B/W Fix terminal/Mode Selection terminal

This terminal can be used as a B/W Fix terminal and also as a Mode Selection

terminal that enables the dynamic switching of OSD settings. The mode selection

setting needs to be adjusted beforehand on the OSD setting screen. The picture

mode can be fixed at B/W by shorting the two contacts on the B/W Fix terminal.

Fixing the picture mode at B/W can prevent the picture from having a phenome-

non in which continuous switching occurs between the color mode and B/W mode

under infrared illumination. The Mode Selection terminal allows switching between

Profile 1/Profile 2 selected on the OSD screen.
