3.4 MODEM INITIALIZATION STRING
PURPOSE:
Used to choose whether the default or a custom initialization “string” is
sent to confi gure the modem (a “string” is a series of characters that
are commands for the modem). Modem’s use initialization strings to
setup their speed, data type, and other options. The RA-2400 sends the
initialization string to the modem before using the modem to connect to
the DVS-2400.
☞ NOTE: There are hundreds of models of modems available,
each with unique characteristics. Instead of using the default
modem string, some modems may perform better with a custom
initialization string.
USER RESPONSE:
✦ Leave USE DEFAULT INITIALIZATION STRING option selected unless
you are having trouble connecting with your modem.
✦ IF YOU ARE HAVING TROUBLE CONNECTING WITH YOUR
MODEM, and it tests OK with the Windows modem test diagnostics
(see Section 1.5), try using a custom initialization string. Various
model modems have different requirements for initialization strings.
Refer to your modem’s manual for the required commands to place
the modem in 300 BAUD BELL 103 confi guration. Two examples
are “&F1&N1” and “N0S37=1”. If the initalization string is incorrect,
the RA-2400 will display “ERROR WRITING INITIALIZATION
STRING”.
☞ NOTE: When entering a custom initialization string, don’t enter the
“AT” command. The RA-2400 program will do this automatically.
