Radio Configuration 3.7
Figure 33 - Radio Config
The Radio Configuration page is where configuration parameters associated with the radio can be adjusted or configured.
The first time out of the box configuration will run a configuration wizard that will step you through some radio questions
that will allow you to select radio configuration for your country of operation and license.
The factory-default parameters of the radio will be set to values that will allow the radio to be powered up safely, without it
interfering with radio equipment that may be available in the country of operation. I.e. transmit and receive frequencies will
be set to zero.
After the initial out of the box configuration you will be able to configure available radio parameters by selecting the
page. When all changes are made, you will & Activate the changes.
Radio Menu
Radio Bandwidth
This is the Bandwidth of the radio and it is factory set. It will be either 12.5KHz
(narrow band) or 25Khz (wide band)
Transmit Power Level
This allows adjustment of the radio power. Do not set the radio power above the
allowed setting for your country or radio license. 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 license.
See Appendix F -
Transmit Data Rate
The 450U-E can be configured for different radio transmission rates. Note:
reducing in the configured data rate may increases the reliable range of the
module (transmission distance).
The radio baud rate in kilobits per second (kbps) for point to point radio
transmissions. Select a fixed rate for the radio to use from the drop down list.
Selections available are 9600 and 19200 kbps for 25KHz wide band or 4800 &
9600 kbps for 12.5KHz narrow band.
The Transmit Data Rate only applies to the Transmit messages as the radio can
receive on either data rate.
Frequency Step Size
The Frequency Step size is the spacing between frequencies that you can select
when configuring the TX and RX frequencies. The steps sizes available are 5Khz or
6.25KHz.
Transmit Frequency
The Frequency that you wish to configure for the radio Transmitter. Frequency
selection will be in multiples of the frequency step configured in the previous
parameter. E.g. 450.00500, 450.01000, 450.01500, 450.02000, etc. for 5Khz or
450.00625, 450.01250, 450.01875, 450.02500, etc. for 6.25KHz frequency step
size.
