NOTE : If power is removed from the unit while the Channel LED
Pattern is still active, no change in the units channel selection
will be made.
Changing the 802.11g Radio Channel
The WiRanger can operate on one of three 802.11g radio channels.
Each radio channel broadcasts data in a different frequency band within
the 2.4GHz range. The WiRanger can be configured to operate on
channels: 1, 6, and 11.
By selecting a different Radio Channel, you can try to find a channel
with minimal radio interference. This can improve signal quality and
data rates.
NOTE : When changing the Radio Channel for a “Paired” system, the
channel change MUST BE completed on BOTH the LEX
unit and the REX unit. The order is non-specific.
NOTE : STOP all devices connected to the REX unit prior to
changing the channel on either unit. Changing the Radio
Channel will disrupt USB traffic.
1. Power on either the LEX unit or the REX unit and wait for
approximately 20 seconds before proceeding to step 2. If the unit is
already on, proceed to step 2.
2. On the selected LEX unit or REX unit, press and hold (do not
release) the Pair/CH button for a minimum of 10 seconds. The
button can be released when the Host, Link and Activity LED’s
start to blink rapidly.
3. Upon release of the Pair/CH button the current 802.11g Radio
Channel will be displayed by as a pattern on the Host, Link, and
Activity LED’s. Please see the figure below for the description of
the LED Radio Channel patterns.
