b Terminate settings
This unit is equipped with camera A/B communication terminals and a video communication
terminal. When performing communication operations, connecting multiple models to the same loop
from each communication terminal will cause the data to reflect at both ends, affecting other data
and preventing proper data transmission to each piece of equipment.
Terminate settings refer to enabling proper communication by turning ON the terminate switch
provided on equipment connected at both ends of multiple connected units, and turning OFF the
terminate switch on the connected units in between.
Dipswitches (SW) 2 to 4 on the rear panel are
the terminate setting switches.
• SW1: For selecting PC software operation
or normal operation
• SW2: For terminate setting on camera
communication terminal A
• SW3: For terminate setting on camera
communication terminal B
• SW4: For terminate setting for video
