The M400E can be connected to and operated over the Internet through a modem.
This requires a db-9 female to db-25pin male cable (available from T-API as p/n
WR0000024).
Once the cable has been connected, check to make sure the DTE-DCE is in the
correct position. Also make sure the model 400E COM port(s) are set for a Baud
Rate (see Section 6.9.6) that is compatible with your device and that your device
operates with an 8-bit word length wit one stop bit.
The first step is to turn on the MODEM ENABLE communication mode (see
Section 6.9.4). Once this is completed the appropriate SETUP command line for
your modem can be entered into the analyzer. The default setting for this feature
is:
