5	Getting Started
	Install and wire the camera according to the instructions in this manual and in the manuals
	that accompany the power supply and mounting devices. A typical system includes a
	keyboard, matrix switcher, monitor, and appropriate wiring connections. Refer to the
	individual product manuals for complete installation and setup instructions for each of the
	system components.
5.1	Establishing Control of the Camera
	The MIC612 supports two communication protocols (Biphase and RS-485), and both Bosch
	and Pelco D and P (keyboard) controller protocols that allow you to send commands to the
	camera and to receive information from the camera.
5.1.1	Establishing Control of the Camera via Biphase Protocol
	NOTICE!

Biphase protocol works only with Bosch controller protocol. It does not work with Pelco controller protocol.

Biphase is the standard Bosch protocol used to send Pan/Tilt/Zoom control data. Biphase connections require a MIC-BP3 or a MIC-BP4 Biphase converter (sold separately).
