LED1 unlit .0Test mode, or GS9023A in failure
LED1 lit The SDI audio signals (Ch 1/2) are input.
LED1 blink GS9023A operating normally
LED2 unlit
Either of the following four cases: (1) Test mode, (2) GS9020A in failure, (3) An SDI signal other than 525i/625i component
signal (270 Mbps) is being input, or (4) A copy-protected signal is being input.
LED2 lit
The SDI 525i/625i component signal is being input, and an EDH packet is embedded in the SDI input signal. Both GS9020A
and GS9025A are operating normally.
LED2 blink No SDI input. GS9020A is operating normally.
LED3 unlit When a transmitting machine is not connected: CS8414 in failure When a transmitting machine is connected: A consumer-
format signal is input.
LED3 lit A 48-kHz Fs AES/EBU signal is being input.
LED3 blink Either of two cases: (1) A professional-format signal other than mentioned above is being input, or (2) No AES/EBU input,
and CS8414 is operating normally.
