Page 5: Introduction
Security features include password protection of configuration, encrypted communication, and the ability to disable telnet management access • Adjustable time display brightness • Status display to remotely monitor status and behavior • Selectable Stratum Identification levels ® NTP100 – Rev 2.2.0 Oct-12 © Masterclock , Inc. -
Page 6: Utc/Greenwich Mean Time
The NTP100-GPS derives the precision UTC time that it serves from the GPS satellite network using an internal GPS receiver and requires the connection of a pre-amplified GPS antenna. ® NTP100 – Rev 2.2.0 Oct-12 © Masterclock , Inc. -
Page 7: Installation
If a longer cable is required, cables of various lengths (up to 500 feet) with pre-amplified antennas are available from Masterclock, Inc. [Note: bringing the NTP100-GPS or NTP100-GPS-HS up for the first time with an indoor antenna may prevent or significantly increase the time to first fix.]... -
Page 8: Pre-Installation Checklist
Confirm availability of DHCP/BOOTP server (for dynamic networking configuration) All Masterclock, Inc. network appliances can be provided with a verbose name. The name is not used for any internal purpose by the NTP100 and is arbitrary. It may be useful for organizing and managing devices once installed at a facility. - Page 9 [Note: The NTP100-TC auto-detects and decodes the date encoded incoming time code signal as UTC referenced time and treats the incoming time code signal as UTC referenced. Non-date encoded SMPTE or IRIG-B/B(1) Continue at step 4 ® NTP100 – Rev 2.2.0 Oct-12 © Masterclock , Inc.
- Page 10 Once the NTP100 has a valid network configuration and the IP address of the unit is known, it can also be accessed via Telnet by computers in the same logical network. ® NTP100 – Rev 2.2.0 Oct-12 © Masterclock , Inc.

Input Impedance The input impedance for the Masterclock TC time code decoder circuit is considered to be relatively high , typically >100kOhm. This high input impedance allows for connecting multiple Masterclock TCR load devices in parallel without loading and/or distorting the time code input signal. -
Page 12: Front-Panel Behavior
Up to two server IP addresses may be specified. NTP100 will treat addresses as primary and secondary DNS servers. [WARNING: An NTP100 will not function properly if configured to use DHCP services when no DHCP server is present on the network.] ® NTP100 – Rev 2.2.0 Oct-12 © Masterclock , Inc. -
