Immediately after power-up and completion of the internal/external
initialization procedures the MVI46-S3964R with installed 3964R protocol is
ready to serve as an interface between a SLC processor and one or two
communication partners using 3964R protocol. The parameterization of the
module is realized through a configuration file. This is where a differentiation
between the communication modes 3964R with RK512 and 3964R without
RK512 takes place.
The communication mode 3964R without RK512 supports processing of up to
512 bytes.
The serial transmission parameters are optional and can be allocated
independently to each interface. Possible baud rates are 300 to 115200
.
The
following parity setups are possible:
Even, Odd and None
.
5.2.3 General
Concepts
Module Power Up
On power up the module begins performing the following logical functions:
Initialize hardware components
o
Initialize SLC backplane driver
o
Test and Clear all RAM
o
Initialize the serial communication ports
Read module configuration from the Compact Flash
Initialize Module Register space
Set up the communication interface for the debug/configuration port
When this initialization procedure is complete, the module will begin
communicating with other nodes on the network, depending on the configuration.
