Section 1: Introduction to Inova OnTimeTM Digital Clocks
The Inova OnTimeTM Digital Clock brings all the advantages of Power over Ethernet (PoE)
technology to the marketplace in a real-time synchronized system of clocks.
PoE is an exciting and relatively new technology that allows devices to get both power and
data over standard network cabling. It’s the same technology that powers Voice over IP
phones. Delivering both data and power over one set of wires simplifies installation, saves
space, and eliminates the need for electrical outlets at the clock mounting locations.
Additionally, the option of centralized UPS backup allows PoE devices to continue running
even in the event of a power failure.
Note: The local area network must support IEEE 802.3af Power over Ethernet in order for the
PoE clocks to operate.

Inova OnTime Digital Clock Owner's Manual
Section 5: Digital Clock Configuration
Once a clock is installed, the next step is to confirm or set the configuration . Though there
are a number of settings you can confirm or change on a clock, you should concentrate on
four configuration items initially. These include:
•
•
•
•
An IP address so that the clock can communicate on the network.
A network time server so that the clock knows which computer to synchronize its time with.
The local time zone so that the clock can display the correct local time.
The Daylight Saving Time (DST) rule so that the clock can automatically adapt to local DST.
Before working with these settings, however, you have to consider which configuration
method to use. You have three options:
Configuration Method
Description
Reference
This method is the only way to address and
configure a group of clocks without requiring a
telnet session into each clock. Clocks are factory
set with DHCP enabled.
Section 6
The recommended method is to
assign both the IP address and all
options via a DHCP configuration
string.
Using this method, the DHCP server is set up
with a clock configuration string. Clocks will
automatically request the configuration string
when they request an IP address.
The second method is to assign an
IP address via DHCP and set
individual configuration options
via a telnet session.
Clocks are factory set with DHCP enabled. The
options may be set using telnet commands.
Section 7
Section 7
The third method is to assign an IP
address and individual
configuration options via a telnet
session.
Use telnet commands to assign both a static IP
address and the appropriate configuration
options.
Table 2: Clock Configuration Methods
To learn more about the recommended method of using the DHCP configuration string,
continue with Section 6. To learn more about using a telnet session exclusively, refer to
Section 7.

Inova OnTime Digital Clock Owner's Manual
Section 6: Using DHCP for Addressing and Configuration
Configuration Planning
The OnTime Digital Clock allows you to benefit from a DHCP option that automatically
configures five settings when a clock is booted up. This option reduces the work required to
configure multiple clocks, because, rather than configuring each individual clock though a
telnet session, the configuration is done one time at the DHCP server. Note that because the
DHCP server is likely controlled by your network administrator or IT group, you will want to
discuss this topic with them and enlist their help in configuring the DHCP server.
The clocks are factory configured to request DHCP service, and further, to request a
configuration string using DHCP private option 230. This DHCP configuration option can be
used to establish these required settings:
The DHCP configuration option can be used to set these required settings:
•
•
•
Time Server - A network time server so that the clock knows which computer to
synchronize its time with.
Time Zone - The local time zone so that the clock can display the correct local
time.
Daylight Saving Time - The DST rule so that the clock can automatically adapt to
local DST.
The DHCP configuration option can also be used to establish these optional settings:
•
•
24 hour – The factory default is 12 hour time. Set this option if 24 hour time is
desired.
Show/hide colon – The factory default is to show a colon as a separator between
hours and minutes. In 24 hour time mode, some users prefer to turn the colon
separator off (for example, to show 2301 instead of 23:01).
The recommended practice is to load the configuration string into the DHCP server and then
try it with one clock by re-booting the clock. As the clock boots, it will send out a query
requesting a response from the DHCP server that includes an IP address, subnet mask,
gateway information, etc., as well as the configuration string associated with private option
230. When the DHCP server replies to the clock with the command line associated with
option 230, the clock will automatically use the command line contents to establish its
settings. Once you are confident that the one clock is properly configured using these
settings, you can then feel free to add additional clocks to the network knowing that they
will automatically receive the proper configuration settings as well.

Inova OnTime Digital Clock Owner's Manual
Here are some things to keep in mind as you set up and use DHCP private option 230:
•
A clock must be re-booted to request a new configuration string from the DHCP
server. The clock does not automatically request a new configuration string at the
expiration of the DHCP lease interval.
•
If private option 230 is not configured on the DHCP server, this does not cause an
error condition on the clock. Rather, the clock will receive an IP address from the
DHCP server in the usual fashion but the clock’s settings for Time Server, Time
Zone, DST, etc. will not change.
•
If private option 230 is already in use for another purpose on the DHCP server, it
should not interfere with the operation of the clocks. However, in order to use the
DHCP configuration feature, the clock must be set (via a telnet session) to request
a different private option – e.g., private option 231. See Setting a Different
DHCP Option Number on a Clock on page 12 for additional information.

Creating a DHCP Configuration String
The following table describes the five options that can be used in a configuration string
when establishing a private DHCP server option for automatically configuring the clock. The
format used is option name=option value, with the options separated by semicolons in the
configuration string. This string is added to the DHCP server, as described in the next
section. (See Table 4 for example configuration strings).

