3. Operation Notes
INSTALLATION NOTES
To comply with various safety and conformance rulings, the system must be prop erly
grounded. The Scoreboard itself needs to be connected to safety earth, and the
connector should be firmly mated and fixed by use of fixing screws.
When power is applied, the display should respond by a sequence of control messages:
Project number, version number, baud rate and address. After the short start-up
formality, display is blanked. If this sequence is missing, check power source and
connections. The voltage present at the pi ns on t he S coreb oard D -sub sh ould be stable
between 8 and 28 Vdc.
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
002.022 is the project and program version for the Scoreboard
022 repeats the S/W version number
C:9600 indicates the current baud rate setting
A.00 is the address of the display (normally set to 00 if disabled)
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.
If the set-up of the RS property holds a string, the Scoreboard will transmit characters
to the host instrument requesting a message. This will be done repeatedly with
intervals of 1 second if no valid message has been received.
Note that reducing the voltage supplied below 20V will turn off backlight and reduce
current consumption. The operation will otherwise be as normal.
STANDARD PROTOCOL DESCRIPTION
A lot of different protocol schemes may be programmed, and the following text only
describes the factory default setup.
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. Timeout function may auto blank the display after a preset
number of seconds.
<STX>data<CR> where <STX>=ASCII 02d, <CR>=ASCII 13d
data includes minus sign (-), decimal point (represented by '.' or','), 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
.

PROGRAMMING OPERATIONAL PARAMETERS
The PROG Signal (pin 4) will force the display into Programming Mode when high. The
display will show "Programming" and only simple configure commands will be accepted
at 9600,8,N,1. Before and after programming sequence, communication is set to the
selected speed Note that the PROG pin should remain low or unconnected (inactive)
during normal operation. Do not allow unconnected leads to the Prog Pin during
normal operations.

SB SB=02 [enter] set Sign Bit position in Sign Byte (0 to 8)
FT FT=kg [enter] set max 3 character trailing text
BP BP=5 [enter] set Control Byte Position (0=not used)
BM BM=07 [enter] set Control Byte Bit Mask (0/255=not used)

EXAMPLE
To set the baudrate to 4800, issue the command:
cmd[ s=status] >C=4800[Enter]
The PC/terminal will reply with an "ok" if accepted, else "* err".
Use the „S"-command frequently.
