5. COMMUNICATION MODES
This chapter covers:
• The methods for using Waveport CF's four communication modes
• Command format
• Corresponding parameters
5.1 Frame exchange mode
This type of radio exchange allows you to send a request and then wait for a response from remote modules.
Following transmission of a radio frame, the Waveport CF radio stays in
reception mode for a period specified by the parameter
RADIO_USER_TIMEOUT. This allows the unit to receive a response from
the remote module.
The RS232 serial connection is not managed during this phase. This
command is generally intended for reading Wavenis-based telemetry
modules (temperature measurement, humidity, liquid flow, tank levels, digital
state management).
5.1.1 Configuring parameters
Frame exchange parameters are accessible REQ_READ_RADIO_PARAM and
REQ_WRITE_RADIO_PARAM. Parameter details are provided in Appendix III of this guide.
