Description

The USB-2COMi PRO is an innovative Industrial USB to dual-port serial adapter designed completely jumperless and free of any DIP switch for easy configuration. A user-friendly configuration program of Windows and Linux is provided to allow users to select and set easily the COM ports to any RS-232, RS-422 or RS-485 mode with various operation mode options. Just connecting your computer to the Internet, plugging the adapter to the USB port on the PC, then you let Windows install the driver automatically. You do not need to install the driver manually. There are no IRQ or COM port conflicts, since the serial port does not require any additional IRQ, DMA, memory as resources on the system.

Pressing the button near the DE9 male connector to activate the configuration mode, user can set the port to RS-232, RS-422, or RS-485 from the graphic interface on the screen. Besides the classical RS-232 and RS-422 port, the adapter offers three variants of RS-485 modes for user’s selection to meet different application needs. Built-in termination and biasing option are available for data transmission lines. Free from opening the metal chassis, users can conveniently configure the operation mode of RS-232, RS-422 or RS-485 serial port, enable or disable Tx, Rx termination resistors and biasing resistors by the provided configuration utility.

USB-2COMi PRO provides a unique feature of Remote Serial Port Sharing that allows to share the serial ports and devices to other users in the network. It breaks the distance limitation of traditional serial ports and USB. When the AnyplaceUSB app activated, you can network-enable the adapter and make the serial ports available to other users in the network. You can share the serial ports and the connected serial devices to multiple client computers in the network. USB-2COMi PRO adapter makes it easy to network- enable serial devices, and allows remote RS-232, or RS-422, or RS-485 serial devices to be shared, accessed, monitored and used over the network, as if the distant serial devices were locally and physically connected to the standard COM port on the host computer.

The USB-2COMi PRO Industrial USB to RS-232/422/485 Adapter provides instant connectivity to RS-232, RS-422, RS-485 communication devices for POS, factory automation equipment, multi-drop data collection devices, bar code readers, time clocks, scales, data entry terminals, PC to PC long distance communications, ATMs and serial communication in harsh environments. The USB-2COMi PRO Adapter provides industrial solution requiring single node or multi-drop communications over short and long distance in the network.

  • How can I change my device’s COM port?
      1. Click on Start and navigate to the Control Panel
      2. Locate and click on Device Manager
      3. Under “Ports (COM & LPT)” you will find your serial device titled “USB Serial Port” along with its current COM Port.
      4. Right click on “USB Serial Port” and click on Properties.
      5. Navigate to the “Port Settings” tab and click on “Advanced…”
      6. Once there, the “COM Port Number:” can be changed with a dropdown menu to select the port number.
      7. Click your desired port number (i.e. COM2) and click “OK”.
      8. Click “OK” once more.
      9. Your serial device is now assigned to your chosen COM Port.

     

  • How do I check to ensure the COM port is listed properly in Windows?
    To ensure your serial device is installed properly, complete the following:

    1. Press Windows Key + R to open the Device Manager. Once Run comes up, type “devmgmt.msc” into the text field and press Enter.
    2. Expand the section labeled, Ports (COM & LPT).
    3. You should now see a COM number in brackets to the right of each port. If the device is installed properly, no exclamation points or question marks should be present next to the device.
  • I have everything hooked up, but nothing is functioning correctly.
    To rule out potential issues, quickly test your individual components to ensure that they are working correctly individually, and are not the source of the problem:

    • Serial cables
    • Serial ports
    • Serial devices

    Test your components by:

    • Hook up the serial cable(s), serial port(s), and serial device(s) in a different setup to see if the issue stems from a particular component, or the setup as a whole.
    • Replace the serial cable, port, or device within your setup to further troubleshoot the issue’s origin.

    When testing cables:

    • Test each cable individually.
    • Use short cables when you are testing.

    When testing serial ports and devices:

    • Press the Windows key + R, in Run, type devmgmt.msc, and press Enter to open the Device Manager. You can then check to see if your device is listed under Ports (COM & LPT).
    • Ensure that the COM port number is the correct number for the serial device and that the software being used to connect the computer to the serial device uses the correct COM port number.
    • If the device is listed with an error, follow the instructions on the website to reinstall the drivers.
  • Serial communication is not functioning correctly, how can I tell if the problem caused by the adapter or my serial software application?
    Older serial communication applications make use of legacy hardware addresses, often incompatible with PCI, PCIe, and USB to Serial products. Contact the software provider to troubleshoot.
  • I am receiving an error when I try to install the drivers in Windows 8 64 bit.
    Driver Signature Enforcement in Windows 8 may need to be disabled in order to use various drivers. After disabling this feature, the driver will be allowed to install.
