3. Transport and storage
Care should be taken to properly protect the devices so as to eliminate any damage during transport. It is forbidden to
transport the devices in a collective package without adequate amortisation - each device must be packed
separately and cannot have freedom of movement during transportation.
Due to the protective packing the module should be stored in the temperature not lower than -  

4.3.2 Roof as a stand of the device
The appropriately mounted roof may function as a stand. The standard configuration of the mounting bracket
functions as a roof, but after its relocation, it may also serve as a stand with an adjustable angle (Fig. 4).
Fig. 4
5. Mounting the device
Correct mounting consists in installing the device on a flat surface or by using the roof as a stand (Fig. 4). Only
the proper mounting of the device ensures its proper operation and the maintenance of the device parameters,
like, among others, the housing tightness rating to satisfy the IP code.
NOTICE!
Before any installation or maintenance operations refer to the manual supplied by the manufacturer. Improper
connection to the mains power supply, incautious device installation, or improper use may cause the property
damage, loss of health or death from electrical shock! In addition, any failure to follow the manufacturer's
instructions may void your warranty.
NOTICE!
It is forbidden to make any additional mounting points or any holes in the device assembly components.

5.1 WA-2 Professional device
The device is designed to display the measurement results transmitted by weighing terminals. For the proper
operation of the device, it is necessary to pre-configure it using the RGB WagSet 2 software available at
RGBtechnology.pl/soft or through the user menu embedded in the device.
5.2 WA-2 Professional configuration
The configuration of the device using RGB WagSet 2 enables:
1) Precise defining the communication protocol with any weighing terminal,
2) Defining the reaction to the events reported by the weighing terminal (eg. overloading, underloading,
instability, etc.),
3) Entering advertising text.
5.2.1 Defining communication protocols
5.2.1.1 Embedded user menu (micro switch)
The user menu embedded in the device allows you to select the communication protocol, display the information
about the software version, reset the device to the default settings. The micro switch, used to operate the menu, is
located inside the display housing, however, after unscrewing the lock screw (fig. 5, det. A) micro switch is
available through the thru-hole (fig. 5, det. B) without opening the device.
det. A lock screw; det. B thru-hole
rys. 5
The user menu is called up by pressing and holding the "DEF" micro switch and releasing it when the desired
option is displayed. Regardless of the option, you can exit the user menu by pressing the micro switch and
releasing it when switching between the options (when switching between the options, the display does not
display any information)
The user menu has the following options:
1) info This option enables displaying the software version. For the displays with the Ethernet interface,
additionally the network layer settings are given (the IP address, the network mask, the communication
port for the RGB WagSet 2 program, and the communication port for the weighing terminal). The info
option is exited automatically after displaying information.
2) proto This option allows you to select the display communication protocol for the cooperation with the
weighing terminals pre-loaded into the device memory . The amendments to the protocol are introduced
by pressing the micro switch. You can approve the protocol by holding the micro switch for a long time
(until the inscription "Saved" appears). The "proto" option is left after 30 seconds of the user inactivity.
3) custm The "custm" option allows you to choose a dedicated display communication protocol for the
cooperation with the weighing terminals of the selected customers. The protocols have special nonstandard
settings meeting the needs of a given customer. Setting the protocol is done in the same way as for the
"proto" option you can approve the selected protocol by holding the micro switch for a long time (until
the inscription "Saved" appears), while leaving the "custm" option is done automatically after 30 seconds of
the user inactivity.

6 DTR_304-02-01-003_EN_a
4) reset This option allows you to restore the default protocol of the display for weighing scales. In addition, in
the devices with the Ethernet interface, it allows you to restore the default settings of the network layer (IP
address: 192.168.0.11, network mask: 255.255.255.0, communication port for the WagSet2 software: 2102,
and the communication port for the weighing terminal). To restore the default settings, you should, during
the normal operation of the device, press the micro switch and hold it until you see the inscription "reset".
Hold the micro switch until the inscription "reset" starts blinking and do not release it until you see the
inscription "default". Releasing the switch before displaying the inscription "default" will stop restoring the
default settings and the display will continue to operate with the previously set parameters. Uploading new
network settings is possible only by using the RGB WagSet 2 software available at RGBtechnology.pl/soft.

5.2.1.3 RGB WagSet 2 software
Using the WagSet 2 software, you can perform the advanced configuration of the device. The program allows you
to change, among others: the parameters of displaying the weighing result, entering and editing advertising text,
the display response to special situations such as: exceeded measurement range, etc. The detailed information
on the configuration from your computer can be found in the manual supplied with the RGB WagSet 2 program.
6. Weighing scale controller
The weighing scale controller is a device responsible for displaying the measurement result transmitted by the
weighing terminal.

Table 2 presents the description of the WEIGHING SCALES controller connectors (Fig. 8, det. B) in the WA-2
Professional display for weighing scales. The connectors are accessible after the disassembly of the back cover
(Fig. 8, det. C) by removing the front of the device (Fig. 8, det. A). Moreover, on the back cover, LED modules are
also fixed (Fig. 8, det. D).

7. Automatic brightness control of the display for weighing scales
7.1 Lighting sensor
In the standard version, the display for weighing scales has a lighting sensor included, which is placed on the LED
panel. The device, in response to the intensity of daylight, adjusts the brightness of the display for weighing
scales.
4On the PCB controller there are located all connectors available as standard, however, only the RS-232 interface cable (without a tip) is
led out.

8. Initial start-up
Step 1: Make sure that all cables are properly connected,
Step 2: Make sure that all components have been installed in the correct orientation,
Step 3: Connect the device to the mains power source,
Step 4: If properly connected, the system will display moving arrows (<<<<), followed by the symbol of a hard
space (_) shown in the bottom right corner, which means that the user has 7 seconds to send the
configuration to the display for weighing scales. If the user does not enter the configuration, the display
for weighing scales will start running a demo, that is, a moving text (user text).
9. Additional options
9.1 Temperature probe
The temperature probe (Fig. 8) is available with two versions of a signal cable length 0.5m and 2m.
The probe enables measuring and displaying temperature only in . The detailed description of the
