NTP Server Sentinel®Installation and Operation Manual
OVERVIEW
Product Overview
The NTP Server Sentinel® is a standalone "ready-to-run" GPS referenced NTP
time server offering a complete solution for synchronizing the time across TCP/IP
LANs using NTP. The NTP Server Sentinel® combines a GPS receiver with an embed-
ded web based controller and is configured and managed via a web browser. The mon-
itor and control web page displays date, time, locked satellite signal strength with mul-
tiple display features. The NTP Server Sentinel® can handle multiple requests per sec-
ond, making it the choice for providing accurate time information. The concept is as
simple as plugging the controller into the network, attaching the GPS receiver, config-
uring the unit and allowing any client to request “highly accurate” time.
Additional features include; three separate GPS time referenced outputs. The
first is a DPDT relay, which operates at 12:00, 22:00, 42:00, 54:30 each hour and is
user programmable in each of four storage locations for any minute and second each
hour. The second output is an active high driver with a 100 ms pulse each second,
while the third output provides an active high driver in the ESE TC89 or TC90 serial
time code format. Indicator LED's are provided to display; power, 1PPS activity, seri-
al time code activity and time sync relay operation. The NTP Server Sentinel® is sup-
plied with a Garmin GPS18 receiver, which tracks up to 12 satellites. The GPS-18 can
be positioned up to 100 feet away from the controller, using standard CAT5 cable. The
controller may be desk mounted or up to three units may be mounted on our RA-1, 1-
RU rack shelf. The controller is supplied with a domestic DC power supply.

NTP Server Sentinel®Installation and Operation Manual
INSTALLATION
Installation
The NTP Server Sentinel® interfaces to external equipment through removable
euroblock screw terminals. The terminals accommodate wire sizes from 16 - 28
AWG solid or stranded wire. Before installing a wire, remove the euroblock screw
terminal plug and turn each capture screw fully counterclockwise. Strip each con-
ductor to a length of 0.25” and insert the conductor fully into the terminal. Turn the
capture screw fully clockwise to secure the conductor.
Surge Protection
The NTP Server Sentinel® has built-in resistance to voltage changes; we recom-
mend that you use a power surge protector or line conditioner on the incoming AC
line. Lightning strikes and/or other high voltage surges may damage your NTP
Server Sentinel® and connected equipment if it is not properly protected. For light-
ning protection devices, check out www.polyphaser.com and www.itwlinx.com.
UPS Standby Power System
We recommend that you connect your NTP Server Sentinel® to a UPS system. A
UPS helps minimize the risk to the NTP Server Sentinel® and provides power dur-
ing a power outage.
DC POWER connector
This is the connector used to power the unit. Never use any type of power supply
other than the specified power supply.
“CHS GND” Chassis Ground
This is the chassis ground terminal. The station ground should be connected to the
chassis ground terminal using a 20 to 24-gauge wire.
“LAN/NET” network RJ45 connector
Connect one end of the supplied CAT5 (straight or crossover) cable to the desired
ETHERNET (WAN/LAN) or PC port.
“DEF” Defaults button
Hold down this button while powering the device up to reset the unit to defaults.
“1PPS” / “GND” One Pulse Per Second Output
The 1 PPS logic output provides an active high 100ms pulse per second. This out-
put may be used to drive clock systems.
“STC” / “GND” Serial Time Code Output
STC (Serial Time Code) active high driver logic output. Output format (ESE TC90
or TC89) and frequency (30 hz or 60hz) configurable from web interface. Also avail-
able on the BNC connector labeled “STC.”
CAUTION!
Installation of the NTP
Server Sentinel® in high
RF environments should
be performed with care.
The station ground
should be connected to
the designated chassis
ground terminal using a
20 to 24-gauge wire.

INSTALLATION
“TS-K1A / TS-K1B” Time Sync Relay
DPDT relay connections for use with devices that require contact closures for time
sync. Closures are configured from the web interface.
“GPS RCVR” RJ45 connector
Connect the supplied Garmin GPS18 LVC GPS receiver. The receiver must be
mounted in an area that has a clear, unobstructed view of the sky. If the attached 10-
foot cable isn’t an adequate length, you may attach an additional 100 feet of CAT 5
cable. The receiver is equipped with a metric M3 x 4mm threaded magnetic base,
use this to secure the receiver to a user provided mounting bracket. The receiver
may also be secured with a small strip of Velcro. Do not allow the receiver to sit in
water.
GPS Receiver RJ-45 pin-out:
Pin 1 = No connection
Pin 2 = Ground
Pin 3 = Ground
Pin 4 = GPS Receiver, receive data.
Pin 5 = GPS Receiver transmit data.
Pin 6 = GPS Receiver 1 PPS output.
Pin 7 = No connection
Pin 8 = Regulated +5 Vdc used to power the Garmin GPS-18 receiver
(100 ma max).
Front Panel Status Indicators
• Power: Lit when powered up.
• 1PPS: Blinks once per second when receiving valid GPS time data.
• STC: Flashes when serial time code output is enabled and active.
• TS-K1: Indicates time sync relay activity.
Please refer to the appendix for connector layouts.
