RS-485 Connector Definition
The dome camera uses the RS-485 interface to communicate with a connected control device. Connect a control keyboard to the
speed dome using the terminal block. OpenEye recommends using CAT 5 cables for RS-485 communication with a maximum length
of 4000 feet (1219 meters) for 24-gauge wire. If the total cable length exceeds 4000 feet, use a repeater to maintain the signals.
Refer to the table below for pin definition and wiring.
