4. Copy all necessary files from a previously existing user to the new ‘operator’ user. This will
transfer system settings and preferences. For example, type ‘cp -pR /home/augie /home/
operator’
at the command prompt. This is a critical step, without the ‘.sea’ directory and other
files, the user account will not work as necessary.
5. Edit the sysinit file located in the ‘/etc/config’ directory and modify the ‘tinit’ line at the end of
the file.
automap -X -d1000 -D1000 &
sleep 1
/sea/bin/security &
tinit -T /dev/con* -c “login operator” -t /dev/con1 &
6. Edit the ‘phapps’ file in the /home/operator/.photon directory by adding ‘M300 -af &’ to the
end of the file to start the M300. If you also want to start another application, for example
SeaWcm utility, then add also a line before the M300 line such as, ‘SeaWcm -auto &’. Comment
out or delete any other programs that are started in this file (for example pterm windows). If you
do not delete or comment these lines out the M300 will not automatically run.
7. Edit the ‘.profile’ file in the ‘/home/operator’ directory by adding ‘ph’ to the file. This command
calls the photon GUI with ‘ph’, then this line executes the command.
LAPTOPSYSTEMSFORM300
It is possible to setup laptop systems running M300, QNX 4 and Photon 1.14. If you have the need
for a laptop system for M300 usage please contact SEA.
FILENAMERECOMMENDATIONS
Please use ‘*.sea' for SEA M300 binary raw files. Also adhere to all other conventions for M300
project file extensions.
USINGMULTIPLEPARTITIONS(MULTI‐BOOT)
If there are other partitions on the system from a DOS/Window environment, you can run the
Fatfsys driver to get access to these under ‘/dos/c’, ‘/dos/a’, etc. Please check the documentation for
the Fatfsys utility under the QNX 4 manual.
TCPVS.UDP
TCP is short for Transmission Control Protocol. UDP is short for User Datagram Protocol. Both of
these allow data to flow over IP networks. There are some basic principals the M300 user must be
aware of since these can be used for data acquisition and transmission.
