‘IRS’ Enable / Disable Front Panel IR Sensor
Setting the ‘IRS’ bit to ‘0’, disables the IR sensor on the front panel. This has no affect on IR signals
being received through the rear panel IR jack. This is useful in preventing stray IR from affecting the
ClarityHD8x8 when only the rear IR jack is being used.
‘IRJ’ Enable / Disable Rear Panel IR Jack
Setting the ‘IRJ’ bit to ‘0’, disables the IR jack on the rear panel. This has no affect on IR signals being
received through the front panel IR sensor. The best way to disable the IR jack is to simply unplug
whatever it is you have plugged into it.
It’s not usually a problem having both the front panel IR sensor and the Rear panel IR jack enabled. IR
will be accepted from either. If both the front panel IR sensor, and the rear panel IR jack received sig-
nals simultaneously, the rear panel jack will have priority.
If a controller is constantly sending data to the rear panel jack, this can effectively jam the front panel
sensor. Setting this bit to ‘0’ will disable the rear panel jack and allow the front panel sensor to operate
normally. Though once again, it might be better to just unplug the rear panel IR jack if it’s not going to
be used.
‘SS’ Save Default Power On Settings
When all power is lost to the ClarityHD8x8 (for instance the power cord is unplugged), the current set-
tings will be lost. When power is restored all settings will be set to their initial values. This command
allows you to change those initial values.
To use this command, the ClarityHD8x8 should be set to the values that are to be used as the initial val-
ues.
Once the current settings are in place, this command is issued to save the current settings as the initial
values.
This command uses a bitmapped parameter to indicate which values are to be saved. A bit set to ‘1’
indicates the associated setting should be saved, a bit set to ‘0’ indicates the setting should not be saved
and the previously saved setting will remain unchanged.
Command formats:
^SS
settings$
Set the enable bits to ‘settings’
Response String:
There is no response string to the SS command, this command is write only.
Where ‘settings’ is a bitmapped parameter defined as:
Bit-0
- Save zone input/output mappings, and power state
Bit-1
- Save switching delay times
Bit-2
- Save LED levels and mode
Bit-3
- Save control settings (the XS command settings)
Bit-5
- Save IP parameters
Bit-15
- Save HDMI settings: EDID and HDCP caches, HDCP key counts, and the EDID lock state.
Note: The ClarityHD8x8 must be powered on before sending the “Save HDMI settings” (Bit-15).
All other bits are reserved and should be set to 0 when issuing this command.
