Installation
Cabling
Input
The SD video stream is connected to the looping input BNC at J9 or J10. If
not looping the signal to other equipment, terminate the unused connector
into 75
Ω .
Outputs
The 8920DMX provides four SD output streams—J1 through J4. The desti-
nation equipment should have a 75
Ω input impedance or loop through
inputs that are terminated into 75 Ω .
For unbalanced AES/EBU audio outputs, connect cables to BNCs J5 and J6.
For applications requiring balanced audio outputs, use the terminal post
adapter shown in
Figure 3 to connect up to two balanced AES/EBU output
cables. The adapter mounts on the plus and minus BNC pairs J5/J7 and
J6/J8. This adapter ships with the 8920DMX-110 model or can be ordered
separately if required.
Note Jumpers JP12 – JP15 on the module circuit board must be set for the correct
audio output impedance (balanced 110
Ω or un balanced 75 Ω ). Refer to
Audio Output Impedance on page 14 .
