The operating parameters of these modems (serial link, radio management…)
can be updated through commands on the serial link.
The products are available either in card version to be integrated in an
assembly or as an IP65 chip. In the IP65 case, the products are fixed with
the fixing lugs onto the top (antenna) and bottom (stuffing box) of the casing
(4 screws not provided).
