To begin, click the start menu and type 'Device Manager' and click the Device Manager link. Without your USB to serial adapter plugged in, your Device Manager should look something like below. Plug your USB to serial cable into your PC's USB port. Chances are the drivers are already installed. Look for it to show up under 'Ports (COM & LPT)'. Provide an INF file that specifies the Ports device setup class and the Serial function driver as the service for the port. To configure a serial port as COM port, comply with the requirements that are defined in Configuration of COM Ports.
The following procedure works with all of our cables including the Allen Bradley 1747-UIC, 1761-CBL-PM02, 1747-CP3, and 2711-NC13

1. To begin, click the start menu and type 'Device Manager' and click the Device Manager link.

2. Without your USB to serial adapter plugged in, your Device Manager should look something like below.
3. Plug your USB to serial cable into your PC's USB port. Chances are the drivers are already installed. Look for it to show up under 'Ports (COM & LPT)'. If it does, then note the COM number at the end of the description and proceed to the software you are using it in. If it doesn't show up under 'Ports (COM & LPT)' then proceed to step 4.
4. If your cable does not show up under 'Ports (COM & LPT)' of the Device Manager then you need to install the drivers. They can be found in the PLC Cable Drivers section of our Drivers, Software, and Manuals page. Download them and extract the zip file to your PC.
5. Navigate to the 'Drivers for manual installation' folder and you will find two folders named CH340 and CP210.
6. Double click on the CH340 folder and you will find an EXE file in it. Right click it and select 'Run as Administrator'. Note that this will not work by double clicking the EXE file.
7. Now navigate to the CP210 folder and then to the CP210x_VCP_Windows folder. You will see two EXE files, one for 32 bit and one for 64 bit. Right click the one that matches the processor of your PC and Right click it and select 'Run as Administrator'. Note that this will not work by double clicking the EXE file.
-->Device Manager provides a Details tab for each device. This tab displays lots of information useful to driver developers and testers, and aids Microsoft Customer Support Services (CSS) in diagnosing customer problems. The tab's page displays device identification strings, together with device and driver configuration information that can be useful when you debug drivers.

The details tab is enabled by default. To enable this tab, set the user environment variable DEVMGR_SHOW_DETAILS to 1. After you set this environment variable, the Details tab of the device will be available in Device Manager. To permanently set a user environment variable, use the Advanced tab of the system property sheet.

Device Manager's Details tab can display a device's firmware revision number, if available. A driver can supply a firmware revision number by responding to a WMI request. Specifically, the driver's DpWmiQueryDataBlock routine should support MSDeviceUI_FirmwareRevision_GUID by returning a DEVICE_UI_FIRMWARE_REVISION structure (defined in Wmidata.h). The structure must contain the firmware revision number as a NULL-terminated WCHAR string, preceded by a USHORT value that contains the string length (including the NULL).
