4.1. DESCRIPTION OF SIGNALLING LEDS 

LED

Description

PWR

Signalling of Power Supply

RX

Signalling of data receiving through ADA-4040PC1 from RTU RS485/RS422 port

TX

Signalling of data transmitting from ADA-4040PC1 through RTU RS485/RS422 port

Yellow LED by 

SW1

Not light – signalling of normal operating mode (RUN)

Blinking at frequency 1 Hz - signalling of configuration mode or data flow of software to the converter.

Blinking at frequency 2 Hz - signalling of factory default mode

Lit continuously – signalling of emergency firmware update

4.2. TROUBLESHOOTING

Problem

Solutions

PWR LED is not light

Check polarization and parameters of connected power supply.

Rx LED lights continuously RS485(4W) /422 network. Wrong polarization on terminals: Rx+, Rx-; change polarization.

No transmission

Tx LED is blinking

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

according to point 3 and the converter configuration.

5. CONFIGURATION

5.1. OPERATION MODE

The ADA-4040PC1 converter can operates in a few modes :

RUN,

configuration,

factory default

emergency firmware update mode,

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

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

Figure 1 present the location of two-position SW1 micro-switch. All available adjusting the SW1 switch are shown in table below.

5.2. CONFIGURATION BY USING ADACONFIG

The configuration of ADA-4040PC1 converter can be made by the use of 

ADAConfig

 Software - selling with converter.

To make the configuration, connect converter to computer (see pt. 3.2) 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 converter interfaces. First should be set the number of COM port for

communication with the converter, then readout the configuration from ADA-4040PC1 memory using the button  

[Read converter

configuration]

 and make the proper changes of each interfaces setting, as below:

– baud rate (kbps): 0.3, 0.6, 1.2, 1.8, 2.4, 4.8, 7.2, 9.6, 14.4, 19.2, 28.8, 38.4, 57.6, 76.8, 115.2, 230.4,
– number of data bites: 5, 6, 7, 8,
– control parity: no control, parity control, control of none parity,
– number of stop bits : 1, 2,
– frame spacing – range from 1 to 255 (time silence as frame's end),
After configuration, the setting should be saved on converter memory by using button 

[Write converter configuration].

Return to work in run mode is made by using SW1 switch as below. The yellow LED (located near the SW1), will turn off.
