Power LED does not turn On.
Check power connector is properly inserted.
Power LED turns Red.
Remove power and re-apply. If the Power LED
remains Red, contact Quatech, Inc.
Power LED is Amber.
Bridge has not established an IP address either
through DHCP or Static methods.
DHCP is the default method by which the unit
obtains an IP address. Your network must have a
DHCP server available when the bridge is powered-
up. Most AP/Routers have a DHCP server built-in.
Enable your DHCP server and re-start the module.
Link LED continues to Blink Red.
Bridge has not found an Access Point with which to
associate. Be sure the Access Point you want to
use is turned on and has WEP and WPA disabled
(you can enable WEP or WPA after the Bridge has
been configured).
If this does not help, be sure there are no nearby
devices causing interference. If there are, either turn
off or move the device causing the interference or
move the Bridge and Access Point to another
location.
Comm LED is Off or Amber.
Be sure a serial device is connected to the Bridge
and that the device is turned on.
Comm LED is Red and Link LED is
Green but you are unable to pass
data.
No open TCP socket is recognized by the Bridge.
Be sure you have an open TCP connection to the
bridge and the connection is in data pass mode.
