Wavecard-Waveport User Manual Coronis Systems
5.4.2 Using broadcast mode (without waiting for response)
This mode allows you to address a request to all Wavenis modules within radio range of the transmitter
without waiting for responses. Depending to the EXCHANGE_STATUS settings, the local Wavecard is ready
for further RS232 serial link exchanges:
• After transmitting the broadcast request
• On reception of the END_MESSAGE_EXCHANGE command
