The GPS antenna picks up the time signals transmitted
by the GPS satellites.
The time code received is emitted through NMEA0183
telegram (ZDA and GGA strings). These antennas
guarantee absolute accuracy. A daily time code
reception of a few minutes is sufficient to maintain the
clock synchronisation. The time signal acquisition by the
system connected is normally achieved in less than 15
minutes. However a cold start (e.g. first start on site)
can take more time.
A) Installation and orientation of the antenna
The antenna has to be fixed horizontally, yellow LED
downwards.
The antenna has to be set in a room free of electrical
interference and with a free view of the geographic
horizon. However, installation on the side of a building
orientated to the equator and with a free view of the sky
can be suitable.
The yellow LED is on when the GPS antenna is power
supplied. The LED is blinking every second when the
GPS antenna is synchronised.
The antenna is supplied with a 20 meter cable. The
standard cable can be extended up to 200 m.
B) Connection
Before fixing the antenna at its location, connect it to the
clock in order to test the reception and to choose the
best location. Connect the 4 wires to the system to
synchronise.
C) Fixing
Release the antenna from its wall support fig. 1.
Fix firmly the antenna at its location by respecting the
mounting order.
In case of roof mounting, be sure there is a sufficient
protection against lightning close by.
Fixing with the Ø4 mm screw supplied.
During the reassembly, mount back the antenna over its
support by fixing the cable side first to avoid damaging
it. Fig. 2.
D) Maintenance
The antenna casing cannot be opened. In case of
failure, the antenna should be replaced.
Cleaning: water and soap. Do not use diluting liquid
(Acetone, petrol).
Test: when the yellow LED is blinking every second, the
product connected to the antenna is synchronising (See
manual of the product).
