Longo programmable controller LPC-2.SM7

2 DESCRIPTION

The LPC-2.SM7 is a multi sensor which consists of the following sensors: lux sensor for light intensity
measurements, IR matrix sensor for temperature measurements and IR receive/transmit for IR
communication.

Measuring light and temperature intensity provides the information needed for achieving good work
conditions. IR transmit feature can be used for remote controller substitution, for example air
conditioning can be controlled from Smarteh main module via LPC-2.SM7 in parallel with remote
controller. On the other hand, IR receive feature can be used for receiving commands to the main
module from Smarteh remote controller, smartphone or other remote controller. LPC-2.SM7 can
recognize RC-5 IR protocol which is used in Smarteh remote controller or 15 different learned IR
commands which can be learned in IR learning mode. Only learned commands can be transmitted.

LPC-2.SM7 is controlled and powered from the main module (e.g., LPC-2.MC8, LPC-2.MC9) via
Smarteh bus.

4 OPERATION

LPC-2.SM7 can be in one of two operational modes - normal or error. When LPC-2.SM7 is in normal
mode, module parameters can be read or written via Smarteh IDE software.

4.1 Operational modes

Normal

Communication with the main module is working. Only green “PWR” LED2 is turned on.

Error

In case of communication fault, red “ERR” LED1 will turn on.

4.2 Parameters

If parameter is set to logical “1”, is considered to be active, enabled or set. If parameter has logical
value “0” is considered to be inactive, disabled or cleared.

Parameter can be a command or feedback. When parameter is marked as feedback it means that
LPC-2.SM7 is sending information to the main module. On the other hand, command represents
request from the main module to the LPC-2.SM7.

Command:

IR command number selection for transmit [oIrCmdSendNum]: This parameter is used to
select the IR learned command which will be used for transmit.
Type: WORD
Raw to engineering data: 1 .. 15 IR transmit command 1 .. IR transmit command 15→

IR command transmit control bit [oIrCmdSend]: When this bit goes to "1", selected IR
command in oIrCmdSendNum is transmitted.
Type: BOOL
Raw to engineering data: “0” No transmit→

“1” Transmit selected IR command →

IR protocol selector [oIrProtocolSel]: Selector for IR receive protocol.
Type: WORD
Raw to engineering data: 0 Learned IR commands→

1 RC-5 IR protocol→

Feedback:

Actual light intensity value [iLight]: Actual measured light intensity value.
Type: WORD
Raw to engineering data: 0 .. 1490 0 .. 1490 lux→

Grid-eye minimum actual temperature value [iGEyeMin]: Actual minimal temperature
value measured by IR matrix sensor.
Type: WORD
Raw to engineering data: 0 .. 12000 0 .. 120.00 → °C

Grid-eye maximum actual temperature value [iGEyeMax]: Actual maximum temperature
value measured by IR matrix sensor.
Type: WORD
Raw to engineering data: 0 .. 12000 0 .. 120.00 → °C

4

Longo programmable controller LPC-2.SM7

Grid-eye average actual temperature value [iGEyeAvg]: Actual average temperature
measured by IR matrix sensor.
Type: WORD
Raw to engineering data: 0 .. 12000 0 .. 120.00 → °C

Toggle communication bit [iComm]: At each valid Rx packet from main module, this bit is
toggled.
Type: BOOL

IR command number received value [iIrCmdRecNum]: This parameter depends on the
oIrProtocolSel parameter. Latency between touched button on the remote controller and
reception on the main module is max. 1 s.
Type: WORD

If oIrProtocolSel
is "0":

When LPC-2.SM7 receives an IR command, value of iIrCmdRecNum corresponds to the
number of the IR learned command. Value is set back to 0 after next communication
cycle with main module or after approximately two seconds regardless
communication.

