Cooper Bussmann 945U-E Wireless Ethernet Modem & Device Server User Manual
Rev Version 2.14
Radio Mode
The 945U-E only supports the 802.11 standard.
Transmit Power Level
This allows adjustment of the radio power. Do not set the radio power above
the allowed setting for your country You can reduce the power for short range
applications, or to allow the use of high gain transmitter antennas while still
complying with the emission requirements of your country. See “Appendix C -
POWER CONVERSION” for dBm to mW conversion.
Channel (AP Only)
Select available channel, frequency and bandwidth from drop down list. Different
regions will show the channels available for that region.
Channel Width
Used when configuring clients (STA). A Client will scan for available access points
that it can then connect with. Selecting a Channel Width will limit the number of
channels the client will scan. For example, if “5 MHz” is selected the client will only
scan the 5-MHz channels. If “Auto” is selected, it will scan all channels and all bands
(default is Auto).
Transmit Data Rate
The radio baud rate in Mega (million) bits per second (Mbps) for point-to-point radio
transmissions. The default value is Auto. Select a fixed rate to force the radio to use
the selected rate.
NOTE Fixing the TX Rate is not recommended except for advanced users.
The Transmit Data Rate only applies to the transmit messages; the radio can
receive on all data rates.
Increasing the Transmit Data rate will decrease the transmit power level. For
example, a 36-Mbps data rate will reduce the TX power to 400 mW, a 48-Mbps data
rate will reduce the power to 200 mW, and 54-Mbps data rate will reduce the power
to 125 mW.
Basic Rate
This is the default data rate that the access point uses when sending beacons,
management frames, and all broadcast or multicast frames.
Beacon Interval
(AP only)
This interval is the period between beacon transmissions sent by an access point.
The default value is 100 milliseconds, and it may be adjusted from 50 to 4095
milliseconds.
Max Distance
Configure the maximum distance the radio signal is expected to travel. This allows
the modem to compensate for the flight time of messages as they pass from the
transmitter to the receiver, and as the acknowledgment messages are returned.
Setting this value larger will cause a small reduction in throughput. Setting this
value too small will cause communications problems over longer distances. Default
distance is 20 km.
Disable SSID
broadcast (AP only)
This should be used to prevent unwanted eavesdroppers from detecting the radio
network system address (SSID) by passively listening to beacon transmissions from
the access point. When disabled, access points will not transmit the system address
openly in beacon messages. This is particularly useful in unencrypted radio networks.
Save Changes
Save changes to non-volatile memory. Changes will not take effect until module is
reset.
Save Changes and
Reset
Save changes to non-volatile memory and reset module.
Channel Selection
945U-E (900MHz 802.11) channel selection is performed by selecting the appropriate channel from the drop down
list. Only channels available for that region will be available.
