the tubes. For a 4 tube display this would be 4 spaces, for 8 tubes it is 8 spaces, and
so on.
An easier way to display data is to use the „Direct‟ message command, „MD‟. To use
this command the only parameter which you need to provide is the start position of
your text. If you wanted to display the word „HI‟ on tubes 2 and 3, send the following
command
< M > < D > < 2 > < HI >
There is a distinct exception to the use of ACSII characters for the message body
which is related to the use of user defined characters. In this case you need to
provide the binary character number in the range 0-125, instead of the ASCII
character.
2.3.2 Decimal point commands
Decimal points can be independently controlled and in some circumstances they can
also be animated too !
The basic decimal point command operates on a „per tube‟ basis. This means that
for each tube in the display there is a corresponding position in the decimal point
control command which refers to each particular tube.
EG
<P><Tube 1 DP‟s><Tube 2 DP‟s><Tube 3 DP‟s><Tube 4 DP‟s> etc
If we say that you want to turn on the left hand decimal point of tube number 3 then
in conjunction with the „P‟ command we also need to send the „L‟ instruction.
O = Off
L = Left
R = Right
B = Both
It is important when you control DP‟s in this way that you also send the DP data for
every decimal point too. Assuming that the only decimal point you would like to turn
on is the left DP of tube number 3, and you have 4 tubes in the array, you need to
send the following command.
<P><O><O><L><O>
And if you want to turn on all DP‟s, send this
<P><B><B><B><B>
Animating the decimal points is possible using inbuilt routines, but it is important to
remember that these routines are only designed for use with 4 tube arrays. If you
