9.4 Loading new scale software into Flash memory
Loading new software into the flash memory chip requires a special program, the so-called FlashLoader for the Microsoft
Windows
®
operating system.
The FlashLoader is used to load the software from the PC onto the scale. If for any reason this is not possible, the digital PCB
on which the Flash Memory chip is soldered must be replaced (see Section 4/5 of this service manual).
9.4.1 Prerequisites
To be able to transfer the new software to the scale you need the following:
– PC Microsoft Windows
®
operating system (Version 95, 98, NT 4.0, ME, 2000 or XP)
– Connection cable PC –scale (RS232 cable, 9-pin Sub-D connector m/f)
– FlashLoader application
– File with new scale software
Install both the FlashLoader and the scale software in the same folder on any drive of the Windows PC.
9.4.2 Loading the software onto the scale
Before you can load the software onto the scale, you must connect the scale to the serial interface of the PC with the RS232
cable.
Set the COM1 interface on the scale to the following values:
Operating mode: Dialog
Data transmission rate: 9600 baud
Data bits/parity: 8 data bits/no parity (“8 none”)
Transmission protocol: “No” or “Xon/Xoff”
Start the FlashLoader. The first time it is started it prompts
you to select the interface of the PC to which the scale is
connected.
When you have selected the respective interface, click the
“Proceed” button.
