Rear Panel Connectors
To monitor video from these inputs, set the following:
• The Video Source select button to SDI,
• The SDI Input select button to SDI input either (In 1 or 
In 2
), and
• The 
SDI Group select button to the SDI Group of choice (1, 
2, 3, or 4).
To monitor audio (only) from these inputs, set the following:
• The Audio Source select button to SDI,
• The SDI Input select button input either (In 1 or In 2), and
• The SDI Group select button to the SDI Group of choice 
(1, 2, 3, or 4).
Even if SDI is not selected for monitoring through the unit, you can 
still select the SDI input (In 1 or In 2) and use the re-clocked SDI 
Output
 connector and CVBS Converted Video Output (from an 
SDI input) Connector regardless of other settings. This feature 
enables processing of the SDI signal independent of the unit’s other 
monitoring functions.
• SDI Out (BNC): The output BNC connector outputs a re-clocked 
HD/SD-SDI signal derived from the selected HD/SD-SDI input. 
This output functions regardless of other selection settings enabling 
output of the re-clocked HD/SD-SDI signal independent of the 
unit’s other monitoring functions (as long as a valid HD/SD-SDI 
signal is present at the input).
• (Optional) Unbalanced AES Out from SDI (HD-15): Unbalanced 
AES signals de-embedded from the selected SDI input are output 
from this HD-15 connector. See Figure 1–3 on page 19 for the 
pin-out for this connector. 
Note:
You can request the optional Unbalanced AES Out 
from SDI HD-15 connector instead of the Balanced 
AES Out from SDI DB-25
 connector at the time you 
place your order.
