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

Caution

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.

Cable details

RJ-12

NetSensor Installation and Operation

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.

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.

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.

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

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.

NetSensor Installation and Operation

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.

NetSensor Installation and Operation

Temperature Button 1—the space temperature sensor inside of the

NetSensor—is assigned to an analog variable in KMD controllers or

an analog value object in BACnet controllers.

◆Operators can view the room temperature by pressing Button 1

but cannot change the value.

◆The setting in Range (WinControl) or Display Format (BACstage)

sets the NetSensror display to either Fahrenheit or Celsius.

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
