Appendix F. Softplane.conf
F.1 Configuring the softplane.conf File
For manual
configuration, configure the softplane.conf file to define pin–by–pin
assignment of I/O functions to connectors on the I/O-62 connector panel.
The file is a commented plain text ASCII file. Since the RVP and RCP8 have virtually no
jumpers, or wirewrap, all I/O configuration on the I/O-62 connector panel is done by
software approach according to this
file.
The file is in the IRIS_CONFIG directory, typically /usr/sigmet/config (this is the
default directory that is factory installed).
The factory
configurations are also available in the /usr/sigmet/template/init
directory so that you can always return to the factory defaults.
1. Login as radarop
2. Type: $ cd /usr/sigmet/config
3. Launch one of the text editors provided in the system:
• $ gedit softplane.conf
A user friendly editor with keyboard commands and mouse support when you are in
X–Windows. It us a little easier to learn than vi.
• $ vi softplane.conf
The generic UNIX editor available on every UNIX system and familiar to many users.
F.2
Softplane.conf Organization and
Syntax
The
softplane.conf file defines the I/O pins on each connector on the PCI cards and on
the connector panel. There are two primary definitions for each pin:
• Physical Interface — the electrical properties (RS422 output, analog input, TTL output,
and so on).
• Logical Interface — the internal variable name that is associated with each pin.
The syntax of the file is:
