Introduction
GSOC universal controller is a terminal product used for external extension control of
X5105 and G90/G90S. It can be used for radio host control. More importantly, it can
be extended into many advanced functions and usages, improving the device
maneuverability and playability.
GSOC consists of a baseband processing unit and an SDR receiving unit, which is
capable of receiving and processing IF signals and IQ signals and finally displaying
relevant contents (such as frequency spectrum, waterfall plot and demodulation
information) after 24bit-ADC sampling and processing. GSOC is featured by
diversified external interfaces and strong extended functions, which is capable of
satisfying the present demands for network operation and Bluetooth control.
Certainly, you can also operate all radio functions directly through the operating
mode of touch control. GSOC allows you the experience of large screen and wide
frequency spectrum and to keep everything under control!
Extension of spectrum and waterfall functions
Common advanced function extension, such as digital noise reduction, digital
filter, etc.
7" color touch LCD display
Automatic voice call and preset message storage & sending
Support keyboard and mouse control
Support external Bluetooth WIFI adapter
Dual-core application processor, large memory
Support full functional control of X5105, G90 and G90S
Please read this manual carefully for a better experience and full understanding on
operation of the GSOC.

Note:
◆The plug in the external speaker/earphone is a 2-core monophonic connector,
which will cause a short circuit of the audio signal, resulting in silence.
◆Direct use of the 2-core to 3-core connector can also cause short-circuit of the
audio signal, resulting in silence.

Power Supply Wiring
13.8V external DC power supply is available for GSOC controller. Attached power
lines can be used to connect to equipment and DC power supply.
DC power supply shall be connected in strict accordance with following figure to
avoid reverse polarity connection.
White line shall be connected with the positive pole of power supply and
metal-shielded line shall be connected with negative pole of power supply.
■EMC magnet ring can be applied on power lines to prevent external
disturbance from entering the controller via power lines and radio-frequency
interference in the equipment from radiating externally via power lines when
external power supply is adopted. Magnet ring shall be installed at the side closing to
the controller.
◆Polarity of power lines shall be carefully inspected to avoid reverse polarity
connection when external power supply is adopted.
◆Reverse connection of power may cause severe damage to the controller.
