Chapter 2 Installing
Connecting the GNSS Antenna
Connecting the GNSS Antenna
The antenna connections for the SyncServer S6x0 are made at the BNC female
connector labeled GNSS. Allow at least one hour for the unit to track and lock to
GNSS satellites, though it typically takes far less time provided the antenna has an
adequate view of the sky.
Figure 2-15. GNSS Input Connection
Proper cable, grounding techniques, and lightning arrestors should be used. Mount
the antenna outside, preferably on the roof with an unobstructed view of the sky.
Avoid mounting the antenna near a wall or other obstruction blocking part of the sky.
Mount the antenna well above roads or parking lots.
Connecting Alarm Relay
The alarm relay output is energized (shorted) when an alarm activation on this page
is configured and with the actual presence off an alarm in alarm state:
ALARM=SHORTED
The external Alarm mating connector is not supplied. The mating connector is made
by Phoenix Contact, and the manufacturer's part number is 1827703.
Caution:
The GNSS cables should only be connected while the unit
is properly earth grounded.
Note:
For the best possible timing accuracy the cable delay must be
determined and entered into SyncServer S6x0 with the web interface.
See
for cable delay values of SyncServer S6x0 GNSS
antenna kits.
Warning:
To avoid serious personal injury or death, exercise caution
when working near high voltage lines. In particular:
Use extreme caution when installing the antenna near, under, or
around high voltage lines.
Follow local building electrical codes for grounding the chassis.
