2.4 Setting Dome Camera Termination and Fail Safe Bias
The device which is connected at end of line, whether it is a dome camera or keyboard controller,
must have the cable for communication terminated by setting the appropriate DIP switch.
Without proper termination, there is potential for control signal errors. Total length of the cable
for communication should not exceed 1.2 km.

Figure 4 – Setting Dome Camera Termination
When you don’t use our keyboard, the other keyboard may not control our dome. At that time
you set the DIP switch 2 and 3 of the SW1 to ON to add the external fail safe network of the RS-
485 line at the nearest dome only from the keyboard.
2.5 Setting Dome Camera Address (ID)
To prevent damage, each dome camera must have a unique address (ID). When installing
multiple dome cameras using a multiplexer, it is suggested that the dome camera address match
the multiplexer port number.
Example: Port 1 = Dome 1, Port 2 = Dome 2 … Port 16 = Dome 16. If more than 16 dome
cameras are installed using two or more multiplexers, ID of the dome camera should be ID of
MUX x No. of camera IN. (e.g. multiplexer ID= n, Camera IN= m then ID of Dome =16x(n-1)+m )

When you set the dome camera address (ID) over 99, press 2 , 5 , 0 , and PRST keys of the
keyboard. Then the FACTORY SETUP displays as below.
1. Select the DOME ID option by using the Joystick .
2. Change the number of the DOME ID by using the Joystick to the right.
Eg.) DOME ID:01XX, (XX means the number of the DIP switch): DOME ID=100+XX
When the DIP switch is 99, DOME ID=199
3. Select Save and Exit by pushing the Joystick to the right. Press ESC to exit the Preset menu
