OutputStatus
Event-driven API command. Feedback indicates if a sink device is present, based on the state of both the HDMI HPD
and TMDS signals. If a sink is detected on an output, then a 1 will be returned. Outputs with no source connected
will return a 0.
Note that the number of 1 and 0 values returned, is dependent upon the number of outputs on the unit. For example,
the AT-UHD-CAT-4 has one HDMI output and four HDBaseT outputs, for a total of five outputs. Therefore, if all
outputs were connected to a sink device, then the OutputStatus command would be formatted as:
OutputStatus 11111

If the local HDMI display is disconnected to an AT-UHD-CAT-8, and all All HDBT ports are used, then the following is
true:
a. The control system, using either RS-232 or Telnet, will receive
OutputStatus 111111110
. The last digit in
the
output
always
indicates the HDMI output. HDBaseT outputs are read from left-to-right, with the first
HDBaseT output occupying the left-most digit in the output.
b. Reconnecting the display will return
OutputStatus 111111111
.
If all displays are powered-off using CEC, the following is true:
a. The control system, using either RS-232 or Telnet, will receive
OutputStatus 000000000
. Note that some
displays may only mute video, while the HDMI-HPD line is kept high.
