Introduction

The Sealevel Systems SeaLINK+8/232.RJ (Item# 2804) is a USB device that equips the PC with eight RS-

232 Asynchronous serial ports that support TX, RX, RTS, and CTS and data rates up to 115.2K baud. The

2804 is housed in an attractive plastic enclosure with a high-retention USB type "B" connector that prevents

accidental disconnection of the included USB cable.

The 2804 is USB bus powered, so no external power supply is required. For conveniently powering serial

peripherals, ordering options allow an external power source up to be connected to a DC jack on the rear of

the unit. The supplied power is fused and connected to pin 5 on each of the eight RJ45 connectors.

The SeaLINK+8/232.RJ is designed to be used with a variety of Operating Systems including Windows

98/ME/2000/XP. The SeaCOM API (Application Programmer Interface) included on CD with the

SeaLINK+8/232.RJ provides a variety of useful high-level function calls implemented as a Windows

dynamic link library (DLL). In addition to the API, SeaCOM includes sample code and utilities to simplify

software development.

Software Installation Instructions

Windows 98/ME/2000/XP/Vista™ Operating Systems

Do not connect the device to a USB port until the software is installed.

1. Begin by locating, selecting, and installing the correct SeaCOM software from the Sealevel software

driver database.

2. Select the Part Number (2804) for your device from the listing.

3. The setup file will automatically detect the operating environment and install the proper

components. Follow the information presented on the installation screens that follow.

4. A screen may appear with the declaration: “The publisher cannot be determined due to the

problems below: Authenticode signature not found.” Please select the ‘Yes’ button and proceed

with the installation. This declaration simply means that the Operating System is not aware of the

driver being loaded. It will not cause any harm to your system.

5. During setup, you may specify installation directories and other preferred configurations. This

program also adds entries to the system registry that are necessary for specifying the operating

parameters for each driver. An uninstall option is included to remove the driver and all registry/INI

file entries from your system.

6. Proceed with the physical installation of your SeaLINK USB serial adapter.

Windows NT is not USB aware and thus cannot support this device.

Physical Installation

The SeaLINK+8/232.RJ can be connected to any spare USB port.

Do not connect the device to a USB port until the software is installed.

1. Connect the SeaLINK+8/232.RJ to a USB port with the supplied CA179 USB device cable.

2. The software drivers installed during setup will automatically recognize and configure the device.

3. You should see one or more “New Hardware Found” windows, indicating the actual device being

created.

The installation will repeat twice for each COM port (a total of 16 times on the SeaLINK+8/232.RJ).

This is a limitation in the way Windows installs external serial devices.

4. Next, view your system’s Device Manager.

5. You should have new COM: ports in the Ports (COM & LPT) Device Class indicating the installation

was successful.

6. You can access your new COM: port by using the assigned COM: identifier. This assignment will

vary from system to system.

7. To verify operation use Sealevel Systems supplied WinSSD diagnostic utility. WinSSD can be found

in the Start, Programs group.

The SeaLINK+8/232.RJ is now ready for use.

Technical Description

The SeaLINK+8/232.RJ utilizes eight USB UARTs. These chips feature programmable baud rate, data

format, 128 byte Dual Port TX Buffer, and 384 byte Dual Port RX Buffer. The transceivers support data rates

up to 921.6K bps.

Optional DC Power on Pin 5

The 2804 is USB bus powered, so no external power supply is required. For conveniently powering serial

peripherals, ordering options allow an external power source up to be connected to a DC jack on the rear of

the unit. The supplied power is connected to pin 5 on each of the eight RJ45 connectors. Each serial port

utilizes an auto-resetting fuse rated at 500mA. Ordering options are shown below:

•Item# 2804-DC05

Configured for 5VDC input power using a 2.1mm DC jack

•Item# 2804-DC12

Configured for 12VDC input power using a 1.3mm DC jack

•Item# 2804-DC24

Configured for 24VDC input power using a 1.3mm DC jack

Optional RJ45 to DB9 RS-232 Adapter

Preconfigured for use with Sealevel USB RJ45-enabled serial adapters, the RJ45 to DB9 modular adapter

(item# RJ9P-232) converts the RJ45 RS-232 pin out to a DB9 male RS-232 serial port. Standard CAT5 patch

cables can be used to extend the serial port up to 50 feet away from the RJ45 port. The pin out for the

RJ9P-232 is shown below.
