Possibly related but probably not. Traditional COM port monitoring solutions often leave developers experiencing latency and time-lagging issues that make their monitoring tasks more difficult.
A quality serial monitor can help eliminate these issues by presenting the monitoring information in a user-friendly manner and allowing the user to save monitoring data to a file. Time-stamping of data transmission and handshaking events make it easy to analyze your monitoring results at your convenience. COM monitors typically require no programming skills to be used effectively. Installation is usually straightforward and can be done by anyone with basic computer skills.
Once the tool is installed all of your serial port traffic will be monitored and can be analyzed by the proper personnel at any time. RS monitors are useful to businesses in almost any industry. One of the driving forces of any business is to gain a competitive edge in its area of expertise. One way to gain an advantage over your competitors is by saving time and money in your daily operations. Using RS port monitor utility can save time for your developers and money by eliminating the need for any additional hardware when working with your serial devices and applications.
Companies in industries as diverse as communications, semiconductor manufacturing, design services, and industrial instrumentation all have taken advantage of RS monitoring software. Companies of any size can benefit from this software, and its use can help smaller companies compete with their larger competitors.

Olga Weis Jul 27, Advanced RS monitor software by Electronic Team. Serial Port Monitor. Download day fully-functional trial period. Some highlights are: The ability to open and monitor a port already opened by another application. Four different data views. See your data in table, line, dump or terminal mode. You can also see all modes at the same time in the display window Flexible and user-friendly interface that allows easy access to your serial ports without the need for any programming skills.
Playback and session comparison lets you repeat the exact commands or data sent to a device and automatically displays the differences between sessions. Monitor multiple ports within one monitoring session. Send monitored data to files or the clipboard for easy analysis. Fully supports all Windows versions including Windows Free Serial Port Monitor Free Serial Port Monitor is a RS protocol analyzer that provides you with a simple and effective way to sniff the incoming data from both virtual and real serial ports.
No unnecessary costs: This software is totally free! Free Serial Protocol Analyzer by HDD Software Here is another free software tool that is designed to run on older versions of Windows and will allow you to display and analyze data exchanged between an application and a serial device.
Portmon for Windows Portmon for Windows lets you monitor and display both serial and parallel port activity on legacy versions of the Windows OS. A serial port was standard on personal computers until the late s, when it was mostly replaced by the Universal Serial Bus USB.
It is still common on legacy devices that use serial communications for data capture, configuration and control. What is the difference between RS and RS? It specified the same DB25 connector as the original RS standard. RS is also found on professional video broadcasting equipment. The RS standard was published in and is substantially similar to the earlier RS standard.
The big difference is support for multiple transmitters and receivers, allowing devices connected on an RS network to "talk amongst themselves" in half-duplex mode over inexpensive twisted pair cabling.
RS describes the electrical characteristics of the drivers and receivers but does not specify a communication protocol. RS has been widely used as the physical layer for standard and proprietary protocols in industrial control systems, including Modbus and Allen Bradley DH Point-to-Point — a connection between two devices in which bits are transmitted sequentially, one at a time.
Multidrop — a type of bus in which multiple devices are connected at the same time. Through a process of arbitration, one device sends and other devices listen for data packets intended for them. Unbalanced vs. Balanced — A balanced transmission requires three wires, two signal wires and a ground. Both signal wires carry the same signal, with one signal the inverse of the other this is referred to as Differential Signaling.
In an unbalanced transmission, the signal is carried on one conductor and a second conductor is used for ground. The D-Subminiature or D-Sub connector is named for the D-shaped metal shield that protects the pins and ensures the correct orientation. First introduced by Cannon in , the D-sub form factor was adopted for the RS serial communications standard.
The pin D-Sub was the only connector specified in the original RS standard. The 25 pins handled the data transmission, control signaling and grounding required by the relatively simple applications and devices of the time. Many serial devices did not implement all 20 control signals in the original RS specification. Smaller, simplified connectors with fewer pins, like the DB9, quickly emerged.
It was also used as a serial connector for game controllers e. The RS standard defines voltage levels for logical 1 and logical 0. Devices, such as computers and printers, use control signals to synchronize the transmitting and receiving of data. These signals indicate the status of Sender and Receiver ready, busy, transmitting and receiving and control the flow of data. For example, the signals supported by a DB9 connector are:. A standard serial port transmits at Kbps. This may be faster than the connected device can handle.
Using flow control RTS and CTS , the device can temporarily stop the flow of data from the computer so it can process the data in its buffer. RS cables can be simple parallel wires or twisted pair up to 15 m 50 ft. For all serial communication, there is an inverse relationship between cable length and data transmission speed.
At the maximum length of 15 meters 50 feet , an RS port will support a data rates up to 20 Kbps. Greater distances can be achieved with a slower data rate and shielded CATx cable see RJ45 serial adapters. Computer peripherals such as printers have also adopted the USB interface or gone wireless. However, some network switches, routers and serial devices still use a serial interface, including lab equipment, barcode readers, industrial controllers and data gathering sensors.
When a host computer boots up, it assigns a port address to each device including any USB adapters connected to the bus and determines the type of data transfer the device wants to perform. Once the adapter is registered, it looks like a USB peripheral device to the host computer. If you do not see this heading, go to the View menu and make sure Show Hidden Devices is selected. If you still do not see your adapter, you will need to install the manufacturer's driver for your device.
The chipset creates an interface between a legacy serial device and a computer with a USB port, allowing the computer to read and write to the adapter using USB commands and the serial device to send and receive serial signals. Since RS devices signal using higher voltages, the adapter also needs a "level shifter" to boost the signal voltage up to the level expected by the RS receiver and a transient suppressor to protect the USB circuitry from damage.
What is the difference between a serial cable and a parallel cable? Serial cables transmit one bit at a time across a single wire. Each bit in a packet of data is sent sequentially with a start and stop bit at the beginning and end of each packet.
Parallel cables transmit all bits in a packet at the same time, one per wire. For an 8-bit byte, the parallel cable would need 8 wires. The receiving device reassembles the packet so the bits appear in the correct order.
