RS-232 Asynchronous serial port providing a versatile interface for common

The screen captures below are taken from a Windows ME installation. Your
particular operating system may differ slightly from what is shown based on
your version of Windows.

The SeaLINK+232I can be connected to any Upstream Type “A” port either at
the PC host or an Upstream Hub. The SeaLINK+232I is hot-pluggable,
meaning there is no need to power down your computer prior to installation.
The SeaLINK+232I requires no user hardware configuration since there are no
jumpers present on the card.

1. After installing the software connect SeaLINK+232I to an Upstream Host

or Hub.

proceed to locate a driver.
