1 CAT control using CI-V commands

CI-V (Computer Interface, version V) was introduced by ICOM® and is used for CAT control. The Xiegu X6200 uses a subset of the standard CI-V CAT instruction set to remotely control the transceiver and configure specific radio parameters. PC programs can use these instructions to extract data (e.g., frequency, mode) or control the radio during data transmission.

The USB-C type socket labeled 'DEV' on the right-hand side of the Xiegu X6200 connects the radio to a PC as a USB device using the provided USB-A to USB-C cable.

The Xiegu X6200 provides two serial interfaces via the CH342 chip. If the CH342 driver is not automatically installed, it needs to be installed manually or via the host OS driver tool from the Internet.

Ports (COM & LPT):

USB-Enhanced-SERIAL-A CH342 (COM7)
USB-Enhanced-SERIAL-B CH342 (COM8)

Both virtual serial ports can communicate at up to 115200 bps, 8 data bits, no parity, and one stop bit. SERIAL-A is used for terminal access, while SERIAL-B is used for CAT control at a speed of 19.200 bps.

Notes:

If your computer program selects a different radio make/model compatible with CI-V instructions, some instructions may not be responded to by the Xiegu X6200.
The following tables are based on firmware V1.0.6. Other firmware versions may have slight differences in supported CI-V commands.
The preamble for all commands is (in HEX) FE FE A4 00, with A4 being the target address of the Xiegu X6200 and 00 being the target address of the PC. The end character is FD.

Example: Sending FE FE A4 00 03 FD to get the active VFO frequency will return FE FE 00 A4 03 60 23 00 21 00 FD for 21.002.360 kHz.

3 CI-V Scout

For digital mode operation utilizing CI-V commands for remote 'CAT'-control, the program 'CI-V Scout' by Seth Cohen is recommended. It is a free Windows-based tool for testing CI-V communications with radios that use the CI-V protocol, such as the Xiegu X6200.

To use CI-V Scout, connect the supplied USB-cable between the Xiegu X6200 DEV port and your PC. Set up CI-V Scout to use the COM port corresponding to SERIAL-B of the Xiegu X6200 at a baud rate of 19200bps. You can check the correct port in the Windows device manager.

CI-V Scout allows sending single commands, including subcommands and data, to the Xiegu X6200. It also supports scripted macros created in advance or saved individually within the program.

Radioddity appreciates customer feedback. If any errors are found in the Xiegu X6200 firmware or this documentation, or if details are missing, please contact support@radioddity.com. Firmware updates for the Xiegu X6200 are generally free. Using non-Xiegu firmware is strongly discouraged and may invalidate the warranty.
