b) Copy the cti.ini file created above to the root directory of a SD card and insert that card into the front
panel SD card slot. The file system of the front panel SD card should be either FAT32 or EXFAT. This is the
way they come when newly purchased. If you have reformatted your SD card with the NTFS file system,
or any other file systems, it will not work.
c) Turn off power to the base, remove the controller from the base, set Module Switch 4 to CLOSED position
(and ensure Module Switch 2 is OPEN). Re-install the controller into the base, and restore power.
d) On power up, the controller enters Port Parameter Setup mode and displays PPSt on the front panel
display. While in this mode, the web server can be accessed using the currently active IP address.
However, the controller will not accept connections from Janus Workbench.
e) Next, the controller will attempt to find the 'cti.ini' configuration file in the root directory of the front
panel SD card.
•
If cti.ini file is found, the file is then validated to ensure all the required data is included and correct.
•
If the required keywords are found and validated, the procedure continues at step h below.
f) If any of the following errors occur, PPEr is displayed for 5 seconds indicating a Port Parameterization
Error and the appropriate error (see below) is generated.
•
If a properly formatted SD card is not inserted into the front panel receptacle:
Error 370 (Front Panel SD Card Not Accessible) is reported.
•
If the cti.ini file cannot be found in the SD card root folder:
Error 250 (Front Panel SD Card – Update File Not Found) is reported.
•
If the cti.ini file does not contain the required keywords/values:
Error 260 (Front Panel SD Card - Invalid Update File) is reported.
g) If one of these errors exists, the firmware will repeatedly attempt to perform this operation as long as the
controller remains in this mode. This allows you to insert (or modify and insert) an SD card without having
to reset the controller. Each time you insert the SD card, the operations in steps (e-f) are repeated.
h) If the operation successfully completes, the parameterization data is saved for the next controller startup,
the cti.ini file on the front panel SD card is renamed cti.bak, and PPdn indicating Port Parameterization
Done is displayed on the front panel.
i) To return to normal operation, turn off power to the base, remove the controller from the base, set
Module Switch 4 to the O
j) On power up, the firmware performs subnet validation on the saved values. If they pass, those values are
written into system parameter data. A 'Changed Network Settings' event is generated in the Event Log.
