USB to 2-Wire RS-485 Converter

Galvanically Isolated,

DIN Rail Mounted

620-0019 R2 © Microﬂex 2016-2021

General Description

The 101-0019 USB to RS-485 converter provides a simple, interface between

a PC or laptop computer with a USB port and 2-wire RS-485 devices. Virtual

serial port Universal Serial Bus (USB) drivers make this converter compable

with most soware developed for RS-232 communicaons serial port interfaces

because it appears as an RS-232 port to your soware. Switching between

receive and transmit is automacally controlled, so RTS (Request To Send) is not

needed - maximizing soware compability. Power for the converter is taken

from the USB port eliminang the need for an external converter power supply.

It includes high ESD protecon (±15kV HBM) on transceiver, high common

mode transient immunity (30kV/s), plus 2500VRMS transformer isolaon

between the line transceiver and USB logic. Ideal for systems where the ground

loop may be broken allowing for large common mode voltage variaon.

DIN rail mounng allows the converter to be quickly installed in your equipment

rack, along with other DIN mounted equipment.

Driver Pre-Installation

The USB drivers should be installed before the RS-485 converter is connected to

the PC’s USB port. Aer the drivers are installed, Windows will automacally

detect the converter when it is connected to a USB port and complete the

setup.

To pre-install the drivers, run

Setup.exe from the included CD and

follow the on-screen prompts. The CD

will auto-run this ﬁle if the Windows

Autorun feature is enabled for your

CD drive. Setup.exe is a ulity that

will determine your operang system

and run the correct installer. Click the

Install RS-485 Converter USB drivers...

buon to pre-install the drivers. The

driver installer will guide you through

the setup process.

Installers can also be run manually from the CD using \x86\DPInstx86.exe for 32

bit operang systems or x\64\DPInstx64.exe for 64 bit operang systems.

RS-485 Convert Setup Utility

Install USB driver before

connecƟng to the USB port.

Important!

Driver - Manually Installed

To manually install the driver...

1. Connect the Converter to the USB port.

2. Open the Windows Device Manager.

3. The new device wizard will have added the converter under Ports (COM &

LPT) and will appear as USB RS485 Serial Converter (COMx). Right click the

device and select Update Driver Software...

4. Choose to Browse for the driver soware and browse to the CD or the

locaon of the Mﬂex485.inf ﬁle.

5. Follow the wizard prompts to complete the driver setup.

Finding the Assigned COM Port Number

When Windows installed the serial port emulator driver the next available COM

port number was assigned to the converter. The soware you use with the

converter must be set to use the same COM port number. To ﬁnd the number

assigned to your converter run the setup ulity from the CD and click

Find my Converter’s COM port number...

The assigned COM port number can also be found using the Windows Device

Manager. You may need to expand the Device Manager tree under

Ports (COM and LPT) to see the converter.

Uninstalling the USB Driver

Use the Windows Device Manager to uninstall the driver from your system.

With the RS-485 Converter connected to your USB port, locate the RS-485

converter in the hardware tree. For details on how to do this refer to the

secon on Changing the COM Port Number in this manual. Right click on USB

RS485 Serial Converter and select Uninstall from the pop-up menu. When the

process has ﬁnished, unplug the converter from the USB port.

COM Port number ﬁnder. This converter is assigned to COM 3.

Changing the COM Port Number

The assigned serial COM port number can be changed to any available COM

port by using the Device Manager. Open the Device Manager and select

View > Devices by Type. Expand Ports (COM & LPT) in the list to see which port

the converter is assigned to. In the example shown below, the converter is

assigned to COM3.

Right click on USB RS485 Serial Converter and select Properties from the pop-up

menu.

On the Port Settings tab, click Advanced. Drop down the COM Port Number list

and select the desired port number. Click OK to use the new port number and

close the window.

Click OK again to close the Properes window.

Windows Device Manager.

Software Setup

Make sure your soware is set to use the same serial COM port that the

RS-485 converter was assigned to. Refer to Finding the Assigned COM Port

Number and Changing the COM Port Number in this manual for details. There

are no hardware sengs required by the RS-485 Converter and power is

provided by the USB port. All other sengs, such as BAUD rate, are taken care

of by your soware. The converter automacally switches between transmit

and receive so RTS is not required.

DIN Rail Mounting

The converter is designed to mount on standard 35mm DIN rail. It can be easily

snapped on and othe DIN rail without the need for any tools.

Liup on the release lever to unsnap the converter from the rail.

Connecting to the RS-485 Bus

Connect the converter to the RS-485 bus using the A, B, and Gscrew

terminals. Connect the Gterminal to the RS-485 bus ground or shield. The G

ground is galvanically isolated from the converters USB ground. Aand Bare the

non-inverng and inverng RS-485 transceivers.

The converter does not include an internal bus terminang resister.

RS-485 busses typically require a terminang resister at each end of the bus.

Connecng directly to a device, to perform a conﬁguraon for example, may be

done without a terminang resistor.

Status LED

When the converter is connected to a USB port the LED will be green aer the

USB enumeraon process completes and the USB drivers have successfully

inialized. A green LED indicates that the converter is ready to receive or is

receiving.

The LED will be red while the converter is transming RS-485 data.
