7.9.6.1. Port Parameters and Settings
Supported Boards:
▪ MX-DVII-HDCP-IB; MXD-UMX-IB
Description: Query or set the DVI-I input port related parameters.
Querying the Parameters 1. (When Analog Signal is Present)
Format
Command {:DVII#<in>@<S/C/A>I=?}
Response (DVII#<in>@<S/C/A>I=<src>;<sig_type>;
<aud>;<hdcp>;<ps>;<video>;<timings_1>;
<timings_2>;<res>;)CrLf
Explanation: The actual settings are in the response; see the legend for the details. The first six parameter
types are always the same in the case of analog and digital signal.
Querying the Parameters 2. (When Digital Signal is Present)
Format
Command {:DVII#<in>@<S/C/A>I=?}
Response (DVII#<in>@<S/C/A>I=<src>;<sig_type>;
<aud>;<hdcp>;<ps>;<video>;<color>;<res>;
<a_type>;<a_samp>;<a_ch>;)CrLf
Explanation: The actual settings are in the response; see the legend for the details. The first six parameter
types are always the same in the case of analog and digital signal. <a_type>, <a_samp>, and <a_ch>
parameters exist only when the incoming signal type is HDMI.
Setting the Parameters
Format
Command {:DVII#<in>@<S/C/A>I=<src>;<sig_type>;
<aud>;<hdcp>;}
Response (DVII#<in>@<S/C/A>I=<src>;<sig_type>;
<aud>;<hdcp>;<ps>;<video>;<color>;<res>;
<a_type>;<a_samp>;<a_ch>;)CrLf
Explanation: The new settings are in the response; see the legend for the details. The signal type is changed
to DVI and the HDCP is set to disabled. The other parameters are left unchanged. Use the 'x' character to
keep the actual value of a parameter.

Legend (the first six common parameters)
Identifier Parameter Description
R = analog RGB
Y = analog YUV
<src> Source type A = automatic analog
D = digital interface (HDMI or YPbPr)
S = automatic input selection
A = auto (if the port is not HDMI-compatible the type will be DVI)
Signal type D = DVI (no audio)
<sig_type>
sent to the crosspoint H = if HDMI signal is present the type will be HDMI. If analog or
DVI signal is present the type will be DVI.
0 = no audio
<audio> Audio signal presence D = embedded audio (from HDMI)
A = audio from the add-on board (if exists)
0 = HDCP is disabled
<hdcp> HDCP setting
1 = HDCP is enabled
bit 3
Port status, binary data
<ps> represented in HDX
reserved
format (read-only)
H = HDMI signal
D = DVI signal
The deteced signal type
<video> R = RGBHV (analog signal with HV sync)
(read-only)
C = component (analog signal with embedded HV sync)
- = no video signal, no sync detected
Legend Addition (Analog Signal)
Identifier Parameter Description
<timings_1>
Timing parameters
<timings_2>
The name of the
<res>
resolution (string)

The name of the
<res> <width>x<height>p<refr_rate>, e.g. 1600x1200p60
resolution (string)
* If bit 0, bit 1, and bit 2 are 0, the color depth is 24 bit/pixel. If bit 3 and bit 4 are 0, the color space is RGB.
E.g. 00 = RGB color space at 24 bit/pixel color depth.
Parameter Values
bit 2 bit 1 bit 0
0 = not protected 0 = 5V not detected
1 = HDCP-protected 1 = 5V detected
