Set Device Name

To set the device name, select this menu option. Enter the desired device name.

Set/Reset Password

To set, change or remove the password, select this option. Bear in mind that a lost/forgotten password

cannot be recovered [unless a reset to factory default settings is performed].

[Note: the factory default password is: “public”]

[Hint: To remove password protection for a clock, select the Set Password command. You will be

prompted to enter the old password. Enter the old password. Do not enter anything into the New

Password or Confirm Password fields. Click OK to save. Upon you next session, you will not be

prompted for a password for the clock.]

Set IP Configuration

To set the IP Configuration, select this menu option. NOTE: If you select this option, you will be

disconnected from the session upon completion, whether you actually change any entries or not.

You have the choice of using DHCP for automatic IP Configuration or entering the data in these screens

for Static IP addressing. By factory default, the clock is set to DHCP address mode.

If you select DHCP, no other questions will be displayed, you will be disconnected from the session, and

you will not be able to Telnet to this clock until you learn the DHCP-provided IP address. The

WinDiscovery network device management tool can be used to determine the IP address of the clock.

To manually enter the static address IP information, enter ‘N’ for the DHCP (or Enter for the default),

and enter the IP, Netmask, Gateway, Primary DNS and Secondary DNS server.

Set NTP Server Parameters

The network clocks support a Primary and a Secondary NTP source in static IP addressing mode. Select

this option to setup or change the NTP reference sources. Enter the name or the IP address for the NTP

reference server. Enter the server port for each NTP reference source (normally 123). Note that in

DHCP addressing mode, the DHCP server will provide this information.

Set NTP Unicast,Multicast,Broadcast Mode

The NTD clocks are set by default to unicast mode [query] for NTP on a regularly scheduled basis,

factory set to 10-minute intervals. To set the clock to receive broadcasts, set the NTP broadcast option

to ‘yes’. To set the clock to receive multicast messages, set the NTP multicast option to ‘yes’. Enter the

broadcast/multicast port (normally 123).

[Note: If the clock is set to receive broadcasts or multicasts, the clock will not query.]

To return the unit to unicast [query] mode reply ‘no’ for broadcast and multicast options.
