5.1.2 Sending Configuration Information
Firstly the configuration file for the radio needs to be setup. Using
MXTOOLS the configuration information needs to be filled out on the
Configuration Screen. This information needs to be saved to a configuration
file. If an existing radio already contains the desired configuration then this
configuration can be downloaded and saved. This configuration information
then needs to be ‘Sent to the MX800’. A warning message will appear that
indicates that the MX800 Base Station has not yet been calibrated, this may
be ignored.
Once the configuration information has been sent then all of the
programmable parameters within the MX800 Base Station are initialised.
5.1.3 Sending Channel Information
The channel information setup is similar to that of the configuration. The
channel frequencies, subtones and other parameters are setup in the Channel
Screen in MXTOOLS. At this stage it is not necessary to set the values of the
digital potentiometers. This will be done in the following procedures. After
entering in the channel details this information then needs to be saved to a
file. If another radio already contains the desired frequencies then these can
be downloaded from that radio and saved to a file. The digital potentiometer
values from one radio to the next will differ so it is advisable to save the
information in a new channel file and not save over the top of any backup
copies of existing radios. The saved channel information is then sent to the
MX800.
After sending the configuration and channel information the MX800 is fully
programmed and will now operate. Without sending both the configuration
and channel information the radio will not function, and thus the following
procedures will not be able to be completed.
Note
The buttons for sending and loading of channel information may be
disabled if MXTOOLS did not successfully ‘Connect to MX800’. If this
is the case simply choose to ‘Connect to the Radio’ after the
configuration information is sent.
5.1.4 Setting Alignment Channel
When setting up the radio it is recommended that all measurement and
adjustments are done on a channel that is in the centre of the frequency
spread of the channels. This minimises any errors due to frequency changing.
Alternatively if the frequency spread of the channels is too large then you
may wish to calibrate and align every channel. (In most cases this will not be
necessary.) Both individual and group alignment will be covered.
The channel may be selected via the Channel Screen in MXTOOLS using the
software channel select or in hardware via the internal channel DIP switch or
via the rear channel select. (Refer to section 2.2.2.3 for additional help.) This
channel will then be used when performing the following procedures.
