4.1 WA- 1 Optima application
The devices of the WA series are designed to display measurement results transmitted by weighing terminals.
The displays operate in the automatic mode by default (see Autolearn) and in typical cases do not require prior
configuration. In special situations, it may be necessary to adjust the settings by means of the RGB WagSet 2
software or through the user menu embedded in the device.
4.2 Autolearn function
The Autolearn mode is enabled by default (position no. 0 is set in the 'proto' submenu). In order to disable it,
the communication protocol must be set manually using the embedded user menu or the RGB WagSet 2
software.
When this mode is active, each time the device is started, it detects the parameters of the communication with
the weighing terminal and analyses the structure of the data frames it sends. Then it adjusts the remote
display's settings to enable correct communication with the terminal. The whole operation lasts several
seconds, depending on the baud rate and the time intervals between consecutive frames. All remote display’s
communication interfaces are supported, i.e. RS232/RS485/CL and the Ethernet (optional interface)4.
The Autolearn procedure is as follows:
1. Baud rate detection - dot 1 flashing on the display
2. Baud rate verification - dot 1 solid, dot 2 flashing
3. Analysis of the protocol and its frame structure - dots 1 and 2 solid, dot 3 flashing
During the analysis of the protocol and its frame structure, the measurement unit sent is also recognised. The
following tags are recognised - "kg" 'K' " t" 'T' 't' " g" "gr" 'G' 'g' "lb" 'L' 'l' "oz" 'o' 'O'. In case the terminal does
not send a unit or sends a unit that is not recognised by the Autolearn function, the default unit will be set.
Depending on the purchased regional version, it is "kg" or "lb".
The Autolearn mode supports the following transmission parameters:
Baud rate:
2400, 4800, 9600, 19200
Transmission parameters (data bits,
parity, stop bits):
8N1, 7E1, 7O1
4.3 WA-1 Optima manual configuration
The configuration of the device using RGB WagSet 2 allows:
1Precise defining of the communication protocol with any weighing terminal;
2Determining the response to the events reported by the weighing terminal (e.g. overloading,
underloading, instability, etc.);
3Entering advertising text;
4.3.1 Defining communication protocols
4.3.1.1 Embedded user menu ( "DEF" microbutton)
The user menu embedded in the device allows you to select a communication protocol, display the information
about the software version, reset to the default settings. The "DEF" microbutton, used to operate the menu, is
located inside the display. However, after unscrewing the lock screw (Fig. 4, det. A), it is accessible through a
technological hole (Fig. 4, det. B) without opening the device. The button is at a depth of approx. 30mm.
4If first the data is sent via the Ethernet to the display and then one of the other interfaces, i.e. RS232 / RS485 / CL is connected - the Autolearn procedure will be carried out again in order to determine the UART parameters and the protocol (the
protocol for serial interfaces may differ from the Ethernet protocol).

Fig. 4
The user menu is called up by pressing and holding down the "DEF" microbutton and releasing it when the
desired option is displayed. Regardless the option, you can exit the user menu by pressing the microbutton and
releasing it when switching between the options (while switching between the options, the display is not
displaying any information)
The user menu has the following options:
1) info - This option allows you to display the device software version. For the displays with the Ethernet interface,
the network layer settings are additionally provided (an IP address, a network mask, a communication port for
the RGB WagSet 2 software and a communication port for the weighing terminal). Exiting the info option
happens automatically after displaying the information.
2) proto - This option allows you to select the display communication protocol to work with the selected
weighing terminals (Tab. 1). You can change the protocol by short pressing the microbutton. Saving the
selected protocol is accomplished by long holding down the microbutton (until the message "Saved"
appears). Exiting the "proto" option happens automatically after 30 seconds of user inactivity.
3) custm - The "custm" option allows you to select the display communication protocol to work with the
weighing terminals of the selected clients. These protocols have special, custom settings needed for the
given client. Setting the protocol is done in the same way as in the case of the "proto" option - saving the
selected protocol is accomplished by long holding down the microbutton (until the message "Saved"
appears), while exiting the "custm" option happens automatically after 30 seconds of user inactivity.
4) reset - This option allows you to restore the default settings of the remote display and to activate the
Autolearn mode. In addition, in the devices with the Ethernet interface, you can restore the default
network layer settings (IP address: 192.168.0.11, network mask: 255.255.255.0, configuration port for the
RGB WagSet 2 software: 2101, communication port for the weighing terminal: 2102). To restore the default
settings you should, during the normal operation of the device, press the microbutton and hold it down
until the message "reset" appears. Hold the button down until the message "reset" starts flashing and do
not release it until the message "default" is displayed. Releasing the button before the message "default"
appears will result in interrupting the process of restoring the default settings and the display will continue
working according to the previously set parameters. Uploading new network settings is only possible using
the RGB WagSet 2 software available at www.kazel-displays.com
