Other Advanced Options
The following information describes other advanced options in FUNCTION PROGRAM. Related
information is located in Creating and Using a Lookup Table, Creating and Using an ASCII
Lookup File, and Creating and Using an ASCII Data File.
Restricting Input to Downloaded ASCII Data Files Only
Use Receive Data
Files Only? N
When this program option is set to 'No', the M3000 allows the user to create data files at the
beginning of FUNCTION INPUT. When this input is set to 'Yes', user input is restricted to the
use of downloaded ASCII data files. For more information on ASCII data files, see Creating and
Using an ASCII Data File. After selecting Yes to this option, the display shows:
Allow Append To
End of File? N
We do not recommend the use of the file append option unless it is absolutely necessary.
For more information on "Allow Append To End of File? Y", see Creating and Using an ASCII
Data File.
Creating Un-Editable Input Fields
A new Data Input Type has been added to the M3000 Program Options that prevents a user from
changing the input data.
Input Type
D,S,Y,E or N: D
The new data type is 'N'. An 'N' Input Type has the same general parameters of a 'D' Input Type
with these exceptions:
1. Data can be entered into the field ONE time only.
2. Once entered, the data cannot be edited. No editing is allowed.
If "Input Type" is set to 'N', "Use Receive Data Files Only" is set to 'Y', and "Auto Advance" is set
to 'Y' then the cursor automatically advances past any imported data and stops in the next input that
requires user input.
New Input Source Type- RS-232 Serial
A new Input Source Type has been added to the M3000 Program Options that allows the unit to
receive serial data during FUNCTION INPUT. Some devices such as scanners, and automatic
weight scales output serial data. This option is controlled from the following display:
Input Source
K,B,S or X: B
When this option is set to 'S', only serial and keyboard inputs are allowed. When set to 'X', the
M3000 accepts ALL input source types.
CAUTION: Selecting "Allow Append To End of File? Y", can cause LOSS OF DATA
when the user EXITs a data file without satisfying the input requirements of
ALL REQUIRED INPUT FIELDS in the last record. When the user
violates this precaution , the M3000 deletes the LAST RECORD in the data
file. This condition continues to occur each time the user fails to complete
ALL REQUIRED INPUT FIELDS and EXITs DATA ENTRY.
