No Radio Link
If the Link Quality indicator in the Radio Status panel shows 0%, check the
following for possible causes:
• Make sure that the Signal Strength indicator under Radio Status panel is
not zero. A minimum of 20% is recommended. If the “Signal Strength” is
less than 20%, the distance between the WiSER2400 and the targeted AP
may be too far. Decrease the distance between the radio pair to see if the
radio link can be improved.
• Make sure that the encryption keys are entered correctly if WEP
encryption is enabled.
• Make sure that there is no RF interference present in the radio network.
No Data Transfer While the Radio Link is Good
If the Link Quality indicator shows good link quality, but the host
computer/equipment cannot properly exchange data:
• Make sure the RS232 cable are properly connected to the radio and
computer/equipment.
• Make sure that the RS232 cable in use are not defective.
