Product information

Description

The product is plug-in after software installation and is compact for desktop or mobile use.

Suitable for

  • Adding extra RS232 ports for legacy hardware on modern PCs and laptops
  • Use in offices, workshops, or field service where serial interfaces are required

How to use

First install the driver software provided by the manufacturer or available from the vendor website. After the software installation is complete, connect the adapter's USB plug to an available USB port on your computer and attach your RS232 devices to the two 9-pin Sub-D connectors.
