Time
The CTM-200 has an onboard real time clock. The real time clock is used to provide timestamp information
for system generated events and reports. The real time clock is capable of keeping system time with all
power removed from the CTM-200 between 30 and 40 hours at room temperature.
9.1
Time Synchronization
The real time clock (RTC) will synchronize with external sources. External time sources are time from GPS
satellites, Time from the Cellular network and time from an NTP server.
Available features:
•
Set the period for time synchronization to external sources
•
GPS, NTP server or cellular network can be used as a time synchronization source
9.2
Time zones
The default time zone is UTC but is user configurable.

Device Management

Upgrading and Configuring
The CTM-200 firmware can be upgraded locally or remotely over the wireless connection. Firmware images
“.tar” files can be downloaded from the Cypress Solutions repository or hosted on customer supplied
repositories or locally on computer on a local network. In most cases it is not necessary to upgrade firmware
unless a specific feature or enhancement has been added. The firmware update process uses a redundant
firmware image system. If for any reason the firmware upgrade fails, the previous firmware will load
allowing the process to be repeated.
Notes:
•
It is highly recommended to test all device configuration and operation before deploying devices to
remote locations.
