bTerminate 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
