The [Status] button takes you to the

“Status” window (page 16), which

includes a Display Snapshot of the digital

time display, constantly updated. This

update is not ultra-precise, but is meant

to give you a remote view of the display

from your computer console for trouble-

shooting and maintenance purposes.

Here you can choose settings such as the

LED brightness level, format of time, etc.

the “NTP OR TIME CODE Client” window (page 15).

QUERY NTP SERVER FOR TIME (NTP

ONLY)

The NTP settings are located in the upper left-hand

section of NTP Configuration window. Note the

two settings: Primary and Secondary.

Primary: The Primary reference information must

be configured in order to acquire time from an NTP

reference.

Enter either the IP address or Internet address/URL

(Uniform Reference Locator) for the NTP reference.

Secondary: If available, enter a secondary

reference for backup.

The primary and secondary server information can

be automatically configured by the DHCP server IF

your DHCP server is configured to do so.

If so, select “Use NTP server(s) address provided

by DHCP server.” (Consult your network

administrator to use this option).

By default, the NTP clock will operate only in

Unicast/Query mode using Server Port 123.

This mode is selected exclusively when neither the

listen for NTP broadcast nor the listen for NTP

multicast modes are selected.
