2. Overview

2.1 Introduction

The 4-Port RS-232 USB Hub has four (IC1027A) or eight (IC1023A) USB to RS-232

asynchronous serial ports that enable you to connect non-USB peripherals to a

USB bus. It doesn’t require installing cards, I/O ports, or IRQs. However, you must

have a recent enough operating system to support USB.

CHAPTER 3: Installation

3. Installation

3.1 Windows®

1. Users running Windows® 10 or later, proceed to section 3.2 Hardware installation.

Windows should automatically detect and load the correct drivers.

2. If Windows does not automatically detect and load the correct drivers, download the

SeaCom drivers from the Black Box® website.

4-PORT RS-232 USB HUB

3.2 Hardware Installation

1.Connect the RS-232 USB Hub to any upstream type “A” port either at the PC

host or an upstream hub. The hub is hot-pluggable, so you don’t have to

power down your computer before installing it.

2. The New Hardware Found wizard will now locate the appropriate drivers.

These drivers were installed during the software setup procedure. Once the

drivers are found, a new window will appear and tell you that the new ports

are installed properly.

3. If you view the system’s Device Manager, new COM ports in the Ports (COM

& LPT) device class should appear.

4. You can access your new COM ports by using the assigned COM identifiers as

shown in the Device Manager. The assigned COM port may differ from

system to system. The hardware is now recognized and ready to use.

Appendix A. Troubleshooting

A.1 Calling Black Box

If you determine that your RS-232 USB Hub is malfunctioning, do not attempt to

alter or repair the unit. It contains no user-serviceable parts. Contact Black Box

Technical Support at 1-877-877-2269.

Before you do, make a record of the history of the problem. We will be able to

provide more efficient and accurate assistance if you have a complete description,

including:

• the nature and duration of the problem.

• when the problem occurs.

• the components involved in the problem.

• any particular application that, when used, appears to create the problem or

make it worse.

A.2 Shipping and Packaging

If you need to transport or ship your RS-232 USB Hub:

• Package it carefully. We recommend that you use the original container.

• If you are returning the unit, make sure you include everything you received

with it. Before you ship for return or repair, contact Black Box to get a Return

Authorization (RA) number.

APPENDIX A: Troubleshooting

4-PORT RS-232 USB HUB

Appendix B. Electrical Interface

RS-232

Quite possibly the most widely used communication standard is RS-232. This

implementation has been defined and revised several times and is often referred to

as EIA/TIA-232. The IBM® AT® computer defined the RS-232 port on a DB9

connector and subsequently the EIA/TIA approved this implementation as the

EIA/TIA-574 standard. This standard is defined as the 9-Position Non-Synchronous

Interface between Data Terminal Equipment and Data Circuit-Terminating

Equipment Employing Serial Binary Data Interchange. Both implementations are

in widespread use and are referred to as RS-232 in this document. RS-232 is

capable of operating at data rates up to 20 kbps at distances less than 50 feet

(15.2 m). The absolute maximum data rate may vary due to line conditions and

cable lengths. RS-232 is a single-ended or unbalanced interface, meaning that a

single electrical signal is compared to a common signal (ground) to determine

binary logic states. The RS-232 and the EIA/TIA-574 specification define two types

of interface circuits, Data Terminal Equipment (DTE) and Data Circuit-

Terminating Equipment (DCE). The RS-232 USB Hub is a DTE device.

Appendix C. Asynchronous

Communication

Serial data communications implies that individual bits of a character are

transmitted consecutively to a receiver that assembles the bits back into a character.

Data rate, error checking, handshaking, and character framing (start/stop bits) are

pre-defined and must correspond at both the transmitting and receiving ends.

Asynchronous communication is the standard means of serial data communication

for PC and compatible computers. The original PC was equipped with a

communication or COM port that was designed around an 8250 Universal

Asynchronous Receiver Transmitter (UART), which allows asynchronous serial

data to be transferred through a simple and straightforward programming device.

Asynchronous communication works this way: A start bit, followed by a pre-defined

number of data bits (5, 6, 7, or 8) defines character boundaries for asynchronous

communication. The end of the character is defined by the transmission of a pre-

defined number of stop bits (usually 1, 1.5, or 2).

Figure C-1. Asynchronous communication bit diagram.

An extra bit used for error detection is often appended before the stop bits. This

special bit is called the parity bit. Parity is a simple way to determine if a data bit

has been lost or corrupted during transmission. There are several methods for

implementing a parity check to guard against data corruption. Common methods

are called (E)ven Parity or (O)dd Parity. Sometimes parity is not used to detect

errors on the data stream (this is called [N]o Parity). Because each bit in

asynchronous communication is sent consecutively, it is wrapped (framed) by pre-

defined bits to mark the beginning and end of the serial transmission of the

character. The data rate and communication parameters for asynchronous

communication have to be the same at both the transmitting and receiving ends.

The communication parameters are baud rate, parity, number of data bits per

character, and stop bits—for example, 9600, N, 8, 1.
