 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.

 Check the Accessories

Network cables are not provided with this product. Please purchase separately.

24 hours passed since the last reception (Reception
monitor flashes red every 2 seconds)

No function

 Time Server Function

The GPS antenna needs to have a stable reception to enable the time server to

operate.

○ Relationship Between Reception Condition and Time Server Operation

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 in
the usage environment.

 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

entered. (See P.21 and P.28)

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 the

time 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 be
checked with SNMP. It may take up to 25 minutes for this product to receive a signal and
correct 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 of
your user account.
