  • Page 30: Operating Principle

    INSYS 19“ 336 LL Operating Principle This chapter describes the basic procedures to operate and configure a INSYS 19“ 336 LL Modem. The INSYS 19“ 336 LL Modem 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 31 Save your entries with AT&W.  Not all settings at the INSYS 19“ 336 LL Modem must be actively stored by entering AT&W. Some settings are automatically saved immediately. We still recommend sending the command AT&W to the INSYS 19“ 336 LL Mo- dem as your last configuration step to ensure that all settings are stored safely and are available for the next restart.

  • Page 32: Functions

    The automatic baud rate detection enables a continuous automatic adjustment of all parameters (baud rate, data format) of the serial interface at the INSYS 19“ 336 LL Mo- dem in configuration mode. The device will detect during the operation in configuration mode, which baud rate and which data format is applied to the serial interface.

  • Page 33: Phone Connection

    The error correction and the data compression are in this case switched off as well. If the INSYS 19“ 336 LL Modem is operated in this mode, not all functions will be available. The remote configuration and all functions for which a password is required, will no longer be available.

  • Page 34: Data Flow Control (Handshake)

    When the buffer is emptied sufficiently for the INSYS 19“ 336 LL Modem to be able to receive data again, the CTS line is set to "HIGH". Reversely, the application can also indicate to the INSYS 19“ 336 LL Modem to interrupt the data flow.

  • Page 35: Data Compression

    11.4 Data Compression The INSYS 19“ 336 LL Modem supports various data compression types. During the con- nection setup, it will automatically detect the type of data compression used by the re- mote terminal, or it is set to a certain type of data compression. Data compression is only available for error corrected connections.

  • Page 36: Data Buffer For Serial Data Transmission

    When the buffer is activated, the data flow control should be active to avoid a buffer overflow in the INSYS 19“ 336 LL Modem. If the buffer overflows, the data gets lost. If the buffer overflows, the data gets lost. Operation without a buffer and error correction is only useful for special character framings.

  • Page 37: Error Correction

    Functions 11.6 Error correction The INSYS 19“ 336 LL Modem masters the V.42 error correction protocol including the Microcom Networking Protocol Levels 2/3/4 (MNP-2, MNP-3, MNP-4) and the data throughput optimization MNP-10. The V.42 error correction includes the protocols LAPM (Link Access Procedure for Modem) and MNP-4.

  • Page 38: Set Two-Wire Or Four-Wire Operation

    11.8 Adjusting the Transmission Level The transmission level of the INSYS 19“ 336 LL Modem at the leased line can be adjusted. This may be necessary to ensure flawless data transmissions via the leased line. For longer two-wire lines, a lower transmitting level than the preset one may be reasonable, as reflections and echoes in the line may impede the communication between the de- vices.

  • Page 39: Set The Operating Modes Answer Or Originate

    Despite the preset factory default, the INSYS 19“ 336 LL Modem can be reconfigured for the other mode. This may be reason- able if a leased line is being repaired, and a device with the wrong mode is available to replace the affected device.

  • Page 40: 11.10 Switching On The Remote Configuration

    "****" in the data stream and if no data traffic takes place after that for 1 second, the INSYS 19“ 336 LL Modem will switch to the remote configuration. It will then send a re- sponse and a prompt to enter the password of the remote configuration. A particular connection type is not mandatory.
  • Page 41 Complete the remote configuration by entering AT*E.  The INSYS 19“ 336 LL Modem is now in the normal data connection mode. You can now exchange data between your local modem and the INSYS 19“ 336 LL Modem, or terminate the connection.

  • Page 53 Display level of the received signal AT%L The value that is reported from the INSYS 19“ 336 LL Modem equals the already amplified level within the INSYS 19“ 336 LL Modem, not the phone line level. Large AT%L responses imply a low signal level; small values imply a high signal level.
  • Page 54 In the factory settings, the speed limitation is always switched on (AT*L0). If the limitation is switched off (AT*L1), the INSYS 19“ 336 LL Modem will always establish the connection on the phone side with the maximum possible speed (or the speed defined with AT+MS), irrespective of the data rate at the serial interface.
