Programming with the terminal software
First set your terminal program to the appropriate data transmission rate and data format for read-
ing the target device (i.e. meter). Use one of the AT commands (e.g. ATS0?, ATI, AT&V) to check
whether the modem answers. If you see the answer on the screen, the interface is working cor-
rectly.
Note:
Simply typing „AT“ does not result in an answer, because the modem is by default pro-
grammed not to send messages and echoes (Parameters ATQ1 and ATE0).
At the end of every programming the settings have to be saved permanently using the AT&W
command. This ensures that the parameters are restored after power failure.
Find below some examples of AT commands (the answers depend upon the respective firmware
version):

Set all parameters to factory defaults.
ats0=n
OK
This parameter setting determines the number of rings
(0 to 255) before automatic answering.
e.g.: ats0=1 (Modem answers after first ring)
Attention: ats0=0 disables automatic answering!
at#dtc=n
OK

atd Address>: CONNECT Dial (dialling string) The modem lifts up and dials in accordance with the dialling string given by the atd command, e.g.: atd192.168.1.220:1234 +++ OK Disconnect After the escape sequence +++ the modem hangs up. ate0 OK This disables the modem to send echoes of charac- ters received from PC during command state atv0 0 Result is presented as number (atv1: as text) atq1 No answer This parameter setting disables transmission of result codes to the PC. Information text transmitted in re- sponse is not affected by this setting
