Installation & Operation Manual
1 Introduction
TimeMachines Precision Clocks (TMPCs) provide an accurate synchronized time source. TMPCs use Power over
Ethernet (PoE) and Simple Network Time Protocol (SNTP) to make installation and setup as clean and simple as
possi le. Connecting the clock to a PoE ena led Local Area Network (LAN) Ethernet drop is all that needs to e done.
2 Installation
2.1 PoE Connection
TMPCs require connection to a PoE ena led LAN. There are two ways of going a out this, one is to have a PoE switch
and the other is to have a PoE injector. PoE injectors are offered through TimeMachines as an accessory.
2.2 Net ork
Beyond connecting to a PoE ena led LAN, nothing else is required to get TMPCs up and running. IP, Netmask, Gateway,
and DNS addresses are all setup using Dynamic Hosting Configuration Protocol (DHCP) y default. Static addresses may
e assigned y accessing a configuration we page. The default time server is set to nist1-chi.ustiming.org ut can e
changed using the configuration we page. These processes are descri ed with further detail in the Configuration section.
2.3 Mounting
TMPCs may e surface mounted, rack mounted, or in a dual mount racket (using two clocks).
Required tools: hammer, drill, 1/4” drill it, screwdriver and pencil. Mounting options are optional.
2.3.1 Surface Mounting to Dry all
1. Mark the holes to e drilled ased on the spacing of your specific clock. 12.5 inch centers for the 2.5 inch digit
clocks as well as the 4 inch y 4 clocks, and 16 inches for the 4 inch 6 digit clock.
2. With a 1/4” drill it, drill through the two marks.
3. Insert an anchor into each of the 2 holes using a hammer.
4. Insert a screw into each anchor leaving a 1/16-1/8 inch gap etween the head of the screw and the mounting
surface.
5. Connect the network ca le to the ack of the clock.
6. Place the keyhole slots on the ack of the clock over the screws and secure it into place.
2.3.2 Rack Mounting
1. Attach an ear to each side of the clock.
2. Attach clock to rack.

ILLUSTRATION: Attaching Rack Mounting Ears
2.3.3 Dual Clock Mount Bracket
Materials Needed:
1. Two TimeMachines clocks of the same size
2. One Dual Mounting Bracket (760-265-000, 760-445-000 or 760-465-000)
3. 3/4” pipe, el ows, flange. Depending upon how you want to mount the clock determines what pipe lengths and
fittings you will need. The Dual Mounting Bracket accepts any 3/4” tu ing with NPT (National Pipe Threads)
threads on the ends. This product is availa le through local hardware stores or large national chain stores.
4. Ethernet ca les long enough to run from the PoE injector or PoE router/switch to the clock through the 3/4” pipe.
When threading the ca les through the pipe it is recommended that you run oth ca les at the same time – one in
front of the other.
How to mount two clocks in the dual mount racket:
1. Take two TimeMachines clocks and match where the notch is on the display cover – this is where the Ethernet
ca les will enter into the clock displays. The Dual Mount Bracket can e placed on the ottom or on the top of the
clocks. If needed, the display can e inverted so that the ca les can run through the racket and down into the
ackside of each clock.
2. At the ends of the clocks, leave the screws out a out ¼” so that they can e inserted into the key holes on the
Dual Mount Bracket.
3. BEFORE you mount the clocks into the racket, run two Ethernet ca les through all pipes and fittings that will e
used to hang the clocks. Connect the ca les to the clocks and then mount the clocks into the racket.
4. Secure the racket to the clocks y tightening the screws on the ends of the racket into the clock.
5. Begin to tighten the pipe into the racket. Start from the pipe/Dual Clock Bracket connection out to the
connections for the wall or ceiling.
6. Secure the entire fixture to the wall or ceiling.
7. Connect the Ethernet ca les.
8. Power up the PoE injector.

Installation & Operation Manual
3 Configuration
3 1 Web Page – Default pass ord is “tmachine”
All TMPC parameters are accessed on the configuration we page. The page can e accessed y pointing most any we
rowser at the IP address of the TMPC. The initial IP address can e found y using the push utton (dou le-click)
located on the ack of the TMPC. After making changes to the configuration page the “Save Settings” utton must e
pushed to su mit form data. If the changes made do not take effect, the “Restart” utton must e pushed to restart the
clock allowing changes to e applied.

