Omega Engineering High Speed Load Cell Interface Card LCIC-WIM-BEN User Manual page 30

4. Programming your Application
The control of the board is by commands and parameters,
described below. You may either use them directly (see also
section D.3), or call an ActiveX (see section 4.3) that does the
work.
4.1 Commands
_ <c/r> signifies a carriage return.
Single character commands (where no <c/r> is required) are used for quick
direct access/control of the card.
Command
Rnn<c/r>
Wnn<c/r>argument<c/r>
(upper case W)
(the Fast Mode is not available with RS485):
u
(lower case u)
U
(upper case U)
x
(lower case x)
Note about High Speed Commands:
a. Parameters: Read & write:
Read parameter #nn.
All values are returned in floating point scientific format,
preceded by nn<c/r> echo and appended by a c/r. E.g.,
the answer to 'R23<c/r>' is '23<c/r>2.560000e+02<c/r>'
indicating that the value of Filter1 is 256.
Write the value argument to parameter #nn.
Floating point values can either be normal or scientific
representation. For example 0.003 could be sent as it is or
as 3.0E-03.After the 'Wnn<c/r>' the board echoes
'nn<c/r>' and after the 'argument<c/r>' the board responds
'argument<c/r>OK<c/r>'. For example, PC sends
'W23<c/r>', the board answers '23<c/r>, the PC then
sends '123<c/r>' and the board answers
'123<c/r>OK<c/r>' changing Filter1 to 123.
b. Fast Mode: Start & stop
Start a 'Fast Mode' session using Filter1 (no LED update).
A timer stamp is appended. Its value is the time elapsed
from start of transmission until end of transmission, in ms.
Start a 'Fast Mode' session using Filter2 (no LED update).
A timer stamp is appended. Its value is the time elapsed
from start of transmission until end of transmission, in ms.
Exit Fast Mode and return to general mode.
In order to exit the fast mode, the 'x' command should be
synchronised, that is, issued upon receiving a block.
29
Action
Terminated by the 'x' command.
Terminated by the 'x' command.
