Download Communications Port Com1 Driver HOT!

The cable you are trying to use is a serial-to-USB converter. You would have to install a driver for such a device. The driver would then emulate a COM port, but these devices are notoriously hard to get working right because USB ports are inherently plug-and-play, but serial ports are not (they existed long before Windows).

If your computer actually has a real serial port on it, then that's the COM1 you're seeing, and of course the software wouldn't be able to use it because it isn't connected to that port. The driver for the device should be emulating a COM2 or something similar.

According to the K+DCAN USB Interface Driver Installation Manual once you install the drivers on the PC you should then find a new Virtual Comport which you will need to open the Advanced properties on within Device Manager and configure accordingly from there as per those steps or whatever you can get to work if this isn't the specific cable you have. This is the same area you can specify the COM port to use as well once you free up COM1 per the previous steps, you can then assign this one to COM1.

Virtual COM port (VCP) drivers make USB devices appear as additional COM ports that the PC can access. USB devices can be accessed by application software similarly to how it would access standard COM ports.

Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the This page contains the VCP drivers currently available for FTDI devices.

Virtual COM port (VCP) drivers cause the USB device to appear as an additional COM port available to the PC. Application software can access the USB device in the same way as it would access a standard COM port.

For most devices, the Ports device setup class and the Serial function driver provide the functionality required to operate serial ports and COM ports. To install serial ports and COM ports using these system-supplied components, do the following:

Now that you have the driver installed, try unplugging the digirig from your computer, then plug it back in again. When you connect the digirig to the computer, it should show a new device is being connected (popup window in the lower right corner of the screen), and then tell you when it is ready. At that time, check again in the device manager to see if the CP210x driver installed. If it did, you are probably good to go, but before you leave device manager, make a note of the COM port that it assigned to the digirig - you will need that number to set up your software.

I would right click on the start menu and click computer management. If there is an exclamation point next to the sound card under ports, then try right clicking and updating the driver (with the one you downloaded) through the properties menus.

If the motherboard drivers are too outdated, they will also lead to COM ports missing in Device Manager. Therefore, you are advised to update your motherboard drivers manually and see whether it works.

I originally started developing with the LPC2368 beta unit on a Windows XP machine. All was working fine with the Windows serial port driver. When the new (current) driver was released, I started using that and it wored fine. I then added a Vista machine to my office. I then loaded the new drivers onto the Vista machine and all worked fine.

I then tried to run the LPC1768 on my XP machine, and again found I had to re-load the Windows Serial Port Driver. When I did, Windows reported that there was a problem and could not start the serial port driver. I tried re-installing it several times, both from the website as well as from a local drive copy. Finally, I went back to my LPC2368 mbed. Re-installed drivers, and everything works fine. Going back to the LPC1768, it fails. It always says the driver could not start. I have uninstalled, re-installed, etc., but to no avail.

Are you attaching the USB-to-Serial device to the host, and selecting the COM port to attach to the Serial port of the VM? Or are you attaching the device to the VM, and having the drivers installed in the VM, etc.?

I found solution. After removing Printer from VM settings, everything works good with my communicatios. So, there is some conflicts between virtual printer which occupies serial port 1 and serial port driver.

Most serial communications designs send the data bits within each byte least significant bit first. Also possible, but rarely used, is most significant bit first; this was used, for example, by the IBM 2741 printing terminal. The order of bits is not usually configurable within the serial port interface but is defined by the host system. To communicate with systems that require a different bit ordering than the local default, local software can re-order the bits within each byte just before sending and just after receiving.

The second interface (Photon Control Interface) is not actually a COM port, but a WinUSB interface for vendor requests, and should also have been automatically enumerated by Win 10 with WinUSB driver. It actually even shows that in Zadig: WCID (checkmark) WINUSB.

With the hub4com (HUB for communications,part of the com0com project ) it is possible to handle data and signals from a single serial device by a number of differentapplications (for example, several applications can share data from one GPS device).It's also possible to use the real serial ports of remote computer like if they exist on a local computer.

HW VSP is a software driver that adds a virtual serial port (e.g. COM5) to the operating system and redirects the data from this port via a TCP/IP network to another hardware interface, which is specified by its IP address and port number. HW VSP3 support even NT Services and 64 bit Windows 8 .

