System Connection and Power Up

The Luxsar
The following sections will describe basic connections in a surveillance system.
4.1

Connecting RS-485 Cables

To operate dome cameras, a control keyboard (or other control device, e.g. DVR)
is needed to communicate all devices via RS-485 interface. The CAT 5
(Shielded twisted pairs) cables are recommended for RS-485 communication;
maximum cable length for over 24-gauge wire is 4000 feet (1219 meters). If the
total cable length is over 4000 feet, using a repeater to enlarge the signals is
recommended.
Terminal block is designed for long distance installation. Users can construct a
RS-485 network through the terminal block located on the rear panel of the
control keyboard. Detailed pin definition can be found on the terminal block.
