camera and/ or A/V transmitter when necessary. Please do not connect this pin to the A/V

link VCC if it is a 12V system. The black is the common ground of the A/V link. It is

suggested to place a ferrite coil near the connector to ﬁlter the noise to prevent OSD

image distortion. This 4-pin connector cable is supplied as per shown in Figure 1.3. Please

note that the ground/ black is on the most right of this port.

1.2.2 Connection to the GPS

Module/ USB Data Module:

This connector is for the GPS module and USB data module connection. These two

modules are supplied in this kit as shown in Figure 1.4 and Figure 1.5, and they must not

be connected to the OSD main board simultaneously. When GPS module is connected,

the black/ red/ blue pins connect to the ground/ +3.3V/ data TX of the GPS module, which

are the black/ red/ blue wire of the GPS module receptively. The forth pin marked with

white is not connected at this time. The GPS module must be placed on the plane with the

sticker facing up towards the sky without any blocking (especially blocked by conductive

material, such as metal and carbon-ﬁber) to maximise the GPS satellite signal reception.

And make sure the GPS module is kept away from the power/ RF components such as

motor, motor speed controller, radio transmitter/ receiver. When USB data module is

connected, the black/ red/ white pins connect to the ground/ data TX/ data RX of the USB

data module, which are the black/ red/ blue wires of the USB data module. The second pin

marked with red is not connected. Please note that the ground/ black pin is on the most left

of this port.

1.2.3 Connection to the Infrared Sensor Module:

This connector connects the infrared (IR) receiver module for the reception of the IR signal

from the remote controller. The IR receiver module shown in the Figure 1.6 must be

connected, and the IR remote controller shown in Figure 1.7 must be pointed to the IR

receiver module reception window in hemispherical shape when performing the OSD

system conﬁguration. The black/ red/ blue pins connect to the ground/ +3.3V/ data output

of the IR receiver module, which are the black/ red/ blue wire of the IR receiver module

receptively. Please note that the ground/ black pin is on the most left of this port, and the

most right pin marked with white should not be connected.
