Introduction
DJI iOSD is specially designed for DJI autopilot system during the FPV flight or other aero-modeling
activates. DJI iOSD can transmit video and iOSD information in real time, which will help you to obtain the
aircraft status information during a FPV flight. It can display power voltage, flight velocity, height, distance
from the home point, horizontal attitude, GPS satellite number, etc. iOSD and video information are
superposed on the receiver, making iOSD data clearly visible and bringing you a more involved flight
experience.
DJI iOSD should be used in conjunction with a DJI autopilot system. It supports two video input sources
under PAL or NTSC mode, which can be selected remotely by an R/C transmitter switch. The R/C TX
switch can also change the wireless video transmitter channel remotely when user uses the wireless
video transmitter specified by DJI. The iOSD supports online upgrades. The iOSD is built-in BEC, which
is on the one hand for the power supply of the camera, on the other hand for the power supply of the
autopilot system’s main controller to improve the power supply reliability of the main controller.

iOSD Controller ×1
Connect the iOSD controller to your DJI autopilot
system via CAN-Bus. It communicates with the main
controller, receives data from the main controller,
superimposes the data with the video image, and then
transmits the whole information via a transmitter.

CAN-Bus Cable ×2
Video Input Cable ×1
Connect the iOSD with video input source (i.e. camera
or DJI Z15) for video input and power supply, with
maximum current of 1A. If you connect the iOSD to DJI
Z15, please use the 4Pin- Audio Head cable.
If connect to other camera, use the 4Pin cable for the
connection in accordance with the wiring diagram.
Video Output Cable ×2
Only when you use the wireless video transmitter
module specified by DJI, you can use the bi-port cable
to connect the iOSD with the video transmitter module.
Otherwise, you can use the one-port cable for your
own connection in accordance with the wiring diagram.
2-PIN to 3-PIN Cable ×1
Connect the iOSD with the R/C receiver through this
cable. When there are two video signal inputs, it is
used for the selection of video signal sources. It can be
used for the selection of AVL58 video channel.

Assembly
STEP1.
Fix the iOSD controller on your aircraft.
STEP2.
Connect the iOSD with the video signal source, wireless video TX module, DJI autopilot
system and R/C receiver. Make sure the connection is correct in accordance with the wiring
diagram.
STEP3.
Setup a 3-position switch on the R/C TX as the iOSD control switch.
STEP4.
Connect your wireless video RX module with the display screen.
3-Position Switch Control
Choose a 3-position switch and make sure you connect the correct channel of the receiver to the
iOSD switch port.

Position -1 Position -2, (hold position -2 for 1.5s): every toggle from Position -1 to Position -2
increases the channel of the wireless video transmitter module by 1 (from CH1 to CH8), only for
the wireless video transmitter module specified by DJI.

Position -3 Position -2, (hold position -2 for 1.5s): toggle the switch to select the required
video input, when there are two video inputs. Only the toggle from Position -3 to Position -2 can
change the video input source.

Video Output Port
· If you use wireless video transmission module AVL58 specified by DJI, connect through the bi-port cable.
· If you use your own module, please connect through the one-port cable according the pin description.
Channel Control pin:Control signal for the video transmitter channel number (CH1…..CH8).If your video
transmitter does not support this feature, then ignore this pin.
Video and OSD output pin: make sure this is correctly connected.
Positive/Negative voltage of battery pin: its output voltage is equate to the voltage of the battery, supplying
power for your wireless video transmitter. It is recommended to solder the two cables of the same function.
!
Please make sure the input voltage of your own wireless video transmitter is matched to the voltage of
BATT, to prevent damage from your wireless video transmitter module. For example, if the Battery is
6S(25V) and the input voltage of the wireless video transmitter is 3S(12V), then you cannot use the
BATT+ to supply power since the 25V is larger than 12V.

· If you use the DJI Z15, it is recommended to use the 4Pin- Audio Head cable for connecting the iOSD and
GCU. If you use the 4Pin cable, please connect the iOSD to the Z15's GCU according to the above chart.
· If you use your own camera(s), please connect through the Video Input Cable according the pin
description. AV1/AV2 pin:you can select the required input. AV1 is default. POWER pin: supply power
for Video input source such as a camera, with the maximum current of 1A. If the battery is 3S Lipo then:
Output Voltage = Input Votage . If 4S~6S then: Output Voltage=11.2V. Make sure you camera is rated
for this voltage and current(1A), if not, please use a separate battery supply.
· If you use other wireless video transmitter and the rated voltage is over the voltage of BATT+, you can
use the POWER pin to apply power. Make sure the total current consumption of wireless video transmitter
and camera is lower than 1A, otherwise will damage your iOSD.

Using the assistant software, adjust the display position of the iOSD information, upgrade the firmware
and assistant software are available. In addition, the flight data will automatically be saved as files in the
iOSD, which can be viewed by connecting to the PC.
1.
Power on your computer.
2.
Make sure to power on iOSD. Connect the iOSD Controller to the PC with a USB cable. (If the
iOSD is connected to the autopilot system and both of them are power on, and then switch on the
transmitter first.)
3.
Run the iOSD Assistant Software.
4.
If the Data Communication Indicator is Red on, please double check the connections and driver
installation; otherwise if the indicator is blinking Green, go to next step.
5.
Select the Main item to adjust the display position of the iOSD information if necessary. And then
configure the warning of GPS Satellite Number, Distance and Height Range if warnings are
required.
6.
Click the DataView item, and follow the tips to get the flight attitude data, main control input and
output information, etc.
Note:

If you do not configure the Warnings Setting, the iOSD will show warnings in default values.

It will auto detect the firmware version when you open the assistant software and prompt the
check for updates window if your version is not the latest one.

If enter the Data View mode, the iOSD controller will temporarily quit the parameter configuration
mode, and act as a USB Device to connect to the PC. You can manually select and read any data
file from the USB Device. If you need to re-enter the parameter configuration mode, please power
cycle the iOSD.

The speed of data loading will be very slow for large files. For the large file on the iOSD controller,
please copy the file to the local hard drives of the PC, and then open the file for viewing.
