Parameterization Data of the 3964(R) Procedure

Introduction
Using the parameter assignment data of the 3964(R) procedure, you can adjust the CP 340
to suit the properties of its communication partner.
Parameter assignment data of the 3964(R) procedure
With the CP 340: Point-to-Point Communication, Parameter Assignment user interface, you
can specify the parameters for the physical layer (layer 1) and for the data connection layer
(layer 2) of the 3964(R) procedure. You will find a detailed description of the parameters
below.
The section "Parameterizing the Communications Protocols (Page 94)" describes how to
enter the parameter assignment data using the CP 340: Point-to-Point Communication,
Parameter Assignment interface.
