Status LEDs
cnReach radios have LINK*, XMIT* and RCV* LEDs on the front for each of radio 1 and radio 2.
The LINK LED shows radio power and link state.
•
A
red
LINK LED indicates that the radio has power but is not linked (a Point to Multipoint
Access Point radio always shows a
green
LINK LED. All other radio configurations show a
red
LINK LED upon power up until the radio link is established).
•
A
green
LINK LED indicates that the radio has power and is linked.
•
When the link is established the LINK LED turns
green
.
•
If the link is dropped, then the LINK LED returns to
red
.
The XMIT LED flashes
red
every time the radio transmits data.
The RCV LED flashes
green
when the radio is receiving and decoding an RF packet
.
Because of the high speed of the embedded microprocessor and communications, all status LEDs can
turn on and off very quickly. In some cases, the LEDs turn on and off so quickly that the LEDs appear to
be on but dimly lit. This behaviour indicates that events are happening in very quick succession. A good
example is the XMIT LED changing intensity from dim
red
to bright
red
to off. This indicates many small
packets in quick succession (dim
red
), followed by many large packets with almost continuous
transmissions (bright
red
), then no transmissions (off).
