The Broadcast Pix Granite system can also control Hitachi cameras with the Eagle Pan/Tilt heads and protocol.
Up to 9 Cameras, with 32 presets each, are connected to the server using a serial RS-485 connection, which has
a maximum length of 1,200 meters (4,000 feet). A DB 9-pin RS-232 to screw terminal RS-485 converter is
included, which plugs into the server in COM 1 or COM 2 and feeds a Multiplexer (or wire splice) that sends 5
wires to each camera head, 3 are for communication and 2 for power. All cameras connect to a multiplexer to
split power and communication to all your cameras. The Pan-Tilt heads, Multiplexer, power supplies and cables
are provided from Eagle.
