specifically recommend the specified relays since any “delay before break” time
delay relay meeting similar requirements may be used.
Note: Digital input 7 in Figure 21 and Figure 22 is used to monitor the status of
the power disconnect device. The installer must configure an event to
immediately shut down the DVR when Digital Input 7 deactivates. Refer to “Alarm
events
” on page 57 for more information on setting up events.
J2 audio and status connections
The MobileView PENTA provides two audio inputs and two status outputs on the
eight-terminal Phoenix connector labeled J2 (see Figure 23 below). More
information on the connection of specific terminals to optional hardware devices
can be found in Chapter 5
“Optional hardware installation” on page 67.
The J2 connector uses retaining screws to ensure that it does not disconnect
during operation. By design, the connector is easily removed if the retaining
screws are fully disengaged and a slight force perpendicular to the connector is
applied. Ensure that the retaining screws are fully engaged or unwanted
disconnection may occur.

Audio connections
The MobileView PENTA supports two channels of audio recording on line level
inputs. Each audio channel is one half of a stereo input. Audio input 1 is the left
channel and audio input 2 is the right channel. During playback, filtering between
the audio inputs is accomplished using the balance tool on the playback
computer.
See “Installing a microphone” on page 76 for more information on connecting a
microphone to the DVR in both single and dual channel configurations.
