An appropriate serial cable consisting of female/male DB9 connectors is connected to this port. Figure 2 shows a picture of a standard PC DB9 type serial port. The serial port is generally either a DB9 connector or DB25 connector. Serial data is accessed from the serial port on a standard PC. The experiment set up is shown in Figure 1. Terminal program such as Hyperterminal for Win95/98, Terminal for Win3.1 or Telix for Linux.Īlways keep in mind that the ground of the 2205 is common to the ground of the PC and thus common to AC ground.PicoScope 2205 oscilloscope, scope probe.Electronics experimenter such as an amateur radio operator.First introductory data communications course for college/university.Monitoring this data using the PicoScope 2205A PC oscilloscope.Using a modern digital instrument such as the PicoScope 2205A makes capture and viewing of serial data easy. Unlike analog waveforms such as sine waves and square waves that are periodic in nature, serial data comm waveforms are generally aperiodic. Serial data communications represents the fundamental method by which information is transported in our modern world.Ĭonvergence between communications and computers has caused all forms of information to be digitized for easy transport in serial format. This experiment demonstrates how a serial data communication protocol can be successfully monitored. For example, to calculate the power from a boiler the output temperature could be subtracted from the input temperature and multiplied by the flow.Experiment to look at serial data communications Introduction Equation scaling allows mathematical operations to be carried out. Linear scaling can be done with the slope and offset functions, non linear sensors (such as thermistors) can be calibrated using a lookup table. Advanced scaling functions can convert inputs from a wide range of sensors into sensible units. PicoLog for DOS does not support products released since 1998 (eg DrDAQ, 12 bit ADC-11, ADC-200, ADC-212, ADC-216, PT-104, PicoScope 3000, etc)Įach recorded sample can be the minimum, maximum or average of a number of readings taken over a period from a millisecond to a day. PicoLog for Windows is far more advanced. ***PicoLog for DOS is no longer updated.*** PicoLog is a powerful but flexible data logging package for collecting, analysing and displaying data from the Pico ADC range.
