6.1. InStRUCtIOnS fOR InStaLLatIOn

► The antenna must be placed outdoor at the top of a building in order to obtain the
widest possible unobstructed horizon around it. Any building or small hill more than
5 degrees above the line of the horizon may obstruct one or more satellites, thus
reducing the performance of the antenna.

6.2. COnnECtIOn tO an Rt4000 OR Rt1000 tIME CEntRE

► An RT3000 or RT1000 time centre is linked by a single two-wire cable connecting
the IRIG B / AFNOR output on the RT B GPS generator (terminal B1) to the syn-
chronization input connection terminals on the time centre.
► The Afnor output is without polarity.

7.1. SWItChInG On

► Connect the 230 VAC supply (115 VAC or 18-72 VDC, 12VDC or 24VDC as
options).

7.2. InItIaLIzatIOn PhaSE

► The initialization phase of the RT B GPS generator starts as soon as the external
power supply is present.
► When the first satellite is locked, indicator LD5 lights.
► The IRIG B / AFNOR code is not transmitted during this phase.
► As soon as the RT B GPS acquires a number of satellites that permits to compute
its position and the UTC time, the «NAV. MODE» indicator LD4 lights and the «IRIG
B» indicator LD2 starts to flash.
► The "PPS PULSE" indicator LD3 shows the PPS (Pulse per second) that is gene-
rated by the GPS card.

Although other systems do not cause much interference to the
antenna, it must not be installed directly beneath radar.
