Installation
Neets Sound Bar – SB2 is designed to be easily installed, in any convenient location. It can be mounted on the
wall beneath, or above a screen, or placed on a desk free standing.
To use the Sound Bar freestanding on a desk, simply unpack the unit, mount the adhesive feet, and it is ready
to go.
To use the Sound Bar on a wall use the included brackets, screws and when necessary wall plugs. Unpack the unit,
make the measurements on the wall and place the unit on the surface where it should be mounted.
It is recommended to connect the power and audio cables to the Sound Bar before mounting on the
wall.

Center Line
Included in the box is a template for easy mounting. Use a level to ensure the template is in level, and then tape the
template securely to the wall. Use an awl or other sharp object to punch 4 small holes through 4 of the marked
locations on the template.
Removethetemplatefromthewallanddrillpilotholes.Pre-drillingisoptional,howeveritwill result in a more
accurateinstallation.
Insert and secure the wall anchors.
If drilling into wood stud, do not use the wall anchors.
If drilling into Sheetrock, screw the wall anchors into the drywall with a Phillips head screwdriver until the head is flat
against the wall surface. Be careful not to overtighten.
Fasten the Sound Bar brackets to the wall, using the screws supplied in the wall mount kit. Use a level to verify
accuracy a final time, and then tighten the screws securely.
Then screw the four thumb screws included in the box into the Sound Bar.
See drawing for correct placement.
Hang the Neets Sound Bar securely on the two (2) brackets and adjust the
two thumb screws (marked on the drawing for correct spacing to the wall.
For mounting the Sound Bar to a cart, use the VESA 400 or 800 holes at the rear of the Sound Bar.

RS-232 connector
The bi-directional RS-232 connector is used to control the Sound Bar from
compatible RS-232 control systems.
To connect the Sound Bar to a control system, connect Sound Bar G to ground on
control system. Connect Rx from Sound Bar to transmit/Tx from control system, and
Tx from Sound Bar to receive/Rx from control system.
See the section “RS-232 protocol” on page 13 for details of the protocol and
remember to set the mode selection switch as described below in “RS-232” mode.
Switch for selecting RS-232 or Auto on/off mode
This switch is used to select between the two operation modes of the Sound Bar.
For difference in operation modes see chapter “How to use” on page 9.
Balanced audio connector
The connector marked “BALANCED” is line level audio input which can be used in both
balanced or unbalanced mode. Connect the audio source using the supplied terminal
block.
To connect the input to a balanced source connect ground to the shield of both cables.

How to use
The mode select switch
The mode selection switch is used to select between RS-232 control mode and the Auto on/off mode combined with
one of the three EQ presets (Video Conference, Music & Present).
Auto On/off mode
When the switch is set in one of the three Auto on/off modes the Sound Bar will activate the Wake-on-signal
function and work autonomously powering on and off as described in “Wake-on-signal” chapter on page 10.
Setting the switch in Auto on/off mode will ensure that Wake-on-signal is activated even if Wake- on-signal
previously have been disabled by a command in RS-232 mode.
In Auto on/off mode the RS-232 control port will still be active, but the Sound Bar will not react to incoming
commands or queries. Instead, the Sound Bar will reply to a RS-232 command or query telling the connected
control system that the Sound Bar is set to Auto on/off mode.
RS-232 mode
In RS-232 mode, the RS-232 port will be active. The RS-232 port is used to control the Sound Bar by
commands and status from Sound Bar can be requested by queries.
The Wake-on-signal function will by default be disabled in RS-232 mode. But by RS-232 command it is possible to
activate the function if both Wake-on-signal and RS-232 control is needed for the application.
To control the Sound Bar by RS-232 connect a control system to the RS-232 port with the following
settings:
• Baudrate: 19.200
• Databit: 8
• Stopbit:1
• Parity: None
Please be aware that RS-232 control is deactivated if the Sound Bar is set to Auto on/off mode. The commands
for RS-232 control can be found on page 12.
When changing the mode switch from “Auto on/off” to “RS232” the Sound Bar will automatically apply
the following settings:
• Power = ON
• Mute = OFF
• Volume = 70 (If max volume is set lower than 70, then that will not be exceeded)
• Input = 1 (RCA Unbalanced)
• Wake on signal = OFF
• EQ setting = Video Conference.

