AGD340 command and diagnostic reference
Use the AGD340 serial command set to check identity, configuration and self-test information without bypassing the approved calibration process.
Connection settings
The later TAN18 source gives a default RS422 setting of 115200 baud, 8 data bits, no parity, 1 stop bit and no flow control. At boot, the radar reports its firmware and the operating baud rate at 115200 before switching to a stored higher rate. Confirm the exact build because earlier material describes 921600 as the normal operating rate.

Diagnostic limits
- Use diagnostic mode only where the communications link has enough bandwidth for the additional messages.
- A failed hardware self-test can stop the analogue-to-digital converter and leave the radar inactive. Record the error and contact AGD Technical Support.
- On revised CB-206 issue 14 hardware with MI-099-2 bootloader support, the *VN command no longer returns a unique flash identifier.
- Do not use factory or firmware-loading commands unless the work is covered by an approved service procedure.
