RFI-148 & RFI-900 High Output Power Paging Transmitters User Manual Page 37 of 134
To create a snapshot, run the “Take Firmware Snapshot” routine. The paging transmitter will continue
operating normally during the snapshot process, which takes up to one minute to complete. The progress of
the snapshot is displayed in the “Snapshot Progress” field.
The snapshot can be reverted to at any stage. This can be useful to revert back to a ‘known good state’ if the
paging transmitter has been misconfigured or has been updated with an unwanted firmware update. To revert
to the snapshot run the “Roll Back to Snapshot” routine. The paging transmitter will reset and take up to ninety
seconds to revert back to the snapshot firmware and configuration. After reverting to a snapshot the paging
transmitter will start up with the firmware update exception fault latched to notify that the snapshot was used.
By default, the paging transmitter has a factory snapshot that contains default factory firmware and
configuration.
5.4 Time
5.4.1 Real Time Clock
A battery-backed real time clock is used to track the passage of time. An accurate time is not essential for the
operation of the transmitter, but aids diagnostics and troubleshooting. The time is used for:
• Generating time stamps for:
o The transmitter fault history.
o Firmware update images.
• Transmitter uptime since power-up.
• A short history of transmitter events (PTT on, off).
TIME ZONE
The time zone can be specified in hours and minutes as an offset from Coordinated Universal Time (UTC).
5.4.2 SNTP Client
The transmitter supports time synchronisation using the Simple Network Time Protocol (SNTP) version 4.
The SNTP client can be disabled or set to unicast mode. In unicast mode, the paging transmitter will query the
configured time server for time updates at a configurable interval. By default the SNTP client is disabled.
