Video Input Port
·
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 your 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.

·
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.

Important: iOSD can be connected to any CAN-Bus port of the WKM system, BUT should be connected to the NAZA-M or NAZA-M
V2 via the PMU V2 (NAZA-M V2 Accessory). NAZA-M should be upgraded to the firmware version of V3.10 or above when using
with the PMU V2 , with the same assistant software V2.10 of NAZA-M V2. iOSD should not be connected to the WKM and NAZA-
M/NAZA-M V2 at the same time. Refer to the Appendix for more connection details.
