4.3 Precautions
Concerning the performance of the VD-1673
• Depending on the signals which are input to the VD-1673, it may not be possible to output the output
signals properly.
• It is not recommended that the VD-1673 be used at multiple stages.
Concerning the CONFIGURATION switches
• The reserve bits must be set to OFF without fail.
Concerning the CEC line
• CEC communication is possible only using the input port selected and the output port or ports selected.
(The CEC line for the input and output ports not selected is cut off.)
• While the switcher’s power is OFF, the CEC line for the input port and output port is cut off. (While the
power is OFF, CEC communication with the VD-1673 in between units on either side is not possible.)
Concerning the pre-emphasis level
• When the pre-emphasis level has been set to “3 dB” or “6 dB,” the TMDS characteristics will not satisfy
the ratings under the HDMI standard.
Concerning the “DISTRIBUTION” output mode
• The DDC and CEC signals among the HDMI signals take effect only for those output ports selected.
• If “DISTRIBUTION mode” has been selected when TMDS signals encoded using HDCP have been input,
the signals will be output normally only through the output ports selected.
