iSecus SDR Counter UAV Digital Module User Manual
Overview
SDR CounterUAV Digital Module is a general-purpose digital RF module based on software radio architecture, which contains two major parts: digital source and power amplifier unit. The digital source part of the FPGA can generate UAV jamming code signals with different digital modulation methods, which are converted into RF signals through the SDR platform and amplified by the power amplifier. The digital source meets the frequency range of 100MHz~6000MHz output, the bandwidth of 200MHz arbitrary configuration, with accurate frequency characteristics. The module can select the corresponding digital modulation jamming code for different UAV types to achieve the best counter effect, supporting ELRS, Crossfire, Flysky, Ocusync, Lightbridge, skyleas and other common protocols for effective jamming. Small form factor, flexible port, simple integration.

Basic Functions
After the module is powered on, wait for the initialization of the module to be completed, and after the Ready signal goes high, the amplifier switch can be controlled through the PA_EN pin.
The module has two control ports, IO enable port and RS-422 communication port; IO enable control is simple and convenient for users to integrate and use; RS-422 port in addition to controlling the amplifier.Besides there is access to the module temperature, current and other state parameters, as well as configuration of the digital interference code, so that the product is more flexible and more intelligent. Each module has 2 RS-422 ports, which are used to connect the modules in series and reduce the ports and wiring harness.

Software Ports
- Port selection: Connected to the serial port after the port appears on the left side of the red indicator dots.
- Jamming code selection: You can select different interference codes corresponding to jam with different targets (optional when the module communication is normal, otherwise the option is blank), the relevant instructions in Table 5.
- Gain Selection: Support 1~15 gain selections, power-on default is the highest 15, step ≤ 1dB, after modifying the gain, press the Configure button to take effect.
- Configuration button: Send the current gain configuration to the module.
- Jamming On button: Turn on jamming.

Caveats
- The frequency range of the output antenna should be the same as the frequency range of the module, and the non-correspondence of the frequency will lead to the damage of the module.
- The power supply wiring should meet the current requirements and be connected reliably.
- When the module is used, good heat dissipation should be ensured, so as to avoid overheating and causing damage to the module.
- After purchasing the module, please ask for the RS-422 protocol from the professional sales.
