displayed, press the <ENTER> key. After the
parameter is selected, the display will briefly show Set
Formt, followed by Formt = 000. Enter a 3 digit code
that specifies the exact way in which the parameter will
be transmitted. A number between 000 and 255 are the
possible entries. In most cases a format entry of 000 will
suffice and the format entry process can be effectively
ignored. However, if you want to send a parameter in a
particular way, you must add up the values from a set of
choices for that parameter and enter the sum as the
format code. The format selections vary somewhat
depending on the type of parameter that you selected.
These are explained in the following section.
NUMERIC PARAMETER FORMAT
SELECTIONS
The selections for the numeric parameters calculated by
the instrument (GROSS, NET, etc.) are described in
Table 18, Numeric Parameter Formats and Table 19,
Numerical Field Width. Note that the names of the units
are sent in a variable width of up to 6 characters,
consisting of a leading space followed by up to 5
characters of units name. Similarly, when selected,
parameter names are always sent following the data and
after the units name (if sent). The length of the
parameter name will always be 5 characters for numeric
parameters as this is the same name that is displayed
when the parameter is selected during the Weigh Mode.
If a more descriptive name is desired for the
transmission, the format can be selected to send the data
only with the descriptive name programmed into the
Custom Transmit Setup as fixed text immediately
preceding or following the transmitted data. Additional
format options for the numeric parameters are divided
into two categories as shown in Table 19. The first is
Fixed Width where a specific number of digits are
always transmitted for the data. The other variation is
Minimum Width where only the digits necessary to
represent the data are sent, so that fewer characters are
sent for weights closer to zero. In any case, all
transmitted data is formatted to the same number of
decimal places as would be displayed. Choose ONE of
the four choices in Table 18 and add its value to that
selected from Table 19. If a fixed width is chosen, the
fixed width that will be used is specified with setup
parameter P208.XX as a value between 0 and 15. Also,
the plus or minus sign, when printed, is included in the
fixed width. If the transmitted data cannot be represented
in the specified fixed width, additional characters are
sent if needed. Thus very small values for fixed width,
especially zero or one, will produce the same result as a
minimum width selection! These same selections apply
to the vars, parameters 80-89, except that the units
related selections (selections 32 and 64) are not
applicable. These 2 choices may be ignored.
TIME/DATE PARAMETER FORMAT
SELECTIONS
Time-Date is set up at the factory to transmit the format
as: 16:56 pm 05/15/91. If this is satisfactory then the
format code of 000 should be used. Otherwise, add up
the indicated format codes for each of your selections in
Table 20, Time / Date Format Selection. After adding
up the selections from Table 20, the total should be
entered as the format code for the Time/Date parameter.
Each specific combination of choices results in the
transmission of a specific number of characters. The
number of transmitted characters is not dependent on the
current time or date. An example of several
combinations are shown Table 21, Time / Date Format
Examples. Note that transmission of a parameter name
along with the Time/Date is not available as a format
choice. Additional text, such as Today's Date: , may be
programmed as fixed text into the Custom Transmit
Setup in front of the Time/Date parameter entry. Refer
to the section on Fixed Text and use of the % character.
TIME / DATE TRANSMIT CODE UPDATE
Format code 32 allows a time / date type variable
(current time, recalled time, and alarms 1 - 4) to be
transmitted as a numeric value in terms of the number of
seconds elapsed since Jan 1, 1970. This is useful in
uploading time / date information to a computer for use
in a spreadsheet application.
ID PARAMETER FORMAT SELECTIONS
The six programmable ID parameters available in the
instrument may be included in a transmission. Choose a
name to send along with the data. If sent, the name will
precede the data of the ID. If a space is desired between
the name and the data then that should be programmed
into the name of the ID. However, it is often beneficial
to name the ID in an abbreviated form that will fit into
the 5 character display for the benefit of the operator
who keys in the ID during everyday use. If you limit the
name to 5 characters, the ID data can be sent without its
shortened name but with a more descriptive name
programmed into the Custom Transmit Setup as Fixed
Text. Your second decision is to determine the number
of characters transmitted for the ID data. This can be
either the number of characters keyed in as the ID data,
or the maximum data size programmed for that ID.
Refer to parameters P701, P703, P705, P707, P709 and
P711 for programming the maximum size of an ID. All
four possible format choices are shown in Table 22, ID
Parameter Formats. No addition of choice values is
