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
10.1
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.
•
Not all wireless networks offer "public" IP addresses that are remotely accessible; some are firewall
protected to allow access from either the same IP pool only or restricted IP addresses. Contact your
wireless network provider or administrator to determine what options are available.
Some device management options can work with dynamic/non-routable IP addresses.
•
Some networks will force device IP addresses to change at regular intervals. Without proper
configuration, this could cause a remote device to become inaccessible if the device IP address is not
known. The CTM-200 can be configured to generate a report when the IP address of the device changes.
