How to Install Redsail Cutting Plotter USB Drivers: A Complete Guide

Getting your Redsail cutting plotter to talk to your computer can sometimes feel like a puzzle, especially with USB connections. Because Redsail machines typically use a USB-to-Serial interface, the setup requires a specific driver to create a "Communication Port" (COM Port) that your design software can recognize.

Whether you are using an RS360C, RS720C, or RS1360C, follow this guide to get your driver installed and your blades moving. Step 1: Download the Correct Drivers

Redsail plotters generally use the FTDI or CH340 chipset for USB communication.

Check your provided disk: If you still have the original software CD, the driver is usually located in a folder named "USB Driver" or "Driver."

Download online: If you don't have a disk, search for the Redsail USB Driver (FT232 or CH341). Most modern Windows versions (10 and 11) require the 64-bit version of these drivers. Step 2: Running the Installation

Before plugging the plotter into your PC, it is often better to run the installer first: Extract the downloaded ZIP folder.

Right-click on the Setup.exe or Install.exe file and select Run as Administrator.

Click "Install" or "Extract." A "Driver Installation Successful" message should appear within a few seconds. Step 3: Connecting the Hardware

Now, connect the USB cable from your Redsail plotter to a USB port on your computer and power the machine on.

Open the Device Manager on your PC (Right-click the Start button > Device Manager). Look for a section called Ports (COM & LPT).

You should see an entry like "USB Serial Port (COM3)" or similar.

Note: If you see a yellow exclamation mark under "Other Devices," the driver did not install correctly. Step 4: Configuring Your Cutting Software

Even with the driver installed, your software (Artcut, SignCut, Flexi, or CorelDraw) won't work unless it knows which port to use.

In your software’s Cutter Settings or Device Setup, look for the "Port" or "Output" menu.

Change the port from LPT1 or COM1 to the exact COM port number you saw in the Device Manager (e.g., COM3).

Set the Baud Rate (Sequential speed). For most Redsail models, the standard is 9600 or 38400. Ensure the Flow Control is set to Hardware or Xon/Xoff. Troubleshooting Common Issues "Device Not Recognized"

If Windows doesn't see the plotter at all, try a different USB port. Avoid using USB hubs; plug the cable directly into the back of the computer (for desktops) to ensure it gets enough power. The Plotter Starts then Stops redsail cutting plotter usb driver install

This is usually a "Static" issue or a "Flow Control" mismatch. Ensure your USB cable is shielded and that the COM port settings in the Device Manager match the settings in your software exactly. Driver Signature Error (Windows 10/11)

Some older Redsail drivers aren't "signed" by Microsoft. If the installation fails, you may need to temporarily Disable Driver Signature Enforcement in your Windows Recovery settings to allow the install to finish.

By following these steps, your Redsail cutting plotter should be fully operational. Once the COM port is stable in your Device Manager, you’re ready to start cutting.