Wake-on-signal technology
The Sound Bar is equipped with Wake-on-signal technology. This means that the Sound Bar is able to
automatically power on and off, if there is a signal present on one of the four connected sources.
For the USB input the soundbar looks for an active 5V signal in order for it to be detected as an active source.
For the HDMI(ARC) input the connected TV automatically powers on and off the soundbar using CEC when the
TV turns on and off. On some TV brands, it should be configured to use ARC as audio output and/or use CEC
to control the connected audio device’s power state. Check your TV manual for recommended settings
regarding ARC and CEC.
To trigger the Sound Bar to wake using the UNBALANCED (RCA) and BALANCED input, it needs to detect a
signal on the inputs. The signal sense trigger level is not adjustable.
When the Sound Bar have powered on the activating input source will be kept as the active source for as long as there
is a signal. When the signal is removed, the Sound Bar will be kept on for an additional 3 minutes before automatically
powering off again. And the wake-on-signal function will start over again sensing for an active signal.
The volume level for Wake-on-signal will be last used volume. That means coming from the factory the Sound Bar will
wake up at level 70 out of 100. If another volume level is needed for the specific application the volume should be
adjusted by RS-232 command.
When the Sound Bar is powered off the Sound Bar will sense on the audio inputs for one second at a time in a
circular manner. This means, that the time from activating the source until the Sound Bar starts the power on
process can take up to 2 seconds. So, in order to power on the Sound Bar simply output a signal on one of the
connected sources.
Equalizer presets
Three equalizer presets will provide enhanced listening experience for different use scenarios.
• Equalizer 1: Music. This setting has been optimized for best overall experience when listening to
various types of music.
• Equalizer 2: Video Conference setting, default setting RS232. Will enhance the experience when using
unified communication equipment with the Sound Bar.
• Equalizer 3: Present setting. Optimized for Presentations with a combination of videos and speech.
The presets can be selected using RS-232 commands or using the mode switch at the back of the sound bar.

Troubleshooting
RS-232 protocol
Command structure
TheNeetsRS-232protocolisstructuredina specialway,whichisdescribedhere.Theprotocol consists of
commandsto controltheSound Barand queriesto request statusfrom the Sound Bar.
Both commands and queries is a two-way data exchange where the command or query is sent to the Sound Bar. The
Sound Bar responds with an acknowledge to a command and a value to a query.

12
Commands or queries send to the Sound Bar
Commands or queries to the Sound Bar is always structured the same way:
Replies from the Sound Bar
The Sound Bar will reply with an acknowledgement to a command to indicate that the command
have been accepted
Reply
on
accepted
command:
NEUNIT=1,OK\CR
If a query is sent to the Sound Bar the reply will be equal to the query with the question mark
replaced by the actual string or value matching the query:
Reply

a
query:
NEUNIT=1,POWER=ON\CR
If the Sound Bar detects an error in the command or query received, the Sound Bar will reply with
the following reply indicating an error.
Reply

errors:
NEUNIT=1,ERR\CR
If the Sound Bar is set to Auto On/off mode by switch on back panel and there is an incom- ing
command, the Sound Bar will reply with the following indicating an error.

mode:
NEUNIT=1,ERR_MODE_SWITCH_IN_AUTO\CR
All RS-232 communications is case sensitive.
It is possible to send multiple commands without time delay between commands by delimiting each
command with the command ending \CR.
When adjusting any settings using RS-232 commands the changes will automatically be saved in the Sound Bar.
The saved settings will be used as default values next time power is connected to the Sound Bar. This function could
be used to change the volume in “Auto On/off” mode.
