Windows How to Read Virtual Com Port Share

Serial data splitter software works by taking a unmarried serial port, say COM1, and sharing information technology into several virtual ports (COM2, COM3, COM4, etc.). Each of these newly created virtual ports volition announced in your device manager as if they were bodily hardware interfaces and will emulate all of the settings of a physical port. Now, applications can be assigned to the virtual serial ports through a unique identifier, eliminating compatibility bug. You tin now assign COM2, COM3, etc. where previously only i awarding could be assigned to COM1 at a time.

How to share COM ports between applications?

Here are pace-by-footstep instructions on how to share COM port data between several applications using Serial Port Splitter.

1. Launch VSPD Pro on your Windows machine.


2. Open the "Share" tab and select the series port that yous intend to share.


3. Choose the applications that will be sharing access to the port and gear up their custom rights. You volition demand to specify the full path to each application and so click the "Set custom rights" push button to go on.
   
4. Toggle the "Read", "Write", and "Control" option for each application.

   Note: Only one app can control the device, so in most cases "Read/Write" is a sufficient level of access when sharing a device or port.



5. Click on the "Add together share" button to create a bundle that will appear in the bundle tree. The connected applications will now share the port you lot selected at the beginning of this procedure.

VSPD PRO benefits beyond simply splitting serial port

Likewise being an fantabulous software series port splitter, Virtual Serial Port Commuter Pro is packed with other features and capabilities that increase your productivity when working with serial protocols and interfaces. In improver to splitting serial ports, hither are some of the other tasks that can be achieved with this software application:

• Joining COM Ports - VSPD Pro lets you link multiple physical COM ports to one virtual port. A serial application connected to this virtual serial port volition receive data simultaneously from all the joined real COM ports. This allows y'all to redirect information from multiple devices back to one application.

This can be useful for a monitoring awarding that may need to access many serial devices in an industrial automation setting. With a unmarried physical connection, you can monitor every bit many virtual connections as your system can handle.

• Automated Port Switching - If you have an awarding that can only piece of work with a express number of ports the Switcher feature of VSPD Pro is just what you lot need. It allows y'all to combine several physical ports into ane virtual one and create a switcher to the newly created virtual port in your application.

When your program needs a serial interface the switcher detects an open up COM port from the list of joined ports and makes it available to the app. Your program ever gains access to a port as if it was the same physical port.

• Creating Bundle Connections - Complex bundles of serial interfaces can be created and managed with this avant-garde feature of VSPD Pro.

It gives you the ability to transmit series information in and out of an unlimited number of concrete or virtual serial interfaces. Data received at the 'IN' side of the bundle will be sent to every serial interface on the 'OUT' side of the bundle. This transmission mode works in both directions. Y'all can manage the hardware control lines by setting a main port for each side of the parcel. This facility tin can be very helpful when multiple devices or applications need to communicate with the same serial device.

• Merging COM Ports - Using this feature you can add whatsoever number of physical or virtual serial ports to a single series port bundle not divided into 'IN' and 'OUT' sides. All information sent to one port is replicated to all other ports in the parcel. All devices and applications can now modify information with multiple devices and applications at the same time.

Hardware Alternatives to Serial Port Splitter software

Using a great software application similar Serial Port Splitter is not the only way to share a COM port. Serial port splitter hardware is available in a number of varieties that can also let y'all to share series ports, though not with the same flexibility as that offered by the software solution. They are marketed under a number of names. Ii of the most popular options are:

DB9 Splitter Box

A DB9 splitter box is a device that has a single male or female person DB9 connector at ane stop and splits the signal into multiple DB9 connectors of the reverse type at the other end. You might take a single male connector on i end and two female connectors at the other end. This blazon of device allows two computers or applications to be attached to a unmarried serial device.

Serial Cable Splitter

A serial cable splitter is just some other term for a DB9 splitter box. They all work in a similar fashion, offering multiple out connections from a single input.

There are some advantages and disadvantages to using a hardware solution when you demand to split up serial ports. Let's look at the pros and cons of hardware serial splitters.

Pros:

• No software installation is required.
• They tin be used sequentially with multiple machines.

Cons:

• Physical limitations exist regarding cable length.
• Limited by the number of physical connections congenital into the device.
• They introduce additional cables that need to be managed.

Summing up, the software solution for splitting and sharing serial ports offers much more flexibility than a hardware solution. Boosted features such as bundling and COM port merging are not possible past simply using another hardware component. Using a tool like Serial Port Splitter gives you the same capabilities of a hardware solution, plus a host of boosted features that the hardware cannot provide.

Scenarios for successful application of the serial RS232 port splitter

There are many times when being able to split and share COM devices can be the best style to solve a usage problem. Allow'due south take a look at some situations where having the ability to split RS232 or other series interfaces tin be useful.

Ham radio enthusiasts scenario.

Ham radio operators need to be able to command and admission their transceivers. The transceiver is usually attached to a estimator via a standard RS-232 interface. Most ham radio operators will desire to have several applications running at once and they all demand to communicate with the transceiver through a single COM port. That cannot exist washed on the Windows operating arrangement as Windows limits the number of connections to a COM device to a single one.

If you lot are trying to run a station log book too equally station control software y'all are forced to close downwards one application earlier opening the other one. This is not an efficient way of operating although it is a mutual method that ham operators must resort to in order to pursue their hobby. A meliorate culling would exist to install and utilize Serial Port Splitter to share RS-232 signals from a single COM device to multiple virtual interfaces. This enables each software application needed to operate the radio to have their own, simultaneous connection to the transceiver.

Sailing navigation

Computer controlled navigation is possible using an application that connects to a GPS device. The GPS is frequently attached to the computer past way of a serial connection. Accurate planning of the route can be done with a single connection to the GPS, but what if you lot want to log your route as well? You are faced with the prospect of purchasing some other GPS unit of measurement to attach to your logging application.

Hither once more, employing a series splitter software application can save y'all the expense of purchasing another device as well as keep your working area uncluttered. Install the software and you can share your GPS unit with as many applications as yous wish.

As yous tin see, having the ability to split a serial port can be very useful in a number of situations. Using serial splitter software enables you to save money and increment your productivity without the addition of a single slice of hardware.

Collecting weather station data

Many hobbyists maintain personal weather stations on their property that they rely on for immediate and accurate temperature, humidity, and wind measurements. In some cases, they will post this information to a personal website and may as well want to submit that data to public weather sites.

Unfortunately, the chances are depression that the information can be shared directly between the personal weather plan and the public site. More probable is that the data formats will be different, necessitating two connections to the raw data generated by the weather station. Splitting the serial port that is continued to the weather station is the easiest way to become the data to both programs so they tin can manipulate it as needed. A virtual COM port splitter is a perfect software solution for this scenario.
