NORMAL BEHAVIOUR
When power is applied, the Scoreboard will go through a sequence of initialisation. By
carefully looking at the display, you will be presented the following data:
888888
all segments are on, then off to verify correct operations
08.25
is the firmware version
A.00
is the address of the display (normally set to 00 if disabled)
C:9600
indicates the current baud rate setting
P: 20
Protocol number or other identification
After initialisation, the Scoreboard will blank with all decimal points activated. This is
the default 'waiting screen' indicating that it is awaiting a valid message.
The Display is set to “Autosearch” by standard. It will try to detect the connection and
data protocol settings by itself. This detection is shown on the screen and can take
some minutes. After the settings were found the display should show the incoming
data on screen. (e.g. the weight sent out by the indicator)
If the screen is still empty after 5 minutes, please deactivate everything, check again
the cables and the indicator interface settings and restart everything.
Note that reducing the voltage supplied below 20V will turn off backlight and reduce
current consumption. The operation will otherwise be as normal.
STANDARD DATA PROTOCOL DESCRIPTION
As a serial display, the message format handled is based on the parameter setting that
defines valid and essential data. The data displayed is replaced each time a valid new
message is received. The timeout function may auto blank the display after a preset
number of seconds.
There are a lot of predefined protocols stored in the Display. The autosearch will
automatically set the correct one (if existing) to fit the incoming Data
The following text only describes the factory default protocol.
Default Protocol
<STX>data<CR>
Where <STX>=ASCII 02d, <CR>=ASCII 13d. Data includes minus sign (-), decimal
point (represented by '.' or',') and leading blanks or zeros.
Addressing Control
<SOH> AA <STX>
Will select display AA (00 to 99). 00 will broadcast to all connected displays.
Addressing is used relatively seldom