Raw to engineering data: 1 .. 15 IR receive learned command 1 .. IR receive →

learned command 15

is "1":

When LPC-2.SM7 receives an IR command, value of iIrCmdRecNum corresponds to the
number described below in binary code which includes toogle bit, address code and
data code of the RC-5 protocol. When button is released, value gets to 0 after next
communication cycle with main module or after approximately two seconds
regardless communication.

4.3 IR learn, receive and transmit

LPC-2.SM7 module can be learned to recognize 15 different IR commands. Module enters IR learning
mode as soon as the left pair of DIP switches (S1) are not in position for "No learning - receive only" –
see table 4.

IR learn is demonstrated on the example on how to learn LPC-2.SM7 the IR command "power ON"
from third-party IR remote controller for air conditioning and store it under command 15 in the LPC-

2.SM7 internal memory. IR receive and transmit is demonstrated on the example how to verify
stored IR commands.

IR learn

Set the S1 DIP switches to the setting than corresponds to the number under which IR command will
be stored. In this example, switches must be set to setting "learning mode for command 15". Once
this is done, LPC-2.SM7 is ready to receive the IR command from the remote controller and store it
to internal memory under command 15.

Press the button on the IR remote controller which you want it to be stored under command that is
set with DIP switches on LPC-2.SM7. In this example, press "power ON" button on the IR remote
controller. Once the button has been pressed, the LPC-2.SM7 stores the IR command to internal
memory, in this example under command 15. LPC-2.SM7 will not store any other command under
command 15, unless S1 DIP switches has been changed to other setting and back to the setting
"learning mode for command 15".

IR receive

Which protocol should be used for IR receive, user can select with IrProtocolSel parameter. To check
if the IR command has been learned and stored correctly IrProtocolSel parameter must be "0".

Set the DIP switches to the setting "No learning - receive only" and than press button "power ON" on
the IR remote controller. If the received IR command corresponds to any of the IR commands stored
in the LPC-2.SM7 internal memory, the command number under which the received IR command has
been stored will be shown in the feedback parameter iIrCmdRecNum. In this example, number 15
should be shown.

If IrProtocolSel is set to "0" and DIP switches to the setting "No learning - receive only" than LPC-

2.SM7 will receive learned IR commands only.
If IrProtocolSel is set to "1" and DIP switches to the setting "No learning - receive only" than LPC-

2.SM7 will receive RC-5 IR protocol only.

Be advised that during IR transmit, IR receive is blocked.

IR transmit

In order to check if the IR command that was stored can also be transmitted correctly, the LPC-

2.SM7 should be used as a substitution of the IR remote controller. On the main module, number 15
should be written to the LPC-2.SM7 command oIrCmdSendNum. This command selects IR command
which is stored under number 15 for transmit. IR transmit is executed once oIrCmdSend is set to
logical “1”. In this example, air conditioning should be turned ON.

Procedure for IR learn can be repeated for 15 different IR commands. DIP switch setting corresponds
to learning mode for one of 15 commands and IR receive only mode – see table 4.

The IR commands may also be learned during manufacturing process - consult with Smarteh.

5.2 Mounting instructions

Figure 3: Housing dimensions

Dimensions in milimeters.

All connections, module attachments and assembling must be done
while module is not connected to the main power supply.

Mounting instructions:

1. Set the correct RS-485 address for LPC-2.SM7 (refer to the table 5).

2. Install the LPC-2.SM7 module on the position which provides maximum effect for its features
with the magnets or screws2. Magnets can be pushed to the other side of abutment surface if
needed.

3. Connect interconnection cable to the main module.

LPC-2.SM7 module must be installed properly, isolating any potential connection with electrical
sources other than power supply from main module. Improperly installed module may cause failure
of the module itself, other devices on the same wiring, main module or may lead to fire or personal
injury.

LPC-2.SM7 is connected to the main module with interconnection cable (e.g. SSK, ICM-7). When
more modules are connected to the main module, splitter (e.g. SPL-2) is also required (figure 2).

NOTE: Signal wires must be installed separately from power and high voltage wires in accordance
with general industry electrical installation standard.

2 Screws are not supplied with sensor.
