Simplex PoE clocks operate with the IEEE standard for Power Over
Ethernet. The power for the clock is provided by a PoE injector or a
PoE Switch.
After you connect the clock, it will display the IP address associated
with the device.
The Simplex Ethernet clocks are linked together only in that they are
connected to the network and use the same time source. By updating
the clocks from the same time source, the clocks will remain accurate
to 200ms of that source.
There are four things that the clocks need from the network
1. A standard Ethernet connection using minimum CAT5 Cabling
minimum up to 300’ from the switch/router
2. Power over Ethernet using the IEEE 802.3AF standard (48v
DC). If the switch does not have this feature, it can be added
with single or multi port midspan injectors at the switch.
3. An IP address, fixed or provided by network DHCP service
4. SNTP (Simple Network Time Protocol) service from an internal
of external NTP server.
Section 2 contains System Integration information.
Sections 3, 4, and 5 cover the physical installation.
Section 6 contains instructions on how to configure your device using
The diagrams below illustrate three options for system integration with
your PoE-capable LAN.
PoE-Enabled Hub/Switch
In the simplest example, the Ethernet is already PoE-enabled
(802.3AF) and is supporting PoE devices such as IP phones. Simply
mount the Simplex Ethernet Clock and connect it to a PoE-capable
wall jack.
Non-PoE Enabled Hub/Switch and Single Simplex
Ethernet Clock
If the Ethernet is not currently PoE-enabled and is going to support a single
Simplex Ethernet Clock, a Single Port Midspan Power Injector must be
added to the 10/100 BaseT Ethernet LAN.
Note: The power injector must be fully compatible with IEEE 802.3af.
Non-PoE-Enabled Hub/Switch and Multiple Simplex
Ethernet Clocks
If the Ethernet is not currently PoE-enabled and is going to support the
Simplex Ethernet Clocks, a single or multiplePort Midspan Power Injector
must be added to the 10/100 BaseT Ethernet LAN.
Note: The power injector must be fully compatible with IEEE 802.3af.
Recording Location, Static IP Address, and Host Name
In order to make the management of your Simplex Ethernet Clock
system as easy as possible, Simplex recommends that you record the
Clock ID, Location, IP Address, and Host Name for each unit in the
system as it is installed.
The Host Name will be visible in most DHCP servers. It should
describe the location so that the IP Address of a particular clock will
be easy to locate by matching up the Host Name. For example:
Please see page 53 in the Simplex Ethernet Clock Owner’s Manual for
the procedure that can be used to change the Host Name of the
The Simplex Ethernet Clock arrives fully assembled in a single
package.
Inspect all items and report any missing or damaged items using the
standard reporting process on the company web site.
Follow the directions in Section 4 for the desired mounting option.
A separate mounting kit, modelONT4KIT or ONT6KIT for cantilever or
pendant mounting, is available. Unpack the mounting kit and check its
contents against the illustration provided with the mounting kit.
(Contact your local Simplex field office in the mounting kit is missing.)
The Simplex Ethernet Clock is available in a variety of mounting
configurations. Please consult the appropriate system documentation for
your installation requirements.
The following is a recommended procedure for pendant mounting. This
procedure requires a mounting kit, (model ONT4 KIT for four digit clocks or
ONT6 Kit for six digit clocks), and some additional hardware.
PROCEDURE
Determine the clock mounting location.
The illustration above suggests a recommended mounting means for a
pendant mount of one or more Simplex Ethernet Clocks. Supplement the
ONT4 KIT or ONT6 Kit with two suitable locknuts and a length of ¾ “
(1.905 cm) pipe or conduit. If conduit is required, it’s a good idea to
measure and cut to length before beginning the installation.
1. Mark the location where the clock assembly is to be mounted, making
sure that the mounting means is located beneath the data cable outlet.
2. Assemble and tighten the locknuts and pipe length as shown above.
3. Insert enough data cable through the center hole of the mounting kit
so that it protrudes10 to 12 inches (30 cm). Securely attach the
mounting means using fasteners suitable for the surface.
4. Lift the Simplex Ethernet Clock into position and insert the data
cable into the jack located on the back of the clock.
The following is a recommended procedure for cantilever mounting. This
procedure requires a mounting kit, model ON4TKIT or ONT6KIT.
Determine the clock mounting location.
1. Using the template provided, mark the location where the clock is to
be mounted, making sure the center is located over the data cable
outlet.
2. Using a #2 Phillips screwdriver and a 3/8” (.952 cm) wrench,
assemble the Ethernet Clock Mount (Simplex p/n 714755) and the
Ethernet Clock Cantilever Wall Mount (Simplex p/n 714756) as
shown in the illustration in Section 4 of this manual. Join the parts
using the 2 screws, 2 washers, and 2 nuts provided. Make sure that
the 2 washers are fitted between the Clock Mount and the
Cantilever Wall Mount.
3. Insert enough data cable through the center hole of the mounting kit