Installation & Operation Manual
3.2 Net ork
By default the network parameters are setup up using DHCP. In order to set static values, uncheck the DHCP check ox
and enter new values in the address fields. If the values aren't changed the current addresses will e kept. The TMPC
must be restarted for these changes to take affect. Addresses in the Network section must e entered in Ipv4, dotted
quad, format.
3.2.1 IPv4 and IPv6
oth IPv4 and IPv6 are supported for static and DHCP setup. Set the parameters to match your network setup.
3.2.2 DNS
If using fullyqualified domain names for the time servers, then DNS entries must be included.
3.2.3 Mask HTTP Access on Subnet
Check this box to only allow setup of the TM1000A, through the web interface, from the local sunnet. This
provides a measure of security for the device from outside the subnet attack.
3.2.4 Mask NTP Access on Subnet
Check this box to only allow NTP access from the local subnet. Traffic originating from sources other than the
local subnet will be rejected.

Installation & Operation Manual
3.3 Time Synchronization
NOTE* If any timezone settings are changed, the changes will not take effect until the next SNTP Resync Period.
3.3.1 SNTP Servers
The first entry (Primary SNTP Server) sets the address of the SNTP server, where where the TMPC gets its timing
information. In case the Primary SNTP Server is unreacha le the TMPC will fall to the Backup SNTP Server. Both DNS
names (time.nist.gov) and IPv4 (192.43.244.18) formats are accepted.
3.3.2 DHCP Option 42 – NTP Server Setting
The TimeMachines display products support DHCP option 42 which allows the DHCP server to serve the IP address for
the device, as well as the IP address of time sources to e used y devices on the network. Up to two can e specified
for use y the TimeMachines displays. When a DHCP set NTP source is used, the we page will display “DHCP Set: IP
Address” in place of the stored configuration. It is possi le to save these if the we page is updated which then in the
a sence of a DHCP provided time server, would then attempt to e used as written and fail. Consult your DHCP server
documentation on how to add these settings.
3.3.3 Time Zone
Selecting the Time Zone sets the offset the clock will display from Greenwich Mean Time. All fields have a predetermined
offset except for CUSTOM.
3.3.4 Custom Time Zone
If CUSTOM is selected for the Time Zone then this field is edita le. Set the desired custom offset y using the drop down
menus to select hours, minutes and (+/-).
3.3.5 SNTP Resync Period
The SNTP Resync Period entry sets the period etween SNTP requests. Enter the num er of hours and minutes

Installation & Operation Manual
separated y a colon (Hours:Min). The default setting is 0 hours and 10 minutes and is the recommended update interval.
3.3.6 T elve Hour Time
Select 12 or 24 hour time. When the ox is checked the TMPC is in 12 hour mode, when the ox is unchecked the TMPC
is in 24 hour mode. The default setting is 12 hour mode. In the 12 hour mode of operation AM hours will display a dot in
the upper left corner of the display. PM hours will display a dot in the lower left corner of the display. (In 24 hour mode
there will e no indication of AM or PM)
3.3.7 24-Hour Mode Leading Zero
When checked, and the clock is displaying 24 hour time, a leading zero will e added to times with single digit hours, such
as 00-09 hundred hours.
3 4 Daylight Savings
Daylight Savings Time (DST) varies greatly from one country to another and sometimes even within countries themselves.
As a result there are many parameters used to handle all of the various rules that are in use throughout the world. The
default setting uses the rule that is o served y the majority of the United States.
NOTE* If any DST settings are changed, the changes will not take effect until the next SNTP Resync Period.
3.4.1 Daylight Savings (DST Options)
The Daylight Saving Time Drop down, allows you to select AUTO, OFF, or CUSTOM. When AUTO is selected the clocks
use the default US Daylight Savings start and stop dates. If OFF is selected the clock does not adjust for Daylight Savings
Time. If CUSTOM is selected the user can specify a custom start date with a start time and stop date with a stop time. The
user can also adjust the ias of the offset.
NOTE* If a US Time Zone is selected then and DST setting of OFF is not allowed. If a DST setting of OFF is needed the
Time Zone should.
3.4.2 Fixed Day
The Fixed Day check ox indicates whether or not DST occurs on a specific date. For example, if DST started on March
1st of every year, the Fixed Day ox would need to e checked. The Fixed Day ox is important in that it changes how the
Start and Stop parameters function. Based on the Fixed Day Check ox certain drop down menus will e availa le for
editing.
3.4.3 Start/Stop Date
The Start and Stop Date parameters indicate when DST changes occur.
• The first drop down is only used on floating day start time (i.e. 2nd Sunday of the month). If fixed day is selected this
option is greyed out.
• The second drop down allows the user to select the day of the week you want DST to start or stop. This parameter is
also only availa le in a floating day scenario.
• The third drop down allows the user specify the month of the start or stop date. This field is always used.
• The last field is the date, this is only used when a fixed is used (i.e. June 4th).
3.4.4 Hour Bias
The Hour Bias parameter allows the user to input a custom hour and/or minute offset if a CUSTOM Daylight Saving Time
is chosen.

