13. Once you have sent the configuration to each wireless module, the wireless network configuration is
complete. The 4 vertical RF Link LEDs on the wireless modules should illuminate. On the master wireless
module (Yellow Thumbwheel on 01) should have one amber LED illuminated (assuming there is more than
one slave wireless module in the network) and depending on the antennae on the slave wireless modules,
there should be an amber and module green LEDs illuminated.
The wireless network configuration is complete and is set up for transparent serial communication.
Configuring the two GW MODBUS TCP/RTU 1E/DB9 module for Modbus RTU to TCP
communication
1. The GW MODBUS TCP/RTU 1E/DB9 comes with a default IP address of 192.168.254.254. Set your
computer’s IP address in the same network as the GW MODBUS TCP/RTU 1E/DB9 (192.168.254.XXX).
Reference the data sheet for power connections and apply power to all three gateways.
2. For the GW MODBUS TCP/RTU 1E/DB9 that will be connected to the master RAD-900-IFS wireless module
(yellow thumbwheel 01), there is no configuration needed. The default settings of the GW MODBUS
TCP/RTU 1E/DB9 are compatible with the settings made on the master RAD-900-IFS.
3. Connect a standard straight through RJ45 Ethernet cable from your computer to the LAN port of the GW
MODBUS TCP/RTU 1E/DB9 that will be connected to the RAD-900-IFS module with yellow thumbwheel
address 02. Open an Internet browser and navigate to the webpage by typing in 192.168.254.254 in the
address bar. Login with User Name ‘Admin’ and password ‘admin’.
4. Next, navigate to the ‘LAN Setting’ tab and change the IP Address to 192.168.254.2. Click ‘Apply Changes’.
You will need to re-login at the new IP address once the change is made.
