Unit Connectors - Axis Q1755 User Manual

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.