Installation & Operation Manual
4 External Connections and Interfaces
4.1 External Connection
External connection will require the user to make a connection from the clock's internal relay to an external system. The
TimeMachines Clock alarm closes an internal relay. The pinout of the connector is as follows:
ILLUSTRATION: Connector for Relay
Pin 1: Approximately +12V maximum current of 50mA
Pin 2: Relay Normally Open
Pin 3: Relay Common
Pin 4: Relay Normally Closed
Pin 5: Ground
Small, low power piezo uzzers or lights can e driven directly from the clocks power supply. For larger loads, an
intermediate relay is recommended.
*NOTE: This connector is not provided with purchase. If you are interested in information on o taining this part contact
TimeMachines. ([e-mail])
4.2 Push Button
4.2.1 Changing the Time Zone
Using the push utton provides a quick way to set the time zone with
out having to access the configuration we page. With every push of the utton the GMT offset decreases y 1. Since the
default offset is -6, pushing the utton once would set the offset to -7. Once the negative offset reaches its limit (-11) the
next offset is the maximum positive offset (14).
4.2.2 Scrolling the IP address
The push utton also provides a quick way to determine the IP address of the TMPC. A rapid dou le push of the utton
will cause the IP address to scroll across the display.
4.2.3 Set Parameters to Default
One way to set all parameters to their factory default values is to hold the utton on the ack of the clock down when the

Installation & Operation Manual
clock is powered up. If done successfully, three “8's” will scroll across the display efore entering the usual start up
routine.
5 Troubleshooting
5.1 Flashing Seconds
There are two instances when the seconds (6 digit clock) and the AM/PM dots will flash to indicate a pro lem.
5.2 Lost Link
If the seconds and the AM/PM dots are flashing it is possi le that the link was lost, check to make sure everything is
connected properly at oth ends of the ca le.
5.3 Missed NTP Packet
If an NTP packet was sent ut a reply wasn't received the seconds and AM/PM dots will flash. This can happen every now
and then, the flashing will stop as soon as the TMPC completes a successful send and receive cycle. If the primary server
can no longer e reached the ackup server will ecome the primary server. This is o serva le y looking at the
configuration we page, if the primary and ackup servers display the same address(primary will e in IPv4 format) than
this scenario has occurred. If oth servers fail the seconds and AM/PM dots will continue to flash until the issue is
resolved. Log into the configuration we page and set new SNTP servers.
5.4 Unable To Access Web Page
This can occur for many different reasons. Below are a few examples with ways to potentially fix.
-Make sure the PC eing used is on the same su net as the clock.
-There are a few antivirus programs that may prevent accessing or viewing information on the we page. To avoid this try
temporarily disa ling efore attempting to access the we page. Once you have made your changes re-ena le security.
This will not affect the function of the clock only the we page access.
-Some of the lesser known we rowsers may not e compati le with the TimeMachines we interface. Try using a
different rowser such as Firefox or Chrome.
