Performance Verification Procedure
The performance verification procedure verifies that the module is operating within
specification.
Conventions Used In This Procedure
All control of the VX4353 Module will be accomplished through a VXI Slot 0 device.
ASCII characters will form the commands sent to control the module and ASCII charac-
ters will be read from the module.
Throughout this document, software writes to the VX4353 Module will be shown as:
Send “Q1 lf ”
where Q1 lf is the command (Query relay one) terminated with a linefeed character ( lf ).
Send all commands exactly as shown.
Reads from the module are shown as:
Read “0 crlf ”
Where 0 crlf is the ASCII string returned from the VX4353 Module, terminated with a car-
riage return and linefeed ( crlf ). The ASCII string returned from the module will be exactly
as shown.
Unless noted, all commands are sent to the VX4353 Module and all ASCII strings read
are read from the VX4353 Module.
Two characters are used throughout the communication sequences: “ cr ” is the carriage
return character (character 13) and “ lf ” is the line feed character (character 10). These
characters are the terminating characters for communication. These characters are shown
throughout this document in the font shown here. Most reads from the VX4353 Module
are terminated with both characters and are shown as “
crlf ”. Writes to the module require
only a “ lf ”, but both characters may be used.
An ASCII upper case letter “O” will be shown as “O” whereas a ASCII zero will be
shown as “0”.
