GPS SYNCHRONIZATION
4.1
GPS Synchronization Overview
Mercury employs optional GPS-based timing to synchronize the operation of the network if
necessary. An optional GPS antenna such as the Trimble Bullet III antenna or equivalent as
noted in the following section can be ordered. When used, GPS information can be retrieved by
the Command Line Interface (CLI) or SNMP interface.
4.2
GPS System
The GPS system consists of a Mercury internal GPS module connected to an external active
GPS antenna connected to the female GPS antenna port.
4.2.1 Internal GPS Module
The internal GPS module includes an oscillator that may be synchronized by the GPS satellite
network via the external active (+5V) antenna. A female SMA connector is provided for the GPS
antenna connection. The recommended antenna is the Trimble GPS antenna as shown in Figure
4-2.
