Introduction

The BaudMaster

TM

BMUSB family of converters are

designed to allow the connection of RS-232 devices to

any USB equipped PC. Each converter functions as an

USB-to-UART bridge with an isolated or non-isolated

RS-232 interface. The isolated BaudMaster

TM

converters provide protection from voltage spikes and

ground loops that may hamper communications or harm

computer ports.

Features

USB-to-UART Bridge USB Specification 2.0

compliant; backward compatible with USB 1.0 and 1.1

Virtual COM Port Windows will install the

converter as an additional COM port that is compatible

with existing COM Port PC applications. Drivers are

supplied for Microsoft Windows ® XP, Windows ®

2000 and Windows ® 98SE.

Direct USB Device Support Alternative drivers are available that provide an alternative

interface solution that does not implement a COM port. A simple, high-level application program

interface (API) is used to provide simpler USB-UART connectivity and functionality.

Status LEDs Status LEDs are provided for USB Suspend, Transmit, and Receive signals. Self-

powered models also have a Power LED. These are handy for verifying operation and

troubleshooting network problems.

Electrical Isolation Isolated converter models use optical and transformer isolation technology

to provide up to 2000 volts of signal and ground isolation between the computer and equipment.

Eliminates ground loops that destroy computer ports and reduce serial communications

reliability.

Transient Voltage Protection All signal and power lines are protected against transient

voltages.

Versatile Power Supply The unit can be powered by a wide range of AC or DC voltages.

Wall-plug adapters are available from duTec or others. A pluggable screw terminal is also

provided for use with other power supplies.

Pluggable Terminal Blocks Industrial rated pluggable terminal blocks for ease of installation

or removal. Accepts up to 16 AWG wire.

DIN Rail Mounting DIN Rail mounting accessories available for easy wiring.

BMUSB RS232 User’s Manual

Isolated BaudMaster

TM

BMUSB converters provide full galvanic isolation from RS232-to-USB

and RS232-to-Power using optical and transformer technology. Galvanic isolation breaks the

signal, power and ground paths using transformer and optical technology. Data is allowed to

flow between systems but not electrical current, eliminating grounding problems. All

communication and power lines are transient protected.
