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.

7. About UFHM-IFB (Optional)
Installing the UFHM-IFB (optional) on the UFM-15/18VDA and using with the UFM-30CTL
(available for separate purchase) enables you to view the status of the UFM-15/18VDA in a web
browser. See UFM-30CTL Operation Manual for details.
IMPORTANT
Before installing the UFHM-IFB on the UFM-15/18VDA, make sure that the dipswitch
settings on the UFHM-IFB are configured. Otherwise, the system may not operate
properly. If your UFHM-IFB is installed at the factory, the dipswitch settings are factory
configured.

7-1. Installing UFHM-IFB (Optional)
If you purchased the UFHM-IFB separately, first mount the UFHM-IFB on the UFM-15/18VDA
front module as described in the figures in this section and install it to the universal frame.
NOTE
The UFHM-IFB cannot be used with the UF-106A universal frame.
1) Remove the six screws on the UFM-15/18VDA front module (marked with white circles) and
remove the shield board.
(2)
(1)

12
2) Set the supplied four spacers on the UFM-15/18VDA (circled in a white rectangle) and
secure them from the backside of the card, using the supplied screws.
3) Return the removed shield board to the original position and secure it with the six screws
removed in step 1).
4) With careful attention paid to the connector positions, mount the UFHM-IFB on the
UFM-15/18VDA front module.
5) Secure the UFHM-IFB using the supplied four screws (marked with white circles).
*If your UFHM-IFB is already installed at the factory, these steps are not necessary.