HW Virtual Serial Driver is intended primarily for devices produced by HW group, although it can be used for free as a universal driver that creates a virtual remote serial port, which redirects data to a predefined TCP/IP address and port.

In special applications (e.g. involving GPRS devices), the PC with the HW VSP driver can be set to operate in TCP Server mode, enabling the remote device to initialize the connection by sending any data to the remote port. Upon receiving RS-232 data, the converter establishes a connection with the PC and passes the data to the virtual COM port. Therefore, the scenario very closely resembles behavior of a real serial port.

Note: If configuring for native shutdown via Control Panel - Power Options, the driver should be HID UPS Battery. If PowerChute had previously been install, the drive would be APC UPS.

3. From the Device Manager, select Human Interface Devices (HID). You should see a driver called American Power Conversion USB UPS. If either HID or this driver does not display, proceed with the steps below.

4. Ensure the USB port is enabled in your computer BIOS. Consult your computer documentation for details on how to enable the USB Port.

5. If your installation includes a USB hub (a device that multiplies the number of USB ports available) and the UPS is plugged into it, check that the hub is receiving power. Check your hub's manual to learn whether the hub should be powered with an AC/DC adapter.

Note: APC recommends that the UPS USB cable be plugged into the PC's USB port directly, not into a USB hub for optimum performance.

6. Ensure that the USB cable connected to the UPS is the last in the chain (downstream). Ensure all other USB devices upstream from your APC UPS have communication. If an upstream device is not communicating, any downstream device may not communicate. Remove the device that is not communicating and see if that has any effect.

7. You can review all connected USB devices Using a freeware utility such as USBDeview.exe. See Schneider Electric FAQ283181 Video: How to verify USB communications between UPS and Windows OS using UsbDeview.exe

8. If the USB drivers have loaded properly and USBDeview.exe can discover the UPS yet PowerChute cannot discover the UPS, uninstall PowerChute, and reset the communications bus.

a. For an SMT, SMTL, or SMX model UPS, on the display interface, hold the UP and DOWN buttons simultaneously for 10 - 12 seconds. The display flashes to indicate that the network interface has restarted.

b. To reset the communications bus of an SMC model UPS, on the display interface, hold the MUTE and MENU buttons simultaneously for 10 - 12 seconds. The display flashes to indicate that the network interface has restarted.

c. To reset the communications bus of an SCL model UPS, insert paperclip into the reset hole on the rear of the UPS.

d. For all other Smart-UPS, power down all equipment connected to the UPS, and cold start/brain-dead the UPS. For assistance with performing the cold start/brain dead procedure, see Schneider Electric Video: How to perform a cold start and brain dead on Smart-UPS.

9. On SMT and SMTL model UPS, disable Green mode. To disable Green mode from the UPS LCD panel go to Configuration - Green Mode

10. Disable Selective Suspend Settings within the OS power options. To disable USB selective suspend open the control panel. Go to power options, select change plan settings, change advanced power settings, USB settings

11. After resetting the communications bus or restarting the UPS, reinstall PowerChute. When reinstalling, when asked, "Would you like to automatically search all communication ports for a UPS?" select No. In the next screen, when asked to "Select your UPS Model:" from the drop-down select "Other Type-A" if your UPS model is an SMT, SMX, SMC, SMTL, SRT, SCL. If the UPS model is SUA, select "Other Type-B". In the next screen, when asked, select USB as the com port.

NOTE: For step 11 to work, PowerChute would need to have been previously installed on the system. If not the required APC UPS driver will not be available. See Schneider Electric FAQ Video: How to restore APC PowerChute device drivers on Windows? for assistance with loading the APC UPS driver.

Troubleshooting Windows Serial Communications

Try debugging the COM port with a tool like PuTTY.

For Smart-UPS models SU and SUA. See the "Checking UPS Communications on Windows" section of the attached PowerChute Business Edition Installation Guide for more information.

When configuring PowerChute Agent to communicate using simple signaling the UPS will not be discovered automatically. When running the installer, the UPS must be added manually. 2351a5e196
