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.

UTC information from GPS and QZSS satellites
*Reception from Quasi-Zenith Satellite
Obtains highly precise Coordinated Universal Time (UTC) information from GPS and QZSS satellites and provides accurate time information in response to client’s requests.
Overview of the Quasi-Zenith Satellite System (QZSS)
When QZSS (Michibiki) becomes a four-satellite constellation in 2018, three satellites will be visible at all times from locations in the Asia-Oceania regions. QZSS can be used in an integrated way with GPS.
Compatible with a PoE power supply
The unit is compatible with a power supply from a LAN cable. This means it can be installed free of the constraints of the power supply’s position.
CE Marking certifi cation compliant/ RoHS compliant
An environmentally-friendly product free of hazardous substances
No need to use dedicated application software
Functions as an SNTP server.
Network protocol: NTPv3/v4, SNTPv3/v4
There is no need to install a dedicated application software on your computer, meaning that the product can be used with any OS and in any use environment. Connect the product to your computer to confi rm items and specify settings via a browser.
The product is available for a reasonable price, a feat made possible by specializing it for time synchronization. We highly recommend this product for customers who have refrained from introducing time servers because of their high prices.
The antenna can be installed outdoors
A lightweight, compact, separate-type unit with an antenna that can be installed outdoors
The GPS antenna comes with a 5-meter cable for outdoor installation (IP44 equivalent). Consisting of a separate antenna and signal converter, it allows for fl exible installation and does not take up a lot of space due to its compact dimensions.
In addition, the use of separate cables enables it to be extended by up to 600 meters. This means you can set up the antenna in a place with good reception of satellite radio waves.
Reception monitor included in the package
The reception monitor of the signal converter allows you to confirm the signal reception and operating conditions of the equipment.
Two lines of semiconductor relay output
The unit can turn on the semiconductor relay output circuit for two seconds every hour on the hour, at the same time as operating as the time server. This means it can also be used to set the equipment clock on a reguarl basis.
