Model 574 Programmable Counting System (PCS)
132 - GSE Scale Systems
is simply compared against the specification, and they
must be identical to be considered a match.
If there are parameters in the line specification,
characters from the received data will be stored into that
parameter. Characters before the parameter in the line
specification must match characters in the received data.
A match occurs when data has been stored into all
parameters in the line specification.
Input specification format lines may be up to 255
characters long, however the input interpreter's input
buffer is only 49 characters long, which is the maximum
number of received data characters that may be
interpreted. When this buffer fills up it is cleared.
Setup
The Input Interpreter is an advanced software feature. In
order for it to function properly, it must be set-up
properly. The setup is stored in electronically erasable
programmable read-only memory (EEPROM) along with
all the other scale setup information.
General Setup
The Input Interpreter may be enabled or disabled at setup
Parameter 900. All remaining input interpreter setup
parameters are always retained regardless of the setting
of this parameter. When this parameter is enabled, all
received serial data is captured and used by the input
interpreter. When it is disabled, all serial data is received
and used by the instrument's command processor.
The line type input specification terminating character is
programmed at Parameter 901. For values from 0 to 99,
the value is displayed on the numeric display, while the
ASCII interpretation of it is shown on the lower line of
the character display. For values greater than 99, only
the value is displayed on the lower line of the character
display.
For each of the eight input specifications, there are three
parameters which must be set-up: type, format line and
macro number.
Input Specification Type
The Type is programmed at parameter 9X0, (where X is
the input specification number, 1 through 8). The
choices for type are: 0 - Unusd (unused), 1 - Char
(character) and 2 - Line (line). Enter the number of your
selection followed by the <ENTER> key to select a
specific selection or press <ENTER> by itself to scroll
through the selections.
When the type is set to unused, the other two parameters
for that input specification are not accessible and will not
be retained in EEPROM. However, they are not cleared
until exiting the setup mode, so changing the type to
unused and then back to char or line does not affect the
input specification format line and macro setups.
Input Specification Format Line
The format line is programmed at Parameter 9X1, (where
X is the input specification number, 1 through 8). The
format line is displayed on the lower line of the character
display, the edit position is the last character on the right.
The numeric display shows the edit position's offset from
the first character of the format line. A solid box
character indicates the end of the format line, a small PA
indicates a parameter and a small CC indicates a control
code. Here the following keys perform special functions:
<Left Arrow> Moves the edit position left
<Right Arrow> Moves the edit position right
<SAMPLE> Expands character at edit position
<Up Arrow> Enter Alphanumeric entry mode
<ENTER> With no entry, enters the parameter
select mode Following an entry, inserts
entry into format line at edit position.
<CLR> With edit position at the end of the
format line will ask if you want to
delete the entire line; press
<ENTER>.
<ENTER> for yes, any other key for no.
Otherwise it deletes the character at
the edit position.
In the Alphanumeric entry mode the <UpArrow> key
and the key <DownArrow> are used to scroll up and
down through the ASCII character set. The
<LeftArrow> key acts as a backspace, removing the
character at the edit position and moving the edit position
to the left one character. The <RightArrow> key moves
the edit position one character to the right and places an
"A" there.
In the parameter select mode the <UpArrow> key and
the <DownArrow> key are used to scroll up and down
through the available parameters. The parameter number
is displayed in the last 2 digits of the numeric display, If
you know the parameter number you may enter it
