purchasing IWAVE FIM-2405. Please use FIM-2405 according to local radio regulations. Before using,
please carefully read this disclaimer. Once the product is used, all the contents of the disclaimer will

not assume any legal responsibility for results or losses caused by improper use, installation,
assembly and modification (including the use of non-specified IWAVE parts and accessories, such as
the radio power amplifier, antenna and SMA extension cord).
2. Precautions for integration
1) Be sure to use the parts provided by IWAVE.
2) Reverse connecting power line positive and negative will burn the device out.
3) Before powering on please make sure the antenna are in good connection and not install or
remove the antennas with power on.
4) Given that the carbon fiber body and metal load may have shielding effects on antenna signals,
they should not be installed between the antenna and ground terminal. Keep the antenna on
board free from winding or blocking by obstacles. The antenna end should be vertically
downward without bending to prevent shortening communication distance and failure
communication.
5) Antennas on board should be kept away from other radio antennas(such as GPS antenna) to
avoid electromagnetic noise and interference.
6) If using PTZ Camera, please do the PTZ self-testing firstly then connect HDMI cable.
7) HDMI cable and antenna on board may interfere with GPS. Please keep the HDMI cable and
antenna away from the GPS module and its cables.
8) Do not disassemble or modify IWAVE FIM-2405. Any problem during installation, contact IWAVE

www.iwavecomms.com
3rd
or IWAVE local branch office.
9) Keep appropriate distances between different electronic devices during installation to minimize
the electromagnetic interference.
10) Before using, please make sure all cables are in good connection and all components can work
properly.
11) After starting the product, the self-test indicators of FIM-2405 will continuously blink for 30s
and then keep bright. Tx camera’s video shown on the monitor connected with Rx means the
device works properly.
12) Check the surrounding environment to ensure there is no other 2.4GHz devices to cause
interference.
13) If you use the Futaba remote controller, Futaba should be adjusted into the French mode.
Otherwise, the video transmission performance will be serious affected.
14) Adjust the Futaba into French mode as following steps:
[LINKAGE MENU]→FRQUENCY→ RTN b→ [AREA]→[FRANCE]
15) Before using, please check the power of RX and TX. If the receiver power off, transmitter on
board will lose connection.
16) Adjusting RX antenna inclination can improve the signal strength and image quality.
17) The camera should be fully charged to ensure normal video output.
18) FIM-2405 support video and duplex data communication. If the video stuck or stopped for
more than 10s. It means the radio signal is weakened or the radio channel is narrowed. In this
case, the aircraft need to fly back to short the distance between TX and RX. Otherwise, the TX
will lose connection.
Notes: Improper operation of FIM-2405 may cause personal injury or damage to properties. Please
pay high attention to operation safety.

3Light 1,2,3 on: Signal Strong
(2) lights of 1, 2, and 3 are flashing repeatedly in sequence which means the device pairing is unsuccessful, and
Rx and Tx do not communicate.
(3) No. 4 is a data communicate indicator. When data is transmitting normally, No.4 light will keep red. Or it will
not light.
(4) LL: LAN LED
No Ethernet connection: not bright
Ethernet connected but no Ethernet data transmission: keep bright
Ethernet connected and Ethernet data normally transmitted: Fast blink
(5) WL: WAN LED
Tx and Rx not communicate with each other: not bright
Tx and Rx wireless communicate with each other but no signal transmitted: keep bright
Tx and Rx wireless communicate with each other and the signal is normally transmitted: Fast blink

5.3. Power on
After checking all the connections are in good condition, turn on
the the video source, LCD display, transmitter and receiver. The
PWR indicator will bright and the whole system starts to work.
5.4. Observe the each indicator’s status
When the device begin to normally start work, all indicators status is described as follow:
1After power on, light 1,2,3 turn green, light 6 turns blue.
2After few seconds, light 1,2,3,6 start flashing. And light 5 keep bright in green color.
3After a few seconds, the device's startup process is completed.
Light 1, 2, 3 keep bright in green color
Light 6 keeps bright in blue color
light 4 keeps bright in red color
Light 5 begins to fast blink in green
4If signal between Tx and Rx is normally transmitted, WL light will fast blink in green.

5.5. Boot up successfully
After successfully connection, the display will smoothly show camera’s video on Tx.
Remark: In UAV application, please make the Tx with Rx connection successfully and the video show on ground
station smoothly then fly the UAV. About how to install the antenna on UAV please refer the following

6. Antenna Installation
6.1. Multi-rotor UAV
1) Using SMA metal shielded semi-flexible blue feeder cable provided by IWAVE to connect the TX
SMA port with antenna.
2) The antenna needs to be mounted vertically downwards.
3) The best installation location is UAV ground bracket. With antenna inside, the bracket can only
use fiberglass material.
4) If the ground bracket is automatically retracted, the antenna can be installed in the lower part
of the aircraft.
5) If the antenna is intercepted by the PTZ camera, the video on RX will appear image stuck or
mosaic. At this you need to adjust the UAV’s flying attitude and angle.

6.2. Fixed Wing UAV
1) Using SMA metal shielded semi-flexible blue feeder cable provided by IWAVE to connect the
TX SMA port with antenna.
2) The antenna needs to be mounted vertically downwards.
3) The best installation position is center of UAV tail, prominent outside the body and vertical
downward.

4) The second optional mounting position is located below the wing and body joints, vertical
down, as far as possible away from the wing but near the machine abdomen, protruding below
the abdomen level.
