3. Connection
CAUTION
Turn all the power OFF before making connection.
Refer to figure below for connecting the UFM-15VDA/18VDA to other devices.
Note that before installing the UFM-15VDA/18VDA into the universal frame, you should thoroughly
read the operation manual for the Universal Frame (UF-106A or UF-112) where you will be
installing.
(1) OPERATE / BY-PASS mode
(2) Loopthrough mode
VIDEO IN is high impedance when in loopthrough mode. The last device in the chain should
be terminated with 75Ω.
