RFI-148 & RFI-900 High Output Power Paging Transmitters User Manual Page 35 of 134
Each fault action operates as a fault itself; therefore when a fault action is taken, it can be seen as latched in
the faults menu and logged in the fault history. Fault actions are latch-only and can only be cleared through
user intervention. Any actions performed are reverted once the fault action is cleared.
5.2.2 Fleeting Faults
The minimum fault duration parameter determines how long the source of a fault is active until it is reported
to the fault interface. A fault that does not reach the minimum fault duration will not be logged, activate a
hardware alarm or trigger a fault action.
5.2.3 Combined Fault
The combined fault is an optional fault that will become active if any fault within the combined fault set
becomes active. Each fault can be configured to be part of the combined fault set. The combined fault will
only become inactive when all of the faults in the combined fault set return to inactive. The combined fault
has a dedicated alarm output.
5.2.4 Hardware Alarm Outputs
A hardware alarm output can be assigned to each fault (see Appendix A.4 for the LIU interface pin-outs).
When the fault is in the active or latched state, the respective alarm will be set to active. Multiple faults can
share the same alarm output. The alarm output will only be set inactive if all of the faults that use that alarm
output are inactive.
A list of hardware alarms available can be found in section 3.7.
5.3 Remote Firmware Update and Snapshot
5.3.1 Update
The remote firmware update feature is used to upload a firmware image to a paging transmitter for feature
additions and/or bug fixes. Remote firmware update requires a Cruise Control connection to the paging
transmitter and a valid RFI-148/900250 firmware image file.
The firmware update process has two stages: uploading the firmware image to the paging transmitter and
applying the firmware image.
FIRMWARE IMAGE UPLOAD
To upload the firmware image to the paging transmitter first connect to the transmitter using Cruise Control.
In the Cruise Control interface select Device -> Load Firmware from the toolbar. In the new window
that appears, navigate to the directory where the firmware image file is located, select the file and click
Upload. The upload process is displayed on the status bar in Cruise Control, near the bottom right. Once the
upload is finished, the status will display “Monitoring”.
Note that at this point the firmware image has not been applied. The firmware image is kept in non-volatile
storage until it is required.
