cable provides a virtual serial port interface to the PC host and the normal serial signals at the target.Stratus Engineering's EZ-Tap Pro hardware module RS232 sniffer is a sophisticated protocol analyzer and bus analyzer hardware solution that overcomes latency and time-tagging problems associated with traditional dual COM port monitoring solutions. The first test plug can be used to check the function of the RS232 serial port with standard terminal software.
