AP-GTR2000GD embedded NTP server with GPS time receiver (Gigabit Ethernet, Dual Power)

AP-GTR2000GD embedded NTP server with GPS time receiver hardware receives GPS time information from GPS satellite and performs the NTP(network time protocol) server service for network based application server which requires accurate time information like as CCTV NVR server.  Legacy GPS Time Receiver products only support RS232C Interface but AddPac AP-GTR2000GD supports dual gigabit ethernet port as well as dual RS232 interface for backward compatibility.AP-GTR2000GD embedded NTP server terminal is easy to manage remotely and provides excellent scalability. This device can be applied to various real-time video applications such as video surveillance, traffic management and monitoring for disaster prevention

IP based GPS NTP Server 

AP-GTR2000GD embedded NTP server transmits GPS time information to network based application server which requires accurate time information via ethernet port. In local area network, this device transmits GPS based time information to application server like as CCTV recording serverby using NTP protocol. 

Without GPS based time synchronization or NTP server, if time is passed after installation or in service, each application server’s time clock is mismatched comparing with GPS based real-time. Especially, in case of CCTV application, time mismatching should be solved between real-time and CCTV application server’s current time.  

AP-GTR2000GD provides easy system cabling and Installation service by using gigabit LAN interface and internal GPS time receive hardware module. 

In front of AP-GTR2000GD, there are LCD display for GPS time information and blue LAMP for device status. Also, there are two(2) gigabit ethernet port and console port. At the rear of AP-GTR2000GD, there is one module slot for AP-GPSR2 module. AP-GPSR2 module provides dual DB-9 RS232 interface port and GPS antenna interface port. And, AP-GTR2000GD provides the dual power supply by using SMPS power for redundancy and stability. 

Firmware Upgradeable Structure

AP-GTR2000GD RISC CPU is programmable structure so that user may use the latest features without much effort by simply setting an auto upgrade option or download from the homepage.

Smart Web Manager Function

AP-GTR2000GD embedded NTP server is embedded with Smart Web Manager for system management. User may setup/manage AP-GTR2000GD system through PC, smart phone, and tablet device.

AddPac network products are well recognized in terms of performance and stability in the world.
