AT command set
All parameter can be changed by using an extended AT command set described in this chapter.
Please check if the factory setting will fit with your environment. The factory setting is
described (highlighted) in the parameter list shown in chapter “AT command set” (see below).
If you want another configuration as set in the factory default setting, please do the follow-
ing steps:
•
Connect the ID-90 to ISDN interface
•
Connect the PC’s com-port to the DTE interface of the ID-90.
•
Connect the power supply to the mains socket.
•
Start a terminal emulation on your PC, please verify that the baudrate setting
of the terminal emulation fits those of the ID-90.
•
Set up the parameter of the ID-90 from the terminal emulation and save
the parameter using the AT command set.
Example:
To change the used B channel protocol to X.75 please enter the following
commands:
ATB10<
↵
>
(set protocol to X.75)
AT&W<
↵
>
(save the new configuration)
•
Leave your terminal emulation and start your application program.
With the exception of the command A/ (Repeat command) all commands begin with the pre-
fix AT and AT!, where the prefix AT! is used to identify commands to the analogue V90
option. Commands are terminated with
automatically cancelled by longer input. Blanks are ignored, capital/small letters are not sig-
nificant.
The parameter settings of the ID-90 obtained when using the AT commands can be perma-
nently stored (AT&W) and are not lost by resetting or by leaving the AT command mode.
To enter the AT command mode during an active data connection you must use the follow-
ing sequence (“Escape sequence”):
at least 1 sec pause <+><+><+> 1 sec pause
The time gap between all three plus signs may not exceed 1 sec.
The escape sequence is transmitted transparent to the remote device.
