2. Verify the Gateway is installed and configured before continuing with the
Endpoint configuration.
3. Connect the WC-USB-4PIN - 4-pin to USB programming cable to the
computer and the WC20i.
4. Open the WC Toolkit software.
The Select Device window opens.
5. Click the Refresh button to have WC Toolkit search for and list the available
COM ports reported by Windows and connected devices in the COM Port
list box.
6. Click the COM Port list box arrow and select the COM port on the computer
associated with the connected WC20i-485 or WC20i-485-S.
7. Click the Auto-Detect Device on COM Port button to have WC Toolkit
connect the device to the COM Port selected in the COM Port list box.
The Device Configuration window opens for the selected device.

8. In the Set Encryption Key area (#5), change these settings:
a. In the Key text box, enter the encryption key for the device using 6 to 16
characters.
b. Click the Set button to save the information.
Important!: A Key CANNOT contain spaces or angle brackets.
The Gateway and Endpoints only communicate if they are configured
with the same Key. When setting up a new network, use this same
encryption Key on all the devices.
Note: When the WC20i drops its network, it attempts to join networks
using the same encryption Key.
Caution: It is possible to hide the encryption Key so it cannot be
read. This is the most secure option, but if the Key is forgotten,
there is no way to recover it.
The Key must be reset on every device on the network.
9. Optional: Click the Settings menu and select Set Encryption Key
Unrecoverable to permanently hide the key.
10. In the Settings area (#6), change these settings:
Note: The Network settings are used to create separate networks using
multiple Gateways (that are in close proximity to one another).
Important!: The Radio Network and Radio Network Group settings
are selected by the user but MUST MATCH the existing Gateway
network for successful communication between the Gateway and
Endpoint.
a. Optional: In the Node Name text box, enter a name for the Endpoint
using a maximum of 10 characters.
b. Click the Set button to save the information.
c. Click the Radio Mode list box arrow and select either Sleeping or Non-
Sleeping.
Important!: Use Non-Sleeping option ONLY if there is a solar kit
attached to the WC20i. See Included Equipment (on page 1) for
additional information.
d. Click the Radio Network list box arrow and select 0 (zero) to 7 for the
assigned number.
e. Click the Radio Network Group list box arrow and select 0 (zero) to 29
for the network group assigned number.
Important!: The Radio Network and Radio Network Group
settings are selected by the user but MUST MATCH the existing
Gateway network for successful communication between the
Gateway and Endpoint.
f. Click the Set button to save the information.
g. Click the Checkin Interval list box arrow and select how often the
Endpoint wakes up, reads the sensor values Modbus device, and
transmits the register data to the Gateway.
h. Click the Set button to save the information.
i. In the Sensor On time (sec) text box, enter the number of seconds
power is applied to the Modbus sensor prior to data collection.
FREEWAVE Recommends: Accept the default Sensor On time
(sec) value of 2 seconds for most devices.
However, radar sensors often require a longer warm-up time.
Note: See the sensor manufacturer’s documentation for more
information on warm-up time for the specific sensor.
j. Optional: Select the Sensor Always On check box to make the sensor
always have power no matter what type of power source is connected to
the device.
Caution: Having the Sensor Always On selected is useful
for rapid data collection on a sensor that has a long warm-up
time. However, it will shorten the battery life dramatically
unless a Solar Powered WC20i is used.
k. Click the Set button to save the information.
l. Optional: Click the Sensor Power Mode list box arrow and select either
HIGH or LOW volts for the WC20i.
Note: HIGH outputs 18.5 volts to the sensor and LOW outputs 12.5
volts. LOW results in longer battery life but some sensors require a
higher voltage.
m. Click the Set button to save the information.
11. On the WC20i, press the Check-in button to apply power to the configured
sensor, read the sensor values, and send the collected sensor data to the
Gateway.
12. Verify the Gateway is communicating with the Endpoints.
Note: A successful connection on the WAVECONTACT Endpoint is
indicated with Green blinking TX and ACT lights and a Red blinking
light for RX. If the connection is NOT successful, a Green blinking
TX light appears for 10 seconds.
FREEWAVE Recommends: Install and configure the WC45i Gateway
before any Endpoints to ensure the Endpoints have connectivity after
installation.
13. Continue with Modbus Program Steps Configuration (on page 6).
14. Close the WC Toolkit software.
15. Remove the WC-USB-4PIN 4-pin to USB programming cable from the
computer and the WC20i.
16. As applicable, replace the Endpoint cover.
17. Install the WC20i using the Direct Mount to Sensor with Short Conduit
procedure in the WC20i-485 or WC20i-485-S Modular Endpoint User
Manual (FreeWave Part #: LUM0093AA).
