◗ Frequency/Rate/Power

These options define the operating frequency, data rate and transmit power

for the module. The fields for these options include:

• Active Radio Frequency

This field displays the active radio frequency that this module is currently

using.

• Radio Frequency

This option allows you to manually change the operating frequency from

the frequencies available in the pull-down list. Alternatively, you can

choose the SmartSelect option which will instruct the system to select the

best frequency automatically.

• Data Rate

This option allows you to select the data rate for the wireless module

from the choices available in the pull-down list. All data rates are

specified in Mbps (Megabits per second). You can choose a specific data

rate from the pull-down list, or choose the Best option, which will

instruct the system to select the best data rate for the wireless module

automatically. The available data rates are determined by which type of

wireless module (802.11a or 802.11g) you are logged in to.

• Transmit Power

This option allows you to select the level of transmit power for the

wireless module from the choices available in the pull-down list (either

Full, Half, Quarter, One Eighth, or Minimum). You can decrease the

transmit power to decrease the range of the module. The default value for

this parameter is Full (maximum power).

Depending on the selected antenna(s) for your application—especially

relevant to the OWS—it may be necessary to configure the transmit

power. It is the installer's responsibility to ensure that the transmit power

is set correctly for the chosen antenna(s). Operation in a manner other

than is represented in this document is a violation of FCC rules.

For a complete listing of the maximum power settings allowed for

antennas, go to “Power Settings for Antennas” on page 167.
