When I poll the inputs over RS‑232 using the DACAD command, and the DAC’s display setting is “Display Auto Off”, the front panel display turns on for a few seconds on every poll. This does not happen when I poll the volume using the DACBK command.
As a result, the display appears to flash or blink periodically whenever input polling is active.
Please fix this behavior in the next firmware release.
I’m actually doing some work with the RS-232 commands right now. Can you tell me what product you have so I can check this?
Cascade
At the moment, there is no direct RS‑232 command that returns the current mute status. The only way to infer mute is indirectly via the volume (for example, when BK = 0), which is not reliable.
In addition, the Cascade clearly distinguishes between “volume = 0” and “mute on”
I have made both of these changes. They will be in the next firmware release. Please email me and I can send you a early release for testing if you would like.
The changes I made are:
A. It won’t wake up the display when requesting the current input.
B. Two new commands. Command to poll the volume (ignoring the mute status) “DACBO” and the command to poll the mute status “DACBP”. The RS232 table online has been updated.
Great, thanks a lot for adding this!
Both changes are exactly what I need for my control setup.
I’d be happy to test an early firmware — please send it over when convenient.
