Models KMD-1261 and KMD-1281 detect motion and change the
value of the auxiliary function.
• A value of -1 indicates motion
• A value of -2 indicates no motion
• A value of 0 or 1 indicates the auxiliary function is active.
The value of the auxiliary function will remain at 0 for approximately
30 seconds after power is applied to the NetSensor.

RJ-12
Network cable preparation
Connecting a NetSensor to a controller requires a six-wire cable with
RJ-12 connectors on each end. KMC plenum-rated preassembled
cables are recommended. Cables made to length must meet the
following requirements:
◆ Cable length must be no longer than 75 feet (22.9 meters).
◆ Cable conductors must be no smaller than #24 AWG.
◆ Cable insulation must meet local building codes.
◆ Connectors must be appropriate for the cable in use and are
installed following the connector manufacturers instructions.
Rough-in preparation
To prevent mounting screw heads from touching the circuit
board in the NetSensor, use only the mounting screws
supplied by KMC Controls. Using screws other than the
type supplied will damage the NetSensor.

Complete rough-in wiring at each sensor location prior to sensor
installation. This includes the following.
◆ Routing the network cable from the NetSensor to a controller.
◆ If required, installing the appropriate backplate. See Accessories
on page 2 for model numbers.
NetSensor mounting details
Installing the NetSensor
1. Turn the Allen screws in the base of the NetSensor clockwise
until they clear the cover. Swing the sensor away from the
mounting base to remove it.
Mounting screws
2. Route the RJ-12 cable through the mounting base.
3. Fasten the mounting base directly to a 2 x 4 inch outlet box or a
backplate with the Allen screws toward the floor.
4. Insert the RJ-12 cable coming from the base into the NetSensor.
5. Place the top of the NetSensor over the top of the mounting base
and swing it down over the Allen screw brackets. Be careful not
to pinch any wiring.
6. Back the Allen screws out of the brackets until they engage the
NetSensor cover and hold it in place.

PC data port
The NetSensor is equipped with a PC data port located at the bottom
of the NetSensor housing. This port provides a temporary connection
for setup or troubleshooting to either KMD Tier 2 or BACnet MS/TP
networks.
NetSensor PC port location and USB connection
To use the port to connect to a computer, use one of the following
connection methods. The exact connection depends on the computer
and the operator workstation software (see also the instructions
included with those devices and software):
◆ For a USB connection with either WinControl or BACstage, use a
KMD-5576 USB Communicator (see the illustration above).
◆ For a serial port connection to BACstage, use a third-party
interface.
◆ For serial port connection to WinControl, use a KMD-5559
CommTalk and KMD-5624 cable.
To use the PC data port:
1. Connect the keyed, flat end of the KMD-5624 NetSensor
interface cable to the port on the NetSensor. The KMD-5624
cable is included with the KMD-5576 but not the KMD-5559.
2. Connect the RJ-12 end of the cable to the interface device that
converts the EIA-485 signal from the NetSensor into a USB or
EIA-232 signal.
3. Connect the suitable cable from the interface device to the
computer ’s serial or USB port. Install any required software and
configure the port as necessary.

NetSensor Installation and Operation
Setpoint
Operation
The following sections describe the controls and indicators found on
the NetSensor.
Display The temperature display contains four 0.375-inch, 7-segment
LCD digits that are visible across a normal size office. The display
provides time, temperature and on the KMD-1281 humidity
readouts. Room temperature is displayed until either setpoint button
is pressed and then the display changes to setpoint mode.
Controls Models KMD-1261 and KMD-1281 include eight push
buttons; six of which (button 1 and buttons 3-7) are user
programmable. The actual operation of the programmable buttons
depend upon the program in the controller to which the NetSensor is
connected. See Programming
on page 11.
The arrow buttons adjust the programmed values up or down. Values
can be changed for all programmed buttons except the setpoint as
follows:
1. Press the button for the desired function.
2. Adjust the value up or down.
Setpoint Pressing either the up or down arrow buttons changes
the display from room temperature mode to setpoint mode. Each
additional time a setpoint button is pressed and released changes the
setpoint up or down.
Auxiliary function These NetSensors do not have auxiliary wires
found on earlier models. Press buttons 5 and 7 together and then
press an up arrow or down arrow button to change the auxiliary
function.

Maintenance
Remove dust as necessary from holes in top and bottom. Clean the
display and motion sensor cover with a soft, damp cloth and mild
soap.

Programming
Program a KMD-1261 or KMD-1281 by associating each button with a
variable or value object in the controller to which the NetSensor is
connected.
◆ See the illustration NetSensor button numbers on page 11 for the
button numbers.
◆ Table 1 lists the settings for programming a NetSensor with
WinControl. Use the NetSensor dialog found under the Control
Menu to configure each button.
◆ Table 2 lists settings for programming a NetSensor with
BACstage. Use the NetSensor dialog in the Device Menu to
configure each button.
Additional instructions on programming a NetSensor are included in
the program help for WinControlXL, BACstage, and TotalControl.

Setpoint The button 2 function up and down arrow buttons is
assigned to an analog variable in KMD controllers or an analog value
object in BACnet controllers.
◆ The precision of the display is set by Range in WinControl and
Display Format in BACstage. The typical value is 0.
◆ Operators can view and change the setpoint by pressing the
up or down arrow buttons.
◆ Write a Control Basic to control equipment based on the
conditions of the setpoint.
10 IF VAR2 < VAR1 THEN START OUT6
Displaying time Typically button 5 is configured to display time. It is
assigned to an analog variable in KMD controllers or an analog value
object in BACnet controllers. Add a Control Basic line as follows:
10 VAR5 = TIME
Verifying a functioning NetSensor Use NETSENSOR-STATUS in a
Control Basic program to check if a functioning NetSensor is
connected to the controller.
10 IF NOT NETSENSOR-STATUS THEN STOP OUT1
Verifying firmware version Simultaneously push Button 1 and Button
4 to display the version of the firmware in the NetSensor.
Motion sensing Program the Auxiliary function to detect motion in
the room.
• A value of -1 indicates motion
• A value of -2 indicates no motion
• A value of 0 or 1 indicates the auxiliary function is active.
The following Control Basic program detects motion and changes the
state of variable VAR9.
10 IF+ VAR8 = -1 THEN START VAR9 , STOP A
20 IF VAR8 = -2 THEN START A
30 IF TIME-ON( A ) > 0:02:00 THEN STOP VAR9
