Many devices in the industrial environments are still using an RS-232 serial communication link. RS-232 uses two signal levels to distinguish between a logical "1" and a logical "0". A logical "1" is represented by -12 V and a logical "0" is represented by +12 V. RS-232 can operate on different bit rates, standard values lie between 110 bit/s and 115200 bit/s. To synchronize the sending and receiving devices, start and/or stop bits can be added to the data to transfer. RS-232 supports a simple validity check of the transmitted data, using a parity bit that can be added to the data. Two signal lines are available, TxD (Transmit Data) and RxD (Receive Data). These can be used simultaneously, which makes full-duplex communications possible.

In this example, a Handyscope HS5 is used to measure serial communication from a computer running a terminal program, in which text is typed.

Now everything is properly setup, type a word in the terminal program to create a serial communication. The instrument will capture this communication and the serial decoder will analyze and decode it.

To analyze the RS-232 signals, the UART / serial decoder I/O is used. Create one by clicking IOs in the object tree, selecting Decode and then UART / Serial decoder.

In our example, the word "tiepie" was typed and measured and converted by the serial decoder. The decoded information is shown in the table.

In industrial environments, the measured signals can be very "dirty", causing the Serial decoder to have problems decoding the communication properly. Cleaning the signals may improve the ability of the Serial decoder to decode the signals properly.

AMOLED (Active-Matrix Organic Light-Emitting Diode) screens are based on a series of emitting organic materials. Each pixel is an emitting diode that can illuminate itself without a backlight source. This makes AMOLED screens more power-efficient, with deeper blacks and more vibrant colors.

The WiFiScope WS6 DIFF, WiFiScope WS6, WiFiScope WS5, WiFiScope WS4 DIFF, Handyscope HS6 DIFF, Handyscope HS5, Handyscope HS4 DIFF, Handyscope HS4 and the Handyscope HS3 are suitable instruments to measure RS-232 signals.

The biggest differences between AMOLED, TFT, and IPS screens lie in their display technology and physical structure. Specifically, their differences lie in how they produce color and contrast, as well as how they perform in different scenarios.

To display the decoded UART / serial messages, a Table sink is used. Create one by clicking Sinks in the object tree and then Table. Connect the UART / serial decoder to the table sink by dragging it on the table sink in the object tree.

AMOLED, TFT, and IPS screens are different types of liquid crystal display technologies. They all consist of a liquid crystal layer, a backlight source, and a color filter. However, their basic principles are different.

In our example, a 110 bit/s serial communication is used. Therefore, set the time base to a sampling frequency that is ten times higher, 1 kHz. Since we will be typing text in a terminal program, we need sufficient measuring time, e.g. 2 seconds. With a sampling frequency of 1 kHz, that requires 2000 samples record length.

Each pixel in an AMOLED screen is a self-illuminating diode. This means that AMOLED screens can produce very vibrant, saturated colors, with deeper blacks and higher contrast. In contrast, IPS screens can produce more accurate and natural colors, but they may not be as vibrant or have as deep blacks. TFT screens' color performance lies between AMOLED and IPS screens, typically more vibrant than IPS screens but slightly less so than AMOLED screens.

We are using Ch1 to measure the Transmitted Data (TxD). To simplify recognition of the signal, it can be given a descriptive name (alias). To change the alias of a channel, right-click the channel in the object tree and select Alias... and enter the required alias. Give Ch1 the alias "TxD".

IPS screens are best suited for scenarios such as: editing photos and videos - IPS screens can provide more accurate and natural colors, making them suitable for editing photos and videos. Office environments - IPS screens' wide viewing angles and accurate colors can provide a better visual experience, making them more suitable for office environments.

TFT screens are suitable for scenarios such as: gaming and high-speed video scenes - TFT screens have a fast response time and can provide smoother images, making them more suitable for gaming and high-speed video scenes. Commercial applications - If you need a large screen to display static information or text, TFT screens can be a good choice.

AMOLED screens are best suited for scenarios such as: watching movies and playing games - AMOLED screens can provide more vibrant, true-to-life colors and deeper blacks, making them ideal for watching movies and playing games. Viewing images - If you have a demand for color accuracy and saturation, AMOLED screens are also a good choice.

IPS (In-Plane Switching) screens are also a type of liquid crystal display technology, where each pixel is controlled by a liquid crystal molecule. These molecules can rotate to control the degree of light passing through, displaying the image. IPS screens typically offer better color.

Each pixel in an AMOLED screen can illuminate itself, so black pixels can be turned off to save energy. In contrast, IPS and TFT screens require a backlight, so they still consume power when displaying black. Therefore, they have higher power consumption.

RS-232 signals lie between -12 V and +12 V, idle state = -12 V. Therefore, set the channel input coupling of the channel to "DC" and set the input sensitivity of the channel to "20 V" full scale. That way both signal levels can be measured properly.

Now connect Ch1 to the TxD line of the COM port of the computer. Connect the ground terminal of the input to CG (chassis ground) of the COM port.

The UART / Serial decoder can show more information in columns in the tabel that are not by default enabled. Click the Column select button to enable or disable columns in the table.

Open your favorite terminal program (e.g. Hyperterminal) and set it up to communicate through a serial (COM) port using the following settings:

TFT screens have a shorter response time and are typically suitable for gaming and high-speed video scenarios, while IPS and AMOLED screens have slower response times and may experience motion blur and other issues.

The TiePie engineering Multi Channel oscilloscope software is capable of analyzing RS232 signals, using the UART / Serial decoder.

To measure single RS-232 signals, a measuring instrument with at least one channel is required. To measure full-duplex signals, an instrument with at least two channels is required. The maximum frequency on the RS-232 bus depends on the bit rate that is used. The instrument must sample at at least three times the bit rate on the bus, but preferable ten times higher, on each channel. For a 110 bit/s bus that would mean a minimum sampling frequency of at least 1 kHz on both channels. RS-232 uses voltages between -12 and +12 V, so the instrument should be able to measure voltages between -12 and +12 V. Since data transfers can be long, a long record length is preferred to capture the communication.

To examine the transferred data in the measured signals, the various pulses have to be examined, the start and stop bits have to be taken out and the parity bit too, when used. The remaining bits have to be converted into readable data.

When a block of communication is longer than the table, it is not possible to see all text that is appended. The table has an auto scroll function, which always makes sure the bottom lines are visible. To toggle this function, click the Auto scroll button.

In idle state, the TxD line has a logic "1", which means that the voltage on the line = -12 V. When communication starts, first a start bit, a logic "0" (+12 V) is transmitted. That means that the start of a communication sequence is a rising edge. Therefore, set the trigger type to rising edge. The trigger level and trigger hysteresis are not really important, as long as they are within the -12 to +12 V range. Set the trigger level to e.g. 50% and the hysteresis to e.g. 2.5%. To make sure that the measurement is only started when the communication begins, the trigger timeout has to be set to infinite.
