DOT MATRIX DISPLAY DURING SETUP
The character programmed at the current location within
the Custom Transmit Setup will be shown in the lower
rightmost position of this display. Any preceding
characters are shown ahead of it on the second and first
lines of the display. For instance, if part number were
entered, the display would show:
ART_N
UMBER
Special characters are used to represent the characters
required to transmit parameters, control codes, ASCII
extended codes, and the end of the table. Parameters are
represented by a compound p/a while control codes and
extended codes are represented by a single character
combination c/c. These special characters may be
expanded to clarify their use by pressing the <PRINT>
key. Control codes, standard ASCII characters and
extended codes (greater than 127 decimal) are expanded
to their decimal value. In addition, control codes are also
shown with their standard two or three character
abbreviation and their control character representation.
For example, the carriage return would be shown as:
<CR> ^M=13.
Extended codes are shown with the letters EXT-* where
the * is replaced by the corresponding ASCII character.
The parameter codes are expanded to a five character
representation of their name along with a 3 digit code
representing the selected format for that parameter. For
example, the Gross Weight being transmitted in format 3
would be depicted as: F:003 GROSS
The Dot Matrix Display is also used to prompt you
through the process of selecting an item for transmission
and during the process of deleting a previous setup.
FIXED TEXT SETUP
The Fixed Text portion of a transmission is entered into
the setup where it is to appear within the transmitted
data. A maximum of 49 characters may be entered at any
one time before pressing <ENTER>. Press the
<UpArrow> key to begin an entry. This places an A in
the lower right position on the display. Use the
<DownArrow> and <UpArrow> keys to scroll forward
or backward through all possible characters. Press
<RightArrow> when the desired character is displayed.
This shifts the chosen character to the left making room
for the next character, which is first displayed as an "A".
This new character is then set to its desired value. Press
<LeftArrow> to backup through the setup if required.
When the text entry is complete, press the <ENTER>
key to store the data.If an alpha keypad is available, then
the text characters may be entered directly. Alpha
keypads can be used in a variety of ways such as with the
GSE computer 550 simulation software terminal window
of the, by connecting a computer in terminal mode to the
Comm Port of the instrument, by using the alpha keypad
sold with the GSE Model 625, 550 and 570 or by
downloading a setup file from a computer through the
Comm port of the 574.
NOTE:
Be careful when downloading the % character which is
used to execute commands. If a % character is part of the
transmit setup, then a double percent character %% must
be entered. For those who prefer, the ASCII characters
may be entered one at a time using their 3 digit decimal
code number preceded by a decimal point entry. For
example, to enter the letter Z you would
press <.> <0> <9> <0> <ENTER>. This entry
procedure is the same as for ASCII control codes (see
following section).
CONTROL CODE SETUP
ASCII Control Codes (0 to 31) and Extended Codes (128
to 255) can only be programmed by keying in a decimal
point followed by the three digit decimal value of the
desired character. For instance, to transmit a line feed
(which has a decimal value of 10), you would key in <.>
<0> <1> <0> and press <ENTER>. A special code has
been created which combines a carriage return with a line
feed: .256 <ENTER>. However, this code still takes up
two elements in the Custom Transmit Setup. Refer to
Table 16, ASCII Control Codes for a for a complete list
of codes.
PARAMETER SETUP
Parameters stored by the unit are added to a transmit by
pressing the <ENTER> key while you are at the desired
location of the Transmit Setup. The display will read
Pick Parm: for about one second, then the display will
read Parm= Gross. Press the <UpArrow> or
<DownArrow> keys to scroll through the possible
selections such as Net, Tare, ID #1, etc. Parameters may
also be chosen by directly keying in their parameter
number followed by <ENTER>. This simplifies
creation of a computer based setup file. The available
parameters and their numbers are listed in Table 17,
Parameter ID Numbers. When the desired parameter is
