Each ZS Sensor on an Rnet must have a unique address, but addresses do not have to be sequential.
Use the DIP switches on the back of the ZS Sensor to set an address from 0 to 14. (0 is factory default.) Each DIP
switch has the value shown in the figure below. Turn on as many DIP switches as you need so that their total value
equals the address.

EXAMPLE DIP switches 1 and 4 above are on. Their values (1 + 8) total 9, so the sensor's address is 9.

To wire and mount a ZS Sensor
PREREQUISITE The Rnet cable is wired to the controller. The shield wire and the ground wire should be inserted
into the controller's GND terminal.
1 Turn off the controller's power.
2 Pull the backplate off the ZS Sensor. You may need to turn the setscrews in the bottom of the sensor
clockwise until you can remove the backplate.
3 Pull the Rnet communication cable through the slit in the insulated backing material.
3.30 in.
(8.38 cm)
4 Use 2 screws to mount the backplate to the wall or outlet box.
5 Partially cut, then bend and pull off the outer jacket of the Rnet cable(s). Do not nick the inner insulation.

.25 in.
(.6 cm)
Shield wire
6 Strip about .25 inch (.6 cm) of the inner insulation from each wire.
7 If wiring 1 cable to the ZS Sensor, cut the shield wire off at the outer jacket, then wrap the cable with tape at
the outer jacket to cover the end of the shield wire.
If wiring 2 cables in a daisy-chain configuration, twist together the shield wires, then wrap the shield wires
with tape.

8 Insert the other 4 wires into the ZS Sensor's screw terminal connector. If wiring 2 cables, insert like-colored
wires into each terminal.

CAUTION Allow no more than 0.06 inch (1.5 mm) bare communication wire to protrude. If bare
communication wire contacts the cable's foil shield, shield wire, or a metal surface other than the terminal
block, the device may not communicate correctly.
9 Attach the sensor's cover and circuit board to the mounted backplate, inserting the top first.
10 Turn the setscrews one full turn counterclockwise so that the cover cannot be removed.
11 Turn on the controller's power.
NOTE Use the same polarity throughout the Rnet.

You can connect to the Local Access port of the ZS Sensor to perform test and balance or to make changes to any
device on the network.
PREREQUISITES
• A computer with a USB port
• A USB Link Kit
CAUTION If multiple controllers share power but polarity was not maintained when they were wired, the
difference between the controller's ground and the computer's AC power ground could damage the USB Link Kit
and the controller. If you are not sure of the wiring polarity, use a USB isolator between the computer and the USB
Link Kit. Purchase a USB isolator online from a third-party manufacturer.
Connect the USB Link Kit to the computer and to the ZS Sensor's Local Access port.

To set up a Local Access connection in the WebCTRL® for OEMs
interface
For the WebCTRL® for OEMs application to communicate with the Local Access port, you must do the following:
1 On the System Configuration tree, select Connections.
2 On the Configure tab, click Add.
3 From the Type drop-down list, select BACnet Local Access.
4 Optional: Edit the Description.
5 Type the computer's Port number that the USB cable is connected to.
NOTE To find the port number, plug the USB cable into the computer's USB port, then select Start >
Control Panel > System > Device Manager > Ports (Com & LPT). The COM port number is beside
Silicon Labs CP210x USB to UART Bridge.

6 Set the Baud rate to 115200.
7 Click Accept.
8 On the View tab, click the button next to the BACnet/IP network, then select BACnet Local Access.
9 Click Accept.
10 On the Configure tab, select BACnet Local Access, then click Start.
NOTE If an error message appears, make sure the COM port you selected is not in use. For example, PuTTY
may be open and is holding the port open.
11 On the Network tree, select the controller that you are connected to.
12 Click , then select Manual Command.
13 Type rnet here in the dialog box, then click OK.
14 On the Properties page, click Module Status. If a Modstat report appears, the WebCTRL® for OEMs
application is communicating with the controller.

Then...
Incorrect or missing
values
Check for errors in WebCTRL® for OEMs.
On the control program's Properties page, select the Rnet Points tab.
Verify that values coming in from the sensors and those going out to the
sensors are expected values.
On the control program's Logic page, double-click the Sensor Binder and
ASVI microblocks to check for problems in the Status and/or Error
columns.
If the Error column shows Resource Allocation, try formatting the
sensor (page 13). If the error is not corrected by formatting, the control
program engineer should reduce the number of items that the sensor is
trying to display.
Nothing
The sensor has no power.
The sensor is not communicating with the network. Check:
• Software/addressing setup
• Wiring connections
• Controller operating status

Characters that
seem out
of place
The sensor may have a memory problem. Try formatting the sensor (page
13).
!
To format a ZS Sensor
Formatting a sensor clears its flash memory. Do either of the following to format a sensor:
• Download the controller that the sensor is connected to.
• Do the following:
a) Remove the wiring connector from the sensor.
b) Note the current position of the DIP switches.
c) Set all DIP switches to the ON position.
d) Reattach the wiring connector to format.
e) After approximately 3 seconds, remove the wiring connector.
f) Set the DIP switches back to their original position.
g) Reattach the wiring connector.
NOTE If you move a sensor from one controller to another controller that has a different control program, format
the sensor.
