4.1. DESCRIPTION OF SIGNALLING LEDS 

LED

Description

PWR

Signalling of Power Supply

Normal Operating

RX

Signalling of data receiving through ADA-4010A converter from RS232 port.

TX

Signalling of data transmitting from ADA-4010A converter through RS232 port.

Configuration

LED by SW1 Blink with frequency1 Hz - signalling of configuration mode (see micro-switch SW1 setting).

Software updating

LED by SW1 Blinking - signalling data flow of software to converter.

ATTENTION!

At baud rate above 38.4 kbps the LED's Tx, Rx will light weakly during  data transmission 

4.2. TROUBLESHOOTING

Problem

Solutions

PWR led not light

Check polarization and parameters of connected power supply.

Tx led light continuously

RS485(4W) / RS422 bus. Wrong polarization on  Rx+, Rx- terminals. Change polarization 

RS485(2W) bus. Wrong polarization on Tx+/A, Tx-/B  terminals. Change polarization 

No transmission,

Tx led blinking.

RS485(4W)   /   RS422   bus.   Check   connection     correctness   of   Tx,  Rx  terminals   according   to

chapter 3.

5. CONFIGURATION 

5.1. CONVERTERS OPERATION MODE 

ADA-4010A converter can operate in few modes as:

run,

configuration,

factory default,

emergency firmware update

Those modes can be set by use SW1 located by terminal block  RS455/RS422. To set the switch section, should  remove terminal

cover marked as SW1 and make the appropriate settings by the use a small, flat screwdriver. 

All available adjusting the SW1 switch are shown in table below.

Operation modes

Factory default

Turning OFF and ON the power of the converter, the configuration will be set

to factory default.

ON

Emergency Firmware Update

5.2. CONFIGURATION BY THE USE OF ADACONFIG

The configuration of ADA-4010A converter should be done by use of 

ADAConfig

 software - selling with converter. 

To make the configuration, connect converter to computer (see pt. CONNECTION TO PC) and power supply. If after power, on the

front panel is not lit green LED PWR, check the power connection (polarity). If the PWR LED lights, set the section of SW1 switch to

configuration mode as in table below.

SW1-1

SW1-2

ON

OFF

In the configuration mode the yellow LED located by SW1 micro-switch will blink with frequency 1 Hz. Start the ADAConfig software

and make the configuration of transmission parameters for each interfaces and set his visible address from RS485 bus. Firstly should

be set a number of COM port for communication with the converter, then readout the configuration from converter's memory using the

button 

[Read converter configuration]

 and make the proper changes of interfaces setting.

5.2.1. CONFIGURATION OF ADDRESSING MODE

If the option Converter Address will be enabled, on configuration window should be set a proper converter address from range 1 - 255.
If this option is disabled the converter will operate as 

baud rate converter
