Introduction
Introduction
Overview
The Sealevel Systems SeaPORT+4 equips the PC with 4 USB to
RS-232/422/485 Asynchronous serial ports providing a versatile interface for
common serial needs. The advantage of this product over more traditional
approaches is that it does not require opening the computer case, nor does it
require resources such as I/O ports or IRQ’s. It does require a system that
supports USB both in terms of hardware and operating system.

The SeaPORT+4 is sh ipped with the following items. If any of these items is
missing or damaged, contact the supplier.
• SeaPORT+4 USB to RS-232/422/485 Serial I/O Adapter

Operating System Installation
Choose Install Software at the beginning of the CD and install SeaCOM.
System Installation
The screen captures below are taken from a Windows 98 installation. Your
particular operating system may differ slightly from what is shown based on
your version of Windows.
The SeaPORT+4 can be connected to any upstream type “A” port either at the
PC host or an upstream hub. The SeaPORT+4 is hot pluggable, meaning there
is no need to power down your computer prior to installation.
Connect the SeaPORT+4 to an upstream host or hub.
The New Hardware Found wizard will now proceed to locate the appropriate
drivers. These drivers were installed during the SeaCOM software setup
procedure. Once the drivers are found a new window will pop up indicating the
installation of each of the four new ports.
If you view the system’s Device Manager, you should have new “COM” ports
in the Ports (COM & LPT) Device Class. This is shown on the following page.

Installation
You can access your new COM: ports by using the assigned COM: identifiers as
shown above. In this case, it is COM3, 4, 5 and 6. However, this assignment
will vary from system to system. At this point, the hardware is recognized and
ready to use.
