Relay Function Precautions
The received signal strength of the I/O Slave Stations can be confirmed on
the Serial Master Station. When a Relay Station is used, however, only the
signal strength between the Serial Master and Relay Station can be moni-
tored. To monitor the received signal strength at I/O Slave Stations connected
to the Relay Station, check the RSSI display on the I/O Slave Stations.
