RF INTERFACE
The SATELLINE-EASy Pro 35W has a single TNC type RF-connector with impedance of 50 Ohm.
When the modem is supplied the frequency is set to “default channel”. The user can change the
frequency afterwards by 70 MHz. Of course, all local regulations set forth by the authorities must
be taken into consideration.
The data speed of the radio interface is set to “default speed”. It can also be set afterwards.
A channel spacing of 25 kHz enables a data speed of 19200 bps and a channel spacing of 12.5
/ 20 kHz enables, correspondingly, a data speed of 9600 bps. The data speed of the radio
interface is always fixed (19200 bps or 9600 bps) irrespective of the data speed of the serial
interface. If the data speeds of the radio interface and the serial interface differ from each other,
the radio modem will buffer the data in transfer temporarily, so no data loss will occur.

Transmitter
The output power of the transmitter is adjustable. The greatest allowable power depends on limits
set by local authorities, which should not be exceeded under any circumstances. The output
power of the transmitter should be set to the smallest possible level, which still ensures error free
connections under variable conditions. Large output power levels using short connection distances
can, in the worst case, cause disturbances to the overall operation of the system.
Table:Typical output power levels.
A product variant providing 5, 10, 20 and 25 W power levels is available by separate order.
NOTE!
Setting the radio data modem output power level to that which exceeds the regulations set forth
by local authorities is strictly forbidden. The setting and/or using of non-approved power levels
may lead to prosecution. SATEL and its distributors are not responsible for any illegal use of its
radio equipment, and are not responsible in any way of any claims or penalties arising from the
operation of its radio equipment in ways contradictory to local regulations and/or requirements
and/or laws.
