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 to avoid electromagnetic noise and
interference. We recommend to make full use of data and video transmitting function of FIM-2430 to
minimize the radio devices quantity on board.
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-2430. Any problem during installation, contact IWAVE 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-2430 will continuously blink for 30s and then
keep bright. Only after the video from the camera shown on the display, then you can confirm that the
device work properly now.
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, the controller should be adjusted into the French mode.
Otherwise, the video transmission performance will be serious affected
14) Before using, please check the power of RX and TX. If the receiver power off, transmitter on board will
lose connection.
15) Adjusting RX antenna inclination can improve the signal strength and image quality.
16) The camera should be fully charged to ensure normal video output.
17) FIM-2430 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.
18) Please use good electromagnetic shielding accessories(HDMI Cable, HD display and so on)

VII. Software Operation
7.1. Two ways for changing the parameters
The parameters can be changed by software IWAVE supplied such as bandwidth, code stream and so on. Two
windows for device on board and ground station can be operated at the same time to do monitoring or
setting. The SNR (db) / RSSI (dbm) will be updated in real time.
Notes：As for one pair of our devices, their parameters should be consistent, which means when you
change one of them, you have to change another one, or they will lose connection.
There are two ways to modify the parameters .
Solution 1. Connect Transmitter and Receiver separately to PC, then change their parameters one by one.
Solution 2. Make sure communication between TX and RX is successful, connect TX with PC to changing

www.iwavecomms.com
13th
another one RX parameters by input its IP address firstly. After changing finish, the communication will fail.
Because the parameters of TX and RX are different now. Secondly, change the TX parameters. After the
changing is ok, the communication will be successful again. If you connect the PC with RX, you need to
change the TX parameters firstly, then is the RX parameters.
7.2. How to use the software
7.2.1. Login
1Open the TDD software
2Inputthe IP address (TX Default IP: 192.168.55.1)( RX Default IP: 192.168.55.2)
3Next click Connect TDD button.
7.2.2. RF Configuration
Take TX as a sample, In RF Part, you can modify six parameters listed
in the following picture: TX Rate, TX Power, Channel Bandwidth,
Channel Frequency, Wireless Distance, TX-RX as the follow pic.

www.iwavecomms.com
14th
TX Rate (Default: QPSK FEC 1/2)
This setting determines the modulation type and rate that the data will
be wirelessly transferred.
‘Auto’ means the system will transfer data at the highest possible rate in
consideration of the receive signal strength (RSSI). Refer to Performance
for a table breakdown of performance at selected rates.
If setting a fixed TX Rate It is recommended to retain a fade margin of at
least 10 dbm for optimum performance. For example, for a link (8MHz
channel) with a signal strength at least –75dBm, a TX rate of 16-QAM
3/4 FEC is recommended. Setting to the highest rate with a poor link
may result in reduced performance.
Channel Bandwidth (Default: 4Mhz)
You can select the channel bandwidth from the list. 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)
2402 - 2482 (1MHz BW, CH 1-81)
2402 - 2482 (2MHz BW, CH 1-81)
2405 - 2479 (4MHz BW, CH 4-78)
2407 - 2477 (8MHz BW, CH 6-76)

www.iwavecomms.com
15th
Wireless Distance (Default: e.g., FIM-2430 30km)
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 may provide a wireless data connection to
many slaves
RX Slave: A Salve may sustain one wireless connection,i.e. to an
Master.
TX Power(Default: 29dbm)
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 into maximum,
but rather for the minimum value required to
maintain an adequate system fade margin.

www.iwavecomms.com
16th
7.2.3. RS1 Configuration
In this section, you can modify two parameters listed in the following
picture: Data Baud Rate and Data Format
Data Baud Rate(Default: 115200)
The serial baud rate is the rate at which modem is to communicate with
the attached local asynchronous device.
Data Format (Default: 8N1)
This setting determines the format of the data on the serial port.The
default is 8 data bits, No parity, and 1 Stop bit.

www.iwavecomms.com
17th
7.2.4. RS2 Configuration
This setting determines which protocol the serial server will use
to transmit serial port data over the TDD-COFDM network.
Remote IP Address
IP address of distant device to which UDP packets are sent when
data received at serial port.
Default: 192.168.55.2(master)
192.168.55.1(slave)
Remote Port
UDP port of distant device mentioned above.
Default: 20002
Listening Port
UDP port which the IP Series listens to (monitors).
UDP packets received on this port are forwarded to the unit’s serial port.
Default: 20002
UDP Timeout(s)
UDP Timeout in second.
Default: 10
Character Timeout(ms)
Character Timeout in millisecond.
Default:10
Max Packet size
Default:1024
7.2.5. IP New Network Configuration
This setting helps you to change the IP address of devices. The
default of master’s IP address is 192.168.55.1. The default of
slave’s IP address is 192.168.55.2
For example, if you want to change the master’s IP address to
“192.168.55”. Please 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 the 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 correct the
salver’s “Remote IP Addr” to “192.168.55.5”.

7.2.6. 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 in each unit on the
network.
RF Encrypt KEY
This is the password, or preshared key that is required by any
device to connect to the wireless interface of the TDD-COFDM.
It is to always have a password defined, and changed from the
factory default.
After you change the ID or the RF Encrypt Key, you need click the RF NEW NET to save the changing.
Note: After many times changing parameters, the software will be unstable. Then you need to click the
RSETTDD Button to restart the software. After restart, the software will be very stable.
