The corresponding green LED will blink when the following three requirements
are satisfied.
1. The display is powered on.
2. The indicator’s port is enabled to transmit continuously.
3. The wires are connected to the terminal block as previously described.
The display will learn "automatically configure" to the transmitting device when the
LEARN
button is pressed at the end of startup. It will display the BAUD rate and then
display the weight. Pressing LEFT or RIGHT will move the displayed stream
accordingly until the desired data can be seen on the display.