Table 4: Examples of Common DHCP Configuration Strings
Setting a Different DHCP Option Number on a Clock
You do not have to use DHCP configuration option 230 for the clocks. You can also create
custom options using a different option number. Suppose private option 230 is already in
use on your DHCP server and you want to configure your clock to use another private option
instead, for example option 231. The ipconfig command can be used to set a different DHCP
option number on the clock or to disable this feature altogether. The ipconfig command is
defined in Appendix A.
Verifying the DHCP Configuration Settings on a Clock
The dhcpconfig telnet command lists all the configuration settings that were retrieved by
the clock from the DHCP server and that are currently in effect. If an error arises while
parsing the DHCP options received from the server, the error will be shown in the
command’s output. Look on the next page for an example.

into the clock from a PC using telnet:
1. From the Windows Start Menu, choose Run.
2. When the Run window appears, type cmd and press Enter.
3. When the command line window appears, type a telnet command like this where you
substitute for xxx.xxx.xxx.xxx the known IP address on your network of the PoE clock:
telnet xxx.xxx.xxx.xxx
The clock login prompt appears:
Digital Clock
Welcome to Clock Version xxx
iclock login:
Additionally, the clock’s service light begins to blink.
4. Enter the clock’s login ID (iclock).

5. Enter the clock’s password (the default is timely).
The clock’s telnet prompt appears:
iclock />
You are now ready to set configuration using the telnet commands.
Accessing Help Commands
For help with a specific telnet command, at the prompt, you have two options:
help or ? along with the command.
For example, to see help for the display option:
display ? or help display
Assigning an IP Address
There are two options for assigning an IP Address to each OnTime Digital Clock:
•
•
DHCP Address [Factory Default]
Static IP Address
Setting the DHCP Address
The factory default is DHCP. When connected to the network, the clock will request DHCP
service. The letters DHCP may be displayed briefly on the screen. If the DHCP message
remains in place, then DHCP service is not available.

Inova OnTime Digital Clock Owner's Manual
Setting the Static IP Address
To enter a fixed IP address into your clock’s firmware, start a telnet session with the clock
and the use the following command option:
ipconfig -a xxx.xxx.xxx.xxx -m yyy.yyy.yyy.yyy -g
zzz.zzz.zzz.zzz
where xxx.xxx.xxx.xxxis the IP address, yyy.yyy.yyy.yyyis the subnet mask,
and zzz.zzz.zzz.zzzis the gateway address. All fields must be provided.
Note: Your IT staff must authorize and provide a static IP address to prevent operational
problems which might occur if that address is applied to another device on the network.
Specifying a Time Server
The network time server on the LAN, WAN, or on the internet may be specified by IP Address
or by Host Name.
•
•
Specifying by IP address is typically only safe if the address of the server is under your
IP Group’s control. When specifying time servers on the internet, use the Host Name.
Specifying by Host Name requires that a DNS server is accessible to the clock:
• If IP addressing is static, the DNS servers must be identified and configured
as well.
• If IP addressing is via DHCP, the DNS servers are typically already
automatically configured (do not over configure!)
The process for specifying a time server is the same for both Host Name and IP Address.
2. At the prompt, type: sntp –h.
3. Press the spacebar.
4. Enter the Host Name of the time server – e.g.
5. Press the Enter key.

Inova OnTime Digital Clock Owner's Manual
Testing the Time Server Synchronization
It is always a good idea to test the synchronization between the clock and the time server. To
do that, perform these steps:
1. At the prompt, type: sntp -s (Be sure there is a space between sntp and -s)
2. Press the Enter key.
The clock displays SNTP settings and immediately attempts a synchronization with the
specified host (either the Host Name of the time server on your network or with an outside
time standard).
Selecting the Time Server
The default time server is set to ntp. inovasolutions.com. In general, this setting should be
changed to an internal time server under IT control. There is more information on NTP, SNTP
Selecting Time Zones
Coordinated Universal Time (UTC) is a time standard based on the time at zero degrees
longitude (also known as Greenwich Mean Time or GMT). Time zones around the world are
expressed as positive or negative offsets from UTC. The default time zone setting for the
clock is UTC -5, which is the time zone for (GMT -5) Eastern Time (US & Canada). You can
change this setting with the following command:
timezone –N [or] timezone N
where N=the time zone offset from UTC, -11 to 12.
Note: If you’re not sure what time zone offset to use, check the time zone value used on a
Windows PC on your network; double-click the time in the Windows service tray (in the lower-
right corner of your screen) and choose the Time Zone tab.

Appendix B: SNTP Basics
SNTP is an acronym for Simple Network Time Protocol. SNTP is widely used to
synchronize time on computers. Certain computers within a LAN or on the internet have the
responsibility of maintaining accurate time in order to provide a time standard for the
network. Your network administrator should be able to direct you to an appropriate local
time server for your environment.
The OnTime Digital Clock must be configured with the network location of a time server.
The default time server is an internet time server operated by Inova.
Periodically, a computer transmits a time query in order to synchronize its time with a time
server. Every two hours the OnTime Digital Clock transmits a time query to the time server
and the time server replies. With the reply in hand, the clock calculates the time offset, or
correction, that it needs to apply to its current time and then makes the update.
In the event that the time server does not reply, the OnTime Digital Clock continues to
display time while it retries the time server. After repeated unsuccessful tries, the clock
illuminates its Service Light (an LED dot at the lower right-hand side of the clock), indicating
that the displayed time is no longer synchronized.
