Set Front Panel Intensities
I<min><space><max>
Set the minimum and maximum front panel intensities.
Where:
<min>
= The minumum (dim) intensity level of the front panel LEDs (0-255).
<max>
= The maximum (bright) intensity level of the front panel LEDs (1-255).
Minimum intensity must be less than the maximum intensity.
If <min> is set to zero (LEDs blanked) the DIM Lamp Mode setting ‘L0’ will no longer be available. When attempting
to set the Lamp Mode to DIM, BRIGHT will be used instead. This keeps the user from inadvertantly turning off the
front panel LEDs by setting the DIM mode using the IR remote. The proper way to turn off the front panel is by issuing
the ‘L3’ command.

The ‘I’ command is only available on firmware versions 1.1 or later.
Control Bits
X<ControlBits>0<CR>
Where:
ControlBits =
Status control bits. This is a bitmapped value, given in decimal.
0
Reserved, always set to 0.
IR
0=Normal IR (default), 1=IR control disabled.
KB
0=Normal Keyboard (default), 1=Keyboard selection disabled.
AS
0=Auto-status off (Polled Mode), 1=Auto-status transmissions enabled.
X?<CR>
Request current ControlBits setting
The HDS4.2 can be set to send a status message when any of the following occur (outside of an RS-232 command):
• A new channel is selected.
Sends a Channel Status string
• The power state changes.
Sends a Power Status string
• The state of the lamp intensity changes.
Sends a Lamp Status string
• A button is pressed on the front panel.
Sends a Button Status string (Note 1)
The responses are identical to the responses you receive when you request the information using the “?” parameter
for each of the above commands.
for each of the above commands.
When ‘X0<CR>’ is issued, these above actions will not automatically be sent, but will be buffered.
When ‘X1<CR>’ is issued, any pending status messages will be sent, and from then on, any of the above actions
will cause a status message to be immediately sent.
will cause a status message to be immediately sent.
Status changes made through the RS-232 will not cause the above status strings to be automatically sent. For in-
stance, a button press will send a Channel Status string, an IR remote Channel change will send a Channel Status
string, however the command ‘C+<CR>’ will only be followed by the ‘+<CR><LF>’ acknowledgement string.

See the section on HDS4.2 status strings for the syntax of the status strings.
Note 1: The Button Status string is only sent automatically when the HDS4.2 front panel is disabled and the ’AS’
bit is set to ‘0’.
Note 2: The ‘IR’ and ‘KB’ bits are only available in firmware version 1.1 or later.
Query Command Status

If the command ‘X0<CR>’ has been issued then command statuses will not be immediately sent but instead buff-
ered. This command returns a bitmap that indicates what statuses are buffered and need to be read.
