NOTE: It is highly recommended that you use a state-of-the-art modem and leave
it in its factory setting.
The default communication speed between the Excel 100C and the local
modem/ISDN* terminal adapter is 9600 BPS.
The communication speed between the Excel 100C and XBS modems/ISDN*
terminal adapters is automatically synchronized by the two devices to the highest
speed that both of the devices are capable of. This feature is called "autobauding"
and is a feature that all state-of-the-art modems/ISDN* terminal adapters provide
when left in their factory default settings.
The communication speed between the XBS and its modem/ISDN* terminal adapter
is part of the modem set-up at the XBS.
The Excel 100C will automatically detect whether the modem/ISDN* terminal
adapter is initialized in auto-answer or manu-answer mode, and it will set the
modem to manual answer mode (S0=0)
*ISDN NOTE: Communication via ISDN is applicable only for Europe.
For those cases where it is not clear if the modem to be used is in its factory setting,
the modem can be reset to its factory setting by using the RESET MODEM
command in the Start-Up sequence on the MMI. This will allow a quick and easy
modem reset without having to run the modem set-up software or the Windows™
terminal program.
The RESET MODEM command causes the following commands to be sent to the
modem:
1.
ATZ
executes hardware reset on modem
2.
AT&FX3&W
resets modem to factory configuration settings, configures the modem to not
wait for the public phone system dial tone, and writes this to non-volatile
memory.
If special modem/ISDN* terminal adapter behavior is required, the communication
device should be set up according to the instructions provided with it. This typically
involves running a setup program on a computer with the device connected to the
computer serial port or using the Windows™ terminal program.
*ISDN NOTE: Communication via ISDN is applicable only for Europe.
A common case of special modem behavior is when the modem is connected to an
in-house telephone network requiring a prefix to be dialed before the destination
number to provide access to the public telephone network. There are two important
aspects of the special initialization of the modem to consider:
1.
Do not wait for the public network dial tone. Typically, the init command ATX3
will trigger the modem to dial without waiting for a public network dial tone.
Save this modem set-up in the modem EEPROM with the command AT&W.
