1. OS-NET Introduction
Thank you for your interest in OS-NET,a simpler and smarter wireless lighting control solution developed by IR-TEC to
enable sophisticated controls onevery luminaire and lighting circuit. The OS-NET is also a wireless sensor mesh network
simultaneously deployedthrough installingthe OS-NET enabled luminaires andlighting circuits. TheOS-NETenabled
luminaire refersto the luminaire integratedwith anOS-NETSensor, and the OS-NETenabled lighting circuit refers tothe
power lineelectrically controlledby an OS-NETSensor.
The OS-NET network is formed by a number of wirelessly connected OS-NET devices; mainly refer to the OS-NET Sensors
(ONS) and the OS-NET Buttons (ONB). Each device not only provides its distinctive functionalities, but also operates as a
node to transmit, receive, orforward wireless communication commands within network.
After installing an OS-NET enabled lighting system, every OS-NET device should be grouped and linked with the network
to enable smart lighting control as desired via operating a SRP-281, a 2-way IR remote programmer exclusively designed
forconfiguring OS-NET devices. This guideis prepared to help conductallnecessaryconfigurations and settings correctly.

3.2 GROUP LINK setting
GROUP LINK is a fundamental setting forall OS-NET devices of an OS-NET enabled lighting system. Every OS-NET device
must beassigned to agroupto linkup thenetwork. To conduct GROUPLINK setting,press from MAIN MENU
and select the GROUP LINK to enter the setting pages. Threeoptions are available for selection.
lEZ-GROUP
EZ-GROUPsetting allowsyou toquickly groupand link the OS-NET devicesto the network. Most group controls can be
achievedby EZ-GROUP setting. Followthe proceduresbelowto conductEZ-GROUP setting;
1. Afterentering the EZ-GROUPpage, youcansee 4 lines of MBR OF GRP(Memberof Group) forgroup number
assignment.Each line representsa member of groupto beassigned for the device.
2. Press or to select the group number(001-250) to be assigned forthe target device. If the target
sensorisa memberof multiplegroups, you should alsoselect thegroupnumberforthe2nd,3rd or 4th line.
3. Aim at the target sensor and press to upload the grouping data while also linking up the network.
NOTE: The grouping sensor will blink its LED inBLUE and GREEN intermittently while linking up the network and
eventually display in GREEN to indicate successfulnetwork linkage.
Changing Group
To change the group assignment of a specificdevice, enter the EZ-GROUPpage and select the NEWgroupnumber(s) to
be assigned, aim at the target device and press to upload the grouping data. The sensorwill switch on and off
the connected light two timesto acknowledge the group change.
lADVANCED
Although most group controlscan be achieved by EZ-GROUPsetting, some specificspaces may require sophisticated
group control.This would require the ADVANCEDsetting.
Exampleof specialgroupcontrol:When Zone A isoccupied, the lightingof ZoneA and B shouldbe activated. Butwhen
Zone B isoccupied, onlythe lightingof ZoneBare required to be activated.
The group control of OS-NET Sensors isactually a combined operation of TRANSMITTING and RECEIVING groups. To
achieve the above control, you canuseEZ-GROUPto setup the OS-NET Sensors of ZoneA and ZoneB with respective
group numbers. Then usethe ADVANCED setting tochange the number of TRANSMITTINGor RECEIVINGgroup of zone
sensors. You can eitheradd thegroup number of Zone B to the TRANSMITTINGgroup of Zone A sensors, oradd group
number of ZoneA tothe RECEIVINGgroup ofZoneB sensors.
lUNGROUP
The UNGROUP settingcan be usedto off-link aspecificOS-NET device fromthe connected network. Ungrouping an
OS-NETdevice may be needed if the device hasbeen mistakenlyconnectedto the neighboring network. Toungroupan
OS-NETdevice, select the UNGROUPunder the GROUPLINKpage, and press to enter the UNGROUPING page.
Press or to select YES and press to confirm UNGROUPING. Aimtoward the target device and press
againto ungroup.
NOTE: An ungrouped OS-NET Sensor can still control the connected lightsin standalone basis as set,but an ungrouped
OS-NET Button is functionless.

OS-NET Programming Guide
OS-NETPG-EN-IRT-18R0.docx 9
3.3 Creating a new OS-NET network
After installing the OS-NET enabled lighting system, anew OS-NET network should be created to link all devices to
enablethe group control. Follow the instructionsbelowto create anew OS-NET network.
1. Ensure the field is free of open (unlocked) OS-NET network. See the NOTE below.
2. Assign the 1st OS-NET Sensor to its group (ex. 001). The LED indicator will blink from BLUE to GREEN andcontinue
for aperiod of time.Please note that 001 isjust anexample,you can use any appropriate group number.
3. Assign the 2nd OS-NET Sensor to the same group (ex. 001) within 1 minute. The LED’s of two sensors shall blink
in BLUE and GREEN intermittently. If both sensors eventually display in GREEN,it means thatan OS-NETnetwork
is created successfully.
NOTE: To verify if the field is clear of other OS-NET network, you can select a newly installed OS-NET Sensor and test
with a temporary EZ-GROUP setting. Wait and observe the sensor LED after uploading the group setting data. If the
sensor LED eventually turns to BLUE after the network linking process completed, it means that the field is clear.If the
LED eventually displays in GREEN, itmeansthat thefieldhas an open OS-NET. Execute the UNGROUP process to off-link
the testing sensor fromthe connected network toprevent cross-network groupcontrol which isnormally undesired.
3.4 Adding more OS-NET devices to an existing network
To linkmore OS-NETdevicestoan existingnetwork, youcancontinuetogroup the otherOS-NETdevices viaEZ-GROUP
setting.After thegroupingcommandis dulyreceived, the device will blink its LED while scanningfor anopen OS-NET
and linkup automatically. Continue grouping all other devices and then conduct the DEVICEcontrol settings as required.
3.5 DEVICE setting
DEVICE setting is to configure how an OS-NET Sensor will control the connected lights. The network connected OS-NET
Sensorscan be configured in individualorgroup basis.
Setting an individual sensor
Select the INDIV-SET after enteringtheDEVICE setting page.Selectthe desired control scheme and parameters page by
page and upload the settings to the target sensor. A single lamp sign (5) will display at the upper right corner of all
pages to indicate the settings are forindividual sensor.
Setting allsensors in group basis
Select the GROUP-SET afterentering theDEVICE settingpage. Select the desired control schemeandparameters page
by page and upload the settings to an OS-NET Sensor, all other sensors of thegroup will control the connected lights in
the same scheme and parameters. A double lamp sign (55) will display at the upper right cornerof all pages to
indicate the settings are for grouped sensors.
The following items are availablefor setting the OS-NET Sensors.
lCONTROL
Every OS-NET Sensor can be set to provide different sensing control schemes to the connected light,including typical
on/off switching,bi-levelor continuousdimmingbased on occupancy, vacancy anddaylightsensing control strategies.
Following table highlights all control schemes available forthe OS-NETSensor.
