S Register 122 - Remote Control
This register either disables or enables remote control at a repeater or slave
unit. When disabled, a slave/repeater’s settings may be remotely read by the
master, but may not be remotely modified. When enabled, the
slave/repeater allows the network master full remote control access. See
Section 4.4.3 for details. The default is 0 - disabled.
S Register 123 - RSSI Reading
This register displays the average signal strength in dBm over the previous
four hop intervals. The value in this register is also reflected in status lines
RSSI1,2 and 3. See Section 2.2 for a description of RSSI, and how it is
derived.
