BMUSB RS232 User’s Manual

Introduction The BaudMasterTM 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 BaudMasterTM 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. Selfpowered 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.

Description

The diagrams below show the function blocks, signal paths and isolation of the BaudMasterTM USB-to-RS232 converters.

BaudMaster

BMUSB RS232 User’s Manual

Isolated BaudMasterTM 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.
