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.

Infrared illumination and connection

When using infrared illumination, please make sure to adjust the focal point of the lens
in color mode.

If excessive infrared illumination causes the phenomenon above, set the picture mode
at B/W using the BW Fix terminal.

RS485 communication terminal (with communication function)
The RS485 communication function enables remote operation of the OSD function.
* For initial settings of camera for RS485 communication, please see “RS485
Menu” of the separate “OSD Operation Manual.”

While connecting a shielded twisted pair cable to a
terminal [B/W Fix terminal, Communication terminal
(AWG 16-30)], peel off the cable by 5 mm from the
end.

Termination resistance switch (with communication function)
During the RS485 communication connection, turn on the termination resistance
switch of the camera connected at the end of the cable, and turn off all other
switches. Adjust the characteristic impedance of the cable used to the same level
as that of the termination resistance (120
Ω
).
