Automation and Control | General

Configuration

  • IP Port: The TCP/IP port that the service will use to communicate.

  • Encryption level: Sets the encryption type used to encrypt messages from the service. The encryption settings here must match those in the receiving device so that the messages can be decrypted.

  • Encryption key: If the Encryption level is set, this field defines the associated encryption key. The key is any sequence of letters and numbers shared with the receiving device. For 128 bit encryption the key must be 16 characters long; for 192 bit it must be 24 characters; and for 256 bit it must be 32 characters.

  • Checksum Type: Sets the type of checksum that will be appended to the end of each control packet. 8 bit Sum is a simple addition of all previous bytes in the packet. 16 bit CRC is a standard CRC (Cyclic Redundancy Check) based on the CRC-16-CCITT polynomial.

Options

  • Numbers are Big Endian: The default method of sending multi byte numbers is Little Endian (least significant byte first). With this option selected, multi byte numbers will be sent as Big Endian (most significant byte first).
  • Allow Status Requests When Not Logged In: When this option is enabled the external program connected to the service can request and receive status updates (e.g. area status) without logging in. The program cannot send control commands (e.g. disarming the area) without logging in with a valid user PIN.
  • Use Logon Lock Out Timer if Incorrect PIN is Supplied: When this option is enabled, if an incorrect PIN is supplied three times in a row the service will block further attempts for 60 seconds.
  • Ack Commands: With this option enabled the service will send an acknowledgment (ACK) packet to the external program after it successfully receives a control command.
  • Expect Ack For Status Monitoring: With this option enabled the service will expect an acknowledgment (ACK) packet to be returned after it sends a status update. If no ACK is returned within 3 seconds the status update will be resent.

  • Resend Status Monitoring If Not Ack after 5 Attempts: If Expect ACK For Status Monitoring is enabled above, this option controls the cut off criteria for unacknowledged status updates.

    When this option is enabled the service will resend each status message until it receives an ACK from the external program. When this option is disabled the service will stop sending a status update if it has not been acknowledged after 5 attempts.

  • Expect Ack for Events: With this option enabled the service will expect an acknowledgment (ACK) packet to be returned after it sends an event. If no ack is returned within 3 seconds the event will be resent.

  • Resend Events if not Ack after 5 Attempts: If Expect ack for events is enabled above, this option controls the cut off criteria for unacknowledged events.

    When this option is enabled the service will continue sending each event until it receives an ACK from the external program. When this option is disabled the service will stop sending an event if it has not been acknowledged after 5 attempts.
