Rs232 splitter box

Types of RS232 Splitter Boxes

An RS232 splitter box is mainly used to take one input signal and split it into multiple outputs. It enables users to connect one RS-232 device to multiple other devices or computers. These splitter boxes come in various types designed to cater to different needs.

The first common type is the Dual port splitter. Dual port splitters have one input port and two output ports. Organizations or companies whose work involves testing cables often use them. They allow users to take one output signal and split it into two, thus enabling two devices to receive the same signal.

The other common type is the four-port splitter which is an upgrade of the dual-port splitter. It has one input port and four output ports. Some models can have LED indicators that show port activity. They are commonly used in control systems where one computer must control multiple devices.

Eight-port splitters have one input port and eight output ports. They are used in larger systems where one RS-232 signal must be distributed to eight different devices.

Eight-port splitters have one input port and eight output ports. They are used in larger systems where one RS-232 signal must be distributed to eight different devices. Some advanced models include LED indicators that show status for each output port.

Functions and Features

• Connection and Distribution:

  The main function of an RS232 splitter is to connect one RS232 device to multiple computers. For example, connect one scale to multiple cash registers or connect one card reader to multiple ATM machines. This reduces cable clutter. It is also used where multiple access points are needed, like accessing a modem from different computers. All information from the primary port goes to all secondary ports. Certain splitters allow information from a device to go to one of several computers. These splitters have buttons or software controls that let the user choose which computer to send data. Some models have features that keep the data cable straight, like automatic data switching or user-friendly cable management.

• Multiple Outputs:

  Various models are available for different distribution needs. This includes 2,4,8,16,32, and 64 port options. Eight ports are the most commonly used model.

• Provide LED Indicators:

  Some splitters have LED lights to show if data is being received and sent. This helps troubleshoot connection problems. Important splitter features include maintaining signal integrity, being bus-powered without needing an external power supply, and being compatible with different operating systems like Windows, Linux, and Mac. Two types of splitters exist: the first copies data to multiple ports, and the second sends data to one port that can switch between ports. This second type is also known as a data switch or data selector.

Applications of RS232 Splitter Box

Various industries that rely on serial communication employ rs232 splitters in their operations. They use it to facilitate the transmission of data to different locations.

• Data Distribution: An RS232 splitter can send data from a single source to multiple devices for monitoring and collaboration. This can occur in control rooms, labs, and other working environments.
• System Integration: An RS232 splitter can be handy while integrating new systems with existing infrastructure. Businesses can link one output device to other systems or devices using a splitter. This allows seamless data sharing between systems that may still be using the outdated RS232 standard and contemporary technologies that utilize more recent interfaces.
• Remote Access and Control: Another application of RS-232 splitters is remote access and control. These splitters offer a practical solution for applications that require centralized control, data logging, and remote operation.
• Telecommunications: RS-232 splitters can split an RS-232 signal into multiple paths in telecommunications systems. This allows dispatch and record-keeping systems to share data from a single source.
• Pin Reordering and Data Format Conversion: Pin reordering allows custom tailoring of connectivity requirements between devices. Not all RS-232 ports have the same pinout configuration on the DB-9 or DB-25 connector. Reordering the pins ensures that the devices can communicate properly.
• Data Acquisition: Industries that rely on data acquisition, such as environmental monitoring and industrial production, use RS232 splinter boxes. These applications all require converting analog signals from sensors into digital format, and RS-232 splitter boxes provide the solution.
• Point-of-Sale (POS) Systems: POS systems often include barcode scanners, payment terminals, and printers. All these devices can communicate via an RS-232 connector. If they are connected to a splitter, they can work together to streamline transactions.
• Mobile Command Centers: In military, emergency response, and law enforcement applications, command center involves monitoring various data sources in real time.

How to Choose RS232 Splitter Boxes

• Compatible Port:

  Having a similar connector is vital because, in the case of splitters, many will have a different type of port number than the one they are receiving the RS-232 signal not being converted but still able to be transmitted. Some common types are DB9 and DB25, but more often, one will see the DB9 being used, as it is the more standard and common number of pins for RS-232 connections. If one has equipment with a 9-pin DB and another with a 25-pin, an adaptor cable can connect between them to allow the splitter to work. This will provide compatibility between devices.

• Number of Outputs:

  A key factor is the number of outputs the splitter provides; this needs to be determined when making the purchase as to how many devices need to be connected to the splitter box. One will find that some splitters provide a one-to-one pass-through connection, while others may offer two, three, or even more output ports.

• Device Compatibility:

  Ensuring that the RS-232 splitter box is compatible with the devices to which it will be connected is necessary. Researching and contacting the manufacturer's tech support is a good idea before purchasing to ensure one is getting the right product. The user manual for the device may also have helpful information regarding connectivity options, including any port requirement.

• Controlled Output Ports:

  It is excellent if one can adjust the output ports on the splitter box. Controlling the output ports means changing, adjusting, or deciding which ports can be outputted to different devices can be helpful. Determining how one can adjust the output ports depends on the type purchased. Some require only dip switches to be set or software to be used, but using one, however, it is done, provides flexibility in deciding which devices will output the desired information.

• Attempts at Load:

  This is crucial and pertains to how many devices can simultaneously connect and transfer data, the max number, and the min. Taking into consideration the max and min, this will help one decide which splitter box to buy. When it says ''attempts at load,'' one must consider the max and min when deciding which box to buy because not every box has the same attempt at load. When looking at attempts at load from one box to another, understanding the max and min attempts is critical in choosing the right box.

• Important Features:

  When reviewing different types of RS-232 splitters, it is essential to look at the following:

  • Power supply - what is required of the splitter power supply
  • Cable length - how long can the cable be to connect the devices
  • Operating temperature - what temperature the environment must be for it to operate correctly.

  In reviewing these basics, one can quickly obtain a splitter that meets the needed criteria.
