MHX-2400 Operating Manual: Chapter 2 Initial Setup and Configuration 7
Signal strength, which is also reported in Register S123, is calculated based
on the last four valid received packets with correct CRC, and represented by
RSSI1, 2 and 3.
For slaves, packets are received on every single hop either from a repeater, or
the master.
When calculating RSSI, the master takes into consideration all packets
received from slaves and repeaters. Repeaters and slaves only transmit back
to the master when they have information to send. Therefore, if no data is
coming back to the master then RSSI will never get updated at the master,
and the LED’s will be off.
