Chapter 2: Overview

2. Overview

2.1 Introduction

The USB to Multi RS-232/422/485 Interface Converter (IC292A) provides an easy

way to connect up to four DB9 serial devices to a single USB port. All

configuration and electrical interface selections are handled through the driver, so

you don’t have to open the enclosure to set jumpers or switches. The serial port is

software configurable for RS-232, RS-422, or RS-485 (full- and half-duplex).

The IC293A software drivers and utilities make installation and operation easy for

Windows®98SE, ME, 2000, XP, and Windows Vista®operating systems. Once the

software is installed, plug the interface converter into an available USB port. Each

serial port is recognized as a standard COM port by the host system enabling

compatibility with legacy software. Serial data rates to 921.6 kbps are supported.

To prevent accidental cable disconnection, the interface converter integrates a

patent-pending high-retention locking USB port that is fully compatible with

standard USB cables. When used with the included USB cable with a high-

retention USB type B connector, the metal thumbscrew provides a secure

connection to the device. Standard operating temperature range is 32 to 158° F

(0 to 70° C) and extended temperature range is -4 to +185° F (-40° C to +85°

C). Status LEDs display electrical interface selection and serial data activity for each

port.

2.2 Features

• Each port is individually software configurable for RS-232, RS-422, and two-wire

or four-wire RS-485.

• Maintains electrical interface settings across multiple computers.

• Includes high-speed UART with 128-byte Tx FIFO and 384-byte Rx FIFO.

• Automatically enables/disables hardware RS-485.

• DB9M connector serial port supports data rates to 921.6 kbps.

• Powered by USB host connection.

• Implements full modem control signals in RS-232 mode.

• Status LEDs indicate power, electrical interface, and serial data activity for each

port.

Chapter 2: Overview

2.3 What’s Included

The interface converter ships with the following items. If any of these items is

missing or damaged, contact Black Box Technical Support at 724-746-5500 or

info@blackbox.com.

• USB to RS-232/422/485 Interface Converter, 4-Port

• (1) 6-ft. (1.8-m) USB Type A to high-retention USB Type B cable

• Software and this user’s manual on CD-ROM

2.4 Optional Items You May Need

Depending upon your application, you might also need the following items.

Contact Black Box Technical Support at 724-746-5500 or info@blackbox.com

for details.

Cables:

• DB9F to DB25M (RS-232) Extension Cable (BC03000-0006-MF)

The BC03000-0006-MF 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 long.

• DB9F to DB9M Extension Cable (BC00200)

The BC00200 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.

Terminal blocks:

The IC981 terminal block breaks out a DB9 connector to nine screw terminals to

simplify field wiring of serial connections including RS-422 and RS-485 networks.

The IC981 is designed to connect directly to Sealevel DB9 serial cards or any cable

with a DB9M connector.

Adapters and Converters:

The FA756 is a DB9 female to RJ-45 adapter. It can be configured without tools,

and it is an excellent choice for using available infrastructure wiring.
