Here is how I setup the loop-back test:
1) Loaded ADAT A-B routing configuration
2) Set Program A to Mute
3) Set clock source to internal 48 kHz
4) Set all Main Inputs to
, then set set Main Inputs IN 1 to ADAT in 1
5) Set all DSP A i/p routing to
6) Set all DSP B i/p routing to
7) Set all Main Outputs (Analog) to
, then set Main Outputs (Analog) ANA1 to DSP B out 1 +
(so I could hear the signal)
8) Set all Main Outputs (Digital) to
9) Set all ADAT Outputs to
, then set ADAT Outputs out1 to Main Out 1
10) Set all AES Outputs to
11) Set all Firewire 1 Outputs to
12) Set all Firewire 2 Outputs to
13) Plugged one lightpipe TOSLink cable from the Out port to the In port
14) Powered the H8000FW off, then on
15) Set Program B to Oscillator
Result: A signal shows up on all 8 channels of the Main Output block, and on channel 1 of the Output block, but no signal shows up on the Input block (I don't expect one to show up on the Main input block due to the way I have routed the signals.)
Do you think this is a valid test to determine if there is a hardware failure in the ADAT Out port?
