Universal Serial Bus (USB) has become the

connectivity workhorse of today’s PCs, replacing the

familiar serial ports. However, many commercial

and industrial devices still use the RS-485 interface.

To connect these devices to modern PCs, you need

a simple and reliable conversion solution. The

IC832A and IC833A offer this solution in a space

saving, USB Port powered package. Simply plug

the converter into an available USB port on your

computer or USB hub and install the drivers

supplied on CD ROM. The device will show up as

an additional COM port in the Windows Device

Manager which is fully compatible with your

Windows applications. A one meter USB cable is

included. 

Check Drivers

Screen shots are from Windows XP

•Right click on My Computer. Select the Hardware

tab.

•Expand the USB Controllers tree. The USB Serial

Converter will be listed.

•Expand the Ports (COM & LPT) tree. The USB

Serial Port will be listed as the next available

COM Port.

Installation Notes

•

When the driver is installed, the converter is associated

to that PC. If you plug in a different converter, the driver

must be installed again. Another COM port will also be

created with the driver installation.

•Instructions for uninstalling the driver are located on the

CD ROM.

IC832A Wiring

•

This converter is used for RS-485 2-Wire Systems.

•Loosen the screws to open the Terminal Block lead

clamps for the A(-), B(+), and GND terminals.

•Insert the RS-485 2-Wire signal leads in accordance

with the diagram above. The TB will accept 28 to 16

AWG wire.

•Tighten the screws to close the TB lead clamps. Ensure

the clamps hold the leads securely. However, do not

over tighten.

•Bias is provided by 4.7KΩpull-up and pull-down

resistors.

•If termination is required, it must be installed externally.

In most cases, termination is not required.

•During operation, the receiver toggles with the transmit

data.

485USBTB-4W Wiring IC832A Loop Back Test

IC832A Back to Back

Test

•

Loopback TDA(-) to RDA(-) and TDB(+) to

RDB(+) as shown in the diagram above.

•Using Hyper Terminal or similar program,

connect to the appropriate COM port. Set the

desired baud rate. Ensure Hyper Terminal local

echo is OFF.

•Transmit data. If the same character string is

returned, the test is good.

•This converter is used for RS-485 4-Wire Systems.

•Loosen the screws to open the Terminal Block lead

clamps for the TDA(-), TDB(+), RDA(-), RDB(+), and

GND terminals.

•Insert the RS-485 2-Wire signal leads in accordance

with the diagram above. The TB will accept 28 to 16

AWG wire.

•Tighten the screws to close the TB lead clamps. Ensure

the clamps hold the leads securely. However, do not

over tighten.

•Bias is provided by 4.7KΩpull-up and pull-down

resistors.

•If termination is required, it must be installed externally.

In most cases, termination is not required.

•During operation, the receiver is always active.

•

Due to the circuit configuration, a loop back test

is not possible with this model. However, two

converters can be used in a back to back

configuration.

•Wire the converters as shown above.

•Using Hyper Terminal or similar program,

connect to the appropriate COM ports. Set the

desired baud rate.

•Transmit data. If the same string is received on

the distant end, the test is good.
