SMUGDESK USB to RS485 Converter Adapter 485 WinCE5.0

SKU CH-5AYA-45C5M

Converts USB to RS485 for Modbus RTU industrial devices with WinCE5.0 support

  • Wide OS support: Win7, WinCE5.0, XP, Vista, Linux, Mac OS
  • USB bus powered, no external supply needed
  • Screw terminal blocks for secure A/B wiring
  • Built-in ESD and surge protection for noise immunity
  • Modbus RTU ready for PLC, inverter, sensor integration

Industrial USB-RS485 Bridge

This USB to RS485 converter adapter translates USB signals into standard RS485 differential signals, enabling direct serial communication between a host computer and industrial field devices. It is designed for engineers and technicians who need a reliable link for PLCs, inverters, sensors and Modbus RTU meters in automation or data-logging tasks.

OS Coverage & Power Constraints

The adapter supports Windows 7, Vista, XP, WinCE 5.0, Linux and Mac OS, covering both standard PCs and embedded industrial panels. It draws all power from the USB port, so it fits cabinets without spare mains outlets, but it will not serve systems that require an isolated power supply or optical isolation on the bus.

Built-In Surge & ESD Protection

On-board surge suppression and electrostatic-discharge circuits protect the converter and the host from transients common on long RS485 cable runs in electrically noisy plants. This protection is the key spec that determines whether the module survives the target installation.

Highlights

  • USB bus powered, no external supply needed
  • Screw terminal blocks for secure A/B wiring
  • Built-in ESD and surge protection for noise immunity
  • Modbus RTU ready for PLC, inverter, sensor integration

Questions about this item

Will the USB to RS485 adapter work with my existing PLC and inverter that use Modbus RTU?

Yes, the converter supports standard Modbus RTU protocol and is designed for PLCs, inverters, sensors and industrial meters, connecting via the RS485 A/B terminal block.

How can I verify the RS485 link is active after wiring the A and B lines?

The adapter is USB bus powered so the host will enumerate a COM port when plugged in; open a terminal or Modbus master tool at the correct baud rate and poll a known register on the connected device to confirm communication.

Does the package include the screw terminal block for field wiring or must I buy it separately?

The screw-type terminal block for A/B signal lines is built into the converter, so no separate connector purchase is needed for basic RS485 field wiring.
