Select OK.

On the G-857 press OUTPUT, ENTER when this window opens.

If the download sequence does not happen this way, it is usually a problem with:

1. USB/RS-232 Adaptor not FTDI, or driver not installed.

3. BAUD RATE mismatch.

4. Faulty I/O Cable PN 16492-01.

5. Faulty Computer.

6. Faulty G-857 console.
