Configuration
Note: The terms node and Endpoint are used interchangeably in this
document.
FREEWAVE Recommends: Install and configure the WC45i Gateway
before any Endpoints to ensure the Endpoints have connectivity after
installation.
Important!: The RS232 Config / Debug connector on the WC45i-GW
MUST be used for WC Toolkit access.
The Config / Debug port is accessed by a direct connection to the WC45i-GW-
485 RS232 Config / Debug connector port.
Note: The screenshots are examples only.
The dialog boxes and windows appear differently on each computer.
1. Verify the WC Toolkit software is installed on the computer connected to the
WC45i-GW-485.
2. Open the WC Toolkit software.
The Select Device window opens. (Figure 15)
Figure 15: Select Device window

6. In the Settings area (#5), 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. Click the Radio Network list box arrow and select 0 (zero) to 7 for the
assigned number.
b. Click the Radio Network Group list box arrow and select 0 (zero) to 29
for the network group assigned number.
c. Click the Set button to save the information.
7. In the Set Encryption Key area (#6), 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 WC45i-GW-485 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.
8. Optional: Click the Settings menu and select Set Encryption Key
Unrecoverable to permanently hide the key.
Figure 17: Settings menu > Set Encryption Key Unrecoverable
9. Click Refresh List button to update the Modbus Slaves Reporting table
with all connected remote Endpoints.

10. Configure the Endpoints attached to the WC45i-GW-485.
Note: Use the Configuration procedure in the User Manual for these
WAVECONTACT Endpoints:
WC15i Multi-Input C1D1 Endpoint, WC20i Endpoint,
WC30i Wireless Pressure Sensor, WC40i Modbus Endpoint,
WC40i-COUNT Counter Endpoint, or WC40i-MB-RSD Modbus
Endpoint.
11. Optional: On the WC20i or WC45i-GW-485Endpoint, 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.
13. Close the WC Toolkit software.
14. Remove the WC-USB-DB9 USB to Serial DB9 programming cable from the
computer and the WC45i-BB.
