ATTENTION
-

the incorrect connection of the wires or the inversion of poles
on the power supply may damage the apparatus

-

exceeding the maximum power supply value (12 VDC) may
damage the apparatus

-

the apparatus must run exclusively on batteries or on a
power supply protected against short circuits

-

the connection wires must not be connected to dangerous
voltages

-

The radiomodem RX pin must be wired to the computer TX pin or
vice versa.
The radiomodem SGND pin must be wired to the computer SGND.

Two or more devices can exchange data correctly only if all of the
parameters are the same on each device.
If the PAN ID or THE CHANNEL are different, the devices are
connected to different nets and they can’t exchange data.
