Configuring a Dial-Up (RS-232) Modem Connection Type

If you specified Dial-up (RS-232) modem from the Connection type drop-down list in the General tab, you will be able to access three extra tabs: Modem options, Modem schedule parameters and Miscellaneous.

Note: The Dial-up option is only available when selecting a multi-site Gateway.
  1. Select the Modem options tab to set outgoing call behaviour to site modem.
    Note: The Remote Baud rateshould not be changed. If you are uncertain about modem setup parameters, consult your network administrator for the settings which apply to your particular hardware configuration.
    • Enter the Code to access an outside line (if applicable).
    • Enter the Remote phone number .
      Note: For reliability and configuration consistency, Kantech currently supports the US Robotics Sportster external modem only.The Modem init settings cannot be changed.
    • Select the Phone line type: Tone or Pulse .
    • Set the Number of rings before answer that will define the number of rings before the modem picks up the call. This option is valid whenever ring schedules are not in effect.
    • Set theAnswer on first ring scheduleoption to configure the time interval during which site modem will be allowed to answer on one ring.
    • Set the Number of retries . This will set the number of calls the modem will attempt to make before giving up.
  2. Move to the Modem Schedule parameters tab to set time intervals during which the gateway or site connects to remote sites or gateways (through modem calls) in order to perform specific tasks.
    • Click on the Retrieve site events button to bring up the schedule selection window. Select the schedule that best corresponds to the time requirements set out for this task. For more information on defining schedules, see Schedules Definition.
    • Repeat this step for If data is modified since last , Report events under prioritycall type and Report events automatically .
    • Define the delay before the system will Fail to report after (mm:ss) .
      Note: To schedule the reporting of events under priority call types, first define Priority call types for items such as doors, inputs and controllers.
  3. Click the Miscellaneous tab to configure how modems handle site incoming and outgoing calls.
    • Check the Use a callback connection option to force the gateway modem to hang up after initial connection to the remote site modem and to stand by for an acknowledgement call from the remote modem. You may also want to customize the Fail to callback delay. Default is set to 1:30 (1 min 30 secs.).
    • This option only applies to the KTES. Check the Enable multiple KTES line sharing option to change the Identification delay (ss) between each KTES. The time range value is between 00 and 20 seconds.
    • Select the Primary host modem in the drop down list. If available, select a backup modem in the Secondary host modem. This setting is useful when the primary modem is busy or fails to take the call.
    • Check After reception stay online for if you wish to limit in-call time to a predetermined amount of time which can be set to anywhere between 00.03.00 and 23.59.59.
    • Check the Call immediately when secondary controller communication failure to be alerted in the event that a secondary controller fails to send data to the primary controller (the one carrying the modem).
    • Check the Call immediately when buffer 70% full to force download of a site controller’s event buffer as soon as it reaches 70% capacity.
      Note: Do not click the Remote modem delays button. All values are factory-set for optimum performances with the supported US Robotics modems. Settings SHOULD NOT be edited unless recommended by Kantech.
