Hardware Stability: Usually features a PIC18F458 or PIC18F45K80 chip and an FTDI USB-to-serial converter for stable communication. Windows 10 Compatibility & Challenges

Running this software on Windows 10 is notoriously tricky because the drivers are often unsigned.

Step 1: Disable Driver Signature Enforcement

Windows 10 enforces strict security on drivers. The Opcom clone drivers are usually unsigned. You must disable this feature to install the driver.

  1. Press the Start button and click the Power icon.
  2. Hold the Shift key on your keyboard and click Restart.
  3. The PC will reboot into a blue menu. Select Troubleshoot > Advanced options > Startup Settings.
  4. Click Restart.
  5. When the PC reboots, you will see a list of options. Press F7 (or the number 7 key) to select Disable driver signature enforcement.
  6. Windows will now load normally, allowing unsigned drivers.

Part 2: Installing the Driver

  1. Plug your Opcom interface into a USB 2.0 port (Avoid USB 3.0 hubs if possible, as they can cause communication lag).
  2. Open Device Manager (Right-click Start button > Device Manager).
  3. Look for a device under "Other devices" usually named "VAUX-COM" or "USB Device" with a yellow exclamation mark.
  4. Right-click the device and select Update driver.
  5. Select Browse my computer for driver software.
  6. Click Browse and navigate to the extracted folder where you saved the software. Look for a folder named Driver or USB_Driver.
  7. Click Next. Windows may warn you about an unsigned driver; click Install this driver software anyway.
  8. Once installed, the device should appear under Ports (COM & LPT) as "USB Serial Port".

Method 1: The "Compatibility Mode" Fix (Easiest)

For most OPCOM 199 utilities, this is all you need.

  1. Locate OPCOM199.exe or Setup.exe.
  2. Right-click the file > Properties.
  3. Navigate to the Compatibility tab.
  4. Check "Run this program in compatibility mode for:" and select Windows XP (Service Pack 3) or Windows 98 / Me.
  5. Under Settings, check:
    • Reduced color mode (16-bit) – Often required for old OPCOM interfaces.
    • Run this program as an administrator.
  6. Click Apply > OK.
  7. Run the installer.

Method 3: The Legacy Hardware Hack (For Serial/COM Issues)

OPCOM 199 often fails because Windows 10 labels COM ports differently.

  1. Plug in your USB-to-Serial adapter.
  2. Open Device Manager (Right-click Start button).
  3. Expand Ports (COM & LPT).
  4. Right-click your adapter > Properties > Port Settings tab.
  5. Click Advanced.
  6. Change the COM Port Number to COM1 or COM2 (OPCOM 199 rarely looks beyond COM4).
  7. Pro tip: Lower the "Latency Timer" to 1 ms for better stability with old industrial protocols.
