Common features

LED Status indicator

Display of the device status and (field)bus communication via multi-functional LED(s). Direct control of the data stream, easy check for correct connection and activation.

Adaptable baud rates

New FTDI chip generation allows also the adjustment of non standard baudrates. Selected driver components provide best transmission properties.

COM Port compatible

Full PC compatibiliy by transparent access via virtual COM port, for instance COMx (Windows) resp. /dev/ttyUSBx (Linux).

What type suits you best

USB to RS232

USB232CONV - Extra large protection

No more undefinable converter breakdown when connecting RS232 devices because of ±15 kV against ESD, short-circuit proof, high current load ±60 mA.

USB to Isolated RS232

ISO232 - 1 Mbps with active outputs

High isolating strength for safe connection of potential shifted devices. Active RS232 outputs by integrated energy transfer. No additional power supply necessary.

USB to Isolated RS485

ISO485 Box/Cable - Universal and safe

A lot of setup possibilities cover a wide range of RS422/RS485 bus applications. By their high isolating capability they are usable in critical environments with potential shift.
