8.4.4) MODEM

CONNECTION

To make the remote connection it needs to program the remote modem (connected to the EMA
network). To program this modem the user has to use any communication program like
HyperTerminal. The Hayes commands to program a standard modem are the following:

AT&D0&S0&C0&R1
ATS0=2
ATX3
AT&W0Y0

The meaning of the commands is the following (AT is the command prefix):

•

&D0: ignore DTR.

•

&S0: ignore DSR.

•

&C0: ignore CD.

•

&R1: ignore RTS.

•

S0=2: set at two as the ring number after the which the modem automatically reply (the number can

be different by 2, but it must be different by 0).

•

&W0: store the configuration in the register 0 of the modem’s not volatile memory.

•

Y0: set the configuration stored in the register 0 of the modem’s not volatile memory as the default

configuration at the starting or the reset of modem.

See the modem’s user manual.

It’s possible to manage the supervisioning of energy

consumption through remote structures as modem

application in order to cover big distances.
