GPIOs
Three rear-panel
GPO
(General Purpose Output) terminals
present alarm “tally” connections for remote indication of
program audio loss. The plastic connector body may be
unplugged from the chassis to make connection easier and
for quick disconnect.
GPOs are programmed
from the
Setup
/
Outputs
/
General Purpose Outputs
menu. The
Polarity:
of
each
Output:
1
,
2
or
3
may
be programmed as an
Active Ground
(the terminal goes to
ground for an alarm) or
Active Open
(the terminal normally
sits at ground and opens on an alarm).
Type:
may be as-
signed to
Analog Audio Loss
,
Digital Audio Loss
or
Stream Audio
Loss
.
None
inhibits the alarm terminal closure or open.
Alarms have the programmable parameters explained on
Page 11.
Alarm GPO ‘tally’ outputs are the collectors of NPN transis-
tors that saturate to ground. Up to 100mA may be ‘sunk’ by
each of these outputs to operate relays or LED indicators
using an external voltage source up to 24VDC. The negative
side of the external power source must be returned to the
GND
(Ground) terminal on the rear panel; a 10mA current-
limited
+5V
source is provided as a convenience.
The three
GPI
terminals have no application at present, but
have been included for future use.
The Network Port
The rear-panel RJ-45 jack connects with your local network
(LAN), and from there through your network router to the
Internet. A network connection is required for the Web in-
terface, for 2-way audio streaming, and for SNMP functions.
+12VDC Power I/O
Two paralleled ‘coaxial’ connecters allow ‘daisy-chaining’
two half-rack units that share a common rack adapter. A
short ‘pigtail’ cable is provided with each rack adapter for
power loop-through.

The NOVIA 236 draws 240mA. Check the rating on the la-
bel of the power supply to make sure it has capacity for the
modules it must support.
These power connectors are not a locking type. A Ty-Wrap®
will secure power cables to the plastic anchor above the
connectors if this becomes a problem.
Password Protection
You may protect NOVIA 236 settings with a password,
which thereafter must be entered before any subsequent
changes can be made. Either the same or separate pass-
words may be assigned to lock out the front-panel and Web
interface access.
From the Main Menu, navigate to
Admin/Securit
y. Enter either
or both boxes to manually enter a password for
Front Panel:
or
Webpages:
. Highlight
Save
and push the knob to set the
password in memory. Once the password is saved, the
Now
Playing
screen will be the only menu item available.
Press the
Back
button to sign-in. You will be prompted to
enter the password before any menu can be accessed and
any adjustments made. Similarly, the
Webpages:
password
must be entered on a Web-enabled computer or other con-
nected device.
To recover a lost password, you must perform a “hard re-
set.” This deletes not only the passwords, but will also re-
turn the NOVIA 236 to factory-default values.
All User set-
tings and presets will be lost!
Initiate a hard reset by holding
down the
Back
button as you power-cycle the unit (discon-
nect and then reconnect power). Always keep an up-to-date
Hardware Profile to back up your settings (see Page 29).
Miscellaneous Administration Menus
The
Admin/Display
menu offers a
Brightness
adjustment for
the OLED menu screen. We don’t recommend a higher set-
ting than the 60% default setting, as it doesn’t look that
much brighter and may shorten the life of the display.
Timeout
sets the interval between the last use of the knob
and the screen going
Dim
(dim) or
Dim
(dark). You can
set this between
5 min
and
60 min
. Test the screen-saver by
holding-down the
Back
button.
