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.
6.1

Establishing Control of the Camera

The MIC550 Classic camera supports two communication protocols (Biphase and RS-485),
Bosch, Pelco D and P, and Forward Vision (keyboard) controller protocols that allow you to
send commands to the camera and to receive information from the camera.
6.1.1

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.
Shielded 2-wire, half-duplex, multi-drop, 5000 ft. cable limit
Biphase is the standard Bosch protocol used to send Pan/Tilt/Zoom control over 2-wire
shielded twisted pair (STP) terminated with a 100 Ω terminal resistor. Biphase connections
require a MIC-BP3 or a MIC-BP4 Biphase converter (sold separately).
CAUTION!
The Biphase shield must be connected to the head end only.

6.1.2

Establishing Control of the Camera via RS-485 Protocol

NOTICE!
In Pelco controller protocol, RS-485 is the only communication protocol that the MIC-550
supports. It does not transmit responses back to the controller.
2-wire (shielded), half-duplex, differential, multi-drop (32 nodes), 4000 ft cable limit
RS-485 is capable of controlling a true multi-drop network and is specified for up to 32 drivers
and 32 receivers on a single 2-wire bus. The camera uses the 2-wire mode, although RS-485
can be connected in a 2- or 4-wire mode.
NOTICE!
The wire shield must be tied to signal at both ends, if 2-wire twisted pair is used. After
connecting the wires for RS-485 operation, ensure that the slide switch on the main board to
the camera head is positioned toward the LEDs (default).
