■Mode Switch

RS485 interface is used to communicate between this unit and the PS·Data compatible system device. In this case, it is neces- sary to terminate both devices on both ends of the RS485 connection.

The settings of the mode switch will be different depending on whether this unit is used as a receiver or a controller.

When an RS 485 camera is connected to this unit, it is necessary to terminate both devices on both ends of the connection.
