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 thestandard time synchronization protocol of NTP or SNTP to communicate with thisproduct 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 toperiodically 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.

○ 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 switchthat 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.

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 sightto the sky.
Do not install indoors in a location that does not have a line of sight
Cautionto the sky.
Doing so may cause unstable reception or the reception may beaffected 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 theantenna.

-9-○ GPS Antenna Cable Wiring Precautions
Install so that the cables do not pass over the top of the
GPS antenna case. Doing so adversely affects the reception performance.

○ GPS Antenna Fixing Method[Wrapping around a[Installing on a wall]pole]

To check whether or not this device is operating as a time server, use a web browser
to check the System Information screen. (See P.17) The SNTP Server Status is
Running.
○ Syncing Time with the Time Server
Connect the devices that you want to sync to this device using network cables. The
devices to be synced must support NTP (Network Time Protocol) or SNTP (Simple
Network Time Protocol). (Either version 3 or 4)
Set the time server (this device) IP address as the reference location for time syncing
on the device to be synced. The initial setting is 192.168.0.200. This enables periodic
time syncing. For details, see the instruction manuals of each of the connected
devices.
○ NTP Year 2036 Problem
In NTP (Network Time Protocol), the number of seconds from the base point of
00:00:00 (UTC) on 1 January 1900 is calculated in 32-bit integers, and as a result
integer overflow will occur from 06:28:15 (UTC) on 6 February 2036 causing
erroneous calculations. This device will not malfunction after 2036 because it
references sign bits from internal processing, and therefore this problem will occur in
the NTP/SNTP client software and operating system processing, not on the time
server side. As some devices are not supported, it is necessary to check each device inthe usage environment.

You can check the operating status of the time server and configure the SNMP settings
using the web browser (such as Internet Explorer) of a computer connected to the
network. SNMP (Simple Network Management Protocol) is a protocol for monitoring
devices on a network, and is useful for discovering operation errors in the time server.
○ Returning Settings to Default Values After Changing Settings
Remove all of the wires and then plug in the AC adapter of the signal converter to turnthe power on. Next, use a thin flat head screwdriver or pointed stick to press and holdthe initialization button for at least 5 seconds. Initialization is complete when thereception monitor flashes quickly in orange. Release the initialization button.
When initializing the settings, be sure to first remove the AC

Troubleshooting

1.1. You cannot access the time server
1.1.1 You do not know the IP address→ Press the initialization button to reset to the factory default. (See P.15)
1.1.2 You know the IP address→ Check that the LAN cable is connected properly.
→ Check that access is being performed with an IP address that is within the same
segment as the time server.
Connection is not possible unless the network is within the same segment.
1.2. You cannot log in to the webpage→ Both the user name and password are case sensitive. Check whether "Caps Lock" on the
keyboard has been enabled.
If you have forgotten the user name or password, reset the initial settings, and then set
them again. (See P.15)→ Check that access is being performed with an IP address that is within the same segment
as the time server.
Connection is not possible unless the network is within the same segment.
1.3. You cannot change the settings on the webpage→ Check that there are no errors in the characters and number of characters that you

1.4. You cannot synchronize the time with the time server→ The time server must have had its time corrected. Check that the reception monitor of thetime server flashes in green every two seconds (flashes in two-second cycles). The
system information can be checked on the webpage, or the operating status can bechecked with SNMP. It may take up to 25 minutes for this product to receive a signal andcorrect the time after the power is turned on (if the GPS antenna is installed in an area
where a signal can be received).
→ Check whether communication has been blocked by the firewall function. Open UDP port
123 that is used by NTP/SNTP, and open UDP ports 162 and 163 that are used by SNMP.
→ Permission may need to be given to synchronize the time depending on the execution
authority settings of the OS (operating system). Check the execution authority settings ofyour user account.
