Creating or Modifying a Communications Path Definition

The communications path defines the physical communications path between the local Connect:Direct® node and one or more remote Connect:Direct nodes.

  1. Do one of the following:
    • To modify a communications path definition, double-click the definition in the CommPath window.
    • To add a new communications path, right-click the CommPath box and click Insert.
  2. To define a communications path, type the name of the communications path in the Name field, and select the protocol to associate with it: TCP/IP.
  3. Define a new mode or assign an existing mode to the communications path.
  4. To associate an existing mode with the communications path, select the mode from the Selected Mode drop-down list.
  5. To define a new mode to associate with the communications path:
    • Click New.
    • Type the name of the new mode in the Name field.
    • Select the protocol to associate with the mode: TCP/IP, and click OK.
  6. To add or update TCP/IP settings, click the TCP/IP tab. Refer to the following table for the name, definition, and valid values for 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
