Adding or Modifying Communications Mode Settings

You can add or modify the settings for a communications mode object. These values override the values in the initialization parameters file.

  1. Select Admin > Netmap to open the network map.
  2. Do one of the following:
    • To modify an existing mode definition, double-click the mode.
    • To add a new mode definition, right-click in the mode box and click Insert.
  3. Modify the mode settings as required. If you are defining a new object, select either TCP/IP as the protocol to associate with the communications path. Refer to the following table for the definitions, descriptions, and valid values for each field.
    Field Name Description Valid Values

    Name

    The name of the remote node and communications path object types. If you are modifying settings for a remote node, the Name field is not blank. You cannot change the name.

    A 1- to 48-character alphanumeric string

    Protocol

    The type of communications protocol.

    TCP/IP

    TCP/IP is the default value.

  4. To add or update TCP/IP settings, click the TCP/IP tab. Refer to the following table for a description of each field:
    Field Name Description Valid Values

    Buffersize

    The buffer size for transmitting data to and from the remote Connect:Direct® node. This value overrides the value in the initialization parameters file.

    A numeric value from 256–65536.

    The default is 65535.

    Pacing Send Count

    The number of send operations to perform before automatically waiting for a pacing response from the remote Connect:Direct node. A value of 0 indicates that there is no pacing. This value overrides the value in the initialization parameters file.

    A numeric value from 0–63.

    The default is 0.

    Pacing Send Delay

    The amount of time Connect:Direct waits before sending each outbound data buffer to the remote node. This can prevent flooding the network. A value of 0 indicates that Connect:Direct sends each data buffer as soon as possible. This value overrides the value in the initialization parameters file.

    An integer from 0–86400.

    The default is 0.

    CRC

    Specifies whether CRC checking is turned on.

    The default value for the local node is OFF. The default value for the remote node is blank.

    The remote node defaults to blank to simplify the use of the crc.override parameter. When crc.override is enabled in the initialization parameter, only the nodes that require a different configuration need to be changed.

    OFF | ON | blank

  5. Click OK.
