SystemBase uCAN V3.0 USB to CAN Converter — CAN 2.0A/B, 1Mbps, USB VCP

📋 Overview 📦 Special-Order · Ships in 1–2 Weeks The SystemBase uCAN V3.0 is an industrial USB to CAN Bus converter that lets any Windows PC or laptop connect directly to a CAN network — no network setup, no serial cabling, just plug in the USB cable and go. It supports CAN 2.0A and 2.0B communication at up to 1Mbps, and installs as a USB Virtual COM Port (VCP), so existing serial-based CAN software can use it immediately without modification. Configuration, testing, and monitoring are handled through CANView, SystemBase's GUI-based Windows utility — the same configuration tool used across the sCAN and eCAN converter family. Advanced users and developers get an optional CommandLibrary for building custom applications around data transmission, reception, save/load, and factory reset functions. 🎯 Applications — What Problems Does uCAN Solve? Not every CAN job needs a networked gateway — sometimes you just need to plug a laptop into a CAN bus and get to work. uCAN is built for exactly that: a fast, portable, plug-and-play bridge between a PC's USB port and a live CAN network. Field service and mobile diagnostics: Technicians can plug straight into a vehicle's or machine's CAN bus with a laptop for on-the-spot diagnostics, with no configuration required beyond installing the driver. Test bench and prototype development: Engineers developing CAN-based embedded systems can send, receive, and analyze CAN frames directly through CANView while debugging firmware or hardware. Drop-in replacement for legacy serial software: Since uCAN enumerates as a standard Windows USB Virtual COM Port, existing PC-side software written for serial CAN adapters works with uCAN without rewriting a single line of code. Data logging and fault capture: Use CANView to monitor and save CAN traffic to a file, useful for tracking down intermittent faults that only show up over time. Custom application development: Developers can go beyond the GUI with the CommandLibrary, building bespoke tools for transmission, reception, and device management around uCAN. Education and training labs: An affordable, portable way to give students or trainees hands-on access to a live CAN network without networking infrastructure. ⭐ Key Features USB to Virtual COM Port (VCP) — appears as a standard serial port once the driver is installed Supports CAN 2.0A and CAN 2.0B communication standards Maximum CAN speed of 1Mbps (50ms recommended interval between CAN frames) USB 2.0 Full Speed / High-Speed interface via USB Type A Integrated GUI-based configuration and test utility (CANView) CommandLibrary available for advanced/custom application development Power supply from USB VBUS or CAN VDD (pin 9) — no separate power adapter needed ABOR (Automatic Bus-Off Recovery) option for self-healing CAN communication Communication status checked via onboard LEDs (RDY, DATA, ERR) ±15KV ESD protection (air discharge) and a -40°C to 85°C operating range for industrial environments 📊 Specifications Product Type Industrial USB to CAN Bus Converter USB Interface USB Type A, USB 2.0 Full/High-Speed USB Cable Approx. 1200mm length, Ø4.8mm diameter USB Signals USB DP, USB DM, USB VBUS, GND CAN Interface DB9 Male, 1 port CAN Max Speed 1Mbps (50ms recommended frame interval) CAN Standard CAN 2.0A / 2.0B CAN Signals CAN_H, CAN_L, VDD (pin 9), GND Virtual COM Port Speed Up to 460.8kbps ESD Protection ±15KV (air discharge) Power Requirement 5VDC 500mA, approx. 0.60W consumption; USB VBUS or CAN VDD (pin 9) Dimensions Approx. 34.9 × 64.3 × 16.5 mm (1.37 × 2.53 × 0.65 inches) W × L × H Weight 26.1 g Configuration Utility CANView (Windows 7, 8.1, 10, Server 2008/2012/2016, 32/64-bit) LED Indicators RDY (Yellow), DATA (Green), ERR (Red) Operating Temperature -40°C to 85°C Storage Temperature -40°C to 85°C Humidity Max. 95% R.H., non-condensing 📦 What's in the Box 1× SystemBase uCAN V3.0 USB to CAN Converter 1× USB Type A to Type A Cable 📦 Special-Order Item This item ships from the manufacturer's existing factory stock rather than our own warehouse — which is why we can offer it at this price while still keeping delivery quick. We receive it first and ship it to you directly from Envistia Mall, with delivery typically taking ~1–2 weeks. Because it's ordered in specifically to fill your request, we're unable to modify, cancel, or return it once the order is placed. Have a question about compatibility or specs before you buy? Just message us — happy to help. 📌 Pinout / Pin Diagram USB Side: Standard USB Type A connector CAN Side (DB9 Male): Pin 2: CAN_L Pin 6: GND Pin 7: CAN_H Pin 9: VDD (5V) 🔧 Setup / Configuration uCAN uses a 4-position DIP switch on the underside of the unit to control power sourcing, operating mode, and CAN bus termination: Switch 1: ON = use CAN-side VDD as power (default) / OFF = VDD power disconnected Switch 2: ON = use USB VBUS as power (default) / OFF = USB VBUS power disconnected Switch 3: ON = Active Mode, normal operation (default) / OFF = Setup Mode, for configuring the device in CANView Switch 4: ON = enable 120Ω terminating resistor (default) / OFF = disable terminating resistor To change communication settings, install the USB VCP driver, set switch 3 to Setup Mode, connect with CANView at the fixed setup baud rate (115200, 8N1), and use the Setup Mode tab to configure the RS232/VCP baud rate, CAN baud rate, CAN spec (A or B), ID/Mask filtering, and ABOR option. Click Apply, then flip switch 3 back to Active Mode to put the new settings into effect. Note: If long cable runs are used or multiple devices share the CAN bus, enable the terminating resistor at both ends of the bus using DIP switch 4 — an unterminated or improperly terminated bus is one of the most common causes of unreliable CAN communication. 💻 Software CANView is the same GUI-based Windows utility used across SystemBase's sCAN, eCAN, and uCAN converter line. It handles device configuration, CAN frame send/receive testing, live data monitoring, and error counter tracking (TEC/REC/LEC) — all from one interface. Advanced users can go further with the optional CommandLibrary, which exposes lower-level functions for developers building custom CAN applications. 💡 Tips Install the USB VCP driver before connecting uCAN for the first time so Windows assigns it a COM port automatically. If the RDY LED stays constantly on or off after booting instead of blinking, the device may be malfunctioning — check the power source and USB connection. If CAN frames appear corrupted or the device misbehaves after a bad ASCII frame passes through, cycle power to the unit (toggling DIP switches 1 and 2 off and back on is a quick way to do this). Use Setup Mode (DIP switch 3 OFF) to change settings, then switch back to Active Mode (ON) to apply and use them — CANView will only operate correctly when the hardware and software settings match. 🚫 Limitations Single CAN port and single USB port per unit — this is a one-to-one converter, not a multi-channel interface. CANView configuration software requires Windows 7 or later. This device is intended for industrial use (Class A) and is not intended for use in a home or residential environment. 📄 Documentation & Resources Spec Sheet — Full technical specifications and pin diagram User Manual — Hardware setup, CANView configuration, driver install, and troubleshooting Manufacturer Product Page — SystemBase uCAN All CAN Bus Converters Sold and supported by Envistia Mall.
