2.2 Connections
Time Server Rear View
2.2.1Antenna
The outdoor dome GPS antenna is connected through the SMA connector on the rear of the Time
Server. The outdoor antenna uses an SMA to BNC adapter to match the outdoor antenna cable.
The antenna includes 25’ cable with a BNC connector. If the antenna cable is extended, the
cable connections must be located indoors or otherwise protected from the elements. The BNC
connectors are not waterproof. The swivel mount allows the antenna to be mounted in a variety
of locations. For best reception, mount the antenna in a location that has a wide view of the sky.
2.2.2 Power
A UL Listed 5 volt DC power supply is supplied with the unit. Connect one end to a standard
United States 110-120 Volt outlet and the barrel connector to the rear of the Time Server. The
time server will begin trying to find the GPS satellites. On power-up, synchronization to the GPS
satellites will take several minutes. No battery backup of position is provided to allow for a
warm start so the Time Server is always starting from scratch in determining its location to
achieve GPS lock. The time server maintains time during power loss, but the LED display will
blank and the NTP time server engine is shut down.
2.2.3 Network
Connect the 10/100 RJ45 port on the back of the Time Server to a network connection. Verify
that the network settings are correct for your system. See the configuration section of this manual
for more information on doing this.
