Introduction
Thank you for purchasing the TSV-400GP GPS Time Server.
This time server uses a GPS antenna to receive high-precision time information.
Devices such as computers or servers that are connected to the network and use the
standard time synchronization protocol of NTP or SNTP to communicate with this
product can obtain the accurate time.
Also, information about the operating status of the time server can be obtained using
a web browser or SNMP.
At the same time as operating as a time server, the TSV-400GP can be used to
periodically synchronize the time of various devices by turning on the regular time
semiconductor relay output circuit.
The TSV-400GP supports IEEE802.3af compliant PoE (Power over Ethernet) power
supply, and can therefore receive power and operate from an Ethernet cable.

Device Installation
Caution
○When operating this product as a time server, make sure that the
network administrator handles the system. Managing the IP addresses
inappropriately may prevent devices connected to the network from
operating, or cause them to fail.
○Do not attempt to disassemble, modify or repair this device as doing so
may result in electric shock, failure or malfunction.
○Do not install the device in locations that have high temperatures or
humidity. Doing so may cause parts such as connectors to corrode
easily.
○Install the device securely, and avoid installation in locations where it
may be subject to vibrations or impact. Doing so may result in the
product dropping or becoming damaged.
○Do not lay cables where people walk. People may trip over the cables
by accident.
○Do not install in a flammable atmosphere (near gasoline, flammable
sprays, thinners, lacquers or dusty locations) or in a corrosive
atmosphere that contains substances such as acid.

- 5 -
Doing so may result in fire, short circuit or failure.
○Be sure to remove the AC adapter from the socket before installing,
removing and cleaning this device. Failure to do so may result in
electric shock.
○If the device malfunctions due to lightening, etc., immediately remove
the AC adapter from the socket. Doing so may result in fire or short
circuit.
AC Adapter
Warning
○Do not attempt to disassemble, modify or repair this device as doing
so may result in electric shock.
○Do not handle this device with wet hands. (Also, do not handle this
device in humid, damp and dusty locations.)
○Do not pull the cable to remove the AC adapter from the socket.
Connections
Compulsory
○Always disconnect the power supply before starting wiring work.
Failure to do so may result in electric shock or malfunction.
○Always use the specified AC adapter (provided).
Using a different adapter may result in malfunction.
○Always insert the AC adapter into a 100V - 240V AC (50/60Hz)
power supply socket (commercial power supply). Inserting the
adapter into a power supply socket that has a different voltage
may cause fire.
○Do not apply overvoltage or overcurrent to the semiconductor
relay output terminal. Doing so may result in malfunction or fire.
(See P.8)
Product Usage
Warning
Do not use with medical device related systems that directly affect human
life.
Product Disassembly
Prohibited
Do not attempt to disassemble or modify this product. Do not solder this
product. Doing so may result in an accident such as fire, injury or
electric shock, or a malfunction.

○Semiconductor relay output signal
The semiconductor relay output signal turns the output circuit on for 2 seconds every
hour on the hour after the GPS signal is received. (The circuit is an electronic switch
that uses the MOS FET relay.)
If the signal cannot be received, output is stopped after more than 24 hours has
passed from the last reception. Output resumes when the signal is received again.
Output rating
Applicable voltage: 24V DC or less
Maximum current: 200mA
Maximum output on resistance: 2Ω

Installation
[GPS Antenna Installation]
○Selecting the GPS antenna installation location
Install outdoors in a location that has an unobstructed line of sight to the sky.
When installing indoors, install near to a window that has an unobstructed line of sight
to the sky.
Caution
Do not install indoors in a location that does not have a line of sight
to the sky.
Doing so may cause unstable reception or the reception may be
affected by ambient noise, resulting in malfunction.
○Locations unsuitable for reception
- Locations that do not have a clear line of sight to the sky, irrespective of whether
they are inside or outside
- Locations that have an object that reflects or intercepts radio waves near the
installation location
- Near wired window glass, window glass with smoke film attached, metallic slide
shutters or window blinds
- Locations that have a radio transmitting antenna or lightening conductor nearby
- Locations that have high-voltage wires nearby
- Locations that may become submerged in bad weather conditions
- Locations where the antenna may become covered in snow in winter
- Other locations that may be sheltered from or may have obstructions to radio
waves from GPS satellites
○GPS Antenna Installation Orientation
Install the GPS antenna facing towards the zenith
(highest point in the sky)
(cables pointing downwards).
Installing with the case facing sideways or downwards
adversely affects the reception performance of the
antenna.
