connecting to an external device

The SPC-7000 network controller can be used by connecting to cameras, DVR, and

other external devices.

TO CONNECT A RS-485/422 DEVICE

You can control a PTZ camera and DVR that support RS-485/422 communication with the controller.

1. Connect the rear PORT 1 with RS-485 port of the PTZ camera or DVR.

According to the external device connected, select RS-485 (Half Duplex) or RS-422 (Full Duplex)
