1. Check the box contents

The Aprisa FE is shipped to you in a box containing the following:

One Aprisa FE radio fitted with power connector.

The Aprisa FE has two chassis depth options:



300 mm depth (part number ...30...)



440 mm depth (part number ...44...)

Two mounting

brackets and 8

screws

DC power cable

3 m

Ground cable 5 m

2. Install the Aprisa FE radio and connect the protection earth

The Aprisa FE is designed to be rack mounted in a standard 19" rack. The internal duplexer and external duplexer mounting are shown below:

The Aprisa FE has an M5 stud earth connection point on the left front of the enclosure to earth the

enclosure to a protection earth.

The antenna feeder cable should use grounding kits for lightning protection as specified or supplied

by the coaxial cable manufacturer to properly ground or bond the cable outer.

Note: The Aprisa FE radio operates within frequency bands that require a site license be issued by

the radio regulatory authority with jurisdiction over the territory in which the equipment is being

operated. It is the responsibility of the user, before operating the equipment, to ensure that

where required the appropriate license has been granted and all conditions attendant to that

license have been met.

Hereby, 4RF Limited declares that the Aprisa FE digital radio is in compliance with Directive

2014/53/EU. The full text of the EU declaration of conformity is available at the internet address

3. Connect the antenna and apply power to the Aprisa FE radio

Connect the antenna to the antenna port N type female connector. If the antenna is not available, terminate the Antenna port with a N type

male 50 ohm terminator (10 Watts min).

The Aprisa FE is operated from a DC source of voltage between +10 VDC and +30 VDC (negative earth) and consumes

up to 35 Watts. External power supplies are available from 4RF as accessories (see the Aprisa FE User Manual).

The power connector (Molex 2 pin female) is supplied fitted to the radio. Wire your power source to the power

connector (- / +) and plug the connector into the radio. The connector screws should be fastened to secure the

connector.

Note: The radio fuses will blow if the connected power supply is over voltage or the polarity is reversed. Two spare

fuses are located inside the enclosure (see the 'Spare Fuses' section of the Aprisa FE User Manual).

Turn your power source on. The radio LEDs will flash orange for one second and then the OK, MODE, USB LEDs will light solid green and the TX

and RX LEDs will flash red.

When the radio has been configured and has registered with the other radio, the TX and RX LEDs will be solid or flash green if the link is

operating correctly.

The Aprisa FE radio is ready to operate.

Warning: On link operation, RF energy is radiated from the antenna. Do not stand in front of the antenna.

4. Connect to the Aprisa FE radio

The Aprisa FE has a factory default IP address of 169.254.50.10 with a subnet mask of 255.255.0.0.

Each radio in the Aprisa FE link must be setup with a unique IP address on the same subnet.

If the IP address of the radio is unknown, it can be changed via the Command Line Interface on the radio MGMT USB port:



Connect your PC USB port to the Aprisa FE MGMT USB port. USB to UART Bridge VCP Drivers are required to connect the radio USB

port to your PC. You can download and install the relevant driver from https://www.silabs.com/products/development-

tools/software/usb-to-uart-bridge-vcp-drivers.



At the command prompt >> type 'cd APRISASR-MIB-4RF' and enter.

- type 'set termEthController1IpAddress xxx.xxx.xxx.xxx' and enter.

- type 'set termEthController1SubnetMask 255.255.0.0' and enter.

- type 'set termEthController1Gateway xxx.xxx.xxx.xxx' and enter.

If the IP address of the radio is known or is the default IP address, it can be changed via the Ethernet port:



Setup your PC for a compatible IP address e.g. 169.254.50.1 with a subnet mask of 255.255.0.0.



Connect your PC network port to one of the Aprisa FE Ethernet ports.



Open a browser and enter http://169.254.50.10.

Note: The Aprisa FE has a Self Signed security certificate which may cause the browser to prompt a certificate warning. It is safe to

ignore the warning and continue. The valid certificate is 'Issued By: 4RF-APRISA' which can be viewed in the browser.



Change the IP address, Subnet mask and Gateway to network compatible IP addresses.
