: For the legacy I-7561 (Prolific), use the pl2303 module. The USB Vendor ID (VID) is 0x1B5C and the Product ID (PID) for the I-7561U is 0x0104 .
In conclusion, the ICP DAS I-7561 represents the necessary evolution of industrial connectivity. While the hardware provides the physical link, the driver remains the intellectual bridge that enables complex automation software to interact with the physical world. For any professional working in systems integration, maintaining an up-to-date driver for the I-7561 is a foundational practice that ensures the longevity and efficiency of industrial communication networks.
As he was walking to the kitchen, he stumbled upon an old notebook on the shelf. It was an old notebook that he had used during his college days, and it was filled with scribbled notes and diagrams. As he flipped through the pages, he stumbled upon a page with a crude drawing of the ICP Con I-7561 device.
You can also find the driver on the ICP DAS product page: www.icpdas.com → Search “I-7561” → Support → Driver
The primary reason for this transition is the phase-out of the older USB bridge chip used in the original models. To continue providing a solution with modern support, ICP DAS has introduced the as the official replacement. This new model is the recommended path forward for both new installations and future-proofing existing setups.
The I-7561 module features an internal self-tuner ASIC chip that automatically controls the sending and receiving directions of the RS-485 signals. Because it draws power directly from the USB port, it does not require an external power adapter. USB 1.1 and 2.0 compliant Output: RS-232 (3-wire), RS-422, and RS-485 Isolation Voltage: 3000 VDC on the serial side
| Problem | Solution | |------------------------------------------|-------------------------------------------------------------------------------------------| | “Driver not signed” error on Win 10/11 | Temporarily disable driver signature enforcement (see Step 2). Or use latest driver v2.10+. | | Device shows “Code 10” (cannot start) | Reinstall driver. Try different USB port. Ensure no USB 3.0 power issue – use USB 2.0 port. | | Device appears as “Unknown Device” | Unplug I-7561 → Delete unknown device in Device Manager → Reinstall driver → Plug device. | | COM port number too high (>16) | Change COM port number in Device Manager → Port Settings → Advanced → COM Port Number. | | Cannot communicate with CAN bus | Check CAN baud rate matches bus (default 250k or 500k). Verify wiring: CAN_H, CAN_L, GND. |
Match the , Data bits , Parity , and Stop bits to your target serial device configuration.
: Heavy-duty 3000 VDC galvanic isolation on the serial side shields the host computer from harmful ground loops and spikes.
Hello,
Do not connect any industrial serial devices (such as PLCs, flow meters, or RTUs) to the converter's terminal block before running the setup. Keep only the basic USB connection active to isolate potential signaling errors during initialization. Phase 2: Official Driver Download Sources
"Thanks, John. You're a lifesaver!" Mark exclaimed.
3000 VDC isolation protection on the RS-485/422 side.
Prevents communication errors and data loss.
