Analogue Compass Repeaters 056376/A
Updating the Repeater’s Firmware 8-1
Chapter 8: Corrective Maintenance
The analogue compass repeaters are complex electronic devices, which
are not serviceable in the field down to the level of individual circuit
components. Defective units must be sent back to Sperry Marine for
repair.
Should repeaters require to be re-configured, e.g. after installation of a
new compass source, field service attendance must be requested from
Sperry Marine directly or through an authorized Sperry Marine service
representative.
Maintenance by field service personnel is limited to the software-based
configuration and update procedures supported by the Sperry Universal
Software Instrument application (SUSI).
8.1 Updating the Repeater’s Firmware
The analogue compass repeater supports the uploading of firmware
files using SUSI. This allows to selectively update either the actual
repeater application software (“MCU-Application”) or the bootloader
(“MCU-Bootloader”).
SUSI is able to validate the provided files beforehand, making the file
upload a safe and reliable updating method. In case an upload should
fail for any reason, the repeater will remain fully functional, continuing
to run the previous firmware.
When new firmware is released for the analogue compass repeater,
authorized field service personnel will be provided with the required
files upon request.
CAUTION Risk of damage through unauthorized service
The analogue compass repeaters are complex electronic devices, which
are not serviceable in the field down to the level of individual circuit com-
ponents.
Defective units must be sent back to Sperry Marine for repair.
Note
The analogue compass repeaters are serviced and configured using the
Sperry Universal Setup Instrument (SUSI).
