Connection by

Request from a

Remote Device

The TSX ETG 1000 is the connection server.

If the TSX ETG 1000 module is configured for use with a modem, the module listens

for an incoming telephone connection request.

Once the telephone connection is established, the Username and Password (PAP)

are verified. If identification is unsuccessful, PPP communication is not established.

In this case the TSX ETG 1000 is the connection client.

Two types of modem connection can be opened:

l The SMTP mail server is configured for modem connection; the module opens

the connection automatically when an email is to be sent

l By register command from a module (see internal module register) (See

Internal

Module Registers, p. 27

); in this case the connection is opened when the request

is written

To open the connection, the module establishes a telephone connection by dialing

the telephone number configured for this remote device.

The TCP/IP connection to port 502 on the remote device is then opened

automatically by the TSX ETG 1000.

The remote device must be listed in the IP configuration table with its telephone

number, name and password.

UserName: USER

Password: USER

Note: The email connection takes priority over the command; if the IP address is

not the same, the email connection will close the current command. Otherwise the

command will wait for the end of the email connection (during the wait the status

assumes the value -1).
