Operating Principle
This chapter describes the basic procedures to operate and configure an
i-modul
ISDN HIX V4. In general, the i-modul ISDN HIX V4 is configured and operated via
AT commands. You can enter these commands yourself with the help of a terminal
program and the AT command reference.
5.1
Operation with the Terminal Program
In general, any terminal program can be used. We recommend the program
TeraTerm by T. Teranishi under Windows. It is available free of cost on the
Internet at http://hp.vector.co.jp/authors/VA002416/teraterm.html. You can
use the program "minicom" if you work in a Linux environment.
Caution!
Damage of the serial interface!
A possible direct connection of the serial interface of the i-
modul ISDN HIX V4 with a typical RS232 interface of a PC
overloads components of the module due to the higher
voltage levels.
Use an RS232 level converter (e.g. MAX232) to adjust both
interface types correctly.
