EL CTROCH M Che ATTN G TOMORROW APPLICATION NOTE AN203 Network Addressing Introduction Electrochem s sensors and base stations are both factory set to have the same default networking parameters stored in their memory If there are multiple sensors attempting to communicate for example on the same communication channel then there will be interference One way to work around this would be to change the Channel and or PAN ID parameters of the sensor as well as the base station This application note describes how to properly configure a sensor with a base station How to Configure Network Addressing Parameters Start by entering a Radio AT command as described in the Radio AT RAT application note and in the RAT section of the user manual to alter the desired networking parameter of the sensor This command may be entered into the X CTU terminal window Note that only a response data frame will be returned at this time to indicate that a command has been sent to the sensor Next in order to configure the base station select the Modem 27 X CTU COM3 Configuration tab also in the X CTU PC Settings Range Test Terminal Modem Configuration application and then click the Read Modern Parameters and Firmware q r Parameter Yiew r Profile Versions button Under the Networking amp Read write Restore _Ciear Screen Save Download ai Security section the Channel and Always update fiimware taoti eat e
