CDA70 MODEM DESCRIPTION
31
2.17. Basic parameters description
For monitoring of status, configuration and administration of the modem is RADWIN
program [1]. In right under main menu is function list where is possible choice Configuration
(Ctrl + F1). Next table describes parameters of the tap Basic. Ports description is depend on
used protocol. Protocols description is possible to get from Conel Company.

Parameter description
Serial number
--- Modem serial number information.
RF module type
--- Radio module type information.
Operating RF
frequency
403,000 up to
470,000 MHz
Defines which frequency the modems will
communicates. The same value must be set
on modems which are supposed to
communicate mutually.
Channel spacing
12,5/20/25 kHz It is frequency distance (frequency
difference) between nominal frequencies
of two neighbouring radio channels. The
same value must be set on modems which
are supposed to communicate mutually.
RF power
0,01 up to 5 W Output RF power.
AF filter
Wide band/
Narrow band
When the Channel spacing is set to 12,5 kHz
than it is possible to set this parameter to the
Narrow band. Better sensitivity is typically
achieved by these settings. For other channel
spacing this parameter is set to the Wide
band and may not be changed.
Modulation inversion
YES/NO When this parameter is set on YES than it is
possible to invert transmitting signal. For
CDA-70 modems isn't signal inverted. This
parameter may not be changed.
Firmware version
--- Parameter shows modem firmware number,
only for information.
Modulation type
2-GMSK/
Combined/
4-FSK without
FEC/4-KSK
with FEC
This parameter defines the way modulation
signal will change the characteristics of
carrier frequency. The same modulation type
must be set on modems which are supposed
to communicate mutually.
