Creating or Modifying Communications Mode definition
About this task
Procedure
-
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 below 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.
- To add 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
