6.3 ANTENNA CONNECTION
 Choose the most adaptable antenna for the installation. The antenna must have an
impedance of 50 ohms to the equipment transmission frequency. Install the antenna
in accordance with the manufacturer’s instructions.
 Use a cable coaxial, avoiding as much as possible large cable lengths. Cable
impedance is 50 ohms.
 Measure the ROE of the installation. Never accept a ROE greater than 2.
 If a duplexer module or a band pass filter is required, adjust them to the work
frequency before starting up.
6.4 SWITCHING ON THE EZPRO25 RF
 Check the connections between the modules.
 Check that the power supply source is connected correctly.
 Check that the RF SMB cables are connected correctly (see Rear View diagram Ref.
10).
 Check the connections of the antennas in the RPA P25 and RRX modules.
 Only in case of the EZPRO25 RF check the 50Ω load is connected to the rear TNC
connector in the RPA P25.
 Check that the Ethernet connections to the CNC/Gateway are in accordance with the
configuration.
 Check that the RPS P25 module LED SUPPLY is on.
 Activate the power on switch on the RPS P25 module.
 Check that the 24V LED and the 13.2V LED on the RPS P25 module or the 26.4V
LED and 13.2V LED on the RPS P25 module are on and check that the LEDS ON are
switched on for the other modules.
 Wait for the EZPRO25 RF to start up.
 Check that the mobile equipment is registered in the EZPRO25 RF.
Note: see section 5 for more information on references for the different modules and LEDs.
