Industrial Communication Solution – Schneider Electric TSXCUSB485 | TSX Premium Series
Where This Product Is Used
The Schneider Electric TSXCUSB485 is a USB to RS485 serial converter purpose-built for connecting a PC or laptop to Modicon TSX Premium and TSX Micro PLCs via the terminal port. It is deployed across a wide range of industrial environments where legacy RS485-based Schneider PLCs remain in active service:
- Automotive manufacturing lines – programming and diagnostics of TSX Premium controllers managing robotic cells and conveyor systems
- Water & wastewater treatment plants – remote configuration of pump station PLCs without dedicated RS232 ports on modern laptops
- Building management systems (BMS) – commissioning Modicon PLCs controlling HVAC, lighting, and access control
- Food & beverage processing – on-site PLC firmware updates and fault diagnostics in hygienic production areas
- Power distribution & utilities – interfacing with Modbus RTU networks for energy monitoring and substation automation
- OEM machine builders – standard programming interface included in service kits for TSX Premium-based machines

Why Engineers Specify This Model
- OEM-matched interface – designed by Schneider Electric specifically for TSX Premium terminal port; eliminates pin-mapping guesswork and signal-level mismatches common with generic USB-RS485 adapters
- Bus-powered convenience – no separate power supply; plug into any USB port and connect directly to the PLC terminal port
- Plug-and-play with Unity Pro & PL7 Pro – recognized automatically by Schneider programming software; no COM port remapping required in most configurations
- Robust industrial cable – shielded cable construction resists EMI interference common in panel environments
- Compact form factor – fits in a technician’s tool bag; ideal for field service and commissioning engineers
- Long-term availability – stocked as a service part to support installed base of TSX Premium PLCs still operating in production

Application-Specific FAQ
Q: Is the TSXCUSB485 compatible with TSX Micro PLCs?
A: Yes. The TSXCUSB485 supports the RS485 terminal port found on TSX Micro series PLCs in addition to TSX Premium.
Q: Do I need to install a driver?
A: Yes. A USB-to-serial driver (typically FTDI or Schneider-specific) must be installed on the PC. Driver files are available from Schneider Electric’s support portal or upon request from Konmask.com.
Q: Can this converter be used with Modbus RTU networks?
A: Yes. The RS485 interface supports Modbus RTU master/slave communication, making it suitable for connecting a PC to any RS485 Modbus network for monitoring or configuration.
Q: What is the difference between TSXCUSB485 and TSXPCX3030?
A: The TSXPCX3030 uses a DB9 RS232 interface (requires a separate USB-to-serial adapter on modern PCs), while the TSXCUSB485 connects directly via USB — the preferred choice for laptops without RS232 ports.
Q: Is this product available with a warranty?
A: All new-in-box units carry the standard Schneider Electric manufacturer warranty. Tested surplus units are covered by Konmask.com’s 90-day functional guarantee.
