4.1. DESCRIPTION OF SIGNALLING LEDS
LED
Description
PWR
Signalling of Power Supply
RX
Signalling of data receiving through ADA-1040PC3 from RS485/RS422 port – MODBUS-RTU
TX
Signalling of data transmitting from ADA-1040PC3 through RS485/RS422 port – MODBUS-RTU
Yellow LED by
SW1
Not light – signalling of normal operating mode (RUN)
Blinking at frequency 1 Hz - signalling of configuration mode or software data flowing 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-1040PC3 converter can operates in a few modes :
–
run,
–
configuration,
–
factory default,
–
emergency firmware update
Those modes can be set by use SW1 located by DB-9F connector, labelled as RS232. To set the switch section, should remove the
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.

5.2. CONFIGURATION BY USING ADACONFIG
The configuration of ADA-1040PC3 converter can be made by the use of
ADAConfig
Software - selling with converter.
To make the configuration, connect converter to computer 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 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-1040PC3 memory using the button
[Read converter
configuration]
and make the proper changes of each interfaces setting, as below:
– setting of the converter address from the side of RS485 MODBUS-RTU bus - in group [
Converter Address
] select field [
Enable
]
and enter address MODBUS-RTU in field [
Address
] (scope 1-247),
– setting of address SunMaster inverter, connected to RS232 port, field [
Mapped address
] (scope 16-65535),
If SunMaster inverter address is known, in group [
Converter Address
] select field [
Address mapping
] and enter address of
SunMaster inverter in the field [
Mapped address
].
If SunMaster inverter address is unknown, in group [
Converter Address
] unselect field [
Address mapping
] and in the field [
Mapped
address
] don't enter any data.
– 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 4 to 255 (time silence as frame's end),
– data flow control – not available yet.
After configuration, the setting should be saved on converter memory by using button
[Write converter configuration].
