  • Page 16: 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.
  • Page 17 Command Reference". Save your entries with AT&W.  Not all configurations at the i-modul ISDN HIX V4 need to be save actively by entering AT&W. Some settings are automatically saved immediately. We still recommend sending the command AT&W to the...

  • Page 18: Functions

    Functions Establishing or Accepting a Data Connection The i-modul ISDN HIX V4 can call another ISDN TA (ISDN Terminal Adapter) via the phone line and establish a data connection. After dialling a phone number, the i- modul ISDN HIX V4 synchronises with the called TA and opens a data connection.
  • Page 19 ISDN HIX V4 indicates If no connection can be NO CARRIER established, the i-modul ISDN HIX V4 indicates if the i-modul ISDN HIX V4 cannot NO DIALTONE start a dial-up procedure, it indicates In order to change to command...

  • Page 20: Querying The Alarm Inputs

    V4 can send a message in case of an alarm. This message can be sent via data connection, as SMS or as e-mail via a service provider. The i-modul ISDN HIX V4 evaluates a connection of the input to ground as alarm. If no positive edge is counted at least 4 seconds after the negative edge, an alarm will be processed.

  • Page 21: Automatic Call

    The reason for this is that incoming data are immediately transmitted to the called remote terminal. An established connection is indicated by the i-modul ISDN HIX V4 by the "OH" LED and "DCD" LED on the housing front.
  • Page 22 Functions i-modul ISDN HIX V4 In order to initiate an automatic call, use the command The parameter <n> defines the event, that triggers the connection establishment. Replace <n> with the value - "6" for a connection establishment if the control line DTR is active;...

  • Page 24: Disabling An Automatic Call

    ISDN HIX V4 6.2.2 Disabling an Automatic Call If the function "automatic call" is enabled, the i-modul ISDN HIX V4 does not accept AT commands anymore. To be able to configure the i-modul ISDN HIX V4 again, you must disable the function.

  • Page 25: Data Flow Control

    The hardware data flow control works in two directions. When the critical buffer level is exceeded, the i-modul ISDN HIX V4 will set the CTS line to "low" and will thus indicate to the application to interrupt the data flow. When the buffer is emptied sufficiently for the i-modul ISDN HIX V4 to be able to receive data again, the CTS line is set to "high".

  • Page 29: Configuring The Permitted Callers For Remote Configuration

    The i-modul ISDN HIX V4 ignores each incoming call with a phone number, which does not match with one of the entries of the list. The i-modul ISDN HIX V4 compares the number of the caller with each entry of the list for this. The comparison starts with the last digit of the phone number.

  • Page 30: Connection Configuration Of The I-Modul Isdn Hix V4 At The Isdn Basic Access

    ISDN Basic Access 6.5.1 Configuration at Multipoint Interface (PMP, Point-to-Multipoint) In order to operate the i-modul ISDN HIX V4 at a multipoint interface, you must configure it accordingly and configure an own phone number (MSN). The MSN is always configured without area code.

  • Page 31: Control Outputs

    Functions Control Outputs The i-modul ISDN HIX V4 provides two control outputs, OUT1 and OUT2. They can be controlled independently of each other via AT commands. The outputs can also be switched via remote configuration. The outputs remain in a state until this is changed by a switch command.

  • Page 32: Ta+Configurator

    ISDN HIX V4 TA+Configurator The i-modul ISDN HIX V4 has a further command set, the so-called "TA+Configurator", besides the AT command set. This special command set is used in a terminal program after changing to the "TA+Configurator" besides the AT commands.
