3.0 Hardware Features
Receive Signal Strength Indicator (RSSI) (3x Green) LEDs
As the received signal strength increases, so does the number of
illuminated RSSI LEDs, starting with the furthest left. RSSI is
calculated based on the last four valid recieved packets. For robust
wireless communications performance, strive for a minimum of 2
RSSI LEDs being lit.
Initially, a remote unit’s RSSI LED’s will ‘scan’ (cycle from right to
left, each LED being on for 300ms in turn). Once the unit acquires
synchronization with the network, a ‘steady’ RSSI reading will be
displayed.
A Master updates its RSSI indication upon receiving valid packets
from remote units. It takes into consideration packets received from
both Repeaters and Remotes.
A Repeater will base its RSSI reading on valid packets received
from Slaves; if the Slaves are silent for 2 seconds, the Repeater will
display an RSSI value based on valid packets received from the
Master.
Signal strength is calculated based on the last four valid received
packets with correct CRC.
3.2.2 Rear
Collision LED (Amber)
Located at top/left of the ETHERNET connector, illuminates when
there is a collision on the ethernet interface.
Activity LED (Green)
Located at top/right of the ETHERNET connector, illuminates when
there is data activity present on the ethernet interface.
When initially cabling between
devices, pay close attention to
the Activity LED to confirm that
proper patchcable types are
being used.
