Reference Connection
To connect video reference:
1.
Connect a stable analog reference signal (such as Black Burst)
from your house sync generator to the left-hand Reference
connector.
Note
The house sync generator must feed the same reference to all devices in
your Lightning system.
2.
If Lightning is the last device in your reference loop, terminate the
right-hand Reference connector with a 75-ohm terminator as
shown below.
