User Interface Module

Introduction

The User Interface module is able to perform many functions, such as downloading system software to the CSP, sending interactive configuration and query messages, and sending a configuration script file to configure the CSP. The module should be able to send a string of hex bytes to the CSP so that at any time you can send any message to the CSP and receive a response.

Create your User Interface Module so that you can disable the features of a message but still send the message and receive a response. That way, when Excel provides you with new messages as part of a software update, you can test the messages before you embed them in your applications.

Queries

Excel provides many messages that allow the host to query the CSP. Be sure to include all of the query messages that could apply to your application. Queries are important for debugging, because they retrieve a great deal of helpful information from the CSP. Queries are also important to ensure that new configurations are correct.

Query messages include the following:

• E1 Span Query

• PPL Audit Query

• Card Status Query

• Fault Log Query

For a complete listing of query messages, see the API Reference.
