Introduction

Overview

The SeaLINK® 2401 USB serial I/O adapter equips the PC with four RS-232 asynchronous serial ports for

USB connectivity to legacy or non-USB compliant devices. 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.

Sealevel SeaCOM USB software drivers and utilities make installation and operation easy using Microsoft

Windows and Linux operating systems. After installing the software, simply connect the 2401 serial

interface adapter to your USB port. The device and serial ports are immediately recognized as standard

COM ports by the host system enabling compatibility with legacy software. Now your non-USB peripherals

can have the same connection simplicity and ease of use as USB aware peripherals.

Features

•Compliant with RoHS and WEEE directives

•High-speed UART with 128-byte Tx FIFO and 384-byte Rx FIFO

•Data rates from 300 bps to 460.8 Kbps

•All modem control signals implemented

•Serial and USB activity LEDs

•Hot-swappable

•Powered by USB connection

•Sealevel SeaCOM software supports Microsoft Windows and Linux operating systems

•DB9M connectors

•Includes 6’ USB device cable (Item# CA179)

Before You Get Started

What’s Included

The SeaLINK +4/232 (2401) is shipped with the following items. If any of these items are missing or

Advisory Conventions

Warning

The highest level of importance used to stress a condition where damage could result to the

product, or the user could suffer serious injury.

Important

The middle level of importance used to highlight information that might not seem obvious or a

situation that could cause the product to fail.

Note

The lowest level of importance used to provide background information, additional tips, or other

non-critical facts that will not affect the use of the product.

Optional Items

Depending upon your application, you are likely to find one or more of the following items useful. All items

can be purchased from our website (www.sealevel.com)by calling our sales team at (864) 843-4343.

Cables

DB9F to DB25M (RS-232) Modem Cable (Part# CA177)

The CA177 is a standard AT-style RS-232 modem cable

with a DB9F connector on one end and a DB25M

connector on the other. This cable is 72 inches in length.

DB9F to DB9M Extension Cable (Part# CA127)

The CA127 allows users to extend a DB9 cable up to six

feet. The connectors are pinned one-to-one, so the cable

is compatible with any device or cable that has DB9

connectors.

DB9 Female to 9 Screw Terminal (Part# TB05)

The TB05 terminal block breaks out a DB9 connector to

9 screw terminals to simplify field wiring of serial

connections. It is ideal for RS-422 and RS-485 networks,

yet it will work with any DB9 serial connection, including

RS-232. The TB05 includes holes for board or panel

mounting. The TB05 is designed to connect directly to

Sealevel DB9 serial cards or any cable with a DB9M

connector.

OPTIONAL ITEMS, CONTINUED

Hubs

High Speed 4-Port USB 2.0 Hub with SeaLATCH USB Ports (Part# HUB4PH)

The hub is USB 2.0 compliant, providing a full 480M bps

data rate to the host, and is backwards compatible with

USB 1.1 and 1.0 devices. The HUB4PH includes a wall-

mount AC adapter that supplies a full 500mA to each

attached USB peripheral. The power supply outputs 5VDC

@ 2.4A and has a locking DC connector to prevent

accidental removal of the power cable.

High Speed 7-Port USB 2.0 Hub (Part# HUB7P)

The HUB7P is USB 2.0 compliant, providing a full 480M

bps data rate to the host, and is backwards compatible

with USB 1.1 and 1.0 devices. The powered hub includes

a wall-mount AC adapter that supplies a full 500mA to

each attached USB peripheral. The power supply outputs

5VDC @ 4A and has a locking DC connector to prevent

accidental removal of the power cable. The hub is housed

in a rugged plastic enclosure and status LEDs indicate

external power, connection to the host, and fault

conditions.

Adapters and Converters

DB9F to RJ45 Modular Adapter (Item# RJ9S8)

The RJ9S8 is a DB9 female to RJ45 adapter. It can be

configured without tools and is an excellent choice for

using available infrastructure wiring.

DB9 Female to DB9 Male - Serial Surge Suppressor (Part# SS-DB9)

User configurable for use with male or female DB9 ports,

the SS-DB9 protects all 9 lines, plus D shell chassis.

Convenient DB9 input and output connects directly to the

protected port, obtaining a ground outlet from the

computer chassis. Surge suppression is handled with

balanced arrays of high-speed avalanche diodes that

divert excess energies created by electrostatic

discharges, faulty wiring, or lightning away from network

interface connections.

Product Family

Whether you require one serial port or 16, SeaLINK USB serial adapters will have you quickly communicating

with RS-232, RS-422, and RS-485 peripherals. Unlike traditional UART-based devices, SeaLINK USB

products use a state-machine architecture that reduces host processor overhead for faster, more reliable

communications. Sealevel's SeaCOM software drivers and utilities make installation and operation easy

using Microsoft Windows and Linux operating systems.

Please terminate any control signals that are not going to be used. The most common way to do

this is connect RTS to CTS and RI. Also, connect DCD to DTR and DSR. Terminating these pins, if

not used, will help insure you get the best performance from your adapter.
