Synchronize the Z45 Controller time with Digi Axess

You can synchronize the time between a Z45 Controller and Digi Axess. You can choose from one of the following options:

• Cellular Network: The Z45 Controller retrieves and synchronizes to the time provided by the cellular network. To use this feature, the device must be connected to a cellular network, and at least one cellular antenna (primary antenna) must be connected to the device.

• GPS: The Z45 Controller retrieves and synchronizes to time provided by the GPS or GLONASS constellation. To use this feature, GPS must be enabled on the device, and a both a cellular antenna (primary antenna) and a GPS antenna (secondary antenna) must be connected to the device.

• NTP Server: The Z45 Controller retrieves and synchronizes to time provided by an NTP server. You must specify the IP address for the NTP server is provided on the screen.

• TIME Server: The Z45 Controller retrieves and synchronizes to the time provided by the TIME servers (nist.gov) used by the NIST Internet Time Service (ITS). Note that not all of the nist.gov time servers support the TIME protocol. NIST recommends using the NTP protocol.

To configure time synchronization:

1. Log into the Z45 Controller's web UI.

2. Click Admin Main.

3. In the Interfaces section, click Time Source. The System Date/Time Configuration page displays.

4. From the Time Source list box, select the time source option for the device.

5. If you selected the NTP Server or Time Server options, enter the enter the IP address or URL for the NTP Server or TIME server in the Time Server Address field.
