Examples:
With Gateway Address: Without Gateway Address:
[NET0] [NET0]
usingdhcp = false usingdhcp = false
ip = 198.18.74.56 ip = 198.18.74.56
subnetmask = 255.255.255.0 subnetmask = 255.255.255.0
gateway = 198.18.74.1
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.
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 until the
CPU starts up in normal operating mode (with Module Switch 4 set OPEN).
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 (g) below.
e) 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.
f) 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 remove, modify, and insert the
SD card without having to reset the controller. Each time you insert the SD card, the operations
in steps (e-f) are repeated.
g) If the operation successfully completes, the parameterization data is saved in the Janus CPU for
the next controller startup and PPdn indicating Port Parameterization Done is displayed on the
front panel.
Note: The cti.ini file on the SD card is renamed cti.bak to prevent the same network settings
from accidentally being used to configure another Janus CPU.
h) To return to normal operation, turn off power to the base, remove the controller from the
base, set Module Switch 4 to the OPEN position, re-install the module into the base, and restore
power.
i) 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.
