Introduction
To download new operating software to the flash memory in the printer use either:
•
Microsoft Windows version 3.xx Terminal mode in conjunction with the Debug Monitor option from the
System menu.
•
Microsoft Windows version 95/98 HyperTerminal mode in conjunction with LCD option from the System
menu.
Notes: It is possible to download new versions of the same software but it is not possible to install
different language firmware or firmware from a different machine variant.
A security feature of the 430 prevents the download of any firmware other than an up-grade of
the firmware, which was originally supplied.

The following equipment is required:
•
An IBM compatible PC (installed with Microsoft Windows version 3.xx, Windows 95 or Windows 98).
•
A copy of the new operating software on disk.
•
A suitable serial communications cable to connect between the PC and printer connector COMM1 (see
Section 5 for connection details).

Using a pre-configured connection cable, connect Com1 of the PC to COMM1 of the 430 Printer.

communications set up as, for example, 430.trm.
