Unit connectors

Bus Connector - These are the physical interfaces to the video encoder rack, providing power,

network, RS-485 and the I/O connections.

Control Button - This button is used to reset the video encoder to the factory default settings. See

page 18.

Reset Button - This button disconnects and reconnects power to the video encoder. See page 18.

Audio in/out - 3.5 mm jack combined for both input and output. The jacks are compatible with

M6 x 0.5 threaded locking collars.

• In: Balanced or unbalanced input for a mono microphone or line signal.

• Out: Audio out (line level), that can be connected to a public address (PA) system or an

active speaker with built-in amplifier. A stereo connector must be used.

For best audio quality and when using long cables, use a balanced microphone and shielded cables.

For a more secure connection, threaded audio connectors are recommended. In this case, the audio

mounting nut will need to be removed see

Hardware overview,

on page 6.

Video Inputs - The AXIS Q7414 supports 4 video sources. Each video input is terminated using a

coax/BNC connector. Physical connections made using 75 Ohm coaxial video cable have a

recommended maximum length of 800 feet (250 meters).

Note:

AXIS Q7414 does not have physical line termination DIP switches. If the product is to be con-

nected in parallel with other equipment, 75 Ohm video terminations can be enabled/disabled on

each input in the product's web pages at Video & Audio > Video Input > Video termination.
