Inova OnTime Digital Clock Owner's Manual  
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.

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).

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.

The clock’s password prompt appears:  
iclock password:  
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.  
1. Log into the OnTime Digital Clock.  
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

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.

Inova OnTime Digital Clock Owner's Manual  
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.
