PT1801 Driver Installation Diagram

Common Issue: Driver Installation Failure

If you see an error like "Driver install failure!" as image below, see troubleshooting steps below:

Solution: Reinstall the USB driver:

1. Unplug the mini-USB cable from PT1801

2. Plug it back firmly

3. Reinstall the driver again

4. Turn PT1801 OFF and ON again

5. Reconnect PT1801

6. Check "Device Manager" → Ports (COM & LPT)

You should see something like:

USB-SERIAL CH340 (COMxx)

Try another USB port or another data cable

• Some ports block unsigned drivers

• Some cables are charging-only

---

Step 3 - Verify Driver Status in Device Manager

Ensure the CH340 USB driver is installed and visible under:

Start → Device Manager → Ports (COM & LPT)

You should see:

USB-SERIAL CH340 (COMxx)

If visible → your driver is working

If NOT visible → PT1801 is not recognized (see troubleshooting).

Common Issue: PT1801 Does Not Appear Under COM Ports

If PT1801 is NOT visible, try troubleshooting options below:

• Unplug and reconnect PT1801

• Restart PT1801

• Use a different USB data cable (not a charging cable)

• Try another USB port on your PC

• Reinstall the driver again

• Test on another computer

If still not detected → it might be hardware USB chip issue (repair needed)

Important: If PT1801 is still not showing, check whether the driver is installed correctly — an incomplete driver installation can prevent it from appearing.

Step 4 - Open PT1801 Configurator V1.5

1. Run the software

2. Click Connect button

If the connection is successful, you may now:

• edit ringing schedules

• configure weekly events

Common Issue: PT1801 Shows "Time Out"

Here's how to fix when PT1801 software shows "Time Out" on Windows 10/11:

• Reassign PT1801 to other available COM ports

• Reconnect USB cable to PT1801 (Try another data cable if it's not working)

• Restarting the software

Common Issue: Driver Pre-Installed in PC / Laptop

If you see this message, it means the CH340 USB driver is already installed in your system, but the PT1801 may not be connected during installation.

When to Consider an Upgrade

PT1801 is discontinued, and Windows updates may eventually stop supporting older drivers. We encourage users to upgrade to current models for improved reliability and long-term support.

Upgrade to PT1801 MK II is recommended if:

• PT1801 still does NOT appear in Device Manager

• USB port becomes unstable

• Likely USB communication chip failure

• Drivers stop installing after Windows updates

• Software not detecting PT1801 at all

• Repeated "Time Out" issues occurred
