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)

.
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

WA-1 MINI manual configuration
The configuration of the device using RGB WagSet 2 enables, among others:
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.

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. It is described as "DEF" (Fig. 4). Before you start the configuration process,
it is necessary to unscrew the screws (Fig. 4, det. B) and remove the cover (Fig. 4, det. A).

If 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).
