Installation
Neets Sound Bar - SB1 is designed to be easily installed, in any convenient location. It can be
hung 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.
Add the Velcro band to the rear of the PSU as well as in the connection tray, at the
rear of the Sound Bar, and place the PSU in the connection tray. As well as connecting
the power, it is also recommended to connect the audio cables, before mounting on
the wall.
Incluced in the box is a template for easy mounting. Use a level to ensure the template is
horizontally, 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.
Remove the template from the wall and drill pilot holes. Pre-drilling is optional, however it will
result in a more accurate installation.
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.
Hang the Neets Sound Bar securely on the two (2) brackets.

How to use
The mode select switch
The mode selection switch is used to select between RS-232 control mode and Auto On/Off mode.
Auto On/Off mode
When the switch is set in the Auto On/Off mode 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 12.
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 13.

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 three connected
sources.
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. means, that the time from activating the source until the Sound
Bar powers on can take up to 3 seconds. To power on the Sound Bar simply output a signal on one
of the connected sources.
When the Sound Bar have powered on the activating input source will be kept as the active source
for as long as there is signal. When the signal is removed the Sound Bar will be kept on for
additional 3 minutes before automatically powering off again. And the wake-on-signall function will
start over again sensing for an active signal.
The volume level for Wake-on-signal will be last stored volume. That means coming from the facto-
ry the Sound Bar will wake up at 0 dB. If another volume level is needed for the specific application
the volume should be adjusted by RS-232 command.
To trigger the Sound Bar to wake the BALANCED and UNBALANCED input need to meet the
specified level mention in the specification section on page 8. Using the correct audio levels will
ensure the best possible user experience of the Sound Bar.
For the optical input an active audio signal shall be present in order for it to be detected as a
active source.
Equalizer presets
Three equalizer presets will provide enhanced listening experience for different use scenarios.
The presets can be selected using RS-232 commands.

Sound Bar do not react to the RS-232 commands
Make sure that the “RS-232” mode is selected. See section “The mode select switch” on page 12.
Sound Bar not waking from signal in auto mode
Make sure slide switch on back is in “Auto on/off” position. See section “The mode select
switch” on page 12.
Turn up volume on the device signal device.
The sound is too low when using the Sound Bar in “Auto On/Off”
As default, the output level is set to 0dB.
First: Adjust the volume, at connected device, for increasing the output level.
Second: Changing the default volume level: go to RS-232 mode, and adjust level.
The level set in RS-232 mode, is saved and used in “Auto On/Off” mode.
The sound is too high when using the Sound Bar in “Auto On/Off”
As default, the output level is set to 0dB.
First: Adjust the volume, at connected device, for decreasing the output level.
Second: Changing the default volume level: go to RS-232 mode, and adjust level.
The level set in RS-232 mode, is saved and used in “Auto On/Off” mode.
RS-232 protocol
Command structure
The Neets RS-232 protocol is structured in a special way, which is described here. The protocol
consist of commands to control the Sound Bar and queries to request status from 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.

Page 14 of 16
Commands or queries send to the Sound Bar
Commands or queries to the Sound Bar is always structured the same way:
A header: “NEUNIT=1” all commands, queries and replies start with the header
The header and following command is delimited by a comma mark “,”
Followed by the command: “POWER=ON”
A command can be changed to a query by replacing the string or number after the equal sign
with a question mark “?”
And ending with a carriage return: “\CR”
Carriage return is commonly referred to as “CR”. If you need to enter it in hexdecimal,
the value is 0D and in decimal, it is 13
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 to 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 on 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.
Reply when set in Auto On/Off 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.
