AXIS Q1755/-E - Unit connectors

Unit connectors

Network -

RJ-45 Ethernet connector. Supports PoE (Power over Ethernet, class 3). Using shielded cables is recommended.

Audio in -

3.5mm input for a mono microphone, or a line-in mono signal (left channel is used from a stereo signal).

Audio out -

3.5mm output for audio (line level), can be connected to a public address (PA) system or an active speaker with a

built-in amplifier. A pair of headphones can also be connected. A stereo connector must be used for audio out.

Video Out -

RCA connectors for component or composite video out.

• Component video out (Y/Pb/Pr) for HDTV video, e.g. an entrance camera connected

to an HDTV screen

• Composite video out (CVBS) - for easy installation using a video monitor. CVBS is

available for 2 minutes after pressing the button and should only be used during
installation.

RS-485/422 -

two 2-pin terminal blocks for RS-485/422 serial interface used to control auxiliary equipment, e.g. PT devices.

The RS-485/422 serial port can be configured as follows:

• Bidirectional RS-485 half-duplex port for data transmission using two wires, one combined

RX/TX pair.

• Bidirectional RS-485 full-duplex port for data transmission using four wires, one RX pair and

one TX pair.

• Unidirectional RS-422 port for transmitting or receiving data using two wires, RX- or TX pair.
• Bidirectional RS-422 full-duplex port for data transmission (point-to-point) using four wires,

one RX pair and one TX pair.

SD memory card slot -

SD and SDHC memory card can be used for local recording and removable storage.

Lens -

M37x0.75 mounting thread for optional lens adaptor, for example wide-angle adaptor, tele adaptor or lens filter.

Remove the existing lens cover and retain for future use. Attach the adaptor securely to the camera casing.

I/O terminal connector -

Used in applications for e.g. motion detection, event triggering and alarm

notifications. In addition to an auxiliary power and a GND pin, the AXIS Q1755/-E has 2 pins that can be
configured as either input or output. These pins provide the interface to:

• Transistor output - For connecting external devices such as relays and LEDs. Connected devices can

be activated by AXIS VAPIX API, output buttons on the

Live View

page or by an

Event Type

. The output will show as

active (shown under

Events > Port Status

) if the alarm device is activated.

• Digital input - An alarm input for connecting devices that can toggle between an open and closed circuit, for exam-

ple: PIRs, door/window contacts, glass break detectors, etc. When a signal is received the state changes and the input
becomes active (shown under Events > Port Status.)

Notes:

• The I/O connector on AXIS Q1755-E is connected to the housing electronics at delivery and will trigger an input port

event to indicate a fan or heater error when activated. See

Events,

on page 31, for information on how to set up an

event.

• For information on how to connect external devices, refer to the Installation Guide supplied with the product.
