Teltonika NTP001 is a high-precision, cost-effective Stratum-1 NTP server designed for accurate network time synchronization in public and private environments without relying on Internet access. It uses GNSS technology to provide reliable UTC-traceable time, supporting critical applications where precise timing is essential.

• Time Synchronization: Utilizes GNSS as the primary time source to deliver NTPv4 time broadcast over Ethernet (10/100 Mbps) and serial interfaces (RS232, RS485), supporting Unicast, Multicast, and Broadcast modes.
• High Accuracy: Achieves Ethernet NTP accuracy around ±1 ms and typical LAN synchronization ranging between 1 to 10 ms, handling over 300 NTP requests per second.
• Robust Hardware: Powered by a Mediatek 580 MHz CPU with 128 MB DDR2 RAM and 16 MB NOR Flash storage, running RutOS (OpenWrt-based) firmware.
• Multi-Interface Connectivity: Features one 10/100 Mbps LAN port, RS232/RS485 serial ports via 16-pin terminal block, 1 analog input, and 3 configurable digital I/Os.
• Security: Comprehensive security profile including support for pre-shared keys, X.509 certificates, TACACS+, RADIUS, IP/login blocking, and 802.1x client authentication.
• Durable Build & Mounting: Anodized aluminum enclosure with IP30 protection, compact footprint (82.6 × 25 × 83 mm, 180 g), supporting DIN-rail, wall, and flat surface mounting (mounts sold separately).
• Management & Monitoring: Offers Web UI, SSH, SNMP (v1/v2/v3), JSON-RPC API, firmware upgrade support, and Teltonika remote management capabilities.
• Additional Features: Includes Modbus server/client support (RTU over serial and Modbus TCP) and Modbus-to-MQTT gateway functionality.
