Basic configuration
Fields explanation:
The values into [ ] bracket indicate the permissible range or the ON/OFF condition to be setted into the
selected field. The value into ( ) bracket is the measure unit of the field parameter.
System Code [0....63]
: Define the identification code of a group of radiomodems. Obviously all
radiomodems of a specified group may have the
same
System Code.
RxFreq. (MHz):
Operating frequency of the receiver section. This value may be compatible with the
operative band and the variation step is
6.25 kHz
.
TxFreq. (MHz):
Operating frequency of the transmitter section. All previous considerations are valid for
TxFreq.
NOTE:
The insertion format of operating frequencies contains both integer and decimal.
For example if frequencies is
434.15625
MHz the displayed format is
434.156.25
. If the inserted value is not
an exact multiple of 6.25 kHz an internal routine in the configuration software shifts this value to the nearest
multiple of 6.25 kHz. Function keys
F5
and
F6
respectively decrease/increase this value by a step of 6.25
kHz.
Broadcasting [ON/OFF]:
Available only if both
ACK
and
Echo
functions are in
OFF Mode
. When selected
all transmitted packet are received by all radiomodems having the same System Code independently by their
target addresses. (See Advanced Help for more information).
Flow Control [ON/OFF]:
When selected the
CTS
criteria (Clear to Send) of RS232 serial port controls the
data flow from DTE. If inactive the CTS/RT485 output is the Rx/Tx switch of RS485 interface and in this case
the correct management of the intervals between data packet is a specific duty of DTE.
