CHAPTER 2: Introduction

2. Introduction

Connect old-style serial peripherals (modems, serial

printers, etc.) to the USB port on your Windows

computer. The USB Solo (USB→Serial) converts the

USB interface to a standard RS-232 serial interface with

an ordinary DB25 or DB9 connector.

2.1 How Does USB Work?

USB uses a unique cable and connector system. The

“upstream” side of the cable (“A” side) connects to

a USB hub or PC. The “downstream” side (“B” side)

connects to USB devices or to another hub’s “A” side.

The USB Solo has a “B” side connector on one side and

a legacy COM or RS-232 port connector (DB25 or DB9)

on the other side. It allows you to plug a legacy COM-

port device (such as a modem, digital assistant, or

printer) into the USB bus.

Two models are available: The IC138A-R2 has a DB25 on

the RS-232 side, and the IC199A has a DB9 connector

on the RS-232 side.
