In this chapter shows how to install QT-6100 systems and peripherals.
2-2-1. How to load IPL (Initial Program Loading)
Normally, IPL is not necessary since the terminal has efficient programmable options to
meet your circumstances.
In some cases, you need to change the application program to meet your requirements, the
IPL is necessary to download the application program to the terminal.
To load IPL, there are two methods:
1) From PC to a terminal via RS-232C
2) From CF card to a terminal
