Frequently used settings for PLC-systems
and industrial applications.
Most PLC-systems and other industrial applications require the same changes to the stan-
dard settings.
The most commonly encountered problems concern speed, parity and control signals from
the connected equipment.
Speed and parity are changed with the switches under the cover. If this action does not
solve the problem the modem’s answering codes and possible echoing of commands
might be the source of the difficulty. Here below follows a list of commands that might
resolve the problems. (The commands may of course be placed on one single command
line if desired, as per the example1):
ATV
Gives the answering codes in short format. (digits)
ATQ1
No result codes are sent on the RS-232/V.24 connection.
ATE
Commands that are sent from the terminal/computer etc.
are not echoed back to the RS-232/V.24 connection.
AT&C1
DCD will follow the ISDN line status DCD on when ID-90
has detected and synchronised to the ISDN line.
AT&K
No handshaking.
AT**dabort=0Dialing, answering is not aborted by characters from DTE.
For further information regarding these commands please refer to the specific section of
this manual.
