SERIES 90 SYSTEM CONFIGURATION FILE
INTRODUCTION
The system configuration file is used to select the serial I/O device to be used to communicate
with the tester. Either a regular serial port (COM! or COM2) or the Cablescan serial port can be
selected. For the Cablescan port, the IRQ number can also be selected.
The file is a text format file that can be edited by a regular text editor. It has to be placed in the
\S90 directory and named SYSTEM.DEF in order to be read by the Series 90 during startup.
FORMAT
Each line in the text file contains a keyword followed by a '=' character followed by a parameter.
Upper and/or lower case characters can be used for both the keywords and the parameters. If any
keyword is not found in the file, the default value will be used. If the file does not exist, default
values will be used for all keywords. The following keywords are recognized:
COMPORT

Defines what serial device to use
Defines the interrupt number for the Cablescan card
COMPORT recognizes the following parameters:
CABLESCAN Selects the Cablescan serial card (default)
COM] Selects communication port COM!:
