Connector is a 9 pin D-subminiature socket.
Output Pin 2
Signal Ground Pin 5
Pins 4 and 6 shorted, and pins 7 and 8 shorted
The method used to control printing and the baud rate are set in the function menu, See
8,5 and 8.6. When the parameter "trn" is set to "tb" the scale will output a value when
the ENTER/select key is pressed.
If "stb" has been selected it will print once automatically when the scale becomes stable
and if "ser" has been selected it will print continuously.
The data format is as follows:
20 characters are sent with the following fields:
HEAD1 , HEAD 2
1 2 3 4 5
HEAD1 (2 BYTES)
OL - Overload, underload
ST - Display is stable
US - Display is unstable
DATA (8 BYTE)

2D (HEX) = "-" (MINUS)
2E (HEX) = "." (DECIMAL POINT)
20 (HEX) = " " (SPACE
UNIT (4 BYTE), text for units selected, may include leading spaces.
