Assigning Input Signals to Connectors
Before inputting signals to the BKM-48X, you must
specify the type and format of the signal that will be
input to each connector. To assign input signals to
each connector, use the on-screen INPUT
CONFIGURATION menu of your video monitor.
For information about using the INPUT CONFIGURATION
menu, refer to the manual of your video monitor.

Functions
Analog Input and Output Signal
Connectors
The BKM-48X is equipped with input and output
connectors for two signal paths. You can input Y/P
B
/P
R
or GBR signals to the input connectors.
Floating System
Each input conector can be selected to either floating
or grounded mode by the switches on the board (SW1
to SW6, shown in the figure below).
To set the grounded mode, insert the jumper-pins into
the ON slot and the center slot. To set the floating
mode, insert the jumper-pins into the OFF slot and the
center slot.
The factory preset is grounded mode.
Floating mode is useful for rejecting common mode
noise.
Using the Input and Output
Connectors
For information about installing the BKM-48X in a video
monitor input option slot, see “Installing into Video
Monitors” (page 7 (E)).
