1. Please use the parts provided by IWAVE.
2. Before powering on please make sure the antennas are in good connection and not
install or remove the antennas with power on.
3. Keep the antenna on board vertically downward.
4. Antennas on board should be kept away from other radio antennas to avoid
electromagnetic noise and interference.
5. Do not disassemble or modify IWAVE FIP-2420. Any problem occur during installation,
contact IWAVEor IWAVE local branch office.
6. Keep proper distances between different radio devices to minimize the electromagnetic
interference.
7. Before use, please make sure all cables are in good connection and all components can
work properly.
8. Check the surrounding environment to ensure there is no other 2.4GHz devices or they
will cause interference with FIP-2420.
9. After powering on FIP-2420, the self-test indicator will continuously blink for 30s and
then keep bright. After the camera's video shown on the display, which means the Tx
and Rx work properly now.
10.Before use, please check the power of RX and TX. If the Rx power off, Tx on board will
lose connection.
11.Please pay attention to the angle and direction of Rx antenna during flight. When the
signal is poor or the image quality is not good, adjusting Rx antenna's tilt will improve
the signal strength and image quality.
12.The camera onboard should be fully charged to ensure normal video output.
13.If the video stuck or stopped for more than 10s which means the radio signal is too
weak or radio channel is narrowing. In this case, the aircraft need to fly back to short
the distance between TX and RX. Otherwise, the connection will be lost.

7. Software Operation
Note: Because Tx and Rx are working in pairs, so their parameters need be consistent, which means when
one unit parameters are changed, the other unit parameters need to be change too. Or they will lose
connection.
The following show you two ways to do the parameters settings:
(1)Connect Tx or Rx with PC separately then change their parameters one by one.
(2)When the communication between Tx and Rx are working normally, you can change the remote unit
parameters through the local unit and then change the local unit parameters.
Note: If you find the devices cannot connect with PC, firstly wait for a moment for device finishing its
running process, then try again.
Secondly, check whether the distance between Tx and Rx is too close, increase their distance and try again.
If still failure, try another Ethernet cable.

7.2. RF Configuration
In this section, you can modify six parameters.
TX Rate(Default: QPSK FEC 1/2)
This setting determines the modulation type and the rate at which the data is wirelessly transferred. For
example:
Auto: The data will be transmitted at the highest possible rate in consideration of the receive signal
strength (RSSI)
If setting a fixed TX Rate, it is recommended to retain a fade margin of at least 10dbm for optimum
performance. For example, for a link (8MHz channel) with a signal strength of at least –75dBm, a TX rate
of 16-QAM 3/4 FEC is recommended. Note: Setting the highest rate with a poor link will degrade the
performance.

FIP-2420 User Manual
13
Channel Bandwidth(Default: 4Mhz)
The bandwidth channel can be selected from the list.
Note: Before choosing the bandwidth please refer to the
specifications to see the relationship and performance
between channel bandwidth , throughput and sensitivity.
Generally a larger channel has greater throughput at the cost
of sensitivity, while a smaller channel tends to be more robust,
but at the cost of throughput.
Channel-Frequency (Default: 2479Mhz)
You can choose the frequency from 2402 to 2482Mhz
Wireless Distance(Default: 20km)
The Wireless Distance parameter allows a user to set the
expected distance that the wireless signal needs to travel. The
TDD-COFDM sets various internal timeouts to account for this
travel time. Longer distances will require a higher setting, and
shorter distances may perform better if the setting is reduced.

RX TX Mode
TX Master - A Master provide a wireless data connection to
slave.
RX Slave- A Salve sustain one wireless connection to Master.
TX Power(Default: 33dBm)
This setting establishes the transmit power level which will be
presented to the antenna connector of the TDD_COFDM.
Unless required, the Tx Power should not be set with
maximum value, but rather for the minimum value required to
maintain an adequate system fade margin.
7.3. RS1 Configuration
In this section, you can modify two parameters listed in the
right picture.

7.5. IP New Network Configuration
This setting helps you to change the IP address of devices.
The master default IP 192.168.55.1
the slave default IP 192.168.55.2
For example,you want to change the master's IP address to
“192.168.55.5”. Then do as the following steps.
IP Set : 192.168.55.5
IP Mask Set: 255.255.255.0
IP Gateway Set: 192.168.55.1
Then click IP NEW NETWORK button.
Attention! When you have changed the IP address, you should
correct another device's “Remote IP Addr” into the same “IP SET”, or
the serial port will lose connection.
For example , you have changed the master's IP address to
“192.168.55.5”, the you should also correct the salver's “Remote IP
Addr” to “192.168.55.5”.
7.6. RF New NET Configuration
RF Net ID
Each network of TDD-COFDM modules must have a unique Network
ID. This Network ID must be set same in each unit on the network.
You can change it according to your needs , but TX and RX must have
the same RF NET ID.
Chose the box in front of RF NEW ID , and type in the RF NET ID you
choose , then click RF new NET button.
Select the RF NEW ID, and type in the RF NET ID you choose, then
click RF new NET button.
