Masterclock NTDS Series User Manual – v2 – December 2012

The following RFC2132 DHCP options defined configuration

items are, when available, used by the network device for

configuration purposes:

OPTION

COMMENTS

Time Offset

The value provided will be used for the Time Zone offset configuration, unless it

is defined as zero in which case it will be ignored and the network device will

rely on internal configuration. Note: this option does not provide information

appropriate for dynamic Daylight Savings Time use.

Router

The first IP address provided will be used for router/gateway configuration.

Domain Name Server

Up to two server IP addresses may be specified. Network device will treat

addresses as primary and secondary DNS servers.

Network Time Protocol Server

Up to two server IP addresses may be specified. Network device will treat

addresses as primary and secondary NTP servers.

DEVICE NAME/DHCP NAME REGISTRATION

As mentioned earlier, all network devices should be provided

with a custom name (e.g. “reception-north-wall”). By default,

device names are the product name abbreviation followed by

the last octet of the device’s MAC (Media Access Control)

address (e.g. NTDS12-04:F7).

If a DHCP server is networked when the NTP device is installed,

the unit will be auto-registered with the DHCP server. The

network system administrator can then view this DHCP name

registration and the currently assigned IP address, at the DHCP

server.

DEFAULT PASSWORD

The factory-default password for the network device is: public.

Please use lower case.

RESET FACTORY DEFAULT CONFIGURATION

In some situations (such as a lost password) it may be necessary

to return your device to its factory default configuration. A

[RESET] button is located either on the clock’s rear cover (on

single-face clocks) or on top (on dual-face clocks).

To reset the configuration to factory default:

Press and hold the reset button for 10 seconds (until dashes

appear on the digits) and then release. The configuration will

now be reset, including the password. The unit will need to be

reconfigured to your custom settings.

The factory default displaying local time is

disabled. You must enable and configure

that setting to display local time.

We suggest you use an NTP time server

with a UTC reference to configure the

offset for your Time Zone and DST.

To ensure proper year-around operation,

the automatic DST adjustments must be

configured using the “Daylight Saving

Time” option and not with the “Time Zone”

option.

European customers, please refer to the

“WinDiscovery, DST Settings” section of

this document for additional details on,

setting daylight saving time.

A network device will not function properly

if configured to use DHCP services when no

DHCP server is available on the network.
