3.3.1 Auxiliary Port Mode Setting

The default setting of the mode setting is “Not Connected”. The Auxiliary Voltage Port on

the OSD main board will be disabled, and there will not be any voltage or RSSI of the RC

link information displayed on the lower-left of the screen. If this option is set to the “Video”

mode, the Auxiliary Voltage Port can be used to measure the real time voltage of any

auxiliary battery pack, and the voltage will be displayed on the lower-left screen above the

power battery pack information as per Figure 2.2 as described in chapter 2.5.1. In general,

this port is used to monitor the voltage of the video system battery, as it is normally a

separated battery pack other than the main power battery pack. Beside the above, the

mode of this port also can be set to “RSSI” mode. Now the RSSI of the RC link is shown

on the lower-left screen as per Figure 2.3 as described in chapter 2.5.1.

3.3.2 Auxiliary Port Voltage

The real time detected voltage value of the connected voltage source on the auxiliary port

is displayed on the lower-left screen above the power battery information. If the “Video”

mode is selected, it will be shown with “Video:” and the voltage value behind it. If the

“RSSI” mode is selected, it will be shown with “RSSI:” and the voltage value behind it.

3.3.3 Auxiliary Port Voltage Calibration

You may calibrate the auxiliary port voltage reading by setting the voltage offset in this

option. It is always recommended to connect an accurate multi-meter to perform this

calibration. Connect a battery onto this port, and parallel a voltage meter with this battery,

adjust the setting of the voltage offset, let the voltage reading at the lower left screen (as

described in chapter 3.3.2) to be the same as your voltage meter.

3.3.4 Low Signal Voltage Setting for RSSI

This setting is only applicable when the auxiliary port mode is set to the “RSSI” mode. This

value is set according to the RC receiver RSSI output voltage when transmitter signal level
