Monitoring the test transmission using the receiver
The user can monitor the quality of the received data by visually inspecting the received data
stream. The packet identifier number helps to keep track of possibly lost messages. Error-free
reception of data can be checked by using a suitable terminal program, which may calculate
BER (Bit Error Rate) or PER (Packet Error Rate) performance of the radio links.
The signal strength of the reception can be monitored also by:
• Enquiring the RSSI level from the radio modem by using the SL command (SL@R?). In that
case the SL commands must be enabled in the radio modem setup.
• Monitoring the LCD display (models equipped with the LCD)
