Comparison of different RoMI/O models
Over time, ESI has released a number of different products with the RoMI/O name. This text explains about the differences. The different models are described first, followed by a table that mentions the differences of them.
RoMI/O consists of 3 cables with male DIN connectors connected to a plastic case which has a USB connction cable on the other end. The cables are either gray (in that case the inside of the plastic case is gray/silver) or white (in which case the inside of the plastic case is also white). It looks like visible on the picture above.
RoMI/O II consists of a round plastic case that has two female DIN connectors and a USB cable on one side and two male DIN connection cables on the other. The cables are transparent / silver while the PCB inside the transparent plastic case is white. Please note that there are two hardware revisions of RoMI/O II, Rev A and Rev B. Which one you have can be identified by checking the rating sticker on the bottom of the unit. The following picture shows the sticker of either version:
The revsion B has Rev B written at the bottom of the sticker. If you are still unsure or if the sticker is not readable or has been removed, the PCB of Rev A and Rev B looks different. While you can see metal like small circles on Rev A on many internal connectors, they are mostly covered in white paint on the PCB of Rev B.
The following table shows the important differences between these versions:

"native" means that no driver installation is required and that no driver is available for download. You simply plug in the cable to the computer and the built-in support of the operating system for so-called class compliant devices supports the interface.
"optional driver" means that although the device is supported by the built-in driver for the operating system, we provide a driver for download that can be installed.
"via driver" means that a driver is required for the interface to work on that particular operating system.
