Important Safety Instructions
Caution:
Read these instructions.
Read and understand all safety and operating instructions before using the equipment.
Keep these Instructions.
The safety instructions should be kept for future reference.
Heed all warnings.
Follow all warnings and instructions marked on the equipment or in the user information.
Avoid attachments.
Do not use tools or attachments that are not recommended, as they may be hazardous.
Warning!:
• This equipment should be operated only from the included power supply.
• To remove power from the equipment safely, remove all power cords from the rear of the equipment, or the
desktop power module (if detachable), or from the power source receptacle (wall plug).
• Power cords should be routed so that they are not likely to be stepped on or pinched by items placed upon or
against them.
• Do not defeat the safety purpose of a polarized or grounding-type plug. A polarized plug has two blades with one
wider than the other. A grounding-type plug has two blades and a third grounding prong. The wide blade or the
third prong is provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for
replacement of the obsolete outlet.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Refer all servicing to qualified service personnel. There are no user-serviceable parts inside. To prevent the risk of
shock, do not attempt to service this equipment yourself because opening or removing covers may expose you to
dangerous voltage or other hazards. Contact your local Neets reseller or distributor.
• If the equipment has slots or holes in the enclosure, these are provided to prevent overheating of sensitive
components inside. These openings must never be blocked by other objects.
• Do not use this equipment near water.
• To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture and objects filled
with liquids.
• Unplug the product before cleaning. Clean only with a dry cloth and not cleaning fluid or aerosols. Such products
could enter the unit and cause damage, fire, or electric shock. Some substances may also mar the finish of the
product.
FCC Class A Notice:
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part
15 of the FCC Rules. Operation is subject to the following two conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including interference that may cause undesired operation.
The Class A limits are designed to provide reasonable protection against harmful interference when the
equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful
interference, in which case the user will be required to correct the interference at his own expense.
FCC regulations state that any unauthorized changes or modifications to this equipment, not expressly approved by
the manufacturer, could void the user’s authority to operate this equipment.
The lightning bolt triangle is used to alert the user to the presence of uninsulated “dangerous
voltages” within the unit’s chassis that may be of sufficient magnitude to constitute a risk of electric
shock to humans.
The exclamation point triangle is used to alert the user to presence of important operating and
service instructions in the literature accompanying the product.

Installation
The Neets Control – LiMa is designed to be easily installed in any convenient location. The unit can be
placed on a desk free standing. Simply unpack the unit, mount the adhesive feet and it is ready to go.
Alternatively, the unit can be mounted under a table or on a ceiling with the included self-tapping
screws. Unpack the unit, place the unit on the surface where it is to be mounted, and screw the
two screws through the holes in the top as shown below:

The USB port is used exclusively for configuring the LiMa from the Neets
Project Designer software. It can’t be used to control any external devices.
on
The LiMa must be powered by PoE supply that complies with IEEE
802.3af and 802.3at, type 1 in order to configure it by USB.
The USB connector for connecting to the LiMa is “mini USB B 5P”. You
can buy this cable on the web (select a USB A to Mini USB B 5P).
RS-232 Status Indication
The RS-232 status LED displays the current status of the RS-232 ports.
The LEDs illuminate when there is active communication on the port.
IO Status Indication
The IO status LED displays current status of the I/Os.
When an IO is configured as input, the yellow LED marked “in” will
illuminate when the input is high and turn off when the input is low.
The green LED marked “out” will remain off.
When an IO is configured as output, the green LED marked “out” will
illuminate when the output is high and turn off when the output is low.
The yellow LED marked “in” will remain off.

The two test buttons are used to test the built-in relay function. The test
buttons are intended for use during installation to control functionality of connected devices. The LEDs will indicate if the relay is activated (green) or not
activated (off) during use of the test buttons. They will also illuminate when
the relays are controlled by the project in the LiMa.
Be aware that you can activate multiple relays at the same time and
damage connected equipment if not carefull.
uSD-Card
The uSD-Card stores the LiMa project setup created in the Project
Designer software, including general settings and Graphical User
Interface. The card should not be removed during normal operation.
To remove the SD Card from the unit, push it GENTLY into the holder about
1mm (by using your finger tip). Release again, and it will slide out.
REMEMBER to remove power from unit (power down) before removing uSD card!

The LiMa has two I/O (Inputs/Outputs) which can be configured as either
output or input. Each I/O is available for connection to a PIR (movement)
sensor, keyboard lock, relays or for other compatible uses. The ports are
not potential free; you may need external relays to prevent ground loops
depending on your application.
When used as outputs, the I/O ports are active low. When activated, the
I/O ports are tied to GND through a FET transistor (also called open drain/
collector function). Each I/O can draw up to 24VDC/500mA.
When used as inputs, the applied voltage must be below 1 VDC to be
accepted as LOW, and above 4 VDC (but below 24 VDC) to be accepted
as HIGH. The inputs are default HIGH and must be connected to ground in
order to change state.

LAN Connector with PoE functionality
The LAN connector is used to connect the LiMa to the local area network.
The LiMa has Power over Ethernet functionality built into the LAN interface
connector.
You must connect the LiMa to your LAN if you are using any of the LAN
features of the product. The port features auto MDI-X which means that
you can connect the LAN port directly to other devices without the need
for a LAN switch.
The connector marked with PoE IN is used to power up the
entire control system. To power the LiMa, use a PoE enabled
!
There are two LEDs on the connector with the following indication:
Color Off On Blink
Yellow No Link Link Activity
Green 10 Mbit 100 Mbit

Troubleshooting
Error indication using LEDs
If there is a fault in either the configuration or the Neets Control - LiMa unit, this will be
indicated on the front LED indicators.
In all error modes the power LED will flash red alternating with the IO LEDs. The alternating IO
LEDs will indicate type of error. See list below.
