726 TP Backup

1 Introduction

The program offers the following possibilities:

Ÿ Methods, determinations, sample silos and access control files can be saved

on the PC and reloaded on the 726 Titroprocessor or the data card. These bi­nary files can be sent back to the Titroprocessor to be viewed and edited.

Ÿ Determinations can also be saved automatically to the computer right after

completion, by using the ‘auto save’ function (Destination ‘RS232 x’).

Ÿ The built-in terminal program can be used for receipt and storage of individual

reports on the PC.

The files of the 726 Titroprocessor are transferred to the PC in the background,
work with the computer can continue normally. A small control box informs you
of the status of the transfer.

The 726 TP Backup version 1.0 is designed for the transfer (sending and receipt)
of data with the 726 Titroprocessor and the 5.726.0010 (or higher) program ver­sion.

Switch to the dialog page Configuration of the 726 Titroprocessor to view the
program version.

Please refer to the 8.726.1003 Instructions for Use for operation of the 726 Titro­processor.

726 TP Backup

To save the selected settings in the 726 TP Backup program, first confirm the
settings of the dialog box Port settings by clicking OK. Finally, either the key
combination Shift + F9 can be pressed or the Save command chosen from the

Configuration menu.

Important Note

File transfer from PC to Titroprocessor may cause problems with some Personal
Computers that are equipped with high speed serial interfaces. If you experience
problems with file transfer set the PC’s transmit buffer to minimal size or switch
off the interface’s FIFO buffer.

Switch off the FIFO buffer of the serial interface with Windows 3.x as follows:

Start Sysedit.exe or Notepad.exe from the accessories window and open the

System.ini file (must be present in the C:\Windows directory). Search the
[386Enh] section and modify the COMxFIFO entry to ‘COMxFIFO=0’ (x=1 or

2). Save the system.ini file, close the editor application and restart Windows.

Modify the transmit buffer for Windows 95 as follows:

Click Start on the task bar and then – Settings – Control panel – System –

Device Manager – Ports – COMx – Properties – Port settings – Advanced

(COMx=COM1 or COM2)

Put the transmit buffer to minimal size. Quit the Control panel and restart Win­dows.

3 Data transfer 726 Titroprocessor – PC

3.1 Backing up the 726 Titroprocessor files

It is good practice to save the contents of the 726 Titroprocessor on a PC from
time to time using the 726’s File manager. The following files can be transferred:

• Determinations ( ∗.dtm or any file name )

• Methods ( ∗.mth )

• Sample silos ( ∗.slo )

• Access configuration ( ∗.acf )

Either single, several or all files of a storage location can be backed up.

3.2 File names

In contrast to DOS computers, the files on the 726 Titroprocessor can be freely
named. In particular, characters such as ?, ∗ or + and others can be used.
Moreover, the instrument distinguishes between uppercase and lowercase let­ters.
However, when working with 726 TP Backup, these options should not be used
for the following reasons:

• If the 726 Titroprocessor file name contains characters that are not permitted

by DOS, the file will not be transferred correctly and an error message will be
displayed.

• If files of the 726 Titroprocessor whose names differ only by uppercase or

lowercase notation (e.g. TEST.mth and Test.mth) are transferred to the PC,
only the file last sent will be stored. DOS does not distinguish between up­percase and lowercase notation. The TEST.mth and Test.mth files are there­fore regarded as identical and will be overwritten without warning.

Caution:

With the 726 Titroprocessor always use file designations that are valid
under DOS and unambiguous. Do not use special characters.
