4.2.3.14 LED Mode
The LED Mode submenu controls the SNR bar's behavior. By default, the LEDs
indicate the SNR level, which facilitates antenna's alignment. However, it is also
possible to deactivate the LEDs or to customize the SNR bar to indicate when
specific thresholds for RSSI, SNR, CRC percentage and average modulation are
reached.
4.2.3.14.1 Change Mode
This submenu allows switching between the operation modes that are available
for the LEDs. The following options are available:
Normal mode: This is the default operation mode. The green LEDs on the bar

indicate the SNR level. See
information.
Threshold mode: This mode allows users to define a custom behavior for each

of the 8 SNR LEDs, based on the RSSI, SNR, CRC ratio or average modulation.
See
If all the thresholds that were set up are reached, the entire SNR bar will light
up. For instance if LEDs 2, 5 and 6 have thresholds set for them (the rest of
the SNR LEDs are disabled) and all these thresholds are reached, instead of
having only LEDs 2, 5 and 6 light up, all the SNR LEDs will light up.
Stealth mode: This setting completely shuts down all the SNR LEDs on the

unit's panel, leaving only the Status, Ethernet and W-Link indicators active.
4.2.3.14.2 Threshold Mode Settings
This submenu allows users to define the behavior for each LED in the SNR bar
when the Threshold Mode is employed.
4.2.3.14.2.1 LED 1 to 8
Selects the LED you wish to configure. You can define a threshold that must be
reached for the LED to light up by using the menus described below.
4.2.3.14.2.1.1Threshold Type
This option defines the parameter that is monitored and that the threshold is set
for:
Disabled: The LED is always off.

RSSI: Sets up a threshold for the Received Signal Strength Indication
